Aortic Rupture: The tearing or bursting of the wall along any portion of the AORTA, such as thoracic or abdominal. It may result from the rupture of an aneurysm or it may be due to TRAUMA.Rupture: Forcible or traumatic tear or break of an organ or other soft part of the body.Deceleration: A decrease in the rate of speed.Aortography: Radiographic visualization of the aorta and its branches by injection of contrast media, using percutaneous puncture or catheterization procedures.Aneurysm, Dissecting: Aneurysm caused by a tear in the TUNICA INTIMA of a blood vessel leading to interstitial HEMORRHAGE, and splitting (dissecting) of the vessel wall, often involving the AORTA. Dissection between the intima and media causes luminal occlusion. Dissection at the media, or between the media and the outer adventitia causes aneurismal dilation.Aortic Aneurysm, Thoracic: An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. This proximal descending portion of aorta gives rise to the visceral and the parietal branches above the aortic hiatus at the diaphragm.Blood Vessel Prosthesis Implantation: Surgical insertion of BLOOD VESSEL PROSTHESES to repair injured or diseased blood vessels.Wounds, Nonpenetrating: Injuries caused by impact with a blunt object where there is no penetration of the skin.Thoracic Injuries: General or unspecified injuries to the chest area.Aortic Aneurysm: An abnormal balloon- or sac-like dilatation in the wall of AORTA.Splenic RuptureAorta, Thoracic: The portion of the descending aorta proceeding from the arch of the aorta and extending to the DIAPHRAGM, eventually connecting to the ABDOMINAL AORTA.Heart Rupture: Disease-related laceration or tearing of tissues of the heart, including the free-wall MYOCARDIUM; HEART SEPTUM; PAPILLARY MUSCLES; CHORDAE TENDINEAE; and any of the HEART VALVES. Pathological rupture usually results from myocardial infarction (HEART RUPTURE, POST-INFARCTION).Aortitis: Inflammation of the wall of the AORTA.Aortic Aneurysm, Abdominal: An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.Blood Vessel Prosthesis: Device constructed of either synthetic or biological material that is used for the repair of injured or diseased blood vessels.Uterine Rupture: A complete separation or tear in the wall of the UTERUS with or without expulsion of the FETUS. It may be due to injuries, multiple pregnancies, large fetus, previous scarring, or obstruction.Stents: Devices that provide support for tubular structures that are being anastomosed or for body cavities during skin grafting.Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Aneurysm, False: Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.Aortic Diseases: Pathological processes involving any part of the AORTA.Vascular Surgical Procedures: Operative procedures for the treatment of vascular disorders.Ulcer: A lesion on the surface of the skin or a mucous surface, produced by the sloughing of inflammatory necrotic tissue.Heart Rupture, Post-Infarction: Laceration or tearing of cardiac tissues appearing after MYOCARDIAL INFARCTION.Fatal Outcome: Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients.

Preterm PROM is membrane rupture before 37 weeks of GESTATION.Aorta, Abdominal: The aorta from the DIAPHRAGM to the bifurcation into the right and left common iliac arteries.Accidents, Traffic: Accidents on streets, roads, and highways involving drivers, passengers, pedestrians, or vehicles. Traffic accidents refer to AUTOMOBILES (passenger cars, buses, and trucks), BICYCLING, and MOTORCYCLES but not OFF-ROAD MOTOR VEHICLES; RAILROADS nor snowmobiles.Surgical Procedures, Minimally Invasive: Procedures that avoid use of open, invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device.Hematoma: A collection of blood outside the BLOOD VESSELS. Hematoma can be localized in an organ, space, or tissue.Endovascular Procedures: Minimally invasive procedures, diagnostic or therapeutic, performed within the BLOOD VESSELS. They may be perfomed via ANGIOSCOPY; INTERVENTIONAL MAGNETIC RESONANCE IMAGING; INTERVENTIONAL RADIOGRAPHY; or INTERVENTIONAL ULTRASONOGRAPHY.Rupture, Spontaneous: Tear or break of an organ, vessel or other soft part of the body, occurring in the absence of external force.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Reoperation: A repeat operation for the same condition in the same patient due to disease progression or recurrence, or as followup to failed previous surgery.Acute Disease: Disease having a short and relatively severe course.Retrospective Studies: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.Aneurysm, Ruptured: The tearing or bursting of the weakened wall of the aneurysmal sac, usually heralded by sudden worsening pain. The great danger of a ruptured aneurysm is the large amount of blood spilling into the surrounding tissues and cavities, causing HEMORRHAGIC SHOCK.Aorta: The main trunk of the systemic arteries.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Stomach Rupture: Bursting of the STOMACH.Tendon Injuries: Injuries to the fibrous cords of connective tissue which attach muscles to bones or other structures.Follow-Up Studies: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.Hemoperitoneum: Accumulations of blood in the PERITONEAL CAVITY due to internal HEMORRHAGE.Achilles Tendon: A fibrous cord that connects the muscles in the back of the calf to the HEEL BONE.Intracranial Aneurysm: Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES.

Ruptured abdominal aortic aneurysms: selecting patients for surgery. (1/892)

OBJECTIVES: Mortality from ruptured abdominal aortic aneurysm (RAAA) remains high. Despite this, withholding surgery on poor-prognosis patients with RAAA may create a difficult dilemma for the surgeon. Hardman et al. identified five independent, preoperative risk factors associated with mortality and proposed a model for preoperative patient selection. The aim of this study was to test the validity of the same model in an independent series of RAAA patients. METHODS: A consecutive series of patients undergoing surgery for RAAA was analysed retrospectively by case-note review. Thirty-day operative mortality and the presence of the five risk factors: age (> 76 years), creatinine (Cr) (> 190 mumol/l), haemoglobin (Hb) (< 9 g/dl), loss of consciousness and electrocardiographic (ECG) evidence of ischaemia were recorded for each patient. RESULTS: Complete data sets existed for 69 patients (mean age: 73 years, range: 38-86 years, male to female ratio: 6:1). Operative mortality was 43%. The cumulative effect of 0, 1 and 2 risk factors on mortality was 18%, 28% and 48%, respectively. All patients with three or more risk factors died (eight patients). CONCLUSIONS: These results lend support to the validity of the model. The potential to avoid surgery in patients with little or no chance of survival would spare unnecessary suffering, reduce operative mortality and enhance use of scarce resources.  (+info)

