During photo-plethysmography, completing a 30 s 90\u00b0 abduction, external rotation (\u2018surrender\u2019 position) by addition of a 15 s 90\u00b0 antepulsion \u2018prayer\u2019 position, allows quantitative bilateral analysis of both arterial (A-PPG) and venous (V-PPG) results. We aimed at determining the proportion of isolated arterial compression with photo-plethysmography in TOS-suspected patients. <jats:italic>Approach.<\/jats:italic> We studied 116 subjects recruited over 4 months (43.3 \u00b1 11.8 years old, 69% females). Fingertip A-PPG and forearm V-PPG were recorded on both sides at 125 Hz and 4 Hz respectively. A-PPG was converted to PPG amplitude and expressed as percentage of resting amplitude (% rest). V-PPG was expressed as percentage of the maximal value (% max) observed during the \u2018Surrender-Prayer\u2019 maneuver. Impairment of arterial inflow during the surrender (As+) or prayer (Ap+) phases were defined as a pulse-amplitude either &lt;5% rest, or &lt;25% rest. Incomplete venous emptying during the surrender (Vs+) or prayer (Vp+) phases were defined as V-PPG values either &lt;70% max, or &lt;87% max. <jats:italic>Main results.<\/jats:italic> Of the 16 possible associations of encodings, As \u2212 Vs \u2212 Ap \u2212 Vp\u2212 was the most frequent observation assumed to be a normal response. Isolated arterial inflow without venous outflow (As + Vs\u2212) impairment in the surrender position was observed in 10.3% (95%CI: 6.7%\u201315.0%) to 15.1% (95%CI: 10.7%\u201320.4%) of limbs. <jats:italic>Significance.<\/jats:italic> Simultaneous A-PPG and V-PPG can discriminate arterial from venous compression and then potentially inter-scalene from other levels of compressions. As such, it opens new perspectives in evaluation and treatment of TOS.<\/jats:p>","DOI":"10.1088\/1361-6579\/ad65b1","type":"journal-article","created":{"date-parts":[[2024,7,19]],"date-time":"2024-07-19T20:12:16Z","timestamp":1721419936000},"page":"085002","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Estimation of the prevalence of isolated inter-scalene compression from simultaneous arterial and venous photoplethysmography in patients referred for suspected thoracic outlet syndrome"],"prefix":"10.1088","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3609-956X","authenticated-orcid":true,"given":"Simon","family":"Lecoq","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeanne","family":"Hersant","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7053-2801","authenticated-orcid":true,"given":"Pierre","family":"Abraham","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,8,2]]},"reference":[{"key":"pmeaad65b1bib1","doi-asserted-by":"publisher","first-page":"11","DOI":"10.3390\/diagnostics8010011","article-title":"A prospective evaluation of duplex ultrasound for thoracic outlet syndrome in high-performance musicians playing bowed string instruments","volume":"8","author":"Adam","year":"2018","journal-title":"Diagnostics"},{"key":"pmeaad65b1bib2","doi-asserted-by":"publisher","first-page":"1324","DOI":"10.1016\/j.jtcvs.2018.05.035","article-title":"Who should be \u201clet in\u201d when managing the thoracic outlet?","volume":"156","author":"Ahmad","year":"2018","journal-title":"J.
