Fig 1 The hybrid prosthesis (Chavan-Haverich endograft, Curative GmbH, Dresden, Germany) made of a woven vascular prosthesis with stainless stents affixed to the inner aspects at the distal end. The proximal end consists of a Dacron sleeve (DuPont, Wilmington, DE) ready for conventional surgical handling. (L = length.)
