The Neck as a Preferred Recipient Site for Vascularized Composite Allotransplantation in the Mouse

Abstract

This novel mouse model allows performing vascularized composite allotransplantation with very high success and survival rates. The advantages over conventional models are multifold. A high-flow common carotid artery keeps the anastomosis patent, and diastolic suction of the heart reduces the risk of venous stasis and thrombus formation. Less destruction because of the heterotopic positioning of the hindlimb graft further reduces the associated mortality and morbidity in this fragile model.
