Abstract:
Objective To investigate the incidence and occurrence time of PICC-related upper extremity asymptomatic and symptomatic venous thrombosis in cancer patients;to explore the risk of asymptomatic venous thrombosis' developing into symptomatic venous thrombosis.Methods A total of 246 cancer patients who were scheduled to receive PICC between April and October 2014 were prospectively studied and divided into 2 groups by random digits table method.The time-phased follow-up observation on PICC cathertering cancer patients was conducted by Doppler ultrasound.The follow-up visiting inspection on the cathering upper limb vein by Doppler ultrasound at the 2nd,7th,14th,21st,28th,35th,42nd day were arranged after insertion of the catheter in experimental group (127 cases) to understand the incidence and occurrence time of asymptomatic venous thrombosis,while the control group (119 cases) were investigated for inspecting whether there were venous thrombosis through clinical symptoms or not.Once the clinical symptoms occurred,the incidence and time of occurrence of symptomatic venous thrombosis would be diagnosed by Doppler ultrasound and recorded.Results The incidence rate of asymptomatic thrombosis in the experimental group was 48.82％(62/127),the median time was 3 days,and there was no symptomatic thrombosis.Among them,85.48％(53/62) of the asymptomatic thrombosis occurred within 1 week,11.29％ (7/62) occurred in 2-3 weeks,and 3.23％ (2/62) occurred in 4-6 weeks after catheter insertion.Meanwhile,the incidence and median time of symptomatic thrombosis was 23.53％(28/119) and 12 days respectively in the control group.And 32.14％ (9/28) of these cases occurred within 1 week,50.00％ (14/28) occurred in 2-3 weeks,and 17.86％ (5/28) occurred in 4-6 weeks after catheter insertion.Conclusions The incidence of PICC-related upper extremity venous thrombosis in cancer patients is relatively high,and most cases have no symptoms and occur in an early time.Cancer patients are high-risk patients of venous thrombus.We should take early preventive intervention and treatment to reduce the incidence of venous thrombosis after catheter insertion.
