A systemic inflammatory response to a variety of clinical insults, characterized by two or more of the following conditions: (1) fever >38 degrees C or HYPOTHERMIA 90 beat/minute; (3) tachypnea >24 breaths/minute; (4) LEUKOCYTOSIS >12,000 cells/cubic mm or 10% immature forms. While usually related to infection, SIRS can also be associated with noninfectious insults such as TRAUMA; BURNS; or PANCREATITIS. If infection is involved, a patient with SIRS is said to have SEPSIS.
Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
The period following a surgical operation.
Diversion of the flow of blood from the entrance of the right atrium directly to the aorta (or femoral artery) via an oxygenator thus bypassing both the heart and lungs.
The splitting of the vessel wall in one or both (left and right) internal carotid arteries (CAROTID ARTERY, INTERNAL). Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation.

The outermost covering of organs, blood vessels, and other such structures in the body.

Serum triglyceride: a possible risk factor for ruptured abdominal aortic aneurysm. (1/3079)

BACKGROUND: We aimed to determine the relationship between ruptured abdominal aortic aneurysm (AAA) and serum concentrations of lipids and apolipoproteins. METHODS: A cohort of 21 520 men, aged 35-64 years, was recruited from men attending the British United Provident Association (BUPA) clinic in London for a routine medical examination in 1975-1982. Smoking habits, weight, height and blood pressure were recorded at entry. Lipids and apolipoproteins were measured in stored serum samples from the 30 men who subsequently died of ruptured AAA and 150 matched controls. RESULTS: Triglyceride was strongly related to risk of ruptured AAA. In univariate analyses the risk in men on the 90th centile of the distribution relative to the risk in men on the 10th (RO10-90) was 12 (95% confidence interval [CI] : 3.8-37) for triglyceride, 5.5 (95% CI: 1.8-17) for apolipoprotein B (apoB) (the protein component of low density lipoprotein [LDL]), 0.15 (95% CI : 0.04-0.56) for apo A1 (the protein component of high density lipoprotein [HDL]), 3.7 (95% CI: 1.4-9.4) for body mass index and 3.0 (95% CI: 1.1-8.5) for systolic blood pressure. Lipoprotein (a) (Lp(a)) was not a significant risk factor (RO10-90 = 1.6, 95% CI: 0.6-3.0). In multivariate analysis triglyceride retained its strong association. CONCLUSION: Triglyceride appears to be a strong risk factor for ruptured AAA, although further studies are required to clarify this. If this and other associations are cause and effect, then changing the distribution of risk factors in the population (by many people stopping smoking and adopting a lower saturated fat diet and by lowering blood pressure) could achieve an important reduction in mortality from ruptured AAA.  (+info)

Ruptured abdominal aortic aneurysms: selecting patients for surgery. (2/3079)

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)

Incisional hernias in patients with aortic aneurysmal disease: the importance of suture technique. (3/3079)

OBJECTIVE: To study the rate of incisional hernia at 12 months in patients undergoing abdominal aortic aneurysm repair compared with others undergoing other surgery through midline incisions. METHODS: A prospective study of 1023 patients, 85 of these with aneurysmal disease. Wounds were continuously closed and the suture technique was monitored by the suture length to wound length ratio. RESULTS: Wound incisions were longer and operations lasted longer in aneurysm patients than in others. Incisional hernia was less common if closure was with a suture length to wound length ratio of at least four. Wounds were closed with a ratio of four or more in 39% (33 of 85) of aneurysm patients and in 59% (546 of 923) of others (p < 0.01). In aneurysm patients no wound dehiscence was recorded, the rate of wound infection was low and incisional hernia occurred in the same amount as in others. CONCLUSIONS: It is concluded that the rate of incisional hernia is similar in patients with abdominal aortic aneurysmal disease and others. Wounds are closed with a less meticulous suture technique in aneurysm patients.  (+info)

Is there a relationship between abdominal aortic aneurysms and alpha1-antitrypsin deficiency (PiZ)? (4/3079)

OBJECTIVE: To determine if the frequency of alpha 1AT deficiency (PiZ) is increased in patients with abdominal aortic aneurysm (AAA), and, to investigate whether aneurysmal stiffness and other clinical characteristics differ in AAA patients with and without alpha 1AT deficiency. METHODS: We identified alpha 1AT-deficient individuals by a monoclonal-antibody ELISA technique, in 102 consecutive patients with AAA. Positive ELISA samples were further phenotyped by isoelectric focusing to differentiate between the heterozygosity (PiZ) and homozygosity (PiZZ) state. Aneurysmal diameter and stiffness was measured using echotracking sonography and blood pressure measurements. RESULTS: The frequency of heterozygous alpha 1AT deficiency (PiZ) in patients with AAA was similar to that in the general population (6.8% and 4.7%, respectively, p > 0.3). The frequency of popliteal and femoral aneurysm was similar in male PiZ-carriers and non-carriers with AAA, as were age at diagnosis of AAA, aneurysmal diameter, aneurysmal stiffness, and presence of factors that may be associated with AAA (i.e. smoking, hypertension, diabetes mellitus, and family history of AAA). Occurrence of ischaemic heart disease was more frequent in male non-PiZ-carriers than in male PiZ-carriers with AAA (p = 0.03). CONCLUSIONS: The frequency of alpha 1AT deficiency (PiZ) was not increased in our series of patients with AAA and patients in whom the two disorders coexisted did not appear to have different clinical characteristics except for the lower occurrence of ischaemic heart disease among the PiZ-carriers.  (+info)

