Abstract

A recoverable transjugular portosystemic shunt thrombolysis catheter is provided. The recoverable transjugular portosystemic shunt thrombolysis catheter comprises a conduit segment and a draw segment;it is characterized in that the conduit segment comprises a portal vein part, a connecting part and a liver vein part; the connecting part connects the portal vein part and the liver vein part; the draw segment is connected with the liver vein part; the draw segment is a solid segment; during usage, the draw segment is fixed after extending out from the portal vein to the jugular vein and then extending to the outside or extending to a subclavian vein or an upper arm vein to be fixed in an infraclavicular region or the upper arm vein; during usage, the portal vein part is arranged in the portal vein; the liver vein part is arranged in the liver vein; besides, the portal vein part and the liver vein part are arranged as mesh structures; the connecting part is a structure does not include meshes. After the conduit is imbedded and thrombus in portal vein is removed, the thrombus can be taken out by the draw segment; the purpose of the setting of the draw segment solid is to ensure that blood flow through the portal vein into the inferior vena cava after passing through the hepatic vein, but not into the liver parenchyma or in vitro through the draw segment.

Description

technical field [0001] The invention belongs to medical devices in the field of interventional radiation, in particular to an improved device for a portal systemic shunt thrombolysis catheter, in particular to a recoverable transjugular portosystemic shunt thrombolysis catheter. Background technique [0002] Portal vein thrombosis (PT) refers to a thrombus that occurs in the main portal vein, superior mesenteric vein, inferior mesenteric vein, or splenic vein. Portal vein thrombosis can cause portal vein obstruction, resulting in increased portal pressure and intestinal congestion, which is an important cause of prehepatic portal hypertension. Portal vein thrombosis is mostly secondary to chronic liver disease and tumor disease. Simple extrahepatic portal vein obstruction is more common in adolescents and children. Treatment methods for portal vein thrombosis include 1. Anticoagulant therapy 2. Thrombolytic therapy 3. Interventional minimally invasive and traditional surgi...
