Background: To analyze the risk factors of a peripherally inserted central catheter (PICC)-related venous thrombosis in patients with breast cancer undergoing chemotherapy and explore its preventive measures.
Methods: Data of 780 patients with breast cancer who underwent PICC chemotherapy in our hospital from January 2014 to June 2015 were retrospectively analyzed. The incidence of catheter-related thrombosis was observed, and related factors of venous thrombosis were analyzed.
Results: Among the 780 patients with breast cancer, 36 developed PICC-related venous thrombosis. The incidence of which was 4.62% (36/780). The PICC retention time ranged between 60 and 136 days, and the median time was 92 days. Thrombosis was found to occur within seven days after catheterization in three patients (8.33%), between 7 and 30 days in 18 patients (50%), between 31 and 92 days in 12 patients (33.3%), and ≥92 days in three patients (8.33%). Basilic vein puncture-induced thrombosis occurred in 25 patients (3.68%), and median cubital vein and cephalic vein puncture-induced thrombosis occurred in 11 patients (10.78%). The difference was statistically significant (P = 0.001). Thrombosis was not associated with age, punctured limb, platelet count, or chemotherapy drugs (P > 0.05).
Conclusion: Blood vessel puncture was the main factor that affected PICC-related thrombosis in breast cancer chemotherapy. The basilic vein should be the primary choice for blood vessel puncture. Prolonged catheter retention does not increase the risk of thrombosis.