Repair of ruptured thoracoabdominal aortic aneurysm is worthwhile in selected cases. (2/892)

INTRODUCTION: The risks and benefits of operating on patients with ruptured thoracoabdominal aortic aneurysm (TAAA) have not been defined. The aim of the present study is to report this unit's experience with operations performed for ruptured TAAA over a 10-year period. METHODS: Interrogation of a prospectively gathered computerised database. PATIENTS: Between 1 January 1983 and 30 June 1996, 188 consecutive patients with TAAA were operated on, of whom 23 (12%) were operated for rupture. RESULTS: There were nine survivors (40%). Patients whose preoperative systolic blood pressure remained above 100 mmHg were significantly more likely to survive (4/8 vs. 13/15, p = 0.03 by Fisher's exact test). Survival was also related to Crawford type: type I (two of three survived); II (none of six); III (two of six); and IV (five of eight). All non-type II, non-shocked patients survived operation. Survivors spent a median of 28 (range 10-66) postoperative days in hospital, of which a median of 6 (range 2-24) days were spent in the intensive care unit. Survivor morbidity comprised prolonged ventilation (> 5 days) (n = 3); tracheostomy (n = 1); and temporary haemofiltration (n = 2). No survivor developed paraplegia or required permanent dialysis. CONCLUSIONS: Patients in shock with a Crawford type II aneurysm have such a poor prognosis that intervention has to be questioned except in the most favourable of circumstances. However, patients with types I, III and IV who are not shocked on presentation can be salvaged and, where possible, should be transferred to a unit where appropriate expertise and facilities are available.  (+info)

Rupture of aortic aneurysm with right-sided haemothorax. (3/892)

A 62-yr-old male with a history of high blood pressure was admitted for persistent dyspnoea and a right-sided pleural effusion, complicated by a recent episode of shock. There was no history of trauma and the patient denied any thoracic pain. A chest tube was inserted which released nonclotting bloody fluid. A thoracic computed tomographic scan of the chest revealed an aneurysm of the inferior third of the descending thoracic aorta. The patient underwent a successful prosthetic graft replacement. We emphasize that rupture of aortic aneurysms should be considered in the evaluation of spontaneous haemothorax even if it is right-sided and not associated with pain.  (+info)

Frame dislocation of body middle rings in endovascular stent tube grafts. (4/892)

OBJECTIVES: To understand the cause, and propose a mechanism for frame dislocation in endovascular grafts. MATERIALS AND METHODS: Five tube grafts were explanted due to secondary distal leakage 15-21 months after operation. One bifurcated graft was removed during emergency operation after aortic rupture caused by secondary leakage. A second bifurcated graft was harvested from a patient with thrombotic occlusion of one limb, who died after transurethral prostatic resection. The inside of the grafts were examined endoscopically. The stent was inspected after removal of the fabric, broken ligatures were counted and examined by scanning electron microscopy. The fabric strength was tested by probe puncture. RESULTS: We found 17-44% of the stent ligatures of the body middle rings to be loose. The knots were intact. Degradation of the polyester textile was not observed. CONCLUSIONS: Continuous movements in the grafted aorta and blood pressure impose permanent stress to the stent frame and the polyester fabric resulting in morphological changes in the body middle ring of grafts. The clinical implications of the suture breakages are unknown although they may be related to distal secondary leakage in tube grafts.  (+info)

Acute renal impairment due to a primary aortocaval fistula is normalised after a successful operation. (5/892)

OBJECTIVES: To study renal function in patients with aortocaval fistula, before and after surgery. DESIGN: Retrospective study. MATERIAL AND METHODS: During the last 22 years nine male patients (median age 67, age range 50-72) with spontaneous aortocaval fistula in combination with AAA were operated upon. This constitutes 4% of the patients with ruptured AAA and 1.5% of all patients with AAA. RESULTS: A preoperative diagnosis of aortocaval fistula was established in three of the nine cases. The medium duration of symptoms prior to surgery was 5 days (range 4 h-14 days). The fistula was combined with an extravasating ruptured AAA in only three patients. Seven of the patients had acute renal insufficiency, with creatinine levels of in median 292 mumol (IQR 218-342). Creatinine declined to 172 mumol/l (IQR 170-313) on the fifth postoperative day in uncomplicated cases and to 86 mumol at discharge. One patient died due to multi-organ failure, whereas the other left hospital well and alive with normal renal function. CONCLUSION: Acute preoperative renal insufficiency due to an aortocaval fistula in patients with AAA is often due to venous congestion, and is normalised after successful surgery.  (+info)

Mortality in ruptured abdominal aortic aneurysms. The Finnvasc Study Group. (6/892)

OBJECTIVE: To assess mortality related to rupture of abdominal aortic aneurysm (RAAA). DESIGN: A 4-year cross-sectional study based on a nationwide vascular registry Finnvasc and national cause-of-death registry (Statistics Finland). MATERIALS AND METHODS: A total of 454 operations for RAAA among 11,747 surgical vascular reconstructions recorded in the Finnvasc registry and 1004 deaths due to RAAA during the same period based on Statistics Finland. RESULTS: The operative mortality rate was 49% based on the Finnvasc registry and 54% based on Statistics Finland. With all RAAA deaths at hospitals included, total hospital mortality was 68%. No association existed between hospital volume of RAAA operations and surgical mortality, although an inverse association did exist between hospital volume of RAAA operations and all RAAA deaths in the hospital (p = 0.01). The case fatality for RAAA in Finland was 80%. CONCLUSIONS: RAAA surgical mortality calculations for RAAA, based on a vascular registry, underestimate the true rate because some cases with fatal outcome tend to escape registration. Because surgical mortality rates may also be skewed by patient selection, total hospital RAAA mortality thus represents the results of RAAA treatment more accurately.  (+info)

