Description
Technical Field
The invention relates to the technical field of medical treatment, in particular to an intrahepatic portosystemic shunt bracket with automatically adjustable diameter.
Background
Transjugular intrahepatic portosystemic stent-graft (TIPSS). The principle is that a special interventional therapy apparatus is adopted, under the guidance of X-ray fluoroscopy, a jugular vein is accessed, an artificial shunt channel which is positioned between a hepatic vein and a main branch of a portal vein in the liver is established, and a metal inner support is used for maintaining the permanent smoothness of the artificial shunt channel, so that the aims of controlling and preventing esophageal and gastric fundus varices from cracking and bleeding after portal vein high pressure is reduced, and ascites absorption is promoted. The puncture portal vein branch is a technical difficulty of TIPS. The spatial relationship between the hepatic vein and the portal vein is complex, and the spatial relationship can be changed by the pathological changes of anatomical variation and hepatic cirrhosis, so that the portal vein puncture positioning is difficult. Thus, the normal anatomical relationships are understood first, and variations may exist. Preoperative ultrasound f, cun venous location and intraoperative ultrasound guided puncture are practical, noninvasive, economical and convenient methods. The optimal puncture position is the position with the branch distance of 1.5-2.0 cm from the right trunk of the portal vein, and the ideal shunting effect is difficult to achieve if the optimal puncture position is too close to the peripheral branch. Too close to the portal trunk is very likely to cause penetration and severe intra-abdominal bleeding.
The liver cirrhosis portal hypertension combined with upper gastrointestinal hemorrhage seriously threatens the life of a patient, the internal treatment effect is not ideal, the surgical operation wound is large, and the death rate is high. By adopting transjugular intrahepatic portosystemic shunt (TIPSS), the pressure of the portal vein can be effectively reduced, and the embolization treatment can be performed on varicose bleeding gastric coronary veins and gastric short veins, so that the wound is small, the curative effect is good, but the restenosis after the operation is an important factor restricting the wide application of the restenosis. The restenosis rate of a purely applied bare stent is high, inflammation stimulation caused by bile leakage can be reduced by applying a covered stent, the restenosis rate can be reduced to a certain extent, but the covered stent has high hardness, is easy to cause poor form of a shunt, and affects the long-term patency rate.
The poor stability that generally fixes of intrahepatic portosystemic shunt support among the prior art leads to droing between the reposition of redundant personnel easily or causes easily to exert great pressure to the blood vessel, leads to the installation failure easily, the while is not convenient for observe the male degree of depth between the reposition of redundant personnel among the prior art, leads to accident easily, secondly, can not adjust support diameter size according to hepatic venous pressure gradient, consequently need urgently to develop a intrahepatic portosystemic shunt support that the diameter can automatic adjustment.