Repair of ruptured thoracoabdominal aortic aneurysm is worthwhile in selected cases. (5/3079)

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)

The value of late computed tomographic scanning in identification of vascular abnormalities after abdominal aortic aneurysm repair. (6/3079)

PURPOSE: The purpose of this study was to determine the prevalence of late arterial abnormalities after aortic aneurysm repair and thus to suggest a routine for postoperative radiologic follow-up examination and to establish reference criteria for endovascular repair. METHODS: Computed tomographic (CT) scan follow-up examination was obtained at 8 to 9 years after abdominal aortic aneurysm (AAA) repair on a cohort of patients enrolled in the Canadian Aneurysm Study. The original registry consisted of 680 patients who underwent repair of nonruptured AAA. When the request for CT scan follow-up examination was sent in 1994, 251 patients were alive and potentially available for CT scan follow-up examination and 94 patients agreed to undergo abdominal and thoracic CT scanning procedures. Each scan was interpreted independently by two vascular radiologists. RESULTS: For analysis, the aorta was divided into five defined segments and an aneurysm was defined as a more than 50% enlargement from the expected normal value as defined in the reporting standards for aneurysms. With this strict definition, 64.9% of patients had aneurysmal dilatation and the abnormality was considered as a possible indication for surgical repair in 13.8%. Of the 39 patients who underwent initial repair with a tube graft, 12 (30.8%) were found to have an iliac aneurysm and six of these aneurysms (15.4%) were of possible surgical significance. Graft dilatation was observed from the time of operation (median graft size of 18 mm) to a median size of 22 mm as measured by means of CT scanning at follow-up examination. Fluid or thrombus was seen around the graft in 28% of the cases, and bowel was believed to be intimately associated with the graft in 7%. CONCLUSION: Late follow-up CT scans after AAA repair often show vascular abnormalities. Most of these abnormalities are not clinically significant, but, in 13.8% of patients, the thoracic or abdominal aortic segment was aneurysmal and, in 15.4% of patients who underwent tube graft placement, one of the iliac arteries was significantly abnormal to warrant consideration for surgical repair. On the basis of these findings, a routine CT follow-up examination after 5 years is recommended. This study provides a population-based study for comparison with the results of endovascular repair.  (+info)

Suppression of experimental abdominal aortic aneurysms by systemic treatment with a hydroxamate-based matrix metalloproteinase inhibitor (RS 132908). (7/3079)

BACKGROUND: Abdominal aortic aneurysms (AAAs) are associated with chronic inflammation, disruption of medial elastin, and increased local production of elastolytic matrix metalloproteinases (MMPs). The purpose of this study was to investigate how treatment with a hydroxamate-based MMP antagonist (RS 132908) might affect the development of experimental AAAs. METHODS: Male Wistar rats underwent intraluminal perfusion of the abdominal aorta with 50 units of porcine pancreatic elastase followed by treatment for 14 days with RS 132908 (100 mg/kg/day subcutaneously; n = 8) or with vehicle alone (n = 6). The external aortic diameter (AD) was measured in millimeters before elastase perfusion and at death, with AAA defined as an increase in AD (DeltaAD) of at least 100%. Aortic wall elastin and collagen concentrations were measured with assays for desmosine and hydroxyproline, and fixed aortic tissues were examined by light microscopy. RESULTS: AAAs developed in all vehicle-treated rats, with a mean AD (+/- SE) that increased from 1.60 +/- 0.03 mm before perfusion to 5.98 +/- 1.02 mm on day 14 (DeltaAD = 276.4 +/- 67.7%). AAAs developed in only five of eight animals (62.5%) after MMP inhibition, with a mean AD that increased from 1.56 +/- 0.05 mm to 3.59 +/- 0.34 mm (DeltaAD = 128.1 +/- 18.7%; P <.05, vs vehicle). The overall inhibition of aortic dilatation attributable to RS 132908 was 53.6 +/- 6.8%. Aortic wall desmosine fell by 85.4% in the vehicle-treated rats (1210.6 +/- 87.8 pmol/sample to 176.7 +/- 33.4 pmol/sample; P <.05) but only by 65.6% in the animals treated with RS 312908 (416.2 +/- 120.5 pmol/sample). In contrast, hydroxyproline was not significantly affected by either elastase perfusion or drug treatment. Microscopic examination revealed the preservation of pericellular elastin and a greater degree of fibrocollagenous wall thickening after MMP inhibition, with no detectable difference in the extent of inflammation. CONCLUSIONS: Systemic MMP inhibition suppresses aneurysmal dilatation in the elastase-induced rodent model of AAA. Consistent with its direct inhibitory effect on various MMPs, RS 132908 promotes the preservation of aortic elastin and appears to enhance a profibrotic response within the aortic wall. Hydroxamate-based MMP antagonists may therefore be useful in the development of pharmacologic approaches to the suppression of AAAs.  (+info)

Infrarenal endoluminal bifurcated stent graft infected with Listeria monocytogenes. (8/3079)

Prosthetic graft infection as a result of Listeria monocytogenes is an extremely rare event that recently occurred in a 77-year-old man who underwent endoluminal stent grafting for infrarenal abdominal aortic aneurysm. The infected aortic endoluminal prosthesis was removed by means of en bloc resection of the aneurysm and contained endograft with in situ aortoiliac reconstruction. At the 10-month follow-up examination, the patient was well and had no signs of infection.  (+info)

