Embolic capture angioplasty in peripheral artery interventions

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Peripheral artery disease (PAD) affects lower extremities, often requiring intervention.
• Complex lesions, including chronic total occlusions and in-stent stenosis, pose treatment challenges.
• Embolization of debris during angioplasty can lead to complications.

Purpose of the Study:

• To evaluate the single-center experience with the Proteus embolic capture angioplasty balloon catheter.
• To assess the efficacy of this device in treating symptomatic lower extremity PAD.
• To determine the rate of embolic debris capture during these procedures.

Main Methods:

• 36 lower extremity lesions in 30 patients with symptomatic PAD were treated.
• The Proteus catheter was used for angioplasty.
• Retrieved embolic debris was quantified using a debris score.

Main Results:

• Immediate procedural success was achieved in 86% of cases.
• Embolic debris was captured in 89% of treated lesions.
• No in-hospital serious adverse events were reported.

Conclusions:

• Embolic capture angioplasty with the Proteus catheter is technically feasible.
• The device effectively captures embolic debris during peripheral artery interventions.
• This approach appears safe for treating complex lower extremity PAD.
