Noncoronary transradial angioplasty with coronary equipment: a less invasive technique

As the safety and feasibility of the transradial approach for percutaneous coronary interventions have already been established by many series, we evaluate the safety and feasibility of this approach in noncoronary interventions such as renal, celiac, mesenteric, and subclavian angioplasty procedures. We present here our preliminary experience of noncoronary interventions via the transradial approach using coronary equipment with 100% technical and clinical success. Nine noncoronary interventions were performed in seven patients (five renal, two celiac, one mesenteric and subclavian angioplasty each). The advantage of this approach is that it limits arterial wall damage as well as potential distal embolization by the use of small guiding catheters and 0.014" guidewires. The only limitation of this approach for noncoronary interventions is the guiding catheter length in tall patients and the unavailability of large coronary balloons for subclavian, celiac, and renal interventions. With the miniaturization of equipment and improvements in technique, this approach will also become an excellent alternative for noncoronary interventions.
