RESUMO
Objective To explore the safety,technical feasibility,and catheter-related complications of ultrasound-guided implantation of totally implantable access port (TIAP) in the upper arm.Methods A total of 642 patients,who were admitted to authors' hospital during the period from February 2014 to December 2016 to receive ultrasound-guided implantation of TIAP in the upper arm,were enrolled in this study.The patients included 407 males (63.4％) and 235 females (36.6％),their age ranged from 11 to 89 years old,with a mean age of (58.29±4.33) years old.Under ultrasound guidance,by using Seldinger's technique TIAP was implanted in the upper arm.Results Implantation of TIAP in the upper arm was performed in all 642 patients.The initial success rate of implantation was 99.53％ (639/642),in 3 patients successful implantation was obtained in the second time of implantation as the initial puncturing failed.During the follow-up of 155,302 catheter days,complications occurred in a total of 58 patients (9.0％),including early complications in 9 patients and late complications in 49 patients.The complications included TIAP-related infection (n=28,4.4％),venous thrombosis (n=7,1.1％),sac bleeding (n=3,0.4％),port hub rotation (n=3,0.4％),cracked skin (n=l,0.2％),catheter obstruction (n=2,0.3％),catheter displacement (n=4,0.6％),movement restriction of catheter-side upper limb (n=7,1.1％),venous return obstruction of upper limb (n=2,0.3％) and median nerve injury (n=l,0.2％).No port-related death occurred.Conclusion The ultrasoundguided implantation of TIAP in the upper arm is technically-safe,clinically-effective and minimally-invasive,besides,it carries lower incidence of complications.Therefore,this method is worthy of clinical popularization and application.
