Hemolytic Anemia Caused by Kinking of Dacron Grafts Implanted in Repair of after Aortic Dissection

Abstract

BACKGROUND: Hemolytic anemia caused by a kinked Dacron graft is a rare complication after repairof acute aortic dissection. We present a case of hemolytic anemia due to kinking of previously implantedDacron graft for ascending aorta dissection treated by surgery and replaced with new Dacron.CASE DETAILS: We report a case of postoperative hemolytic anemia with kinking of the graft at theouter graft layer and intra luminal bulging of the inner graft. Postoperative computed tomographyshowed Dacron graft kinking at the mid part of the graft. Transthoracic echocardiography (TTE)revealed good function of repair aortic valve. Upon the redo midsternotomy, we found moderate kinkingof the graft at the outer graft layer and intra luminal bulging of the inner graft. We performedreconstruction of the aortic root with a new Dacron.CONCLUSION: The careful literature review showed that there are some few cases of hemolytic anemiaafter dissection, but no cases in which hemolytic anemia occurred in a patient with kinked Dacron graftafter surgery delete treated by replacement of kinked Dacron graft by new one.
