Detection of circulatory disturbance after pulmonary vein division during a living donor lobectomy.

Abstract

Indocyanine green (ICG) is widely used during thoracic surgery to enhance visualization, allowing assessment of the intersegmental plane based on intrapulmonary blood flow (Travis et al. in Ann Thorac Surg 108(2):363-369, 2019; Seshiru et al. in Gen Thorac Cardiovasc Surg 66(2):81-90, 2018). Using ICG to detect blood flow disruption after lung resection, however, has not been addressed. We therefore report a case in which the left lingular pulmonary vein was incidentally divided during left lower lobectomy in a living-lung donor. Intraoperative ICG-enhanced near-infrared fluoroscopic imaging to assess intrapulmonary blood flow detected the problem. We thus avoided potential postoperative residual lung complications in this patient.
