The sequela of a long-standing PVT is cavernous formation of the portal vein, which represents bridging collaterals around the occlusion. Isolated splenic vein thrombosis can develop in tandem with a patent portal vein. However, it is unusual to have thrombosis of the inferior/superior mesenteric veins without involvement of the portal vein itself. Budd-Chiari syndrome is the blockage of a hepatic vein or of the hepatic part of the inferior vena cava.This form of thrombosis presents with abdominal pain, ascites and enlarged liver.Treatment varies between therapy and surgical intervention by the use of shunts.

The aim of this retrospective study was to describe risk factors, clinical presentation, complications, and treatment of portal vein thrombosis in a single center. Upper extremity deep vein thrombosis (UEDVT) accounts for approximately 5 to 10 percent of all cases of DVT with incidence increasing due to higher frequency of intravenous catheter use. 1 Veins considered to be "deep" classically have a corresponding named artery. In the upper extremity the deep veins include the paired radial veins, paired ulnar veins, paired brachial veins, axillary vein ...

INTRODUCTION. The portal vein is formed by the confluence of the splenic and superior mesenteric veins, which drain the spleen and small intestine, respectively ().Occlusion of the portal vein by thrombus (portal vein thrombosis [PVT]) typically occurs in patients with cirrhosis and/or prothrombotic disorders ().Patients with acute PVT have the sudden onset of portal venous occlusion due to ... The aim of this study was to describe our experience in children with portal vein thrombosis (PVT) from march, 1991 through june, 1997. The medical records of all the patients who underwent endoscopy for the evaluation of gastrointestinal bleeding or suspected portal hypertension were reviewed retrospectively. Cirrhosis is the most common cause of portal hypertension in western countries. All other causes included in so-called ‘noncirrhotic portal hypertension’, account for less than 10% of the cases. In other geographical areas schistosomiasis (Africa) and portal vein thrombosis (India) are leading causes of portal hypertension. Figure 1.
Principles of treatment Goals of treatment ACUTE PVT • To recanalize the obstructed veins, which will prevent intestinal infarction and portal hypertension • To treat or avoid infection • Recanalisation of the portal vein virtually never occurs without treatment 27. Portal hypertension is hypertension in the hepatic portal system – made up of the portal vein and its branches, that drain from most of the intestine to the liver. Portal hypertension is defined as a hepatic venous pressure gradient. Cirrhosis is the most common cause of portal hypertension; other, less frequent causes are therefore grouped as non-cirrhotic portal hypertension.
