We describe the regression of a 6.5 cm diameter abdominal aortic aneurysm in a 71-year-old patient within 1 year of aortic endograft placement. The aneurysm decreased in size to 4 cm at 3 months and was 3.3 cm at 8 months on duplex examination. By 1 year a spiral computed ...

Coronary artery disease and poor left ventricular function are the most important risk factors for morbidity and mortality in patients undergoing abdominal aortic aneurysm repair. Effective screening programmes and prior revascularization procedures (percutaneous translumincal coronary angiography and coronary artery bypass graft surgery) have helped to decrease the risk of cardiac-related ...

Repair of abdominal aortic aneurysms may require aortic occlusion above the renal arteries. Despite fears of renal, hepatic and intestinal ischemia, recent publications have suggested that when repair would be difficult or impossible with infrarenal aortic clamping, supraceliac clamping may not be associated with significantly increased morbidity. Between February 1985 ...

An eight-month-old male child presented with a nonpulsatile abdominal mass, which was detected during a routine follow-up examination.
