Abstract:
The purpose of this study was to evaluate the prothesis and vascular features of Debakey III aortic dissection by DSCT angiography after endovascular graft exclusion. We performed a retrospective analysis of 39 Debakey III aortic dissection patients who underwent DSCT angiography after endovascular graft exclusion. After the operations in this study, all the 39 patients had no stent fracture and migration, 15 among all the 39 had endoleaks (type I 12 patients, type II 2 patients, 1 patient had no reason), 17 had large amount of thrombosis in false lumen, and 1 had false lumen outside the stent absorbed completely. While before the operations, 15 patients had abnormal renal perfusion pre-operation, and 9 of them had recovered after the operations. And the nearer located to the initial exclusive place, the more obviously the aortic remodeling occurred. In conclusion, DSCT angiography can accurately evaluate the prosthesis and anatomic-pathologic features of Debakey III aortic dissection after endovascular graft exclusion.
