We present a case of a 53-year-old man with complaints of severe abdominal pain and nausea. Emergency department abdominal workup was non-diagnostic. Physical examination revealed signs of right- and left-heart failure. A past medical history of dysrhythmias and chronic abdominal complaints prompted hospital admission. Subsequent right heart catheterization revealed a ...

Prompt diagnosis of rupture and impending rupture of abdominal aortic aneurysms is imperative. The computed tomographic (CT) findings of ruptured abdominal aortic aneurysms are often straightforward. Most ruptures are manifested as a retroperitoneal hematoma accompanied by an abdominal aortic aneurysm. Periaortic blood may extend into the perirenal space, the pararenal ...

The major disease processes affecting the aorta are aortic aneurysms and dissections. Aneurysms are usually described in terms of their anatomic location, with thoracic aortic aneurysms (TAAs) involving the ascending and descending aorta in the thoracic cavity and abdominal aortic aneurysms (AAAs) involving the infrarenal abdominal aorta. Both thoracic and ...

Visceral artery aneurysms (VAA) represent 0.1-0.2% of all vascular aneurysms. For VAA's etiology, congenital or arteriosclerotic factors, media defects, infections, vasculitis and trauma are discussed. Ultrasound, CT scan and magnetic resonance imaging underline the diagnosis of VAA. The low perioperative morbidity and mortality and the excellent surgical longterm results justify ...

Gastrointestinal bleeding can be caused by a variety of pathologies. Primary aortoappendicular fistula is rare and, in our case, arose in addition to a chronic contained rupture sac of an abdominal aortic aneurysm. Clinical diagnosis is difficult. Aortic aneurysmorrhaphy along with extensive debridement and emphasis on antibiotic therapy is curative.

Chronic transmural inflammation and proteolytic destruction of medial elastin are key mechanisms in the development of abdominal aortic aneurysms (AAAs). Diferuloylmethane (curcumin) is a major component of the food additive tumeric, which has been shown to have anti-inflammatory properties. To determine if ingestion of curcumin influences aneurysmal degeneration, C57Bl/6 mice ...
