En Bloc Right Upper Bilobectomy For a Patient With Incomplete Minor Fissure and Multiple Anomalies of the Right Superior Pulmonary Vein.

Variations in the anomaly of the right superior pulmonary vein can lead to perioperative complications if misunderstood. Additionally, incomplete fissures increase the complexity of performing pulmonary anatomical resection. Therefore, accurate preoperative anatomical assessment using three-dimensional computed tomography is crucial for ensuring safe surgery. We herein report a case of en bloc right upper bilobectomy via uniportal video-assisted thoracic surgery in a patient with an incomplete minor fissure and a complex anomaly of the right superior pulmonary vein.
