title: Effect of a kink in unilateral pulmonary artery anastomosis on velocities of blood flow through bilateral pulmonary vein anastomoses in living-donor lobar lung transplantation.
abstract: Intraoperative transesophageal echocardiography is generally performed to detect vascular complications during lung transplantation. We report a case with a kink in pulmonary artery (PA) anastomosis suggested by an abnormal flow profile of pulmonary vein (PV) anastomoses during living-donor lobar lung transplantation. During the transplantation, velocity of blood flow through the right PV anastomosis showed abnormal elevation. Then, the patient's PA pressure elevated abnormally and a kink in the left PA anastomosis was found. Careful monitoring of PV anastomoses may enable detection of not only an abnormality of PV anastomoses but also that of PA anastomoses, especially in living-donor lobar lung transplantation.
