肩胛背神经卡压（不典型胸廓出口综合征）

Dorsal scapular nerve compression── atypical thoracic outlet syndrome.

报告１０例２０侧肩胛背神经和胸长神经的解剖学研究及３４例肩胛背神经卡压的临床病例。解剖观察发现肩胛背神经的起始段常和胸长神经合干，由前内侧向后外侧从中斜角肌中穿过，此处常有腱性组织，和胸长神经分开后，有分支走向肩部和腋下，并可再发分支加入胸长神经。肩胛背神经起始部卡压在临床上可引起颈肩背部的不适和酸痛，手术治疗时观察到切断前中斜角肌后可使肩胛背神经的压迫得到缓解或解除，要彻底减压需切断肩胛背神经浅层的全部中斜角肌及其腱性组织。２２例患者作２４侧手术治疗，１９例患者２０侧完全或大部分解除了症状。

Abstract The paper reports the anatomical study of dorsal scapularnerve and long thoracic nerve in 10 adavers (20 sides ) andclinical study of dorsal scapular nerve compression in 34cases. It was observed that the dorsal scapular nerve and longthoracic nerve often begin from the common trunk.the formerpass through the middle scalenus muscle posteric- exteriorlywhere tendinous tissue was often found. The branches of dorsal scapular nerve went to the shoulder. the axille, and someof them might join the long thoracic nerve after separatingfrom it. The compression at the beginning of this nerve cancause discomfort in neck, shoulder and back region. Completedecompression can be achieved by severing anterior and middlescalenus including tendinous tissue. 22 patients were treatedsurgerically including 24 sides. The symptoms completely ormostly disappeared in19 pases 20 sides.
