The efferent vessel of hepatocellular carcinoma (HCC) and the mechanism and pathogenesis of the high frequency of intrahepatic metastasis in HCC has not yet been clarified. Three hundred ninety-three resected specimens of HCC were examined for tumor thrombosis in the portal vein and the hepatic vein: 231 tumors < or = 5 cm in diameter were examined for the relationship between mode of tumor spr...

In the last ten years new techniques, such as percutaneous ethanol injection (PEI) and radiofrequency ablation (RFA), have been developed for the treatment of hepatocellular carcinoma (HCC). Portal vein involvement is a complication of HCC and the role of surgical resection for HCC with tumor thrombi in the portal veins is controversial. Here we present the case of a 58-year-old man, with Child...

Pathophysiology Portal vein obstruction can result from one or several of the following 3 mechanisms: thrombosis, invasion by a malignant tumor (mainly hepatocellular carcinoma) and constriction within a malignant tumor (adenocarcinoma of the pancreas or bile ducts). Compression in the absence of thrombosis, invasion or constriction does not produce portal vein obstruction. Usually, the vein pa...

BACKGROUND Pancreatic metastases from previously treated renal cell carcinoma are uncommon. Surgical resection of pancreatic metastasis remains the only worthwhile modality of treatment. CASE PRESENTATION A case where pancreatic metastasis from previously resected right sided renal cell carcinoma was resected with a subtotal left pancreatectomy is described. An unusual feature was the presenc...

Gallbladder varices are a rare form of collateralization that develop in patients with portal hypertension. We present here a case of gallbladder varices accurately diagnosed by contrast enhanced CT imaging of the abdomen and confirmed by Color Doppler Sonography. A 76-year-old patient with hepatocellular carcinoma developed portal vein thrombosis due to tumor extension during the course of tre...

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...

conclusions in our study, portal venous thrombosis was detected in the patient who died during the acute period only. a study including large numbers of budd-chiari-syndrome patients with behcet’s disease and portal venous thrombosis would be helpful to determine the prognostic significance of portal venous thrombosis in budd-chiari-syndrome patients with behcet’s disease. in addition, patients...

The accumulation of chyle in the peritoneum appears when a disruption of the lymphatic system occur. The origin of this disruption may be secondary to traumatic injury, the exudation of lymph through retroperitoneal vessels or to obstruction or rupture of the peritoneal or retroperitoneal lymphatic glands. In this way, portal vein thrombosis is an unusual cause of chyloperitoneum. The etiology ...
