A case of left main pulmonary artery occlusion test under general anesthesia with isolated pulmonary ventilation in a patient with left lung cancer after Fontan surgery

Abstract

　In recent years, the outcomes of Fontan surgery have been improving, and we are increasingly performing anesthesia for malignant disease surgery on post-Fontan patients. However, the postoperative condition of each Fontan patient varies making it difficult to determine surgical tolerance. It is also necessary to consider cardiac function, complications associated with Fontan circulation, surgical site, surgical time, and magnitude of invasion.

　In our case, a left upper lobe resection was planned for a patient with left upper lobe lung cancer after Fontan surgery. We performed the left main pulmonary artery occlusion test for preoperative evaluation under general anesthesia with isolated lung ventilation to help determine the surgical tolerance.
