Right apical-posterior segmentectomy with abnormal anterior segmental bronchus and artery: a case report

Abstract

Background Displaced anterior segmental bronchus and pulmonary artery is extremely rare. A keen knowledge of such variations is required in the field of pulmonary segmentectomy, for unawareness of the structural variation could lead to intra- and postoperative complications. Case presentation A 50-year-old female presented to our department with suspected lung adenocarcinoma. Preoperative 3-dimensional computed tomographic bronchography and angiography revealed anterior segmental bronchus and anterior segmental pulmonary artery variation: the anterior segmental bronchus derived from the middle lobe bronchus, accompanied by a distally distributed anterior segmental pulmonary artery branch. A right apical-posterior segmentectomy using inflation-deflation technique was performed successfully. Conclusions The keen observation and proper application of modern imaging technology and operative technique could greatly aid segmentectomy, preventing intra- and postoperative complications from happening.

Anatomical distribution and clinical significance of translobar bronchi, arteries, and veins hidden in the interlobar fissure

“…Similarly, all the three translobar bronchi in this study were located in RUL. The B 2/2+3 that branched from B 4+5 within the fused HIF posed significant challenges in defining the boundary between RUL and RML during right upper lobectomy, because the HIFs were totally undeveloped in these patients ( 9 , 10 ). In this study, a new anomalous bronchial pattern was identified, namely common stem bronchus of RUL and RML.…”
