Subselective diagnostic and interventional arteriography using a simple coaxial catheter system

A simple, commercially available 6.5-3.0 French coaxial catheter system was used to obtain the subselective catheter position for diagnostic or interventional (drug infusions, embolizations) angiography. The system was employed 81 times in 75 patients without complication. We describe the catheter system, techniques for its use, and its clinical applications.
