FEWER HERO GRAFTS & MORE THIGH FISTULAS
Conclusions Our Practice has made a significant shift from HeRO grafts to SFA-tFV thigh fistulas as our first choice for patients with bilateral central venous stenosis. There has been a significant learning curve for the SFA-tFV thigh fistula Longer follow up needed for proper comparison between the techniques
