Abdominal pain caused by thrombosis of a gastroepiploic artery aneurysm--a case report.

Symptomatic visceral aneurysms usually present with abdominal pain and shock, gastrointestinal bleeding, or hemobilia when the aneurysm ruptures. Less frequently, visceral aneurysms are found incidentally during abdominal computed tomography or angiography. Thrombosis is a frequent complication of popliteal and femoral aneurysms but is rarely seen with a visceral aneurysm. The author believes this is the first report of complete thrombosis of a gastroepiploic artery aneurysm. The patient, who was seen for abdominal pain, had a previously unrecognized aneurysm.
