[Femoropopliteal laser recanalization--a multicenter study].

Area of Science:

• Vascular Surgery
• Minimally Invasive Procedures
• Laser Technology in Medicine

Background:

• Peripheral artery disease (PAD) significantly impacts patient mobility and quality of life.
• Femoro-popliteal occlusions present a common and challenging manifestation of PAD.
• Traditional surgical interventions carry significant risks and limitations.

Purpose of the Study:

• To evaluate the efficacy and safety of laser-assisted angioplasty for femoro-popliteal occlusions.
• To determine the initial recanalization and long-term patency rates.
• To assess the complication rates and need for subsequent surgical intervention.

Main Methods:

• A multicenter study involving 259 patients with femoro-popliteal occlusions.
• Standardized treatment protocol using Nd-YAG laser with a sapphire-probe catheter.
• Assessment of initial recanalization, dissection/perforation rates, and emergency surgery requirements.
• Long-term follow-up to determine patency and cure rates.

Main Results:

• Initial recanalization rate of 84% for femoro-popliteal occlusions (mean length 7.5 cm).
• Dissection or perforation occurred in 10% of cases; emergency surgery was needed in 1.1%.
• Two-year primary patency rate for successfully recanalized arteries was 74%; cumulative cure rate was 62%.

Conclusions:

• Laser-assisted angioplasty is a feasible and effective primary treatment for femoro-popliteal occlusions.
• The procedure demonstrates acceptable complication rates and good long-term outcomes.
• Further research can optimize patient selection and procedural techniques for improved results.
