Abstract

Background: Reliable and rapid anastomosis is critical in lung transplantation. The purpose of this study is to show the appropriateness of sutureless anastomosis of the pulmonary artery using a nonpenetrating vascular clipping device. Methods: The left lung was excised and the cranial lobe was transplanted autologously in 9 dogs. The anastomosis of the left main pulmonary artery (PA) (1 cm) was performed using a vascular clipping system. Results: PA anastomosis was performed in 7 dogs in 8 to 13 minutes. The endovascular surface of the anastomotic site was smooth, and passage of silicone rubber through the anastomosis was good 14 or 28 days after surgery. Microscopic examination of the anastomotic sites showed excellent healing without evidence of intimal hyperplasia. Conclusions: The vascular clipping system facilitates anastomosis of the PA in lung transplant surgery.
