Portal vein aneurysm: A rare but important vascular condition

Portal Vein Aneurysm

“…Should symptoms appear or the aneurysm increase during observation, surgical treatment is recommended. 13 In the absence of portal hypertension, an aneurysmography for the fusiform variants, or the resection of the aneurysm in cases of saccular dilation should be preferred. 14 In the presence of portal hypertension, the direct approach to the aneurysm is avoided due to the high risk of bleeding.…”

Thrombosis of a Superior Mesenteric Vein Aneurysm: Transarterial Thrombolysis and Transhepatic Aspiration Thrombectomy

“…An acquired origin is postulated in cases with portal hypertension or a history of necrotizing pancreatitis [10,14]. Conversely, the in utero diagnosis of a portal vein aneurysm [24] as well as the prevalence of portal vein aneurysms in livers without any sign of portal hypertension [25] support a congenital origin. Failed prenatal regression of the right primitive vitelline vein or inherent weakness of the vein wall are proposed etiologies in these patients [14,26].…”

Treatment by splenectomy of a portal vein aneurysm in hepatosplenic schistosomiasis

“…We reviewed the scientific literature indexed in MEDLINE and LILACS (Latin American and Caribbean literature on Health Sciences) and recorded all descriptions of portal vein aneurysms, which correspond to 53 medical articles since 1965, referring to almost 70 cases up to the present, including English and non-English articles 1,4,7,8,14,15,17,19,21,[23][24][25][26]29,30 Portal aneurysms can be caused by portal hypertension, but have never before been related to hepatosplenic schistosomiasis. We report the finding of an intrahepatic portal vein aneurysm in a patient with hepatosplenic schistosomiasis with a marked reduction in its dimensions after splenectomy.…”
