经皮锁骨下动脉（ＳＣＡ）穿刺是导管药盒系统植入术的难点之一。对１２例成人尸体标本双侧ＳＣＡ走行及毗临关系解剖学观察表明，ＳＣＡ的体表投影点（Ｄ点）位于胸锁关节与喙突连线中点偏外约１ｃｍ处。当动脉的穿刺靶点为Ｄ点内１．５ｃｍ上约１ｃｍ处时，在锁骨中外１／３下２～３ｃｍ处进针，角度额状面为（２０～３０）°，横断面为（１０～２０）°，深度为４～５ｃｍ。２０例患者穿刺成功并送入导丝后的Ｘ线照片测量显示左ＳＣＡ位于第一肋外缘中点处，可作为透视下定位点和靶点。ＳＣＡ穿刺先按体表标志进行，困难时按透视下骨性标志进行，不成功则采取经股动脉插管，入左ＳＣＡ，透视引导下穿刺。
Transcutaneous subclavian artery (SCA) puncture catheter system is one of the difficulties of implant system. Anatomical observation of bilateral SCA travel and Pien-Lin relationship in 12 adult cadaver specimens showed that the body surface projection point (D point) of SCA was located about 1cm outside midpoint of the sternoclavicular joint and coracoid process. When the target of artery puncture is about 1cm at 1.5cm in point D, the needle is inserted at 2 ~ 3cm away from the middle and the outer 1/3 of the clavicle, the angle of frontal plane is (20-30) ° and the cross section is (10 ~ 20) °, the depth of 4 ~ 5cm. The radiographs of 20 patients who had been successfully punctured and delivered to the guidewire showed that the left SCA was located at the midpoint of the outer edge of the first rib and could serve as a site of fixation and target under fluoroscopy. SCA puncture according to the first body surface markers, difficult under the perspective of the bony signs under fluoroscopy, unsuccessful to take the femoral artery catheterization into the left SCA, under the guidance of fluoroscopy puncture.
