Rare Variant of the Radial Artery Causing Compression of the Superficial Radial Nerve: A Case Report.

Case: This case report describes a patient with paresthesia in the distribution of the superficial sensory branch of the radial nerve that was treated with surgery. Intraoperatively, there was a unique cause of internal compression by a rare superficial radial artery variant running adjacent to it. The nerve was mobilized from the artery with fascial releases. The patient had symptom resolution postoperatively.
Conclusion: To our knowledge, this cause of compression has not been described before and should be considered in a differential diagnosis. In addition, clinicians should be aware of this anatomical variant during venipunctures and surgical approaches.
