title: Mechanism and prevention of fixed high vascular resistance in autografted and allografted lungs.
abstract: The fixed vascular resistance observed in tranisplanted Ilunlgs and attriblted to denervation can be avoided by angioplastic wideniing of the pulmonary artery anastotosis. With distenisible arterial anrastomoses, aultografted an, d allografted Ilunzgs vasodilate niormzally with inicreased flow and cani sutstaini dogs whose contralateral pulmonary artery is ligated imumediately after lutng transplanitation.
