A case of hypertrophic anterior scalene muscle surgically treated is reported. The patient suffered from upper limb intermittent claudication at any sustained upper extremity activity such as lifting a weight or opening and closing the hand with the arm abducted. Doppler and angiographic study showed significant compression of subclavian artery with hyperabduction and Adson manoeuver. Simple anterior scalenotomy was followed by prompt recovery of symptoms. The results of scalenotomy and other surgical approaches to thoracic outlet syndrome are reviewed in the literature. The most common anomalies of anterior scalene muscle in the TOS are also described. Doppler and arteriographic study in different functional positions are necessary in the evaluation of subclavian artery compression by osseous or muscular structures.

Abstract

A case of hypertrophic anterior scalene muscle surgically treated is reported. The patient suffered from upper limb intermittent claudication at any sustained upper extremity activity such as lifting a weight or opening and closing the hand with the arm abducted. Doppler and angiographic study showed significant compression of subclavian artery with hyperabduction and Adson manoeuver. Simple anterior scalenotomy was followed by prompt recovery of symptoms. The results of scalenotomy and other surgical approaches to thoracic outlet syndrome are reviewed in the literature. The most common anomalies of anterior scalene muscle in the TOS are also described. Doppler and arteriographic study in different functional positions are necessary in the evaluation of subclavian artery compression by osseous or muscular structures. In the reported case scalenotomy was at least as effective as 1st rib resection
