Cervicothoracic tumors: Results of resection by the "hemi-clamshell" approach
To the Editor:
We read with interest the article of Korst and Burt
1 concerning the surgical treatment of the tumors involving the cervicothoracic junction using the hemi-clamshell approach. We agree with the authors that, among the different surgical accesses described, the hemi-clamshell is the technique that offers the best chances of removing tumors located in this region apart from the structures involved and the size of the tumor. Nevertheless, in using this approach, we have noticed difficulties in exposing the distal part of the subclavian vessels in 2 cases in which we recently operated. The first was a cancer of the left upper lobe involving also the vertebral bodies from T1 to T3, and the second was a big apical cancer of the left upper lobe involving the subclavian artery and the first rib. In both cases we have modified the standard hemi-clamshell approach by dividing the first costal cartilage and the costoclavicular ligament, thereby obtaining a remarkably improved exposure with a safe control of the distal part of the subclavian vessels. We have taken this technical variation from our experience using the transmanubrial osteomuscular sparing approach proposed by Grunenwald and Spaggiari
2 that gives very good exposure of the structures of the thoracic inlet/outlet, even though in our series of 10 patients, 6 required an additional posterolateral thoracotomy to complete the pulmonary upper lobectomies. We believe that the modified hemi-clamshell approach can be a more useful surgical technique in performing radical anatomic resections of pulmonary apical tumors invading the thoracic inlet/outlet, by avoiding the limitation of not completely controlling the subclavian vessels and also permitting resection in cases of invasion of the posterior chest wall.
