Abstract
During the treatment of 86 patients with video-assisted thoracoscopic surgery (VATS) anatomical resection (include segmentectomy) within the last two years, we have encountered five patients (5.8%) with anomalous venous returns. Anomalous returns included: 1) common trunk of the left pulmonary vein; 2) right middle pulmonary vein (V4) draining into the inferior pulmonary vein (IPV); 3) left lingular vein (V4+5) draining into the IPV; 4) right posterior pulmonary vein (V2) draining directly into the left atrium; and 5) left upper lobe vein draining into the left innominate vein. If a surgeon were to perform VATS lobectomy without paying attention to these anomalies according to the affected lobe, serious surgical complications might result. Multi-detector row angiography is useful for recognizing such anomalies before surgery and allow safe VATS lobectomy.
