Bacillus Calmette-Guérin (BCG) is a live attenuated strain of Mycobacterium bovis that has been used as effective treatment for early-stage transitional carcinoma of the urinary bladder. We present a case of a 68 year old man who had an abdominal aortic aneurysm following BCG therapy for bladder cancer. Contrast enhanced computerized tomogram (CECT) of abdomen and pelvis revealed bilateral hypo...

A 67-year-old man was admitted with severe back pain and bilateral lower limb swelling. Enhanced computed tomography showed an infrarenal abdominal aortic aneurysm (92 × 75 mm(2)) and a short aortocaval fistula (7 mm). Immediately afterward, circulatory collapse occurred, and the patient was rushed to the operating theater. A much larger aortocaval fistula (22 × 35 mm(2)) than that demonstrated...

Parallel endografts were introduced as a way to expand endovascular repair of aneurysms involving branch vessels. However, endoleaks as a result of the gutters between the parallel endografts made this technique less favorable. The "eye of the tiger" technique was introduced to reduce the gutters between the parallel endografts proximally in the aorta. We report endovascular repair of infrarena...

INTRODUCTION Cardiovascular events are common in people with aortic aneurysms. Arterial calcification is a recognised predictor of cardiovascular outcomes in coronary artery disease. Whether calcification within abdominal and thoracic aneurysm walls is correlated with poor cardiovascular outcomes is not known. PATIENTS AND METHODS Calcium scores were derived from computed tomography (CT) scan...

OBJECTIVE To quantitatively compare aortic curvature and motion with resulting aneurysm location, direction of expansion, and pathophysiological features in experimental abdominal aortic aneurysms (AAAs). METHODS AND RESULTS MRI was performed at 4.7 T with the following parameters: (1) 3D acquisition for vessel geometry and (2) 2D cardiac-gated acquisition to quantify luminal motion. Male 24-...

Non-anastomotic graft rupture is a rare but critical complication after abdominal aortic aneurysm (AAA) repair. Therefore, identifying the rupture sites is important to perform endovascular stent grafting. A 78-year old man who had undergone Y-grafting for infrarenal AAA before 17 years was referred to our hospital with the complaints of abdominal pain. Computed tomography revealed acute pancre...

BACKGROUND AND AIMS Metalloproteinases (MMPs) are considered to be key enzymes in the pathogenesis of abdominal aortic aneurysms (AAA), with elevated levels in diseased aorta and in patient sera. Statins seem to exert an inhibitory effect on MMP activity in the aortic wall. No data exist on the effect of statins on serum activity of MMPs and inflammatory cytokines (interleukins, IL). METHODS ...

Abdominal aortic aneurysm (AAA) is a true aneurysm, meaning a localized dilation of the aorta caused by weakening of its wall, and involving all three layers (intima, media, and adventitia) of the arterial wall (Fig. 86-1). A false aneurysm, or pseudoaneurysm, is a collection of flowing blood that communicates with the arterial lumen but is not enclosed by the normal vessel wall; it is containe...
