- W2910497632 abstract "Portal venous system aneurysms - is the term used for the description of aneurysms of portal vein, mesenterica superior and inferior veins, splenic vein and confluence of splenic and mesenterica superior veins. Portal venous system aneurysms consider as rather rare nosological form with various pathogenesis, clinical manifestations or lack of those. Their prevalence varies according to literature depending on the used diagnostics methods (0.6-4.3 for 1000 patients). Since 1953 to today in the analysis of the PubMed, Scopus and eLibrary databases about 480 cases of portal venous system aneurysms are revealed. Aneurysms are localized in extra hepatic part of portal vein most often. They can be isolated and be combined with other pathology. The accompanying pathology are cirrhosis and portal hypertension more often. The clinical picture can be absent or have nonspecific symptoms. Ultrasonography is a preferable method at primary inspection by the patient with suspicion on existence of portal venous system aneurysms. At some disputable or difficult cases, and also in the presence of complications and associated diseases of hepatopancreatobiliary area, performance of MSCT and/or MRI is expedient. Waiting tactics of treatment is the main in the absence of clinic and complications, and also at the small sizes of aneurysm. Dynamic ultrasonography is an effective method of supervision over a condition of aneurysm. Symptomatic aneurysm of portal venous system and progressive rapid growth of aneurysm are indications for surgery. The most widespread complications are thrombosis of a cavity of aneurysm and a gap." @default.
