前臂和上臂AVF的目标流量值分别超过720 mL/min和1120 mL/min。 【Ref:Spiliopoulos S, Filippou P, Giannikouris IE, et al. US Volume Flow Assessment to Optimize Angioplasty of Dysfunctional Dialysis Access: The VOLA-II Multicenter Study. ...
1、Assessment of the New AVF for Maturity2Fistula Maturation Definition: Process by which a fistula becomes suitable for cannulation (ie, develops adequate flow, wall thickness, and diameter) Rule of 6s: In general, a mature fistula should: Be a minimum of 6 mm in diameter with discernible ...
All patients underwent a thorough examination, Qa assessment and ECHO-CG with tissue Doppler on the interdialytic day immediately prior to surgery. Qa reduction was achieved by external PTFE banding, PTFE graft segment placement or aneurysmorrhaphy (in case of coexisting AVF aneurysm). Long-term ...
Functional patency was the interval of time from the first 2-needle dialysis utilizing the access until access circuit abandonment. As such, functional patency excludes patients who, for whatever reason, never had two-needle cannulation. Continuous variables are expressed as mean ± standard deviation...
When the arterialized vein segment was considered too deep for successful cannulation at the dialysis center, the patient was referred to an access surgeon and standard surgical techniques of superficialization and elevation was performed. Maintenance interventions were those performed when the endoAVF, ...
The findings were confirmed in a sensitivity analysis that included adjustments for unplanned onset of dialysis and competing risks survival analysis (death—outcome of interest, conversion of HD to PD or kidney transplantation and conversion of AVF to CVC—competing events). According to our results...
Vein injuries were classified based on duplex assessment: Class O-no injury; class 1-intimal flaps; class 2-wall hematoma; class 3-vein rupture. All patients had post-BAM duplex scans in a week. Results All cases but one (99%) were successful. No injuries were seen in 44 cases (38%)...
For these reasons VLPD + KA could be useful in delaying haemodialysis start in late referral ESRD patients who have created AVF, without emergency placement of a central venous catheter.Taurisano MarcoBarbarini SilviaProtopapa PaoloNapoli MarcelloNephrology Dialysis Transplantation...
Haemodialysis through LTVA is preferable in ESRD patients because of the shorter duration of dialysis. We aim to compare the outcome of PAVF to DAVF. Primary endpoint is patency. Secondary endpoints are complication rates, secondary intervention and mortality. 179 patients with ESRD had 200 AVF ...