We describe the case of a man who died of an abdominal aortic aneurysm rupture after an intravitreal injection of bevacizumab for neovascular age-related macular degeneration. A 74-year-old Korean man presented with visual disturbance in his right eye. He had previously been diagnosed with diabetes and hypertension, which were controlled with oral medications. We diagnosed him with neovascular age-related macular degeneration and he was treated by monthly intravitreal injection of bevacizumab for three months. Four days after his third intravitreal bevacizumab injection, he died of an abdominal aortic aneurysm rupture and uncontrolled bleeding. Abdominal aortic aneurysm rupture is highly lethal and there is a possible correlation with intravitreal injection of bevacizumab. Thus, we need to consider the risks of intravitreal bevacizumab injections for patients with abdominal aortic aneurysms.

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. ...
Abdominal aortic aneurysm is an aneurysmal dilatation of the abdominal aorta, usually defined as an aneurysm whose diameter increases by more than 50%. Abdominal aortic aneurysms are predominant in elderly males, with a male-to-female ratio of 10:3. Smoking significantly increases the risk of aneurysm rupture. Most abdominal aortic aneurysms are lesions below the renal artery level. Common causes include atherosclerosis, and other rare causes include cystic degeneration of the middle layer of the artery, syphilis, congenital dysplasia, trauma, infection, connective tissue disease, etc. Common risk factors for abdominal aortic aneurysm include smoking, hypertension, old age, male, etc. Most patients are asymptomatic and are often found by chance by physical examination for other reasons. A typical abdominal aortic aneurysm is an expansive mass pulsating laterally and anteroposterior. Half of the patients are accompanied by vascular murmurs. A few patients have symptoms of compression. Abdominal ...

N2 - Abdominal aortic aneurysms (AAAs) are a significant cause of morbidity and mortality worldwide whose incidence is increasing. Traditionally these aneurysms have been repaired by a standard surgical approach. Over the past decade, spurred by the development of endovascular therapies for a variety of vascular pathologies, the endoluminal treatment of AAAs has rapidly proliferated. Early stent-grafts used to treat AAAs were primarily home-made. Presently there are a number of industry-made devices available on both an investigational and approved for use basis and the number is growing. This review focuses on the types of stent-grafts currently available, indications for use and patient selection, as well as new patents issued over the years 1998 - 2000. The ideal stent-graft is yet to be developed and not all AAAs are amenable to ...
About 3 out of 4 abdominal aortic aneurysms dont cause symptoms. An aneurysm may be found by X-ray, computed tomography (CT or CAT) scan, or magnetic resonance imaging (MRI) that was done for other reasons. Since abdominal aneurysm may not have symptoms, its called the silent killer because it may rupture before being diagnosed. Pain is the most common symptom of an abdominal aortic aneurysm. The pain associated with an abdominal aortic aneurysm may be located in the abdomen, chest, lower back, or groin area. The pain may be severe or dull. Sudden, severe pain in the back or abdomen may mean the aneurysm is about to rupture. This is a life-threatening medical emergency. Abdominal aortic aneurysms may also cause a pulsing sensation, similar to a heartbeat, in the abdomen. The symptoms of an abdominal aortic aneurysm may look like other medical conditions or problems. Always see your doctor for a diagnosis. ...
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 ...

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 ...

Abdominal aortic aneurysm refers to abdominal aortic dilation of 3.0 cm or greater. The main risk factors are age older than 65 years, male sex, and smoking history. Other risk factors include a family history of abdominal aortic aneurysm, coronary artery disease, hypertension, peripheral artery disease, and previous myocardial infarction. Diagnosis may be made by physical examination, an incidental finding on imaging, or ultrasonography. The U.S. Preventive Services Task Force released updated recommendations for abdominal aortic aneurysm screening in 2014. Men 65 to 75 years of age with a history of smoking should undergo one-time screening with ultrasonography based on evidence that screening will improve abdominal aortic aneurysm-related mortality in this population. Men in this age group without a history of smoking may benefit if they have other risk factors (e.g., family history of abdominal aortic aneurysm, other vascular aneurysms, coronary artery disease).

OBJECTIVES: To study bowel ischaemia in transfemorally placed endoluminal grafting (TPEG) for abdominal aortic aneurysms, and any relation to cytokine response or postoperative fever. DESIGN: Prospective not randomised. University hospital setting. MATERIAL: Fourteen cases of conventional surgery and 23 cases of endovascular technique for infrarenal abdominal aortic aneurysm repair. METHODS: Tonometry was used for sigmoid colon pH, and ELISAs for serum IL-6. RESULTS: Mucosal pH in the sigmoid colon fell significantly during clamping and reperfusion in both groups. Lowest measured sigmoid colon pH was 7.10 in the open group, compared to 7.22 in the TPEG group (p , 0.05). The IL-6 levels in serum peaked after 4 h of reperfusion; 249 pg/ml in the open group, compared to 89 pg/ml in the TPEG group (p , 0.05). High levels of IL-6 in the postoperative period and persisting low sigmoidal pH were associated with serious complications. Postoperative temperature did not differ significantly between the ...
OBJECTIVE: The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach. METHODS: Clinical data on patients with ruptured abdominal aortic aneurysms treated at a single tertiary center in Brazil were prospectively recorded. The eligibility for endovascular treatment was evaluated by computed tomography scanning and anatomical features were determined based on the method of treatment. RESULTS: From February 2012 to January 2013 (12 months), 28 consecutive patients (mean age 67.2 years, range 45-85 years) underwent treatment for ruptured abdominal aortic aneurysms at our hospital. Eighteen patients (64.3%) were suitable for and underwent endovascular treatment with bifurcated endografts (16 patients) or aortouniiliac endografts (two patients). Ten patients who were considered unsuitable for endograft repair underwent open repair. Seven patients were ...

