Splenic arterial aneurysms (SAA) are rare and are usually atherosclerotic and/or related to pregnancy. Because pregnancy is the most important predisposing factor, the strong predilection of SAA for women is not surprising. The authors report a case of SAA rupture in a man with chronic pancreatitis as the predisposing factor. A 56-year-old man with abdominal pain and hematemesis was resuscitated and underwent endoscopy, but he died 18 hours later of massive hematemesis before definitive surgery could be carried out. At autopsy, there was chronic pancreatitis with fibrous adhesions tethering the tail of the pancreas, spleen, and posterior wall of the stomach together. The SAA was indented into the posterior wall of the stomach, into which it had ruptured from without. He also had alcoholic cirrhosis but no esophageal varices or conventional gastric ulcers. Other important predisposing factors such as abdominal trauma, infective endocarditis, polyarteritis nodosa, and segmental medial arteriopathy were absent. Histologic examination confirmed the rupture of the SAA. The SAA had Monckeberg medial calcinosis but little evidence of atherosclerosis. The well-documented complications of acute and chronic pancreatitis include shock, abscess, pseudocyst formation, and duodenal obstruction. This report describes the rare complication of SAA rupture, which may be fatal. 相似文献
