Rehabilitation of Pulmonary Arteries in Pulmonary Atresia, VSD and Mapcas

Abstract

Patients with pulmonary atresia, Ventricular septal defect (VSD), and Major Aorto Pulmonary Collateral Arteries have a lung circulation depending primarily from perfusion by collateral arteries. A large proportion of them will have central pulmonary vessels connected to a variable proportion of segmental pulmonary vessels. A strategy of rehabilitation of central pulmonary vessels consist in the realization of shunts and conduits between the aorta or the right ventricle and these central vessels in order to obtain a dilatation of these vessels to assist the reconstruction of a pulmonary vascularization. Repetitive patch reconstruction of the central pulmonary vessels or even their replacement..
