A Comparative Analysis of Mid- to Long-Term Outcomes of Paclitaxel-Coated Balloon Angioplasty With Adjunctive Debulking Versus Paclitaxel-Coated Balloon Angioplasty Alone for the Treatment of Chronic Femoropopliteal Artery Occlusions

This study aims to compare mid-to long-term outcomes of paclitaxel-coated balloon angioplasty with adjunctive debulking versus paclitaxel-coated balloon angioplasty alone for the treatment of chronic femoropopliteal artery diseases.

Detailed Description

Chronic femoropopliteal artery occlusion, particularly in long lesions, remains a significant challenge in endovascular treatment of lower extremity arterial disease due to its high occlusion burden and severe vascular calcification. In recent years, with the continuous advancement of endovascular techniques and devices, especially the emergence of the "leave nothing behind" concept, Drug-Coated Balloon (DCB) angioplasty has become a mainstream approach for treating femoropopliteal occlusions. While DCB offers excellent long-term patency and preserves future treatment options, adjunctive debulking procedures-a category of techniques that physically remove or ablate plaque prior to DCB dilation to achieve a larger, smoother lumen-have gained attention. These techniques primarily include atherectomy, laser ablation, and directional atherectomy. They can address more complex lesions and offer potential benefits such as enhanced drug absorption, reduced elastic recoil, and decreased need for bailout stenting. However, they also carry risks, including distal embolism and perforation. Consequently, the comparative efficacy between DCB alone and DCB combined with debulking measures remains uncertain, and the choice of treatment strategy still largely depends on operator experience. Therefore, an in-depth investigation is necessary to compare the efficacy and safety of these two approaches to inform and guide optimal clinical decision-making.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