N2 - Background: The implications of intraluminal thrombus (ILT) in abdominal aortic aneurysm (AAA) are currently unclear. Previous studies have demonstrated that ILT provides a biomechanical advantage by decreasing wall stress, whereas other studies have associated ILT with aortic wall weakening. It is further unclear why some aneurysms rupture at much smaller diameters than others. In this study, we sought to explore the association between ILT and risk of AAA rupture, particularly in small aneurysms. Methods: Patients were retrospectively identified and categorized by maximum aneurysm diameter and rupture status: small (,60 mm) or large (≥60 mm) and ruptured (rAAA) ...
First generation aortic endovascular stent-grafts (EVG) had low applicability and were associated with a significant incidence of peri-procedural complications. With time, a number of EVG systems perished (some predictably) in a survival of the fittest. Improvements in design have been made as a result of these failures. Current designs have low peri-procedural morbidity and mortality and improving durability. This paper sets out to discuss the use of a variety of EVG for abdominal aortic aneurysm repair. The ideal properties of an EVG will be outlined along with some of the advantages and limitations of current, and, where appropriate, historical, commercially available stent-graft systems.. ...
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. But I tried to do a little more each day and was soon back on my feet. In fact, I was able to go back to my part-time job fitting insulation mats on yacht engines within just three weeks. I play trumpet in a band and was able to start blowing again ...
Results from the Lifeline dataset revealed a 30-day operative mortality rate for EVAR in this high-risk patient cohort of 2.9% compared to 5.1% for open repair. There was one AAA-related death in the interval from 30 days to one year in the EVAR group and none in open. The AAA-related death rate at one year was 3.0% for EVAR and 5.1% for open. Four additional AAA-related deaths occurred in the EVAR group, thus freedom from AAA-related death after EVAR was 97% at 30 days and 96% at four years by Kaplan-Meier analysis. After open repair, freedom from AAA-related death was 95% at 30 days and remained at that level to four years. The study found there was no significant difference in all-cause mortality between EVAR and open repair through the duration of this analysis. Four-year survival was 56% in EVAR and 66% in open repair. All-cause mortality at four years in the high-risk IDE patients was also compared with the normal-risk IDE patients. The high-risk EVAR mortality was twice that of the ...

Introduction: Endovascular aneurysm repair (EVAR) has been an established treatment for abdominal aortic aneurysm (AAA). Although statin use has been shown associated with better long-term survival following open AAA surgery, its impact on EVAR has not been systematically explored.. Methods: We retrospectively analyzed a multicenter database of 368 consecutive patients (age, 76 ± 8 years; 84% male) undergoing EVAR for AAA between November 2006 and December 2013. The outcome measure was overall survival following EVAR. Independent predictor associated with the outcome was assessed by Cox proportional hazard regression model. Furthermore, the association between the statin use and the outcome was assessed.. Results: During the follow-up of 30 ± 20 months, 38 patients died from cardiovascular disease (33%), cancer (23%) or infection (23%). Survival rate was 96% and 81% at 1 and 5 years, respectively. In Cox regression analysis, statin use (in 213 AAA patients, 58%) was negatively associated with ...
We thank Dr Han and colleagues, and Dr Murakami and colleagues, as well, for their interest in our study1 and for discussing our proposed pathomechanism of segmental aortic stiffness in the context of experimental and clinical aortic coarctation.. We read with great interest the report of an alternative rabbit model that combines external elastase application with proximal aortic coarctation to model accelerated abdominal aortic aneurysm development.2 Although poststenotic turbulent flow caused by experimental aortic constriction may critically contribute to aortic dilation in this model, aortic coarctation also results in segmental aortic stiffness and may therefore generate substantial axial wall stress during systolic aortic expansion that we believe is a critical driver of early abdominal aortic aneurysm development.. In our study, mild aortic infusion of porcine pancreatic elastase (1.5 U/mL for 5 minutes) was sufficient to induce initial elastin damage and aortic stiffening that eventually ...

We studied the use of carbon dioxide (CO 2) as a non-nephrotoxic contrast agent for EVAR. Methods: Recorded data from 114 consecutive patients who underwent EVAR with CO 2 as the contrast agent over 44 months were retrospectively analyzed. CO 2 was used exclusively in 72 patients and in an additional 42 patients iodinated contrast (IC) was given (mean, 37 mL). Renal and hypogastric artery localization and completion angiography were done with CO 2 in all patients, including additional arterial embolization in 16 cases. ...
An aortic aneurysm is a dilation of a segment of the aorta where the wall of the vessel becomes thin and weak. The most common site involves the abdominal aorta below the arteries to the kidneys. The main risk of an aortic aneurysm is rupture. If the aneurysm ruptures, the chance for survival is very low. If the aneurysm is repaired before rupture, the chance of survival is very good. In general, an abdominal aortic aneurysm should be repaired when it reaches a size of 5 centimeters in diameter. On average, an aortic aneurysm will increase in size 0.5 centimeters per year. A more rapid rate of enlargement might lead us to recommend repair before the aneurysm reaches 5 centimeters. There are currently two acceptable methods used to repair an abdominal aortic aneurysm. The most common method involves making an incision in the abdomen and directly exposing the aneurysm. The involved section of aorta is completely replaced with a prosthetic fabric tube. This operation is highly effective at reducing ...

