[The experience of a new double-catheter introducer for simultaneous bilateral internal iliac angiography]

We developed a new 8F catheter-introducer system designed for simultaneous insertion of two catheters into each internal iliac artery via a single puncture. This introducer has a common distal limb and a pair of proximal limbs connected in a Y-shaped fashion. Each of the proximal limbs has its own check valve and flushing side arm, through which one can pass two catheters separately. We succeeded in placing each of two catheters at desired sites in three cases of pelvic angiography. This system will be of great help in pelvic angiography and infusion-chemotherapy when bilateral catheterization is required.
