Retrospective Analysis of Balloon Expandable Covered Stenting in the Common Femoral Artery (BEST-CFA)

November 20, 2023 updated by: Csaba Csobay-Novák MD PhD, Semmelweis University Heart and Vascular Center
The aim of this study is to evaluate the safety and efficacy of balloon expandable covered stenting of access complications, stenoses or pseudoaneurysms of the common femoral access.

Detailed Description

In the past decades, there has been a paradigm shift in the field of vascular surgery, with endovascular interventions replacing traditional open surgical procedures on an increasing scale. Most of these interventions are performed via the femoral artery. Even with modern percutaneous vascular closure devices, interventional laboratories report a high incidence of vascular complications, most commonly bleeding. Interventional procedures are gaining ground as an alternative to surgery. Having regard to the fact that femoral arteries are in constant motion due to their location and are subject to intense bending forces, the long-term durability of stents has been questioned in the absence of long-term follow-up data. There is currently no broad consensus on the strategy of care for vascular complications, and overall the decision is left to the discretion of the interventionalist, largely determined by the available local resources and infrastructure. The use of covered stents is an option for endovascular treatment of the complications: the self expanding nitinol framed stent graft with polytetrafluoroethylene (PTFE) coating and the cobalt-chrome framed, also PTFE coated balloon expandable stent. The main aim of this research is to analyse the short- and long-term outcome of these alternatives.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Description

Inclusion Criteria:

  • over 18 years of age
  • intervention from the left or right common femoral artery
  • access complication treated by balloon expandable covered stent(s) or common femoral artery disease treated by balloon-expandable covered stent(s)

Exclusion criteria:

  • none

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary patency rate
Time Frame: 1 year
Number of patent common femoral arteries at one year
1 year
Reintervention rate
Time Frame: 1 year
Number of reinterventions on the treated vessels
1 year
Amputation rate
Time Frame: 1 year
Number of amputations at the side of the treated common femoral artery
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Restenosis rate
Time Frame: 1 year
Number of significant (peak systolic velocity ratio > 2,4) restenoses found at one year
1 year
Walking disturbance rate
Time Frame: 1 year
Number of any new onset walking impairment
1 year

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