If significant pressure is transmitted across percutaneously placed stem-grafts, they may prove unacceptable for abdominal aorta aneurysm repair. Therefore, we developed an in mm model to study transmission of pressure across various materials implanted in an aneurysmal lumen. A pinch roller model producing pulsatile flow through an aneurysm fashioned from heated polyethylene was used with H2O, glycerol and heparinized bovine blood. Continuous pressure readings obtained from 3 sites (above, below and mid aneurysm) were compared between different materials including bare ...

Abdominal aortic aneurysm (AAA) is a potentially fatal disease and survival rate is very low when rupture occurs. Experimental models related with abdominal aortic aneurysm are performed on intact and ruptured aneurysm (RAAA) models. By using AAA models; complex mechanisms of aneurysm formation, aneurysm progression, chance of rupture, preventative and treating methods are researched. Most commonly used methods for creating aneurysm are utilization of transgenic or knockout animals; intra/extraluminal pharmacologic treatments such as elastase, calcium chloride or angiotensin II; hyperlipidemic diet application and surgical interventions such as xenograft, stenosis or graft. Pathogenesis of aneurysm is predominantly examined on rodents whereas studies aimed at development of treatment modalities such as surgical or endovascular interventions are predominantly performed on large animals like rabbit, porcine or dog. Experimental studies modeling aneurysm rupture (RAAA) simulate shock (total hypoperfusion)
Endovascular abdominal aortic aneurysm (AAA) repair is surgery to repair a widened area in your aorta. Between 4% and 7% of men over 65 years of age have an AAA, but it is less common in women. If you have an Doctors usually recommend for specific methods to help in the recovery process of the patients. If the aneurysm does not grow much, you may live with a small aneurysm for years. Some institutions have longer lengths of stay. How long … The risk of complications is generally higher than with endovascular surgery, and the hospital stay and recovery time is often longer. The aneurysm is closed over the graft at the end of the operation to separate it from the overlying structures. Surgery for aortic aneurysm replacement may take 2 to 4 hours. How Do You Diagnose Coarctation Of The Aorta? An aneurysm means that the diameter is 1.5 times larger than normal, or 3 cm, in the abdominal aorta. We follow a strict editorial policy and we have a zero-tolerance policy regarding any level of ...
TY - JOUR. T1 - Endovascular management of abdominal aortic aneurysms. AU - Bush, R. L.. AU - Lin, P. H.. AU - Lumsden, Alan B.. PY - 2003/8/1. Y1 - 2003/8/1. N2 - An estimated 1.5 million people in the United States haves abdominal aortic aneurysms (AAAs) with more than 200 000 American diagnosed each year. The natural history of AAAs is to expand and rupture, accounting for an estimated 15 000 deaths per year. Thus, the major impetus for AAA repair is for prophylaxis against aneurysm-related death. The standard open surgical repair of AAAs is a well-established and durable procedure. However, as with all other major abdominal surgical operations, associated significant morbidity and mortality exist, along with prolonged recovery and various late complications. Furthermore, both mortality and morbidity increase significantly with advanced patient age and associated co-morbid disease states. Endovascular AAA repair using covered stent-grafts offers a significantly less invasive alternative to ...

The pathology of the human abdominal aortic aneurysm (AAA) and its relationship to the later complication of intraluminal thrombus (ILT) formation remains unclear. The hemodynamics in the diseased abdominal aorta are hypothesized to be a key contributor to the formation and growth of ILT. The objective of this investigation is to establish a reliable 3D flow visualization method with corresponding validation tests with high confidence in order to provide insight into the basic hemodynamic features for a better understanding of hemodynamics in AAA pathology and seek potential treatment for AAA diseases. A stereoscopic particle image velocity (PIV) experiment was conducted using transparent patient-specific experimental AAA models (with and without ILT) at three axial planes. Results show that before ILT formation, a 3D vortex was generated in the AAA phantom. This geometry-related vortex was not observed after the formation of ILT, indicating its possible role in the subsequent appearance of ILT ...
Thrombosis is closely linked to aneurysm evolution. In some cases, the presence of a clot can accelerate the time to aneurysm rupture while in others, it can stabilise the aneurysm and prevent rupture. The few computational models that simulate aneurysm thrombosis have focused on either cerebral aneurysms or on abdominal aortic aneurysms. The aim of these models has been to predict thrombosis outcome following intervention, or to better understand the processes at play during aneurysm thrombus formation. In this work, a joint thrombosis model which can be applied in both cerebral aneurysms and abdominal aortic aneurysms is proposed. It is thought that such an approach will be useful for elucidating clotting features which are common to both pathologies, and highlighting the key differences. This information will be useful for disease management and therapeutic approach. In my previous work, I have developed a computational model of thrombosis in cerebral aneurysms. In this work, I would like to ...

