Case ReportsRight cervical aortic arch with aberrant left subclavian artery.
The combination of right cervical aortic arch, aberrant retroesophageal left subclavian artery originating from a Kommerell's diverticulum, and a ligamentum arteriosum, constitutes a rare form of vascular ring. Two patients aged 21 days and 54 years, who were diagnosed by multislice 3-dimensional computed tomography and magnetic resonance imaging, underwent surgical division of a vascular ring. The adult required resection of a Kommerell's aneurysm and subclavian artery reimplantation.

Case ReportsRetrieval of broken paravertebral catheter by video-assisted thoracic surgery.
A paravertebral catheter was placed in a 34-year-old man to provide analgesia after a right upper lobectomy. On removal, the catheter broke within the chest wall. Although bedside exploration and computed tomography scanning failed to locate it, the 13-cm long retained fragment was easily retrieved by video-assisted thoracic surgery, using a single-port technique.
