Application of aortic root forming process to Stanford A-type aortic dissection clinic surgical method

Abstract

The present invention provides an application of aortic root angioplasty in Stanford type A aortic dissection clinical procedures. During the clinical treatment of Stanford type A aortic dissection, the premise of not using new surgical materials and increasing the cost of surgery It can basically eliminate the proximal dissection cavity of the aortic root, avoid anastomotic bleeding, avoid the compression of the coronary arteries by the proximal dissection cavity of the aortic root, and effectively avoid long-term false lumen caused by the proximal aortic root. There is formation of pseudoaneurysm caused by proximal neoplasia of the aortic root or anastomotic stoma. Reduce the possibility of bleeding while avoiding complications caused by massive blood transfusion, shorten the operation time, improve the success rate of the operation, reduce the difficulty of Stanford type A aortic dissection, and facilitate the promotion of Stanford type A aortic dissection and popularity.

Description

technical field [0001] The present invention belongs to the medical field. In particular, it relates to the application of an aortic root forming method in the clinical operation of Stanford type A aortic dissection. Background technique [0002] Aortic dissection refers to the tearing of the aortic intima under the action of internal and external forces, and blood in the circulation enters between the intima and the media, causing it to peel off, forming aortic dissection, also known as aortic dissection aneurysm. The incidence rate of this disease is about 50-100 cases per 100,000 population per year, and the onset is usually acute. 65%-75% of patients die within 2 weeks from cardiovascular complications such as dissection rupture, cardiac tamponade, and arrhythmia. The incidence rate of men is higher than that of women, and the ratio of men to women is 2 to 3:1. More than 80% of patients with aortic dissection have hypertension, and many patients have cystic medial necro...

Problems solved by technology

[0005] The first method is simple and quick to operate, but after the bioglue is injected, the closed dissection of the adhesion is easy to recur, and at the same time, there may be aortic root dilatation and root aneurysm in the long-term after operation, which may require reoperation

The second method adopts the sandwich method of bovine pericardium slice-proximal aortic wall-bovine pericardium slice to strengthen the proximal aortic root, and the complications of anastomotic bleeding are reduced. Once bleeding is difficult to stop, this method does not completely close Root dissection, long-term postoperative aortic root dilatation, root aneurysm, and even the possibility of reoperation for dissection recurrence still exists

And because of the edema and brittle texture of the vessel wall tissue after aortic dissection, these two methods cannot avoid the complications of anastomotic bleeding, which may require pericardial slice embedding or right atrial shunt to stop bleeding, and postoperative pseudoarterial proximal aorta There are many complications such as aneurysm, coronary artery compression, and shunt leading to heart failure
