A kind of compound intraoperative stent system and using method thereof

Abstract

The invention provides a composite intraoperative stent system, comprising an anastomotic artificial blood vessel, a wire-controlled released left subclavian artery stent-graft vessel and a ball-expandable descending aorta stent-graft artificial vessel; the artificial blood vessel and The ball-expandable descending aortic stent-graft artificial blood vessel is connected, and the left subclavian artery stent-graft vessel is located at the junction of the artificial blood vessel and the ball-expandable descending aortic stent-graft artificial vessel, and the left subclavian artery is covered with The membrane stent blood vessel communicates with the artificial blood vessel and the artificial blood vessel of the ball-expandable descending aortic stent-graft; the artificial blood vessel of the ball-expandable descending aortic stent-graft is provided with a balloon. The invention can shorten operation time, reduce the influence of deep hypothermia and circulatory arrest on the blood coagulation function of patients, reduce the difficulty of blood vessel anatomy and anastomosis, and improve the success rate of operation.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a composite intraoperative stent system and its application method. Background technique [0002] Type I aortic dissection or ascending aorta and aortic arch aneurysm is still one of the most complicated and risky diseases in the field of cardiovascular surgery. The mortality rate of type I aortic dissection is extremely high. From the onset to the first 48 hours, the mortality rate increases by 1% for every additional hour. Without surgical treatment, the mortality rate within 3 months is as high as 99%. The mortality rate of ascending aorta and aortic arch aneurysm rupture is close to 100%. The current standard method for dealing with such diseases is Sun's surgery (ie aortic root + arch artificial vessel replacement + descending aortic elephant trunk implantation). [0003] At present, when patients with type I aortic dissection undergo Sun's surgery, deep hypothermic circu...

AI Technical Summary

Problems solved by technology

[0003] At present, when patients with type I aortic dissection undergo Sun's surgery, deep hypothermic circulatory arrest is required to replace the aortic arch and place elephant trunk stents in the descending aorta. The Sun's surgery takes a long time and requires high requirements for anatomy and anastomosis. In addition, deep hypothermic circulatory arrest has a great impact on the coagulation mechanism of patients, and postoperative patients often die due to anastomotic bleeding or wound bleeding
