OBJECTIVE To review the anatomical variations of the right lobe encountered in 40 living liver donors, describe the surgical management of these variations, and summarize the results of these procedures. SUMMARY BACKGROUND DATA Anatomical variability is the rule rather than the exception in liver and biliary surgery. To make effective use of liver segments from living donors for transplantati...

S pontaneous portosystemic shunt (PSS) from portal hypertension is associated with portal vein (PV) stasis and chronic hepatic encephalopathy (HE). Embolization of PSS is effective in select cases of refractory HE, but is relatively contraindicated in patients with portal vein thrombosis (PVT) (Table 1). This procedure redirects significant blood flow back through the PV and has been reported t...

Partial nodular transformation is a rare condition which effects the perihilar portion of the liver and may cause chronic portal hypertension. This case report describes an elderly women in whom the condition was confined to the caudate lobe, which had become greatly enlarged and, by external compression of th portal vein at the hilum of the liver, had caused portal vein thrombosis and subseque...

Splanchnic vein thrombosis (SVT) – including mesenteric, portal, splenic and supra-hepatic veins thrombosis – is an underdiagnosed disease, with heterogeneous clinical presentations and a non-negligible rate of incidental findings. The main risk factors include abdominal diseases or interventions (e.g. infections, cirrhosis, abdominal cancer or surgical procedures), haematological disorders (ma...

First introduced in 1992 like a method to replace a damaged hepatic artery during major hepatobiliary surgery, Portal Vein arterialization (PVA) is becoming now a method to rescue the grafts in the field of liver transplantation, when an arterial thrombosis occur, and there are no alternative ways to restore the arterial flow. Moreover there are a lot of experimental studies showing that PVA ha...

Isolated pancreatic tuberculosis (TB) remains a rarity despite the high incidence of tuberculosis in many of the African and Asian countries. Presentation as discrete pancreatic mass often masquerades as pancreatic neoplasm and diagnosis may require histology. Extra-hepatic portal hypertension due to splenic vein thrombosis complicating pancreatic TB has been reported in the literature. We repo...

essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the digital ...

Balloon-occluded retrograde transvenous obliteration (BRTO) has become a common and effective procedure for treating hepatic encephalopathy due to a portosystemic shunt related to cirrhosis of the liver. However, this method of treatment has rarely been reported in patients after liver transplantation. Here, we report the case of a 52-year-old patient who underwent living donor liver transplant...

BACKGROUND Portal vein thrombosis was considered a contraindication for liver transplantation in the past because of the high morbidity and mortality rates. Many advances made the results better. AIM Review the advances and surgical strategies for liver transplantation in presence of portal vein thrombosis. METHOD Survey of publications in Medline, Scielo and Lilacs databases. Headings cros...