As part of the Oxford Abdominal Aortic Aneurysm (OxAAA) Study, we conducted an international survey of vascular surgery professionals. One aspect of the survey is as published in the International Journal of Cardiology: International Opinion on Priorities in Research for Small Abdominal Aortic Aneurysms and the Potential Path for Research to Impact Clinical Management. This Data-in-Brief article contains a detailed method for the conduct of this survey and additional original data. In this survey, we also provided vascular surgery colleagues with contemporary epidemiologic and surgical outcome data. This was followed by a hypothetical scenario whereby a patient had just been diagnosed with a small (40 mm) AAA and a novel biomarker predicted it to be fast growing in the coming years. We assessed the vascular professionals perception of the patients preference for management in this scenario, and their willingness to refer patients for a surgical trial that investigates the outcome of early versus
A new landmark study by researchers at the University of Maryland School of Medicine (UMSOM) found that patients with a vascular condition, called abdominal aortic aneurysm, received no benefits from taking a common antibiotic drug to reduce inflammation. Patients who took the antibiotic doxycycline experienced no reduction in the growth of their aneurysm over two years compared to those who took a placebo, according to the study published today in the Journal of the American Medical Association (JAMA). The finding could lead doctors to stop prescribing the drug as a way to prevent small aneurysms from growing larger and bursting.. This study provides strong evidence that doxycycline is of no benefit for patients with small abdominal aortic aneurysms in terms of preventing their growth. Health care providers should take note of the finding and stop using this as a prophylactic treatment, said corresponding author Michael Terrin, MDCM, MPH, Professor of Epidemiology and Public Health at UMSOM. ...
Management of ruptured abdominal aortic aneurysms. The latest evidence on the best way to manage a ruptured aneurysm will be presented including the one-year results of the IMPROVE trial and the IPD 3 trial. In the same session, the controversy as to whether many patients with ruptured abdominal aortic aneurysms are denied intervention will be discussed. Greenhalgh comments: Perhaps doctors are becoming more concerned about operating for fear of having poor mortality figures. We need to find evidence whether indeed patients are denied intervention.. Janet Powell (Imperial College, London, UK), member of the CX Programme Organising Board, considers that a few patients are offered repair of ruptured aortic aneurysm because perhaps not all centres have an endovascular team and facilities available at all times; additionally, there are financial stringencies on healthcare systems and many of these patients may need intervention out of hours. Holden adds that many questions on this subject remain ...
In many countries the gold standard for treating abdominal aortic aneurysms is still open surgery with a long incision. In patients with suitable anatomy alternatively an endovascular approach can be chosen. Since open surgery is more durable in many countries a laparoscopic procedure using key hole surgery has gained wider acceptance. The current study wants to prove that laparoscopic aortic aneurysm procedures are less invasive than open surgery with reduced recovery times.. Study design: Multi center prospective randomized study including patients with infra or juxtarenal aortic aneurysms ( AAA).. In group I the AAA is resected using a conventional long incision and standard procedures for resecting the AAA. A Dacron graft is used in inlay technique to restore blood flow.. In group II a total laparoscopic approach is chosen to exclude the AAA. Identical to open surgery a dacron graft is laparoscopically sawn in to exclude the AAA and to restore blood flow.. In a subgroup II a the ...