Chronic aneurysm of the descending thoracic aorta presenting with right pleural effusion and left phrenic paralysis. (7/892)

A 62-year-old man was admitted to the emergency department with chronic dysphagia and lower back pain. Chest radiography revealed a wide mediastinal shadow and an elevated left diaphragm, which proved to be secondary to left phrenic paralysis. The patient was diagnosed with an aneurysm of the descending thoracic aorta and was admitted to the hospital. After the patient was admitted, the aneurysm ruptured into the right chest. The patient underwent an emergency operation to replace the ruptured segment with a synthetic graft. Postoperative recovery and follow-up were uneventful. This report describes an unusual presentation of a thoracic aortic aneurysm. Hemidiaphragmatic paralysis caused by compression of the phrenic nerve is an unusual complication that, to our knowledge, has not been previously reported.  (+info)

Ruptured abdominal aortic aneurysm in the Huntingdon district: a 10-year experience. (8/892)

A study was undertaken to establish the true incidence of ruptured abdominal aortic aneurysms (RAAA) in the Huntingdon districts. RAAAs in the Huntingdon district between 1986 and 1995 were studied retrospectively. Data were collected from hospital records and hospital and community autopsies. There was a total of 139 cases of RAAA; 119 were males and 20 females, giving a M:F ratio of 6:1. The incidence of RAAAs was 17.8/100,000 person years (py) in males and 3.0/100,000 py in females. Mean age at rupture was 75.5 years in men (95% confidence intervals (CI) 74-78 years) and 80.2 in women (95% CI 78.8-83 years). There was an age-specific increase in incidence after the age of 65 years in men and after 80 years in women, although 12.6% of all RAAAs occurred in men under 65 years. In all, 100 patients were confirmed to have died of RAAA during the 10-year period. This represents 79% of all ruptures discovered. Almost three-quarters of patients did not reach the operating theatre. Of the 61 patients operated on, 29 survived (48%). The size of the aneurysm at rupture was recorded in 68 cases (49%). The mean size was 8.14 cm (SD 2.0 cm). In five cases (7.4%), rupture occurred in AAAs smaller than 6 cm. The overall mortality from RAAA in Huntingdon health district is approximately 80% and three-quarters of all deaths occurred without an operation.  (+info)

As you mentioned in your letter, if an abdominal aortic aneurysm ruptures, the mortality rate is very high - at least 50 percent, even if surgery is done promptly. Therefore, it is always better to repair them before they rupture. The trick is in figuring out which ones are most likely to rupture, since the surgery is complicated and people with these aneurysms are often elderly and have other medical problems that make them poor surgical risks.. The normal abdominal aorta measures no more than 2 centimeters in diameter on ultrasound. Anything larger would be considered an aneurysm, but aneurysms smaller than 4 cm in diameter rarely rupture. A recent Mayo Clinic study reported no ruptures of aneurysms smaller than 4 centimeters; one percent per year for aneurysms 4-5 centimeters in diameter; and 11 percent per year for aneurysms 5-6 centimeters in diameter. Another text that I checked reported a slightly higher rupture rate of aneurysms larger than 4 centimeters.. So the decision to do surgery ...

Introduction: Smoking cessation is one of the few available strategies to decrease the risk for expansion and rupture of small abdominal aortic aneurysms (AAAs). The cost-effectiveness of an intensive smoking cessation therapy in patients with small AAAs identified at screening was evaluated. Methods: A Markov cohort simulation model was used to compare an 8-week smoking cessation intervention with adjuvant pharmacotherapy and annual revisits vs nonintervention among 65-year-old male smokers with a small AAA identified at screening. The smoking cessation rate was tested in one-way sensitivity analyses in the intervention group (range, 22%-57%) and in the nonintervention group (range, 3%-30%). Literature data on the effect of smoking on AAA expansion and rupture was factored into the model. Results: The intervention was cost-effective in all tested scenarios and sensitivity analyses. The smoking cessation intervention was cost-effective due to a decreased need for AAA repair and decreased rupture ...

