BACKGROUND Abdominal aortic aneurysms requiring surgical intervention are generally treated by endovascular means. Such procedures are not always offered in rural hospitals, possibly leaving patients underserved. We reviewed our experience initiating an endoaortic surgery program. METHODS A surgeon in a rural centre was credentialed to perform endovascular aortic aneurysm repair through colla...
Endovascular repair of infrarenal abdominal aortic aneurysms (EVARs) has revolutionized the treatment of aortic aneurysms, with over half of elective abdominal aortic aneurysm repairs performed endoluminally each year. Since the first endografts were placed two decades ago, many changes have been made in graft design, operative technique, and management of complications. This paper summarizes m...
Aortic aneurysm and dissections account for 1% to 2% of all deaths in the Western countries, and the incidence of thoracic aortic aneurysm (TAA) is ≈10.4 per 100 000 personyears. Furthermore, because acute aortic dissections might be disguised as heart attacks, true incidence numbers could be significantly higher. Aortic aneurysms are categorized into 2 main groups depending on their location: ...
Elective aneurysmectomy and bypass grafting are now well established as the preferred methods of treatment for patients with symptomatic abdominal aortic aneurysms or abdominal aortic occlusive disease. Since these are late manifestations of generalized arteriosclerosis, it is not surprising that cardiac reserve is the major factor in determining operative survival. In an effort to define the m...
RATIONALE Abdominal aortic aneurysms constitute a degenerative process in the aortic wall. Both the miR-29 and miR-15 families have been implicated in regulating the vascular extracellular matrix. OBJECTIVE Our aim was to assess the effect of the miR-15 family on aortic aneurysm development. METHODS AND RESULTS Among the miR-15 family members, miR-195 was differentially expressed in aortas ...
BACKGROUND Opposing views have been published on the importance of ultrasound screening for abdominal aortic aneurysms. The Multicentre Aneurysm Screening Study was designed to assess whether or not such screening is beneficial. METHODS A population-based sample of men (n=67800) aged 65-74 years was enrolled, and each individual randomly allocated to either receive an invitation for an abdomi...
__________________________________________________________________________________________ Introduction: Abdominal aortic aneurysm is a localized widening, located below the renal arteries. The exact etiology is not fully understood. Probably the main role in the formation of abdominal aortic aneurysm plays a correlation between genetic and environmental factors, especially smoking. The disease...
Mycotic aneurysms constitute a small proportion of aortic aneurysms. Endovascular repair of mycotic aneurysms has been applied with good short-term and midterm results. However, the uncommon aortoenteric fistula formation remains a potentially fatal complication when repairing such infective aneurysms. We present the case of an 80-year-old woman with thoracic and abdominal aortic mycotic aneury...
Methods Since May 2010 51 patients with a median age of 69 years were included. Among them there were 32 (89%) men and 4 (11%) women. 28 (78%) patients had infrarenal localization of abdominal aortic aneurysms, 8 (22%) patients had juxtarenal localization of AAA. In 34 patients (94%) abdominal aortic aneurysms were etiologicaly atherosclerotic and in 2 patients (6%) it was Marfan syndrome to be...
RATIONALE Abdominal aortic aneurysms (AAAs) exhibit marked sexual dimorphism with higher prevalence in men. Similarly, AAAs induced by angiotensin II (AngII) infusion into mice exhibit a higher prevalence in males. Testosterone promotes AAA pathology in adult male mice through regulation of angiotensin type 1A receptors (AT1aR) in abdominal aortas. However, mechanisms for sexual dimorphism of r...
