Late Pseudoaneurysm After Access Site Closure with Manta in Transfemoral Aortic Valve Implantation
2019
Introduction Access site vascular complications in transfemoral transcatheter aortic valve implantation (TF-TAVI) are still a major concern. Recently, a novel collagen plug based closure device (Manta) was introduced. The results from the first reports on Manta are very promising, but not much is known about the long-term patency. Report A case of late
pseudoaneurysmafter access site arterial closure with Manta in TF-TAVI is described. The patient presented five weeks after left sided TF-TAVI with pain and
claudicationlike symptoms in the left leg. CT angiography revealed a
pseudoaneurysmat the puncture site. The patient was successfully treated by
vascular surgery. Discussion The results from recent peri-
operative reportson the Manta vascular closure device (VCD) are promising, but not much is known about the long-term patency. In the present report a patient is described who developed a
pseudoaneurysmseveral weeks after access site closure with Manta. To the authors' knowledge, no such late access site complications after use of the Manta VCD have been reported previously.
