P2.05-11 - 3D CT Is Useful for Segmentectomy but Is Not Always True (Now Available) (ID 235)
10:15 - 18:15 | Author(s): Hironori Hinokuma
- Abstract
Background
Pulmonary vessels and bronchus have a lot of variations. 3D CT is a good guide for segmentectomy, but sometimes shows images different from real anatomy of the lung structures. The aim of this study is to evaluate effectiveness and problems to apply 3D CT for segmentectomy.
Method
From July 2018 to December 2018, 78 cases underwent chest surgery in our hospital. Using contrast enhanced volume dataset of 64-row CT, pulmonary artery (PA) was separated form pulmonary vein (PV) based on the difference of CT number between them. Image interpretations for surgery were performed by one experienced thoracic surgeon (TM) using axial, sagittal, coronal images, and 3D image containing PA, PV, bronchus, and lobar fissure in this study.
Result
Of 29 case underwent lobectomy or segmentectomy, 23 cases were performed 3D CT. Failure to discriminate among PA, PV, and other structures were observed in 9 cases: Ascending A2 → branch of V2 in 2 cases; V2t → Ascending A2 in 4 cases; A3a → branch of V3 in 1 case; V3b → branch of A3 in 1 case; V1a → A1 in 1 case; V1 runs dorsal side of A1,3 → part of A1,3 in 1 case; #12l →lower lobe PA in 1 case.
Case 7 underwent right S1 segmentectomy. 3D CT showed recurrent A2 runs ventral side of B1, but did not show V1 runs dorsal side of A1,3 which was found during surgery.
Conclusion
3D CT is useful for segmentectomy to understand the lung anatomy, but does not always give us true anatomy. Surgery should be performed keeping the fact in mind.