An abdominal aortic aneurysm (AAA) is when the lower part of the aorta becomes enlarged, like a balloon. The aorta is the largest artery in the body. It carries blood from the heart down along the backbone where it splits into many smaller arteries that bring blood to all of the organs. Aneurysm is a general term that describes an enlargement of any blood vessel in the body. Aneurysms usually develop slowly over time and may not cause problems until they become so enlarged that they can rupture.. Smaller AAAs generally do not cause symptoms. Larger AAAs can cause symptoms such as a pulsating feeling near the belly button, deep and constant abdominal pain, or back pain. Rupture of an aortic aneurysm is a medical emergency. If an aortic aneurysm ruptures, symptoms include vomiting, intense pain, excessive sweating, a drop in blood pressure, fainting, and shortness of breath.. AAAs can be caused by stiffening of the artery walls due to plaque build up (atherosclerosis), infection of the aorta, or ...
Long-term outcome of ruptured abdominal aortic aneurysm: impact of treatment and age Jelle W Raats,1 Hans C Flu,1 Gwan H Ho,1 Eelco J Veen,1 Louwerens D Vos,2 Ewout W Steyerberg,3 Lijckle van der Laan1 1Department of Surgery, Amphia Hospital, Breda, 2Department of Radiology, Amphia Hospital, Breda, 3Department of Public Health, Erasmus MC, Rotterdam, the Netherlands Background: Despite advances in operative repair, ruptured abdominal aortic aneurysm (rAAA) remains associated with high mortality and morbidity rates, especially in elderly patients. The purpose of this study was to evaluate the outcomes of emergency endovascular aneurysm repair (eEVAR), conventional open repair (OPEN), and conservative treatment in elderly patients with rAAA.Methods: We conducted a retrospective study of all rAAA patients treated with OPEN or eEVAR between January 2005 and December 2011 in the vascular surgery department at Amphia Hospital, the Netherlands. The outcome in patients treated for rAAA by eEVAR or OPEN repair
Despite encouraging results from the biomechanical AAA rupture risk assessment [12-16], the uncertainty of biomechanical predictions due to the uncertainty of input information remains a challenging limitation. Like other failure events, AAA rupture is also complex and a probabilistic risk assessment could have some advantages over a purely deterministic approach. We applied a well-established probabilistic method [36] and introduced PRRI, a novel and straightforward probabilistic AAA rupture risk indicator. Most important, PRRI discriminated better between ruptured and intact AAA cases than the state-of-the-art deterministic biomechanical method (discriminative power of 0.837 versus 0.673), and reached, although only for our very small cohort, statistical significance (p = 0.041 compared to p = 0.328 for PWRI from A4clinics Research Edition). A4clinics Research Edition proportionally adjusts the wall thickness to the patients blood pressure, such that the elevated blood pressure in our ...
We report the effect of kinin agonist and antagonist peptides on experimental aortic aneurysm. In vivo and in vitro data are presented to support a contributing role for B2R signaling in aortic wall weakening.. Medical treatment for aortic aneurysm aims to limit the main complication of aneurysm rupture. Aneurysm diameter is an important clinical indicator of rupture risk for AAA and is routinely used in the selection of patients for surgical intervention.25 We used the AngII-infused ApoE−/− mouse model of aortic aneurysm in which arterial inflammation and breaks in medial elastic lamellae lead to acute aortic rupture in ≈30% of mice.26 This model allowed the assessment of both survival free from aortic rupture and maximum aortic diameter. The main findings of this study were that administration of a B2R agonist enhanced the response to AngII and increased aortic rupture in our mouse model, whereas a B2R antagonist reduced aortic dilatation and rupture.. The findings of our study align ...
Any time you experience chest pain just not right in your chest, consult a medical professional. If you notice a strong pulse sensation, or a pulsating bulge in your abdomen, you should see your health care provider right away. If the pain is new, severe, frightening, or feels to be tearing or ripping, go immediately to a hospital emergency department. Do not wait it out; immediate treatment can be life saving for aneurysm/dissection as well as in other conditions that cause chest pain. If an aortic aneurysm ruptures, internal bleeding occurs. This is a medical emergency, because a person can bleed to death in a few minutes. Severe back, flank, or Abdominal pain may be the only symptom of an enlarging aorta. Many other conditions can cause these symptoms, but an aortic aneurysm is the most serious of these conditions. ...
Abdominal aortic aneurysm (AAA) rupture represents a major cardiovascular risk, combining complex vascular mechanisms weakening the abdominal artery wall coupled with hemodynamic forces exerted on the arterial wall. At present, a reliable method to predict AAA rupture is not available. Recent studies have introduced fluid structure interaction (FSI) simulations using isotropic wall properties to map regions of stress concentrations developing in the aneurismal wall as a much better alternative to the current clinical criterion, which is based on the AAA diameter alone. A new anisotropic material model of AAA that closely matches observed biomechanical AAA material properties was applied to FSI simulations of patient-specific AAA geometries in order to develop a more reliable predictor for its risk of rupture. Each patient-specific geometry was studied with and without an intraluminal thrombus (ILT) using two material models-the more commonly used isotropic material model and an anisotropic ...
I write a lot pregnabcy yahoo answers and some abdominal aortic aneurysm after pregnancy the things that young people think will stop them becoming pregnant are incredibly naпve - its scary how uninformed they are. Women need to measure their body temperature every morning, before arising. Read this article to learn why French women are encouraged to give birth and what are the anurysm in giving birth. What I like abdominal aortic aneurysm after pregnancy this calendar is that it shows how the days repeat. However, hair loss during pregnancy is completely normal and is said to occur due to fluctuating hormones in the body. Family history: Women with a aortkc history aorttic ovarian cancer, or breast cancer are aneuryysm prone to the chance of developing ovarian cancer compared to other women. Apparently, Dutch fathers have been in the scene of aneuryzm abdominal aortic aneurysm after pregnancy a long time as can be observed in paintings from the 17th and 18th centuries.

Background. Endovascular aneurysm repair (EVAR) has been claimed to decrease periprocedural mortality for treatment of abdominal aortic aneurysms with suspected rupture (rAAA). However the benefit of EVAR in true clinical emergencies (plain ruptured AAA) is still uncertain. This study aimed to analyze immediate and mid term outcomes of true rAAA treated in emergency.. Methods. All patients treated for rAAA from 2006 to 2010 were reviewed. Our policy is to perform an immediate computed tomography (CT) in emergency room (ER) for all patients with suspected rAAA. Only patients with evident aneurysm rupture on imaging were selected for this study. EVAR feasibility was left to the discretion of the operative specialized team available 24hours/day. Stability of EVAR repair was assessed with pre-discharge CT-scan.. Results. A total of 66 patients with plain rAAA were treated in emergency: 23 underwent EVAR and 43 open surgery. At baseline there was an equal distribution of physiologic characteristics ...
The US Preventative Services Task Force (USPSTF)have recommended that men aged 65 to 75 who have ever smoked should get an ultrasound to screen for Abdominal Aortic Aneurysm (AAA).. Why is screening important? Most AAAs are "silent" until they rupture and AAA ruptures are often fatal.. The Mayo Clinic defines an AAA as "An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the bodys main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding". Screening for an AAA is an easy procedure - its simply an ultrasound of your abdomen, concentrating on the aorta. Canada Diagnostic Centres has been providing AAA screening since 2007 and patients often combine this screening test with our other screening exams for early detection of disease.. What ...
Abdominal Aortic Aneurism is a condition when large blood vessels responsible for supplying blood to the abdomen, legs and pelvis become unusually large or inflates in an outward direction. Aneurism has been particularly categorized into three groups, viz. genetically inherited diseases, enzyme destruction, and lifestyle-influenced conditions.The risk factors of an abdominal aortic aneurism include smoking, obesity, high cholesterol, high blood pressure, emphysema and genetic factors. It generally develops in males over the age of 60 experiencing any of these risk factors. The symptoms mostly include severe abdomen or back pain, nausea, vomiting, clammy skin, rapid heart rate and shock.. ...
Hey, guys and gals, another thing you need to be vigilant for is an abdominal aortic aneurysm. Though anyone can get them, they seem to be more prevalent in men than women and are a leading cause of death in older men. An abdominal aortic aneurysm, or AAA, is a weak spot in an artery wall in the stomach and can be hereditary and is also more common in smokers. You can and should get a screening to make sure youre not going to have one of these. Should something be found, modern medicine has a much easier way of treating it now than in the past. Nowadays, this can be repaired under local anesthetic (if you have the stomach for it!) and only takes about five days for recovery. ...

