Splenic vein aneurysm—report of a lesion that progressively expanded

Abstract

A case of splenic vein aneurysm is reported. The patient was diagnosed as having a cirrhotic liver with portal hypertension. Computed tomography and angiography demonstrated a splenic vein aneurysm with saccular dilatation. The splenic vein aneurysm increased in size as the hepatic cirrhosis deteriorated; however, there were no complications such as rupture or thrombosis. To our knowledge this is the first report describing the development of a portal system aneurysm.

A Large Spontaneous Splenorenal Shunt in a Patient with Liver Cirrhosis and Uncomplicated Portal Hypertension

“…A similar case of progressively expanding splenic vein aneurysm with saccular dilation was reported inal angiography, such as conventional splenoportovenography, or digital indirect portography (with arterial in a patient with cirrhotic liver and portal hypertension [63]. Many cases of portal cavernoma compressing the injections of dilute contrast medium) which, as compared with conventional portography, offers many advantages biliary tract were also reported, revealed in some patients by esophageal varice ruptures [64].…”

A Rare Intrasplenic Varix in a Patient with Chronic Liver Disease and Portal Hypertension

“…14 Ohhira et al reported a case of splenic vein aneurysm that progressively expanded in a patient with cirrhotic liver, portal hypertension, and hepatocellular carcinoma. 15 Tolgonay described a case of splenomegaly and splenic vein aneurysm due to a systemic infection in a patient with leukemia and no associated chronic liver disease. 16 There are a few reports of splenic vein aneurysms in the puerperium; Parpaglioni et al reported a case of splenic vein aneurysm that had ruptured into the abdominal cavity producing retroperitoneal and intraperitoneal hemorrhage in the immediate postpartum period, which was managed surgically.…”

Splenic vein Aneurysm with Calcification of Splenic and Portal Veins

“…5 Splenic vein aneurysms constitute a minority of PVSAs, and the mechanisms by which they develop are unknown. However, aneurysms developing in veins that are similar in size to the splenic vein have been attributed to mechanical forces that disturb laminar blood flow.…”
