Comparative Clinical and Economic Analysis of Percutaneous vs. Open Access for Endovascular Aortic Repair - a Prospective, Randomised Trial.

Introduction:

Endovascular repair of aortic aneurysms (EVAR) is a routine procedure in vascular surgery and associated with less perioperative complications compared to open aortic repair. Continuous improvement of endovascular techniques is crucial for sufficient patient care, especially in elderly with serious comorbidities. Percutaneous access (pEVAR) to the femoral artery is associated with less wound complications when performed in suitable patients. Prospective data about economic feasibility and exact duration of the technique itself compared to the open access during the surgery are missing.

Methods and data collection:

The primary endpoints of this prospective randomised single center trial are cost and time differences of open vs. percutaneous access. Each Patient enrolled in the study will receive percutaneous on one side and surgical access on the other side of the groin for femoral artery access.

The punction site will be closed using the Perclose ProGlide Suture-Mediated Closure System manufactured by Abbott Vascular. This device works through stiff wire guided delivering of a monofilament suture to the femoral artery punction site. After finishing endovascular procedures for aneurysm repair, the thereby laid sutures are tightened to achieve hemostasis. This system is suitable for sheath sizes up to 21 F (.28 inch).
