近年来癌症的发病率明显上升~([1]),成为威胁人类健康的首要因素。静脉化疗是恶性肿瘤患者主要的治疗手段之一,由于经外周静脉输注化疗药物导致患者血管的损害,往往影响患者下一周期的治疗~([2])。PICC不仅避免了化疗药物对血管的破坏,而且减少了肿瘤化疗患者反复穿刺的痛苦,在肿瘤化疗中发挥了重要的作用。PICC具有手术操作简单、穿刺成功率高,留置时间长等优点,被越来越多的肿瘤患者及家属接受。但PICC作为一种侵入性的操作,可
In recent years, the incidence of cancer has risen significantly ([1]), becoming the primary factor threatening human health. Intravenous chemotherapy is one of the main treatments in patients with malignant tumors. The damage to the blood vessels caused by peripheral intravenous chemotherapy drugs often affects the treatment of patients in the next cycle ~ ([2]).

PICC has the advantages of simple operation, high puncture success rate and long retention time, which is accepted by more and more cancer patients and their families. But PICC as an invasive operation, can
