Percutaneous radial access for peripheral transluminal angioplasty

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Endovascular Interventions

Background:

• The radial approach is increasingly favored for coronary percutaneous transluminal angioplasty (PTA) due to reduced vascular complications.
• This study investigates the initial outcomes of utilizing radial access for peripheral PTA.

Purpose of the Study:

• To evaluate the feasibility and preliminary results of performing peripheral PTA using a transradial approach.
• To assess the safety, efficacy, and outcomes of radial access in peripheral interventions.

Main Methods:

• Peripheral PTA was performed in 24 patients via left radial access for TransAtlantic Inter-Society Consensus A or B lesions.
• Specialized equipment including a 110-cm introducer and 180-cm balloons/stents was used.
• Data were prospectively collected, with a median follow-up of 8 months.

Main Results:

• Technical success was achieved in 91% of patients (20/22).
• Indications included hostile groins (50%) and infrainguinal lesions (17%).
• Complications included radial artery rupture (8%) and occlusion (13%); however, 91-93% freedom from revascularization was observed at 6 months.

Conclusions:

• Transradial peripheral PTA is feasible and can be an alternative to brachial access.
• Complication rates require further investigation in larger studies to overcome the learning curve.
• Wider adoption necessitates smaller sheaths, longer devices, and specialized rescue equipment.
