Abstract:
Objective To investigate the clinical application of percutaneous transluminal angioplasty(PTA)in treating dysfunctional central vein caused by tunnel-cuffed catheter(TCC)under digital subtraction angiography(DS A)guidance.Methods A total of 13 patients with indwelling TCC-related central vein complications,who were admitted to the Department of Nephrology of the Affiliated Hospital of Qingdao University of China between July 2018 and July 2022,were enrolled in this study.The average indwelling duration of TCC was 35.2 months(range of 6-70 months).The dysfunctional TCC was removed with the help of a stiff guide wire,and angiography showed that the central vein was narrowed or occluded.PT A was performed to reopen the central vein,and a new TCC was placed in situ or in another site.Results Of the 13 patients,original TCC was successfully removed in 12,and failure of removal was seen in one.The site of central venous stenosis included the right jugular vein,innominate vein,superior vena cava,and right iliac vein,and successful placement of a new TCC was accomplished in all patients after PTA,and no stent implantation was employed.The average follow-up period was 23.1 months(range of 6-48 months),and the TCC functioned well.Conclusion Under DSA guidance,the recanalization of TCC-related central venous stenosis or occlusion by PT A and the implantation of a new TCC catheter can successfully establish a new dialysis access for patients with poorly functioning TCC,in this way the lifespan of the pathway can be extended.
