Pediatric thoracic outlet syndrome: a systematic review with metadata

Thoracic outlet syndrome (TOS) typically considered a condition of the adult population; it is often disregarded in children and adolescents due to its limited recognition within the pediatrics. The current study aims to systematically review and provide insights into TOS among pediatric patients.

PubMed, Scopus, Web of Science, and Google Scholar databases were thoroughly searched for English language studies published until March 15th, 2024. The study included those articles focusing on pediatric or adolescent individuals diagnosed with TOS. Data collected from studies encompassed date of publication, number of participants or reported cases, age (years), gender of participants, type of TOS, affected side, type of treatment, surgical approach, bony abnormality, duration of symptoms (months), outcome, and follow-up time duration (months).

The current study comprised 33 articles, 21 of which were case reports, 10 of which were case series, and the remaining were cohort studies. In this study, 356 patients were included. Females constituted 234 (65.73%) of the patient population. Among TOS types, neurogenic TOS was found among 201 (56.5%) patients. Sporting-related activity or physical activity was present in 193 (54%) patients, followed by a history of trauma in 27 (7%) patients.

Pediatric patients exhibited a higher percentage of vascular TOS than their adult counterparts, with the supraclavicular approach emerging as the preferred treatment method. Sports-related activities were identified as the primary risk factor associated with pediatric TOS.
