A previously healthy 82-year-old man presented with a 3-month history of bilateral lower limb oedema. Abdominal examination revealed prominent abdominal veins extending to the thigh. A large pulsatile abdominal aortic aneurysm (AAA) was noted in the epigastrium. Bilateral pitting leg oedema was noted along with a bluish discoloration of the feet. Clinical diagnosis of IVC thrombosis secondary t...

CMAJ | SEPTEMBER 11, 2017 | VOLUME 189 | ISSUE 36 E1137 A n abdominal aortic aneurysm (AAA) results from a weakening in a section of the aortic wall in the abdomen, which bulges because of pressure from blood flow to form an aneurysm.1 The aneurysm may grow and eventually rupture, causing death from hemorrhage.1 It is estimated that each year, 20 000 Canadians receive a diagnosis of AAA, and th...

Abdominal aortic aneurysm (AAA) was first described in the second century by Antyllus, who surgically ligated the proximal and distal ends of the aneurysm. The modern treatment of AAA began with the first AAA replacement using a homograft in 1951. Since that time, the screening, diagnostic method, surveillance, and treatment of AAA have been very well studied and incorporated into a modern para...

To demonstrate the use of a commercially available branch stent graft system, designed to preserve the internal iliac artery (IIA) in common iliac artery (CIA) aneurysms (CIAA) in two patients, who had undergone previous abdominal aortic aneurysm (AAA) surgery.

Surgical management of abdominal aortic aneurysm (AAA) with concomitant malignancy remains controversial. Commercial availability of a stentgraft may change the treatment strategy for such patients. We present a case of AAA with concomitant colon cancer, in which two-stage surgery consisting of EVAR and subsequent laparoscopic colectomy was performed with an interval of six days. The patient's ...

Abdominal aortic aneurysm (AAA), defined as a localized dilatation of abdominal aorta, is a significant cause of morbidity and mortality in aging populations. AAA is a life-threatening disease mainly because of the high fatality rates associated with aneurysm rupture. Early detection of AAAs will provide patients an opportunity to receive medical therapy and undergo elective repair before aneur...

__________________________________________________________________________________________ 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...

Establishing an animal model of abdominal aortic aneurysm (AAA) is the key to study the pathogenesis and the pathophysiological features of AAAs. We investigated the effects of low-pressurized perfusion with different concentrations of elastase on aneurysm formation rate in the AAA model. Fifty male New Zealand white rabbits were randomly divided into A, B, C, D, and E groups. 10 μL of normal s...

BACKGROUND Many studies have been performed in order to model abdominal aortic aneurysm (AAA) in an experimental animal, most commonly in small laboratory animals. In our study, we tried to find the best AAA model in a pig by using various mechanical and enzymatic mechanisms. METHODS Twenty-two pigs were operated on. We combined 3 mechanisms of creating an AAA, using an intraluminal infusion ...

Helicobacter pylori is thought to be related to atherosclerosis and aneurysm development. We aimed to detect virulance factors of H. pylori and examine the potential etiopathogenetic relationship between aortic aneurysm and H. pylori, 58 abdominal aortic aneurysm (AAA) and 38 ascending aortic aneurysm (AsAA) cases and 57 Healty control group (HCG) were included. We investigated H. pylori IgG by...