  • Blaivas M, Theodoro D. Frequency of incomplete abdominal aorta visualization by emergency department bedside ultrasound. (
  • An abdominal aortic aneurysm occurs when an area of the aorta becomes very large or balloons out. (
  • Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal. (
  • However, as the abdominal aorta expands and/or ruptures, the aneurysm may become painful and lead to pulsating sensations in the abdomen or pain in the chest, lower back, legs, or scrotum. (
  • The complications include rupture, peripheral embolization, acute aortic occlusion, and aortocaval (between the aorta and inferior vena cava) or aortoduodenal (between the aorta and the duodenum) fistulae. (
  • An abdominal aortic aneurysm occurs when the aorta becomes enlarged and balloons out. (
  • An abdominal aortic aneurysm (AAA) is a blood-filled bulge or ballooning in a part of your aorta that runs through your abdomen. (
  • The images produced by these methods help your doctor "see" inside your aorta as well as other blood vessels and organs in your body to see if an aortic aneurysm is present. (
  • As some people get older, the wall of the aorta in the stomach weakens and expands to form an abdominal aortic aneurysm. (
  • Screening can detect an aneurysm by the width of the aorta. (
  • Bilateral access starter guidewires are advanced under fluoroscopic guidance across the lesion in the abdominal aorta. (
  • An intravascular ultrasound (IVUS) catheter is advanced over the stiff guidewire for inspection of the abdominal aorta. (
  • The use of IVUS allows the surgeon to interrogate the entire abdominal aorta and the iliac vessels and to map out (on the fluoroscopic screen) the renal and internal iliac arteries without the use of contrast/fluoroscopy. (
  • The pigtail catheter is used to perform an aortogram of the abdominal aorta and the iliac arteries. (
  • An abdominal aortic aneurysm (AAA) is a weakening in the wall of the infrarenal aorta that results in an anteroposterior diameter of 3 cm or greater 1 . (
  • The abdominal aorta is most frequently affected. (
  • Four to five patients diagnosed with a ruptured abdominal aorta are treated at the Ilm-Kreis-Kliniken every year. (
  • Endovascular aortic aneurysm repair fixes an aneurysm in your aorta. (
  • The procedure is called endovascular because a doctor repairs the aneurysm from the inside of the damaged blood vessel (the aorta). (
  • An abdominal ultrasound reveals an aorta that's 5.6 cm in diameter. (
  • The surgeon she consults agrees and orders a computed tomography angiography (CTA) to confirm the size of the aorta, visualize retroperitoneal bleeding, and evaluate the location of the aneurysm and the renal arteries. (
  • Patients at poor risk for surgery may be candidates for endovascular aneurysm repair (EVAR), in which a stent is inserted into the portion of the dilated aorta to facilitate blood flow. (
  • Aneurysms that occur in the section of the aorta that runs through the abdomen (abdominal aorta) are called abdominal aortic aneurysms (ABDOMINAL AORTIC ANEURYSM). (
  • The portion of the aorta that lies deep inside the abdomen, right in front of the spine, is called the abdominal aorta. (
  • The pressure of blood pumping through the aorta may then cause this weak area to bulge outward, like a balloon (called an aneurysm). (
  • An ABDOMINAL AORTIC ANEURYSM occurs when this type of vessel weakening happens in the portion of the aorta that runs through the abdomen. (
  • As an aneurysm grows in size, the aorta wall becomes weaker and weaker, which means surgical intervention may be needed. (
  • Aortic dissection is a serious condition in which there is a tear in the wall of the major artery carrying blood out of the heart (aorta). (
  • Open abdominal aortic aneurysm (AAA) repair is surgery to fix a widened part in your aorta. (
  • An abdominal aortic aneurysm is an enlarged area in the lower part of the major vessel that supplies blood to the body (aorta). (
  • The aorta is the largest blood vessel in the body, so a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. (
  • An abdominal aortic aneurysm occurs when a lower portion of the body's main artery (aorta) becomes weakened and bulges. (
  • Aneurysms can develop anywhere along the aorta, but most aortic aneurysms occur in the part of the aorta that's in the belly area (abdomen). (
  • Smoking can weaken the walls of the aorta, increasing the risk of aortic aneurysm and aneurysm rupture. (
  • Having an aneurysm in another large blood vessel, such as the artery behind the knee or the aorta in the chest (thoracic aortic aneurysm), might increase the risk of an abdominal aortic aneurysm. (
  • Tears in one or more of the layers of the wall of the aorta (aortic dissection) or a ruptured aneurysm are the main complications. (
  • An abdominal aortic aneurysm (AAA) is a swelling of the aorta, the main artery in the body. (
  • Thus, enlargement of the diameter of the abdominal aorta to 3 cm or more fits the definition. (
  • Then, using an x ray to see the artery, the surgeon threads the graft (also called a stent graft) into the aorta to the aneurysm. (
  • The graft reinforces the weakened section of the aorta to prevent the aneurysm from rupturing. (
  • The catheter is threaded to the abdominal aorta, and the stent graft is released from the catheter. (
  • Abdominal aortic aneurysm (AAA) is a dilatation of the aorta as it passes through the abdomen. (
  • This is called an abdominal aortic aneurysm when bulging happens in the part of the aorta in abdomen region. (
  • Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. (
  • Most aortic aneurysms occur in the part of your aorta that's in your abdomen. (
  • Aneurysms can develop anywhere along the aorta, but when they occur in the upper part of the aorta, in the chest, they are called thoracic aortic aneurysms. (
  • More commonly, aneurysms form in the lower part of your aorta and are called abdominal aortic aneurysms. (
  • An aneurysm is usually defined as an outer aortic diameter over 3 cm (normal diameter of the aorta is around 2 cm), [4] or more than 50% of normal diameter. (
  • corresponds to a hyperattenuating peripheral area within the wall of the aorta or within a mural thrombus, indicating infiltration of blood from the lumen of the aneurysm into those structures, with consequent weakening of the wall of the aneurysm. (
  • An abdominal aortic aneurysm (AAA) (pathological enlargement of the aorta) is a condition that can occur as a person ages. (
  • Just below the level where the arteries to kidneys come off is a special segment of aorta which can expand as we grow older to form an aneurysm or dilatation of the main vessel. (
  • A 50% increase in the size of the vessel is the usual threshold for naming the aorta as having an aneurysm. (
  • So as the aneurysm gets bigger or the radius increases, the tension of the wall increases until the aorta ruptures. (
  • When aneurysms occur in the abdominal aorta which runs through the abdominal region, they are called abdominal aortic Aneurysms. (
  • The graft is first stitched on to the aorta with the walls of the aneurysm wrapped around the graft. (
  • A guide wire is inserted through small cut in the groin and threaded up the femoral artery and into the aorta, to reach the location of the aneurysm. (
  • An abdominal aortic aneurysm (AAA) refers to a swelling and weak spot in the aorta, the body's biggest blood vessel. (
  • An abdominal aortic aneurysm (AAA) is a blood-filled bulge or swelling, weak spot occurring in the aorta. (
  • Infection in the aorta, including bacterial or fungal infections, which rarely occurs but might cause aortic aneurysms. (
  • Having an aneurysm in another large blood vessel, like the artery behind the knee or the aorta in the chest, might heighten your risk of an abdominal aortic aneurysm. (
  • An aneurysm can be located anywhere along the abdominal aorta. (
  • The Abdominal Aorta is the main blood vessel that delivers blood to the body in the abdomen. (
  • Abnormal enlargement of the Abdominal Aorta can result in development of an Abdominal Aortic Aneurysm (AAA). (
  • A catheter is used to deliver the stent-graft to the abdominal aorta, where it seals off the aneurysm from the inside out. (
  • The average diameter of the abdominal aorta is approximately 2 cm (2.5 cm in thoracic aorta). (
  • 3 cm (1.5 times the normal diameter) is called an "aneurysm" We regard 5.0 cm (2.5 times the normal aorta) aorta diameter as the threshold for indication for surgery and increased risk of rupture. (
  • Unlike open surgery, where the artificial graft is directly sewn on the aortic tissue with sutures, the stent graft is anchored by a small hook or with friction forces due to oversized stent graft compared to the native aorta. (
  • The catheters help advance a wire and a stent-graft through the pelvic blood vessels towards the weak spot of the abdominal aorta. (
  • The abdominal aorta is a large artery, with a large volume of blood passing through it. (
  • Once the catheter is in place a stent is inserted and deployed in the abdominal aorta just below the level of the renal arteries. (
  • If the aneurysm is large or growing, we may perform an open surgical aneurysm repair to replace the weakened part of the aorta with an aortic graft. (
  • Abdominal aortic aneurysm (AAA) is a condition whereby the terminal aorta permanently dilates to dangerous proportions, risking rupture. (
  • We suggest that the maximum aneurysm diameter derived from CT imaging should be based on an outer wall to outer wall measurement perpendicular to the path of the aorta. (
  • How serious is an aneurysm in the aorta? (
  • An abdominal aortic aneurysm is when part of your aorta balloons with blood and ends up running through your abdomen. (
  • An aneurysm of the abdominal aorta (AAA) can be defined as an enlargement of the infra-renal aorta to a diameter of more than 29mm or 1.5 times the diameter of the aorta at the level of the renal arteries. (
  • The standard treatment for an AAA is a trans-abdominal open surgical approach and replacement of the aneurysmatic part of the aorta by prosthesis. (
  • A full median laparotomy is usually required to clamp the aorta above the aneurysm. (
  • In particular, de-clamping of the aorta at the level of the renal arteries after successful aneurysm repair is a considerable burden to the heart. (
  • Abdominal aortic aneurysm(AAA) is a common problem encountered which leads to dilation of the abdominal aorta. (
  • Aneurisma de aorta abdominal. (
  • Also known as AAA, an abdominal aortic aneurysm is a bulge in the aorta which could rupture with life-threatening results. (
  • An abdominal aortic aneurysm is the swelling or ballooning of the abdominal aorta. (
  • An aneurysm is a ballooning of the aorta which results from a weakened section in the artery that cannot support the force of blood flow (see Figure 2). (
  • Although an aneurysm can occur in any artery of the body, it is most common in the abdominal aorta and the iliac arteries. (
  • Figure 2 - An aneurysm is the ballooning of the abdominal aorta. (
  • Over time, the weakening of the aorta due to vascular disease, injury (trauma), or a genetic (hereditary) defect of the tissue within the arterial wall can cause an abdominal aortic aneurysm. (
  • With the use of special endovascular instruments, along with X-ray images for guidance, a stent graft will be inserted through the femoral artery and advanced up into the aorta to the site of the aneurysm. (
  • The stent graft is inserted into the aorta in a collapsed position and placed at the aneurysm site. (
  • A thoracic aortic aneurysm occurs in the body's largest artery (the aorta) that passes through the chest. (
  • Abdominal aortic aneurysms (AAA) occur when the aorta-the large blood vessel that delivers blood from the heart throughout to rest of the body-begins to bulge. (

