Summary
A supracondylar spur compressing the brachial artery caused upper limb ischemia in a young woman. Surgical removal of the spur and anomalous muscle insertion resolved symptoms, highlighting brachial artery entrapment syndrome as a diagnosis.
Area of Science:
- Vascular Surgery
- Anatomy
- Orthopedics
Background:
- Thoracic outlet syndrome (TOS) can present with atypical arterial symptoms.
- Brachial artery entrapment syndrome (BAES) is a rare cause of upper limb ischemia.
Observation:
- A 25-year-old woman experienced upper limb ischemia during hyperextension.
- Imaging revealed a supracondylar spur compressing the brachial artery.
- An anomalous insertion of the pronator teres muscle was also identified.
Findings:
- Surgical resection of the supracondylar spur and the anomalous pronator teres muscle insertion.
- Immediate and complete relief of ischemic symptoms post-operatively.
Implications:
- BAES should be considered in the differential diagnosis of atypical arterial TOS.
- Anatomical variations can lead to significant vascular compromise.
- Surgical intervention is effective for symptomatic BAES.
