Upper extremity deep vein thrombosis as an uncommon complication of pacemaker implantation: a case report.

Venous complications of pacemaker implantation rarely cause immediate clinical problems. An 89-year-old man, without thrombophilia, 4 weeks after a pacemaker implantation experienced functional impotence of the left arm that appeared warm, reddened, oedematous and painful. Color Doppler Ultrasonography revealed a thrombosis of the axillary vein extended to the proximal third of the ulnar vein. In our opinion, upper extremity deep vein thrombosis (UEDVT) represents an important complication of post-surgical pacemaker implantation that should be suspected early, even without specific symptoms and thrombophilia.
