RESUMO
Extra-hepatic portal vein obstruction (EHPVO) is an important cause of non-cirrhotic portal hypertension, in Third World countries like India. In this disorder, it results in obstruction and cavernomatous transformation of portal vein with or without the involvement of intra-hepatic portal vein, splenic vein, or superior mesenteric vein resulting in portal hypertension and esophagogastric varices. Extensive collateral circulation develops, involving paracholecystic, paracholedochal and pancreaticoduodenal veins which results in formation of ectopic varices, and portal biliopathy. Besides variceal bleeding, patients may have symptoms of portal biliopathy, hypersplenism, and growth retardation. Although the liver may appear normal, functional compromise develops in the long term. Patients with extra-hepatic portal vein obstruction are usually young and belong to India and other Asian countries. The variceal bleeding in EHPVO can be managed by endoscopic obliteration of varices, or by portosystemic shunt surgery. In this case report, we present a case of 15 year old male, with extra-hepatic portal vein obstruction due to combined deficiency of Protein C and Protein S recanalized by short-term low molecular heparin plus oral Rivaroxaban therapy
RESUMO
Protein-C and Protein-S deficiency states are responsible for 3-5% (Protein-C) and 2-3% (Protein-S) of patients with venous thrombosis. Some cases of arterial thrombosis have been reported. It occurs twice as often in female as in males. A 50 years old lady presented with acute severe pain in the left upper limb for 2 days. On investigation she was diagnosed as a case of bracheal artery thrombosis with Protein-C & Protein-S deficiency. Bracheal thromboembolectomy was done and discharge her with life long warfarin therapy. In one year follow up the patient had no untoward event and INR done every month and warfarin is adjusted.