Having any type of surgery can cause you to worry, but needing surgery for an Abdominal Aortic Aneurysm (AAA) can bring on a whole new level of stress. The first thing to understand is that an open repair for an AAA is only performed when your vascular surgeon deems that the risk of rupture is greater than the risk of the surgery itself. If you are facing an upcoming open repair for an abdominal aortic aneurysm, keep reading to help you understand the procedure and why it may be necessary.. An abdominal aortic aneurysm (also known as a stomach aneurysm) results when the aorta becomes enlarged and/or begins to balloon out in the abdominal region. Not all aneurysms cause immediate, life-threatening situations; some develop over time without presenting symptoms for years. Any symptoms of constant pain in the abdominal region and/or back that spreads to the groin, fainting, nausea and vomiting, dizziness, racing heart, or clammy skin should be evaluated immediately. The purpose of open repair ...

Abdominal Aortic Aneurysm (AAA) Screening is now available in MPHC The 4th Practice in conjuction with Affidea. What is an AAA?. The aorta is the main vessel carrying blood around your body. In some people, especially older men, the wall of the aorta gradually weakens and starts to expand. See diagrammatic illustration below.. Is an AAA serious?. Large AAA are rare, but can be very serious. As the aorta expands it can burst, and the person usually dies. Small/medium sized AAA are not as dangerous, and your consultant vascular surgeon will arrange ultrasound monitoring to see if it gets bigger.. Is Screening for AAA important, and why are you invited?. Most people with AAA have no symptoms. A simple painless ultrasound scan of your tummy will tell if you have an AAA. We are inviting men only, as AAA are six times more common in men than women. Ruptured AAA mostly happens to men. You also are more likely to have an AAA if you you smoke, have high blood pressure or your parent, brother or sister ...
Yale University researchers have developed a way in which medical imaging with SPECT/CT could potentially be used to assess a patients rupture risk for abdominal aortic aneurysm. Delaying surgical treatment can be life-threatening, and this new type of imaging could allow physicians to diagnose disease and better plan its management. The study is presented in the featured article of the August issue of The Journal of Nuclear Medicine.

Background: Abdominal aortic aneurysm (AAA) is a common disease characterized by mobilization of inflammatory cells into vessel walls and activation of vascular cells, leading to degradation of extracellular matrix(ECM). CD44 is not only a principle receptor for hyaluronic acid (HA), but also an adhesion molecule expressed on inflammatory and vascular cells. Recently, we have reported that low-molecular weight HA induced inflammatory cytokines from human peripheral mononuclear cells. We investigated the potential role of CD44 in the development of AAA.. Methods: For induction of AAA, we applied 0.5 M CaCl2 to the infrarenal aortae of mice deficient for CD44, and wild type (WT) littermates as a control.. Results: Six week after application of CaCl2, the diameter of aorta in CD44−/−mice (12%±13%, n=8) was significantly smaller than that in WT mice (53%±12%, n=10). The elevated expression of matrix metalloproteinase (MMP)-2, -9, -12 and monocyte chemotactic protein-1 in WT aorta at one week ...

An abdominal aortic aneurysm (AAA) is a frequently asymptomatic ballooning of the aorta, which in case of rupture is terminal for the patient. Experiments on mechanical properties of AAA wall, investigations on biological processes measured by PET images, as well as FE simulations to determine in vivo wall stress were combined to clarify the so far poorly understood mechanobiology during AAA development. Mechanics-based indices were developed, which provide a reliable AAA rupture risk prediction. « ...
Im sure he must have inquired about the circumstances of my husbands death which I vaguely recall describing to him as I, too, was trying to make sense of it all. I think I told him of my husband having just seen his doctor the previous morning for a follow-up visit. For the prior two to three years, my husband had periodically undergone various tests to determine whether or not he had a small abdominal aortic aneurysm. Sometimes the aneurysm appeared to be present, sometimes not, but the medical action plan had been to track the small bulge for any increase in size. Tracking had been an ongoing problem since the bulge often was hidden from view during ultrasounds. The definitive angiogram or MRI (Magnetic Resonance Imaging) tests could not be administered since he had other serious medical problems making either test unsafe for him ...
Hemodynamic alterations occur when the elephant trunk (ET) technique is adopted to treat extensive aortic aneurysms. In planning the 2nd stage operation to complete ET repair, surgeons must weigh an adequate recovery time after initial surgery against the risk of postoperative ET-related complications. The purpose of this study was to understand the mechanistic link between the flow alteration caused by the ET graft and the development of premature aortic rupture before the 2nd stage operation. Specifically, fluid-structure interaction (FSI) analysis was performed using the CT imaging data of aorta at different stages of ET repair, and then computational variables were compared to those observed in patients who underwent a prophylactic 2nd stage operation to complete aortic repair ...

Abdominal aortic aneurysm, also written as AAA and often pronounced triple-A, is caused by a weakened area in the main vessel that supplies blood from the heart to the rest of the body. When blood flows through the aorta (blood vessel that delivers oxygen-rich blood from the left ventricle to the body; it is the largest blood vessel in the body.), the pressure of the blood beats against the weakened wall, which then bulges like a balloon. If the balloon grows large enough, there is a danger that it will burst. And, if the aneurysm ruptures, most patients die before reaching a hospital ...