  • Abdominal Aortic Aneurysm (AAA) is a localized enlargement of the abdominal aorta with a diameter greater than 3 cm or more than 50% larger than usual. (
  • It occurs when atherosclerosis or plaque buildup causes the walls of the abdominal aorta to become weak and bulge outward like a balloon. (
  • The abdominal aorta has branches to the superior mesenteric arteries proximally, and below that both renal arteries, which also supply the adrenals (suprarenal). (
  • Severe atherosclerosis with plaque buildup and separation of the media from the endothelium, can migrate down the addominal aorta before frank rupture of an aneurysm. (

  • Patients with large AAAs (≥6.0 cm) have higher all-cause mortality, complication, and reintervention rates after EVAR than those with smaller aneurysms. (
  • On the basis of our data, EVAR should be considered even in high-risk patients with a maximal aortic diameter between 5.5 and 6.0 cm because surgical risk with aneurysm size above 6.0 cm will increase significantly. (
  • One novel way of treating AAA is using endovascular aortic repair (EVAR) where a polymer stent graft (SG) is used to redirect blood flow. (
  • The aim of this study was to evaluate incidence, potential risk factors and effects on stent-graft migration of proximal neck dilatation after endoluminal repair of abdominal aortic aneurysm (EVAR), and the role of ultrasound (US) in detecting neck enlargement. (
  • Proximal aortic neck enlargement occurs in up to 30% of patients after EVAR and represents the main risk factor for stent-graft migration. (
  • Although, endovascular aortic repair (EVAR) compared to open surgery repair is characterized by a reduced perioperative mortality, the reintervention incidence after EVAR is still higher than after open surgery repair. (
  • Although endovascular aortic repair (EVAR) is a safe, effective, and currently the most widely used AAA treatment method, there are still issues which need to be resolved to significantly improve this treatment (4). (
