Perkutane transfemorale Implantation einer neuen, flexiblen thorakalen Aortenendoprothese unter Verwendung eines perkutanen Nahtsystems zum Gefäßverschluss - erste Erfahrungen

Percutaneous Transfemoral Placement of a New Flexible Stent-Graft Into the Thoracic Aorta Followed by a Percutaneous Suture-Mediated Closure of the Access Site - Initial Experience. Purpose: To evaluate the transfemoral placement of a new, flexible stent-graft into the thoracic aorta and the suture-mediated closure of the femoral access. Patients and Methods: Five patients were treated endovascularly with a stent-graft for an aneurysm (n = 3) or acute dissection (n = 2) of f the thoracic aorta via a femoral 24 F sheath. The femoral access site was closed with two suture-mediated closure devices after placement of the stent-graft. Results: The aneurysm or the false lumen was excluded from perfusion by the placement of the stent-graft in all patients. Hemostasis at the femoral access site was successful in all patients with the percutaneous suture device. A minor stenosis of the femoral artery was found angiographically in four patients after suture-mediated closure. Besides a reversible renal failure due to the medically induced hypotension for the treatment of an acutely ruptured aneurysm, no complications resulted from the stent-graft placement or the percutaneous suture. Conclusion: The percutaneous transfemoral placement of stent-grafts in the thoracic aorta using a suture-mediated closure of the access site is technically feasible. Long-term results of the technique have to be awaited.
