Abstract:
In order to evaluate digital subtraction angiography(DSA) in the management of Endovascular Graft Exclusion (EVGE) for dissecting thoracic aortic aneurysms,the operation procedures and results in 32 cases of EVGE were retrospectively analysed. The stent grafts were sent to the segment where the tears were located through the incision on the common femoral artery. After the deployment, the tears were sealed. Intraoperatively, 100% of the tears were revealed by DSA, and 4 endoleaks were also detected and managed effectively. The value of DSA in preoperative evaluation, choice of operative procedure, intraoperative monitoring, success ratio evaluation, complication prevention and management was determined. It is concluded that DSA can monitor EVGE on real time and throughout the operation. It can meet the needs of measuring, locating, evaluating thoracic aortic aneurym and deciding its operation,as well as detecting and controlling its complications. Moreover, it provides a large visual field and operating space, and is a high valuable monitoring method for EVGE.
