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). There is inconclusive evidence to

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.

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.

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 ...

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 ...

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 ...

Vianne Nsengiyumva conducted experimental investigations into the role of vitamin D on abdominal aortic aneurysms (AAA). Vitamin D supplementation to achieve optimal circulating levels slowed the growth of AAA. Findings from this thesis are supportive of clinical trials to examine regulating vitamin D levels in AAA patients.. ...
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 ...
