Efficacy of Multichannel Balloon Angioplasty in Calcified Common Femoral Artery Lesions

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Endovascular Interventions

Background:

• Severe calcification of the common femoral artery poses a significant challenge for endovascular treatment.
• Traditional angioplasty techniques may be less effective in treating heavily calcified lesions.
• Minimally invasive approaches are sought to improve outcomes for peripheral artery disease.

Purpose of the Study:

• To evaluate the efficacy and safety of multichannel balloon angioplasty for treating severely calcified common femoral artery stenosis.
• To assess the impact of this novel technique on ankle-brachial index and arterial patency.

Main Methods:

• Seven patients with severe common femoral artery stenosis underwent multichannel balloon angioplasty.
• Guidewires were advanced through separate channels within the calcified plaque.
• Balloon angioplasty was performed sequentially through each channel.

Main Results:

• The ankle-brachial index improved significantly, from an average of 0.49 to 0.89 post-procedure.
• Six out of seven patients maintained patent arteries at a median follow-up of 13 months.
• The procedure demonstrated technical feasibility in expanding calcified lesions.

Conclusions:

• Multichannel balloon angioplasty is a potentially effective endovascular intervention for severely calcified common femoral artery stenosis.
• This technique shows promise in improving limb perfusion and maintaining long-term arterial patency.
• Further studies are warranted to confirm these findings in larger patient cohorts.
