Surgical approach through the anterior scalene muscle resection for invasive tumours in the supraclavicular fossa (with video)

Abstract Background The supraclavicular fossa contains many vital organs to be preserved, such as the brachial plexus, subclavian artery and vertebral artery. Various surgical methods have been reported. However, no well-standardized surgical procedure has been established. Methods Between 2010 and...

Description
Summary:Abstract Background The supraclavicular fossa contains many vital organs to be preserved, such as the brachial plexus, subclavian artery and vertebral artery. Various surgical methods have been reported. However, no well-standardized surgical procedure has been established. Methods Between 2010 and 2020, we performed 28 surgical treatments of the superior mediastinum and supraclavicular fossa. Of these, we retrospectively reviewed seven cases of supraclavicular invasion using a unified surgical technique in which the anterior scalene muscle was resected, and the inter-scalene triangle was approached. Results We performed claviculectomy in four cases and a transmanubrial approach in three cases. In all cases, by resecting the anterior scalene muscle, the brachial plexus, subclavian artery and vertebral artery were preserved. There were no critical postoperative complications other than tracheostomy and lymphatic leakage. Median bleeding amount and operative time were 438 (range; 76–1144) ml and 328 (range; 246–615) minutes, respectively. Conclusions The anterior scalene muscle resection method might be a safe and standardized method for preserving the brachial plexus, subclavian artery and vertebral artery. By resecting the anterior scalene muscle, we clearly identify the important anatomy of the supraclavicular fossa.
