ObjectiveTo assess the efficacy of endovascular treatment in Stanford B aortic dissection. Methods25 cases with type B aortic dissection were chose. After general anesthesia, the left brachial artery was punctured, then the mark catheter was inserted to the ascending aorta via the left brachial artery. The right femoral artery was separated through the right groin incision. Mark catheter was placed artery through puncture of right femoral artery catheter and confirmed in true lumen. A super-hard guidewire was placed to the ascending aorta through mark catheter. Blood pressure was controlled after the whole body heparinization. Among the 25 cases, there were 4 cases who were gave emergency surgical operation. The others were gave limited operation after the acute phase. Results25 aorta stents and 6 common vessel stents were implanted in 25 patients. Among them, 6 cases received left subclavian artery chimney stent implantation, 5 cases were given left vertebral artery-artificial blood vessel-left common carotid artery bypass grafting. 5 patients occurred leakage after stent implantation, then were given balloon dilatation. Postoperative complications were found in 5 cases. There was no death. ConclusionEndovascular treatment is an effective and relative safety method for the treatment of type B aortic dissection.
