About this study

Official title: Application de l'oxymétrie Dynamique Pour le Diagnostic Des Syndromes de défilés Thoraco-brachiaux Systematic Transcutaneous Oxymetry Use in Thoracic Outlet Syndrom

The measurement of the transcutaneous oxygen partial pressure (TCPO2) at exercise is, to our knowledge, the only method to estimate during the exercise the importance of ischemia segment of limb by segment of limb bilaterally and carry on. The diagnosis of thoracic outlet syndrome causing remains difficult and dependent operator in ultrasound because of the risk of false positive (loss of signal) or false negative (insufficient effort, inappropriate movement).

Our main hypothesis is the existence of significant measurable ischemia in the forearm by transcutaneous oximetry during the maneuvering of the "candlestick".

In the event of failure of this maneuver, the other maneuvers such as those of Wright, Roos, Tinel and Adson will be realized.

In this study we want to evaluate the possibility of using dynamic transcutaneous Oximetry as a tool for evaluating ischemia in case of suspicion of thoracic outlet syndrome causing.

Read the detailed description

Patients referred for suspected thoracic outlet syndrome causing and healthy asymptomatic subjects will be included.

After signing the consent, the subject will have a clinical and paraclinical examination. Age, sex, height, weight, side of clinical symptomatology will be collected. Medical history current treatments will also be noted.

The examination of transcutaneous oximetry dynamic measurement with palmar face of both forearms during two consecutive maneuvers known as the "candlestick" (hands up). The most symptomatic arm value in patients and the dominant arm in the control group will be noted. In case of DROP between 0 and -25 mmHg, in addition to the maneuvering of the "candlestick", the other maneuvers such as those of Wright, Roos, Tinel and Adson will be realized.

The results of any additional examinations and / or pre- and post-operative consultations will be collected.

Subjects complete two Quality of Life questionnaires: the SF-12 (Short Form 12) and the DASH questionnaire (Disabilities of the Arm, Shoulder and Hand).

Added by an amendment : Photoplethysmography has already done its proofs to determine the thoracic outlet syndrome diagnotic. Combine with a camera Kinect, they should determine the angle of appearance of compression in the 3 dimensions of space.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Transcutaneous OximetryDiagnostic test

    The examination of transcutaneous Oximetry dynamic measurement with palmar face of both forearms during two consecutive maneuvers known as the "candlestick" (hands up).

  • PhotopletysmographyDiagnostic test

    Maneuvers are repeted with the photoplestysmography sensors and in front of a Kinect camera.

  • Questionnaires of Quality of Life (QoL)Other

    Each subject complete 2 QoL questionnaires : Sf-12 (Short Form 12) and DASH (Disabilities of the Arm, Shoulder and Hand).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Decrease from Rest of Oxygen Pressure (DROP) during manoeuvers in patients and controls.

    Difference in DROP observed in the symptomatic arm of patients with suspected thoracic outlet syndrome compared to the dominant arm in controls

    Measured: inclusion

Secondary outcomes (3)
  1. Presence of stenosis or occlusion on angiography

    The performance and cutoff of the DROP will be studied with the AUC (ROC curve) to predict a stenosis on angiography versus no stenosis in patients.

    Measured: 24 months

  2. POsitive and negative DROP results

    To determine the proportion of false positive and false negative results in controls using the cutoff determined in outcome 2

    Measured: 24 months

  3. Angle of appearance of the compression observed on PPG

    By combining the photopletysmography and a camera Kinect, it is possible to exactly determine the angle of appearance of the compression

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A study testing Transcutaneous Oximetry, Photopletysmography and Questionnaires of Quality of Life (QoL) in people with Thoracic Outlet Syndrome, run by University Hospital, Angers at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Decrease from Rest of Oxygen Pressure (DROP) during manoeuvers in patients and controls. (time frame: inclusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03355274, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Mar 2025.
