Thoracic Aortic Aneurysm Resection

In the case of clinically diagnosed thoracic aortic aneurysm, surgery is required in principle. Treatment of diseases: thoracic aortic aneurysm Indication In the case of clinically diagnosed thoracic aortic aneurysm, surgery is required in principle. Preoperative preparation 1. Comprehensive examination of heart and lung function. 2. Aortic angiography and cardiovascular ultrasound examination. 3. Control lung infections. Surgical procedure Incision: Different incisions are used depending on the location, size, shape and nature of the aneurysm. (a) ascending aortic aneurysm resection (1) Free the tumor, and place a non-invasive arterial forceps at the base. (2) Resection of the aneurysm, double-layered continuous suture of the arterial incision. 2. Fusiform aneurysm resection (1) Establish extracorporeal circulation to block the ascending aorta. (2) Free aneurysm. (3) If the proximal end of the aneurysm is 3cm away from the aortic annulus, the artificial blood vessel transplantation can be performed immediately after the tumor is removed. (4) If the proximal end of the aneurysm is less than 3 cm from the aortic annulus and there is aortic valve disease, then the valved artificial blood vessel is applied. (B) bow aortic aneurysm resection 1. Establish extracorporeal circulation. 2. After the aorta and the three branches of the arch were blocked at both ends of the tumor, perfusion was performed. 3. Free aneurysm and resected, and reserve an artery sleeve below the opening of the brachiocephalic artery. 4. The artificial blood vessels are respectively matched with the aorta and brachial artery sleeves. 5. Stitch each anastomosis with a polyester sheet. (three) descending aortic aneurysm resection 1. After establishing extracorporeal circulation, the tumor is incised and the blood and blood clots in the tumor are exhausted. 2. The intercostal blood vessels in the cavity are opened and sewed one by one. 3. The artificial blood vessel is anastomosed to the end of the descending aorta, and then the tumor wall is wrapped around the artificial blood vessel for suture fixation.
