Blind Extrathoracic Subclavian Venipuncture for Temporary Pacing Lead Insertion:- A 4 Year Experience in 760 Patients.

Abstract

Seven hundred and sixty patients admitted in Cardiology Dept. Mayo Hospital, Lahore from Feb.1994 to Jan 1998 were inserted temporary pacing lead for different indications. Modification of the percutaneous technique for extrathoracic subclavian venipuncture proposed by Magney and colleagues for permanent pacing lead placement was used. Before puncturing bony landmarks were marked on the skin according to Magney’s description to identify the needle entry point. Then the venipuncture was accomplished by inserting the needle through a standard infraclavicular land mark. 760 patients were approached with this technique with in a span period of four years. This technique was successful in 684 (90%) cases with first puncture, additional 35 (5%) with second attempt, while additional 14 (2%) patients required multiple attempts or the change of the site. In rest 3% the procedure was completed using other routes. Patients were followed till the removal of temporary pacing wire or implantation with permanent pacing system. In the present study the blind approach to the extrathoracic portion of the subclavian vein proved to be safe and effective for pacing lead insertion. Further observations are Required to establish whether this method decreases the complication rate.
