外周血管应用化疗已经不适应肿瘤患者反复住院、多次化疗以及晚期患者对静脉营养支持的需要。外周血管位置表浅、管径细小、血流速度缓慢，化疗药物反复多次经外周给药及化疗药物长时间停留局部刺激血管壁，使得管壁变硬、弹性差，血管及周围组织出现炎性疼痛甚至坏死。血管颜色发黑呈条索状阴影。血管周围皮肤颜色变深，这种损伤恢复慢，容易影响和延误治疗。因此，近几年来，深静脉置管广泛应用于肿瘤化疗给药。常用的深静脉有锁骨下静脉、颈内外静脉、PICC经上腔静脉给药和股静脉置管从下腔静脉给药。股静脉管腔大，血流快，可以迅速将化疗药物带入血液循环，对血管损伤小。“,”Peripheral arterial chemotherapy has not adapted to the tumor patientshospitalized for many times repeatedly,chemotherapy and parenteral nutrition support in patients with advanced to the needs of.Peripheral vascular superficial location,smal diameter,blood flow speed is slow,the chemotherapy drug repeatedly after peripheral administration of chemotherapeutic drugs and long time stay local stimulation of vascular wal ,which makes the tube wal hardens,poor elasticity,blood vessels and sur ounding tissue with inflammatory pain and even necrosis.Vascular color black like trabs shadow.Around blood vessels in the skin become darker in color,this kind of injury to restoreslower,easy to influence and delay treatment,increase the suf ering of patients.Therefore,in recent years,deep vein pipe widely used in cancer chemotherapy drug.Commonly used deep vein subclavian vein,internal and external carotid vein,PICC through the superior vena cava to medicine and femoral vein puncture from inferior vena cava tomedicine.Femoral vein lumen,blood flow faster,you can quickly turn chemotherapy drugsinto the blood,smal injury to blood vessels.
