Cadaveric training model for the management of type B aortic dissection using thoracic endovascular aortic repair along with the PETTICOAT technique

Abstract

This model gives residents and fellows practice in the surgical repair of a type B aortic dissection using thoracic endovascular aortic repair implantation by the Provisional Extension To Induce Complete Attachment (PETTICOAT) technique. A human cadaveric model was created to simulate the procedure. A Dacron graft was pulled into the aorta distal to the left subclavian artery using two glidewires. Imaging confirmed the creation of a second lumen by the graft positioned within the aorta to simulate an aortic dissection. The PETTICOAT technique was then implemented with the implantation of a Cook Dissection stent. This proved the method to be a reproducible means to train residents and fellows in type B aortic dissection repair using the PETTICOAT technique.
