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.
