Reconstruction using a divided latissimus dorsi muscle flap after conventional posterolateral thoracotomy and the effectiveness of indocyanine green-fluorescence angiography to assess intraoperative blood flow

摘要

In most general thoracic operations performed via standard posterolateral thoracotomy, such as for descending aortic aneurysms and lung cancer, the latissimus dorsi (LD) muscle is divided. However, division of the LD can hamper reconstructive surgery because the initial operation creates unstable blood flow to the divided LD. We conducted this study to assess blood flow in a divided distal LD muscle flap using intraoperative indocyanine green-fluorescence angiography (ICG-FA) with the Hyper Eye Medical System(A (R)) (Mizuho Medical Co., Ltd., Tokyo, Japan).
