Hemothorax--a complication of subclavian vein cannulation.

Massive bleeding into pleural cavity after subclavian vein cannulation is a rather rare but very serious complication. Usually laceration of the venous wall is the cause. In patients where conservative treatment, i.e. pleural drainage, maintaining the circulatory volume, treatment of possible coagulopathy, etc. is ineffective, surgery has to be performed. Bleeding can be surgically managed either from posterolateral thoracotomy or direct subclavian vessel revision is possible after partial resection of the clavicle. Brachiocephalic vein bleeding can be approached and managed through median sternotomy. We present a case report of 22-year old man with hemothorax after subclavian vein cannulation. In our patient only complex surgical procedure enabled proper management of bleeding complication.