Abdominal aortic aneurysm repair has undergone a revolution since Volodos and Parodi described endoluminal repair in the early 1990s. Subsequent data from large registries have confirmed its efficacy. Randomised controlled trials have shown that although endoluminal repair may not be as cost effective as open repair, it can be performed with a lower mortality in patients fit for open repair. Some European countries (eg, Belgium) have taken the results of these trials to rationalise the number of hospitals able to do endovascular repair. The devices continue to improve and although most require open surgical access at present, in future percutaneous access will become the norm. This article reviews the current state of endoluminal aortic aneurysm repair in the infrarenal aorta. ...
ATLANTA--Researchers have found a link between dysregulated tryptophan metabolism and abdominal aortic aneurysm, a life-threatening vascular disease, according to a new study led by Georgia State University.. Abdominal aortic aneurysm is a permanent, localized enlargement of the abdominal aorta, the largest artery in the abdomen that provides blood to the organs and tissues of the abdomen, pelvis and legs. Because the abdominal aorta is one of four sections of the aorta, the bodys main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding, according to the Mayo Clinic.. Abdominal aortic aneurysm occurs in up to 9 percent of adults older than 65 years of age, with about 15,000 deaths each year in the United States after rupture. Abdominal aortic aneurysms often grow slowly and without symptoms, making them difficult to detect.. There are no proven therapeutic strategies to block progression of the disease and rupture of the abdominal aorta. The only possible ...
The last decade has represented a time of fundamental change in the treatment of abdominal aortic aneurysms (AAAs). Potentially, vascular surgeons will either acquire catheter-based skills or relinquish the care for many patients with infrarenal AAA. We investigated AAA referral patterns and method of AAA repair after the establishment of an endovascular AAA program at our institution. We conducted a retrospective review of elective AAA repairs after the initiation of an endovascular AAA program in April 1994. Six vascular surgeons performed all procedures with a clear distinction between the surgeons (n=3) who performed traditional AAA repair only and those (n=3) who managed AAAs by means of either endovascular or traditional treatment. From April 1994 through December 2000, 740 elective AAA repairs were performed. During this time the mean number of AAA repairs has been 106/year ranging from 75 to 155/year. More notable however is the steady increase in the percentage of endovascular AAA ...

PURPOSE: Traumatic rupture of the thoracic aorta secondary to blunt chest trauma is a life-threatening emergency and a common cause of death, usually following violent collisions. The objective of this retrospective report was to evaluate the efficacy of endovascular treatment of thoracic aortic disruptions with a single commercially available stent-graft.. METHODS: Nine men (mean age 29.5 years) were admitted to our institution between January 2003 and January 2006 due to blunt aortic trauma following violent motor vehicle collisions. Plain chest radiography, spiral computed tomography, aortography, and transesophageal echocardiography were used for diagnostic purposes in all cases. All patients were diagnosed with contained extramural thoracic aortic hematomas, secondary to aortic disruption. One patient was also diagnosed with a traumatic thoracic aortic dissection, secondary to blunt trauma. All subjects were poor surgical candidates, due to major injuries such as multiple bone fractures, ...

Primary Hypothesis: All-cause mortality will differ by 25% between Endovascular repair (EVR) and Open repair. Secondary Hypotheses: Procedure failure, short term (12-month) major morbidity, number of hospital days, health-related quality of life and other procedure-related abnormalities will differ between the two AAA repair strategies. Primary Outcomes: All-cause mortality. Interventions: Patients will be randomized to one of these repair strategies for the elective treatment of AAA: (a) Open repair or (b) Endovascular repair (using FDA-approved devices). Study Abstract: Aortic aneurysm is the tenth leading cause of death in older men; AAA accounts for the majority of these deaths (about 10,000 deaths per year in the United States). Since one in 22 Veterans over the age of 50 have AAA and one in 200 have AAA with diameter greater or equal to 5.0 cm (making them candidates for elective repair), AAA is a major disease in the VA population. Questions about the relative safety and effectiveness of ...

SCVS 2018 Abstracts: Statin Therapy is Associated with Higher Long-term, but not Perioperative Survival after Abdominal Aortic Aneurysm Repair
Emergency endovascular aneurysm repair (eEVAR) for ruptured abdominal aortic aneurysm (rAAA) must be carried out instantly. This requires firm logistics that include the ability to cross-clamp the aorta without delay. The present article focuses on the technique of balloon control of the aorta in eEVAR with aspects on indications as well as the organization of this type of vascular service. Transfemoral insertion of the occlusion balloon under local anesthesia is advocated and described. The use of dual balloons shortens the time of visceral ischemia without necessitating repeat declamping until the aneurysm has been completely excluded. Staged declamping upon completion is necessary just as in open repair. A "balloon test" is suggested to better identify those high risk patients with a rAAA who may benefit from endovascular rAAA repair.. ...
Several predisposing factors have been identified as increasing the likelihood of aneurysm formation. These include older age, male gender, systolic and diastolic hypertension, history of current or past cigarette smoking, and first-degree relatives with a history of AAA. After age 50 in men and age 60 in females, the risk of an aneurysm increases with each subsequent decade. Males are four times as likely as females to have aneurysms, and having a first-degree relative with AAA increases risk four times. Smoking is the most important amendable risk factor, influencing both the likelihood of developing an aneurysm and rate of growth acceleration.. Although ideally individuals would have been identified and managed before developing complications like rupture, more than half of patients presenting with rAAA have previously undiagnosed aneurysms and as many as 30% of patients with rAAA are initially misdiagnosed. It is reported that 25% to 50% of patients with the rAAA present with the classic ...
When trumpeter, Peter Cripps had a CT scan for a kidney stone it was discovered he also had an abdominal aortic aneurysm.. "Just before Christmas I had the most horrendous pain in my abdomen. I had a CT scan, which revealed I had a kidney stone. Thankfully, that was quite small but, more worryingly, the nurse told me I also had an abdominal aortic aneurysm. The surgeon came to see me straight away and recommended an open AAA operation which was done on January 16 2007. "Id had a four-way heart bypass four years earlier and five years before that a heart attack and I was convinced I was not going to make it. But the operation went really well and I was out of hospital a week later. "I felt weak and tired and I was quite insecure when I first got home.

