Intravascular repositioning of a ventriculoatrial shunt

Abstract

✓ Intravascular repositioning of a misdirected ventriculoatrial shunt from the left innominate vein into the right atrium was accomplished using a Muller guidewire deflector system. The guidewire and its surrounding small polyethylene catheter were inserted into a left superficial saphenous vein and advanced through the right side of the heart into the superior vena cava. The deflector system was activated and easily hooked the misplaced ventriculoatrial catheter. With gentle traction it was repositioned in the right atrium. The simplicity and safety of this approach make it recommended for use in infants and children.
