The relationship between the origin of anterior and middle scalene muscle and the upper trunk of brachiplex

前、中斜角肌起点与臂丛上干的关系及其临床意义

Objective To establish a method of subclavian vein puncture and catheterization through the gap between clavicle and anterior scalene muscle .

目的探讨前斜角肌？锁骨间隙入路行锁骨下静脉穿刺置管的可行性及其特点。

Conclusions : The contraction of the posterior components of the anterior and middle scalene muscle may be the main reason of the upper trunk thoracic outlet syndrome .

结论：前中斜角肌在颈椎横突的前、后结节均有起点，该交叉起点是上干型胸廓出口综合征的主要病因。

Method Anatomical study was made on both sides of 30 cadavers . The minimus scalene muscle and the insertions of anterior and middle scalene muscle were dissected and observed .

方法对30具60侧经福尔马林固定的成人尸体小斜角肌及前中斜角肌的起始部进行解剖研究；

Results : Anterior scalene muscle originates from transverse processes of 3 ~ 6 cervical vertebrae . Middle scalene muscle starts from transverse processes of 2 ~ 7 or 2 ~ 6 cervical vertebrae .

结果：前斜角肌起于第3～6颈椎横突的前后结节，中斜角肌起于第2～7或2-6颈椎横突的前后结节。

Of the recent 8 cases of TOS , 7 presented neck shoulder pain . However , the symptom remained in only case after the resection of the tendinous tissue around 5,6 nerve root from anterior and middle scalene muscle .

8例1996～1997年手术者中，7例有颈肩痛，术中切断前中斜角肌在C5～6神经根旁的腱性纤维组织，术后仅有1例仍有颈肩部不适。

While neurilemmoma of the brachial plexus lies below the carotid bifurcation , and posterior or posterolateral to the anterior scalene muscle . The transverse cervical artery which crosses the anterior scalene muscle covers the part of the tumor and lies superficially .

而臂丛神经鞘瘤位于颈动脉分叉水平以下，紧贴前斜角肌后或后外方，颈横动脉横跨前斜角肌表面向肿瘤未被肌肉覆盖部分的浅面走行。

Scan by CT , measuring cross section and CT value of scalene anterior muscle , as normal contrast ;

CT平扫其C6上缘-C7上缘，测量前斜角肌横断面面积及CT值，统计后作为正常值参照；

Result : The scalene minimus muscle was found in 33 patients with TOS . According to the criteria by Roos and Wood , the excellent and good was 78.8 % .

结果：术中探查33例下干型TOS中均有小斜角肌的存在，术后优良率为788%。

Objective : 1 Measured and statisticsed areas of cross section and CT value of scalene anterior muscle on plan from superior border of C6 to C7 , as a objective basement of this topic and other correspond research ;

目的：1测定C6上缘-C7上缘水平前斜角肌模断面面积及CT值的正常值，作为本课题及相关研究的客观依据；