Alternative treatments for abdominal aortic aneurysm - Are there effective natural treatments for abdominal aortic aneurysm? No. Basically, trying to prevent the AAA from rupturing or leaking. This can be done with surgery (open vs. Placed via blood vessel) or with medical management and follow-up. The most "natural" thing is to do nothing, but this has a much higher death rate than surgical repair or blood pressure control with meds. Avoiding stress, tobacco, etc. May help keep BP down when used in conjunction with meds.
To provide the most rigorous possible test of the utility of screening, we designed the trial as a population based study with the primary end point, mortality from abdominal aortic aneurysm, to be analysed on an intention to treat basis. We planned to have 90% power to detect and declare significant (two sided α = 0.05) a relative reduction of 50% in mortality among men invited for screening over five years from the start of screening. Using available pilot data, we estimated that the control group would need to contain about 20 000 men to experience 55 deaths from abdominal aortic aneurysm.3. Men were identified from an electronic copy of the electoral roll, enrolment to vote being compulsory for all Australian adults. The ideal target age range for screening is 65-74 years, but the electoral roll listed fewer than 40 000 men in this age group in the main metropolitan area of Perth (the capital city of Western Australia) and satellite towns. The addition of men aged 75-79 years increased the ...
en] Chronic rupture of abdominal aortic aneurysm (AAA) resulting in unusual clinical manifestations can occur if the resistance of structures surrounding the aorta is sufficient to contain hemorrhage. In this report, we describe five cases of chronic ruptured AAA in which the presenting feature was crural neuropathy. All patients were male with a mean age of 74 +/- 1.8 years. At the time of presentation, crural neuropathy had been ongoing for 3 to 9 weeks. In three cases, AAA was not initially suspected because an inadequate clinical examination was performed (not in the vascular surgery department) and because of the small diameter of the aorta in relation to the patients morphology. Two patients had one episode of hypotension that was wrongly attributed to vagal attack. Abdominal CT scanning was always diagnostic of chronic rupture. In two cases, rupture was associated with erosion of the body of one or more vertebrae and laboratory evidence of inflammation, i.e., increase in sedimentation ...

This study was designed to evaluate the optimal surgical treatment strategy for abdominal aortic aneurysm (AAA) coexisting with coronary artery disease (CAD). Twenty-six patients (21 men and 5 women with a mean age of 72.6 }3.7years old) who required surgical treatment of both conditions were examined. Eleven patients underwent a one-stage operation. Four of them had on-pump CABG and 7, including 3 high-risk-patients, underwent off-pump CABG. There were no operative mortalities, but 3 patients had severe morbidity (respiratory failure, acute renal failure, pneumonia). Fifteen patients underwent a two-stage operation. None of them had rupture of the AAA during the interval between the two operations, but 2 patients with large AAA (more than 6cm in diameter) required emergency operation due to impending rupture of the AAA. There was no operative mortality, but one patient suffered acute renal failure. One-stage operation for low-risk patients seems to be a safe and reasonable strategy. One-stage ...

Friedrichshafen Clinic in Germany offers top-end surgical treatment for abdominal aortic aneurism. The department of general, visceral and vascular surgery, guided by Prof. Dr. Thorsten Lehmann, uses a wide range of traditional and new methods for abdominal aneurism treatment: open surgery; endovascular therapy, laparoscopic surgery, endovascular implants etc.
Abdominal aortic aneurysm (AAA) is a degenerative weakening of the aortic wall, mainly affecting elderly men with a prevalence of 4.4-7.7 %. AAA is characterized by medial and adventitial inflammatory cell infiltration associated with vascular remodeling of the extracellular matrix proteins such as collagen and elastin and with phenotypic modulation and loss of vascular smooth muscle cells (VSMCs). Although much research has been performed, the precise cellular and molecular pathways behind these processes are still poorly understood. The overall aim of this thesis was to target signaling pathways that affect vascular remodeling of AAA to potentially identify novel strategies and drug candidates for future treatment of aneurysmal diseases. In order to develop our understanding of the pathophysiology of AAA, we used the angiotensin (Ang) II-induced AAA animal model and human biopsies taken at end-stage of disease to recapitulate key aspects of disease formation.. Innate immune receptors such as ...

Blood vessels are tubes that carry blood throughout your body. Arteries (red) carry oxygen-rich blood from the heart to the rest of your body. Blood vessels that carry blood back to your heart are called veins (blue). An abdominal aortic aneurysm occurs when a part of the largest artery in the body, the aorta, weakens and expands.. The aorta is the artery that carries blood directly from the heart. Blood then flows from the aorta into smaller arteries that supply the rest of the body. A healthy artery is smooth on the inside, which allows blood to flow easily. The part of the aorta that travels through the abdomen (stomach area) is called the abdominal aorta. Smaller arteries branch of the abdominal aorta to carry blood to organs in the abdomen. These include the renal arteries, which supply the kidneys. Lower down, the aorta divides into two iliac arteries, which supply blood to the legs.. The problem begins when the lining of the aorta is damaged or the aorta may become weakened due to certain ...
Currently, the only management options for AAA are surgical (open or endovascular) based on ongoing follow-up with imaging at regular intervals. Telmisartan is currently approved for use in the United States by the Food and Drug Administration for management of hypertension. If telmisartan is found to be effective in slowing the progression of abdominal aortic aneurysms, this would provide a new treatment option for patients with AAA disease ...

