Abstract:
Objective:To explore the clinical value of CT identification of vascular variations in the dorsal side of right middle segmental bronchus before thoracoscopic lobectomy.Methods:A retrospective analysis was conducted on the clinical data of 3 patients who underwent thoracoscopic lobectomy at Shanxi Province Cancer Hospital from July 2022 to March 2024 and had a variant blood vessel on the dorsal side of the right middle segmental bronchus. Relevant literature was also reviewed.Results:Among the 3 patients, 2 were female and 1 was male, with ages of 66, 50 and 69 years old, respectively. Prior to admission, imaging examinations revealed space-occupying lesions or nodes in the right lung, and all patients underwent thoracoscopic right lobectomy and systematic lymph node dissection. Postoperative pathology diagnosed adenocarcinoma in the lower lobe of the right lung, cystic adenoma in the upper lobe of the right lung and invasive adenocarcinoma in the lower lobe of the right lung. Preoperative chest CT scans revealed an abnormal blood vessel on the dorsal side of the right middle segmental bronchus, and its direction and confluence with the right lower pulmonary vein or left atrium were observed on the downward CT imaging. This was confirmed and treated accordingly during surgery. All 3 patients had no postoperative complications and recovered smoothly. Follow-up showed good health status.Conclusions:The vascular variation on the dorsal side of the right middle segmental bronchus has obvious characteristic manifestations on chest CT. Identifying the variation by CT before thoracoscopic lobectomy can effectively ensure surgical safety and reduce the occurrence of postoperative complications.
