Thoracoacromial artery injury after tube thoracostomy for pneumothorax.

In this case, a patient presented in a delayed fashion after blunt trauma is found to have a large left-sided pneumothorax, and tube thoracostomy is performed. After placement of the apically oriented tube, he developed haemothorax. CT imaging showed an area of questionable extravasation from the left subclavian artery, directly anterior to the thoracostomy tube. His haemothorax was refractory to adequate drainage with a new thoracostomy tube. He ultimately required angiography, coil embolisation and covered stent placement, followed by thoracoscopic evacuation of the haemothorax.