Several large-scale trials comparing EVAR to open surgery for AAA have been published. Short-term surveillance consistently shows better outcomes for EVAR in respect to mortality. Also, EVAR is milder on patients and better tolerated. However, a well known advantage for open repair of AAA is that it is durable. Less surveillance is needed for these patients in comparison to patients undergoing EVAR. This makes open repair a preferred option for younger, healthier patients who can withstand the procedure and are believed to have a long life expectancy.. The EVAR 1 trial was a prospective, randomized trial comparing EVAR to open repair of AAA in over 1200 patients. In 2010 long-term follow-up was reported (median of 6 years). As expected, peri-procedural mortality was greater with the open repair (6%) than in the endovascular repair (2.3%). These short-term benefits remained at 6 months, but disappeared within 4-6 years, a time at which aneurysm and total mortality curves converged for both ...

In this study, we provide a contemporary overview of clinical outcomes in patients with known MFS without prior aortic dissection. This represents one of the largest MFS studies to date using 3-dimensional imaging techniques. We found a type B aortic dissection rate of 9% during a median follow-up period of 6 years. Type B aortic dissections generally occurred in mildly dilated proximal descending aortas, especially in patients with prior prophylactic aortic surgery. From our data, we were able to develop a risk score to predict type B aortic dissection in patients with MFS, on the basis of history of prophylactic aortic root surgery and proximal descending aortic diameter.. The occurrence of type A aortic dissection has become a rare event in patients with known MFS in the era of aggressive prophylactic surgery. Although AoRR has improved life expectancy considerably, distal aortic disease may develop later in patients with MFS (14,15). Replacement of the aortic root or ascending aorta with a ...

  • Although the causal effect cannot be determined by the results of these observational studies, this alarming association raises the concern that taking fluoroquinolones may promote AAD formation or increase the risk of disease progression and rupture in patients with AAD," the researchers determined. (aboutlawsuits.com)
  • In this latest study, researchers conducted animal studies on mice, comparing the effects of Cipro on the aortas of mice who had been provided high fat diets and subcutaneous angiotensin II infusions to simulate high aortic aneurysm and dissection risks, with normal mice. (aboutlawsuits.com)
  • The FDA advises heath care providers to avoid prescribing fluoroquinolones to people with, or at increased risk for developing, an aortic aneurysm, including elderly people and those with peripheral atherosclerotic vascular diseases, high blood pressure (hypertension), or genetic conditions like Marfan syndrome or Ehlers-Danlos syndrome. (healthcentral.com)
  • If indicated, treatment with EVAR or open repair of the diseased aorta can limit the risk of of aortic rupture. (wikipedia.org)
  • An aortic aneurysm, due to the thinning of the aortic wall, increases the risk for aortic rupture and dissection, which is exactly what it sounds like: the wall tears open. (regenexx.com)
  • Those who are most at risk for aortic rupture or aneurysm include the elderly and patients who have high blood pressure or hypertension, peripheral vascular disease, or atherosclerotic heart disease. (regenexx.com)
  • Now, it seems quinolone antibiotic use can be added to the risk list for aortic rupture and aneurysm. (regenexx.com)
  • The risk didn't stop when use of the drug stopped as the most at-risk period to experience aortic aneurysm or rupture was within 60 days of starting the drug. (regenexx.com)
  • Furthermore, an aneurysm that has increased by greater than 0.5 cm is at increased risk of rupture and should prompt repair. (statpearls.com)
  • Aneurysm larger than 7 cm is at high risk of rupture. (radiopaedia.org)
  • According to the findings, there was no sign that Cipro increased the risk of aortic problems in so-called unchallenged mice. (aboutlawsuits.com)
  • Concerns about the risk of aortic dissection and aortic aneurysm with fluoroquinolones emerged in late 2015, following the publication of a report in the medical journal JAMA Internal Medicine , which found that current use of Levaquin, Avelox or other similar antibiotics was associated with a two-fold increased risk of suffering an aortic aneurysm or dissection injury . (aboutlawsuits.com)
  • However, over recent years several alternative rupture-risk indicators have been proposed. (ul.ie)
  • This brief review examines some of these new approaches to AAA rupture-risk assessment, from both numerical and experimental aspects and also what the future may hold for AAA rupture-risk. (ul.ie)
  • While numerically-predicted wall stress, finite element analysis rupture index (FEARI), rupture potential index (RPI), severity parameter (SP), and geometrical factors such as asymmetry have all been developed and show promise in possibly helping to predict AAA rupture-risk, validation of these tools remains a significant challenge. (ul.ie)
  • Therefore, should a biomechanics-based rupture-risk be implemented? (ul.ie)
  • There have been some significant steps, both numerically and experimentally, towards answering this and other questions relating to AAA rupture-risk prediction yet regardless of the efforts underway in several laboratories, the introduction of a numerically-predicted rupture-risk parameter into the clinicians' decision-making process may still be quite some time away.

  • So, the aortic injury mechanism or mechanisms remains in dispute. (sae.org)
  • This study is a staged investigation of the physical parameters and mechanisms of human aortic rupture. (sae.org)
  • The bleeding can be retroperitoneal or intraperitoneal, or the rupture can create an aortocaval or aortointestinal (between the aorta and intestine) fistula. (wikipedia.org)
  • 2) At present, this triad is known as Austrian syndrome, in honor of Robert Austrian, who described eight cases of pneumococcal endocarditis complicated by aortic valve rupture and associated with meningitis. (thefreedictionary.com)
  • At the junction of the aorta and the left ventricle is the aortic semilunar valve, which contains three cusps. (thefreedictionary.com)
  • Rupture results from either loss of wall strength to the point at which systemic pressure is greater than wall strength, or external destruction of the wall of the aorta, by a tumor or traumatic means. (wikipedia.org)
  • The development of an aneurysm is a complex interaction of biomechanical factors such as intraluminal pressure and wall sheer on atherosclerotic walls and biochemical and proteolytic influences resulting in changes in cellular composition of the aortic wall. (statpearls.com)
