Abstract: 【Abstract】Objective To investigate the current status of long-term vascular access in maintenance hemodialysis (MHD) patients in Deyang area. Method A cross-sectional survey was conducted to investigate the long-term vascular access of 1,550 MHD patients from 14 hemodialysis centers in Deyang area in the period from June 1 to June 30, 2018. Their basic information and vascular access methods were recruited. Results This study enrolled a total of 1,550 MHD patients including 1,405 cases of arteriovenous fistula (AVF,90.65%), 136 cases of tunneled cuffed catheter (8.77%) and 9 cases of arteriovenous graft (0.58%). The average service time ofAVF, tunneled cuffed catheter and arteriovenous graft were 46.27±36.11 months, 28.69±21.32
months and 27.99±15.27 months respectively. The blood flow of most vascular access was in the range of 200～300ml/min. AVF located left side in 1,019 patients (72.53%) and located right side in 386 patients (27.47%). The most common type of AVF was wrist radio-cephalic fistula (97.51%) and end-to-side anastomosis (98.08%). Conclusion AVF was the most common long- term vascular access among MHD patients in Deyang area. We should make effort to lower the proportion of patients using central venous catheter for blood access. The application of arteriovenous graft can reduce the use of central venous catheter.
