“…Rupture of the biliary system can also occur, causing gastrointestinal bleeding. 3,6 In view of this, the great majority of physicians opt for conservative management, monitoring the patient with sequential imaging exams. In 2009, a systematic review was conducted of 93 reports published in the literature, describing a total of 176 patients with 198 visceral venous aneurysms.…”

“…2 They are most commonly seen in the extrahepatic region, at the confluence between the splenic and superior mesenteric veins, followed by the portal vein and its branches. 3 Barzilai and Kleckner 4 published the first report of a case of APV in 1956, describing and aneurysm of the portal vein with thrombosis in its interior that had ruptured into the biliary system, found during an autopsy on a cirrhotic patient. 4 Since then, around 200 cases of the condition have been described in the literature.…”

“…5 The physiopathogenesis of aneurysm formation has not yet been established, but two theories exist: the first is a congenital condition, resulting from a failure of the distal vitelline vein to completely regress or from weakness of the internal vein wall, while the second is an acquired condition, secondary to chronic liver disease, portal hypertension, trauma, pancreatitis or surgery. 3 It is believed that the increased intraluminal pressure observed in portal hypertension may cause dilation of the portal vein's relatively thin walls. However, some authors believe that there must be some other explanation in view of the low incidence of portal vein aneurysms among patients with portal hypertension.…”

Aneurysms and thromboses of the portal vein are rare pathologies of the portal system that commonly follow an asymptomatic course. The vast majority of cases are diagnosed as incidental findings during imaging studies. Symptoms of aneurysms are the result of mass effects, while thrombosis symptoms are a function of the liver's ability to form a collateral circulation network in the thrombosis. The scant experience with such cases poses a dilemma for patient management and so the vast majority of authors choose an expectant approach with rigorous patient surveillance and only intervene in symptomatic patients. We report one case of an aneurysm of the portal vein and one case of portal vein thrombosis and discuss management and observation of these patients.

Portal vein aneurysm is an unusual vascular dilatation of the portal vein, which was first described by Barzilai and Kleckner in 1956 and since then less than 200 cases have been reported. The aim of this article is to provide an overview of the international literature to better clarify various aspects of this rare nosological entity and provide clear evidence-based summary, when available, of the clinical and surgical management. A systematic literature search of the Pubmed database was performed for all articles related to portal vein aneurysm. All articles published from 1956 to 2014 were examined for a total of 96 reports, including 190 patients. Portal vein aneurysm is defined as a portal vein diameter exceeding 1.9 cm in cirrhotic patients and 1.5 cm in normal livers. It can be congenital or acquired and portal hypertension represents the main cause of the acquired version. Surgical indication is considered in case of rupture, thrombosis or symptomatic aneurysms. Aneurysmectomy and aneurysmorrhaphy are considered in patients with normal liver, while shunt procedures or liver transplantation are the treatment of choice in case of portal hypertension. Being such a rare vascular entity its management should be reserved to high-volume tertiary hepato-biliary centres.
