Insights
Endovascular treatments for severe lower extremity peripheral artery disease (PAD) show promise, particularly stent-based revascularization for complex TASC C/D lesions. Ongoing technological advancements improve outcomes for patients with claudication.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Therapy
Background:
- Peripheral artery disease (PAD) significantly impacts adult health, causing morbidity and mortality.
- Transatlantic Inter-Society Consensus II (TASC II) guidelines classify PAD lesion complexity.
- TASC C/D lesions represent complex cases requiring advanced intervention.
Purpose of the Study:
- To review endovascular approaches for TASC C/D lower extremity PAD in claudication patients.
- To assess the efficacy of current endovascular strategies for complex PAD.
- To identify data limitations and future directions in PAD treatment.
Main Methods:
- Systematic review of published data on endovascular interventions for TASC C/D lower extremity PAD.
- Analysis of studies focusing on patients with claudication.
- Evaluation of procedural success, quality of life, and patency rates.
Main Results:
- Endovascular approaches demonstrate success in procedural outcomes, quality of life, and patency for TASC C/D PAD.
- Stent-based revascularization is favored for aorto-iliac and femoral-popliteal arteries.
- Technological advancements enhance endovascular intervention success for complex lesions.
Conclusions:
- Endovascular therapy, especially stent-based revascularization, is effective for complex lower extremity PAD (TASC C/D).
- Methodological improvements in studies are needed for clearer evidence.
- Continued innovation in endovascular technology offers improved treatment options.
Abstract:
Peripheral artery disease (PAD) burdens a significant number of adult Americans and is associated with significant morbidity and mortality. The Transatlantic Inter-Society Consensus II (TASC II) guidelines standardize the degree of disease burden in individual vessel segments by assigning grades correlating to the complexity of lesion intervention. We sought data regarding endovascular approaches to lower extremity PAD in TASC C/D lesions in patients with claudication. Published data in these patients have demonstrated success in terms of procedural success, quality of life metrics, and intermediate to long-term primary patency rates. However, data have suffered from several methodological shortcomings including enrollment of heterogenous patient populations, inconsistent outcome reporting, and lack of appropriate control groups. The majority of data is positive in favor of using stent-based revascularization in both the aorto-iliac and femoral-popliteal arteries. Additionally, continual technological evolution in the field has resulted in a growing armamentarium for the endovascular operator beyond balloon angioplasty that aids in the success of endovascular intervention to these complex lesions.
