BACKGROUND Axillary venipuncture for pacemaker lead implantation has been demonstrated to be an effective method without fatal complications encountered with standard subclavian access approach, but the relatively high complexity limits its clinical practicability. OBJECTIVE We are proposing a simple technique for axillary venipuncture using single point on clavicle as anatomical landmark with the possibility of alternative fluoroscopic assisted puncture as a backup. METHODS Connecting point of medial to middle third of clavicle is located as the landmark. Deflected lateral 45°from sagittal line, an 18-guage needle tip is laid on the point and tangential to upper border of clavicle. Penetrated from the hub site, the needle is directed to the landmark at approximately 30-45° relative to body surface for venipuncture. If blind puncture failed, an alternative fluoroscopic method is performed. Upon successful venipuncture, a guide wire is positioned in inferior vena cava and a skin incision and subcutaneous pocket is made at the puncture site. RESULTS Axillary vein puncture was successful for 106 of 113 patients (93.8%) in the study with mean access time of 3.6 ± 1.4 min. In 84 patients (74.3%), the vein was cannulated by blind puncture, and fluoroscopy guided method was required in other 22 patients (19.5%). The puncture of axillary artery occurred in one patient (0.09%) and no haemorrhage was observed after local pressure. No pneumothorax, hemothorax, or brachial plexus injury was found. CONCLUSIONS The approach of axillary vein puncture using single landmark on the clavicle is simple, effective and safe for pacemaker lead implantation.
