Transcatheter coil embolization of abnormal vascular connections using a new type of delivery catheter for enhanced control.
A new type of delivery catheter, designed with a 0.033-inch distal tip that grips a 0.038-inch Gianturco coil, was used to occlude 61 abnormal vascular connections in 44 patients with a complete closure rate of 87%. Withdrawal (n = 6) or repositioning (n = 2) of an inappropriately positioned coil was necessary in 8 of 44 patients, and was successfully achieved in all by the delivery catheter without need for additional equipment.
