Three-dimensional multidetector computed tomography may aid preoperative planning of the transmanubrial osteomuscular-sparing approach to completely resect superior sulcus tumor

Abstract

The anterior transcervical-thoracic approach clearly exposes the subclavian vessels and brachial plexus. We believe that this approach is optimal when a superior sulcus tumor (SST) invades the anterior part of the thoracic inlet. However, this approach is not yet widely applied because anatomical relationships in this procedure are difficult to visualize. Three-dimensional tomography can considerably improve preoperative planning, enhance the surgeon's skill and simplify the approach to complex surgical procedures. We applied preoperative 3-dimensional multidetector computed tomography to a case where an SST had invaded the anterior part of the thoracic inlet including the clavicle, sternoclavicular joint, first rib, subclavian vessels and brachial plexus. After the patient underwent induction chemotherapy, we performed the transmanubrial osteomuscular-sparing approach and added a third anterolateral thoracotomy with a hemi-clamshell incision and completely resected the tumor.
