Pulmonary Arteries: Surgical Point of View
Surgical repair of the pulmonary artery (PA) branches encompasses many different clinical scenarios and technical challenges. Branch PA stenosis can occur either primarily or following a previous attempt at surgical repair. In cases of complex congenital heart disease (CHD) requiring reoperations or staged palliation, surgical patch angioplasty is often needed and may prove challenging. Aside from elective indications, surgical PA plasty is necessary following complications of percutaneous stent implantation such as PA dissection or rupture, stent migration, suboptimal stent expansion, stent thrombosis, stent restenosis, airway compression, and inhibition of PA growth. The main challenge in PA surgery is to obtain a spatially pleasing reconstruction in three dimensions.
