RESUMEN
Negotiating the pacing lead into the right ventricle via left superior vena cava, at times, can be difficult. We report two such cases in which pacing leads were introduced into the right ventricle via left superior vena cava, with the help of stylet tip shaped into a large pigtail loop.

BACKGROUND: Subclavian vein puncture is commonly performed to insert the pacing lead for permanent pacemaker implantation. Our aim was to study the safety and feasibility of venogram-guided extrathoracic subclavian vein puncture for permanent pacemaker lead insertion. METHODS AND RESULTS: Sixty patients (32 males, and 28 females) underwent permanent pacemaker lead insertion by extrathoracic subclavian vein puncture at our institute between March 2002 and December 2002. Fifteen patients underwent dual-chamber and 45 single-chamber pacemaker implantation. All the patients underwent extrathoracic subclavian vein puncture guided by venogram, except 1 who underwent dual-chamber pacemaker implantation in whom the ventricular lead insertion was via the cephalic vein on an elective basis. The procedure was successful in all the patients. Inadvertent subclavian artery puncture occurred in 2 patients without any complication. There was no incidence of pneumothorax, hemothorax or pacemaker site infection. CONCLUSIONS: Venogram-guided extrathoracic subclavian vein puncture is safe and successful. It may be adopted as one of the preferred approaches for permanent pacemaker lead insertion.
