Extrahepatic portal vein aneurysm: two case reports of surgical intervention

Bi Jin et al. World J Gastroenterol. .

Abstract

We report two cases of extrahepatic portal vein aneurysm, and both of them underwent surgical intervention. The first case had a mild pain in right upper quadrant of the abdomen; the second had no obvious symptoms. Physical examination revealed nothing abnormal. Both of them were diagnosed by magnetic resonance imaging angiography (MRA). One of the aneurysms was located at the main portal vein, the other, at the confluence of the superior mesenteric vein and the splenic vein, and these two places are exactly the most common locations of the extrahepatic portal vein aneurysm reported in the literature (30.7% each site). The first case underwent aneurysmorrhaphy and the second case, aneurysm resection with splenectomy. Both of them recovered soon after the operation, and the symptom of the first case was greatly alleviated. During the follow-up of half a year, no complication and adverse effect of surgical intervention was found and the color Doppler ultrasonography revealed no recurrence of the aneurysmal dilation. We suggest that surgical intervention can alleviate the symptom of the extrahepatic portal vein aneurysm and prevent its complications effectively and safely for low risk patients.

A: MRA revealed a fusiform dilation of the portal vein, measuring 3.0 cm×3.8 cm in diameter. B: During the operation, the aneurysm was exposed. C: After the aneurysm was resected, the dimension of the portal vein was greatly reduced.

A: MRA revealed an aneurysmal dilation at the confluence of the splenic vein and the superior mesenteric vein. The maximal diameter of the aneurysm was 4 cm approximately. B: The aneurysm which measured about 3.0 cm×4.0 cm was exposed. C: The splenic aneurysm was resected.
