Clinical experience with the extrathoracic introducer insertion technique.
The extrathoracic approach to transvenous introducer insertion into the subclavian vein was initially described as an alternative approach in "Safe Introducer Technique for Pacemaker Lead Implantation." Since this technique was so successful as an alternative approach, it was tried as the primary approach in 213 consecutive cases. The subclavian vein was cannulated in all cases. There were no introducer related complications. The extrathoracic approach cannulates the subclavian vein as it passes over the body of the first rib prior to entering the thoracic inlet. The technique includes maneuvering the introducer needle from the clavicle to the first rib by a series of partial withdrawals and reinsertions, visualized by fluoroscopy. The needle is advanced posteriorly along the rib until the vein is punctured. Orientation is maintained by touching the rib with each maneuver. The early results of the extrathoracic approach reinforces the belief that a complication-free, transvenous introducer approach can be achieved.
