Comparing BlueDop Vascular Expert to Ankle-Brachial Index in the Identification of Peripheral Vascular Disease

May 30, 2024 updated by: Dakota Vascular

Comparing BlueDop Vascular Expert to Ankle-Brachial Index in the Identification of Peripheral Vascular Disease in All-comers and Diabetic Patients

To compare the screening capabilities of the BlueDop Vascular Expert (BVE) and ankle brachial index (ABI) in peripheral arterial disease for all-comer patients and those with diagnosed diabetes mellitus.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This retrospective and prospective single-center study to compare the accuracy and screening capabilities of BVE and ABI with that of conventional Full Leg Arterial Duplex (FLAD) was performed at a private clinic in Sioux Falls, South Dakota, USA, with data collected from March 2023 to March 2024. Currently, BVE carries the European CE Mark but does not yet have FDA approval for use in the United States. This study was undertaken with local IRB approval.

Patients 18 years or older who presented to the center were consented to have BVE, ABI, and FLAD performed. BVE examination of lower extremity arteries were performed following the instruction for use (IFU). All examinations were performed by the same two registered vascular technologists. FLAD ultrasound was carried out with waveform interpretation interpreted by an outside cardiothoracic surgeon who specializes in treatment of arterial disease to determine the presence or absence of disease.

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

Study Population

This retrospective and prospective single-center study to compare the accuracy and screening capabilities of BVE and ABI with that of conventional Full Leg Arterial Duplex (FLAD) was performed at a private clinic in Sioux Falls, South Dakota, USA, with data collected from March 2023 to March 2024.

Description

Inclusion Criteria:

  • Patients 18 years or older who presented to the center were consented to have BVE, ABI, and FLAD performed.

Exclusion Criteria:

  • Patients were excluded who had incomplete or inadequate data, if they were known to be currently pregnant, or if they had contraindications to Doppler ultrasound.

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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

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.
March 1, 2023

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.
March 1, 2024

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
