Fig. 5From: Role of early postoperative ultrasonography in prediction of AV fistula failure in hemodialysis patientsA 57-year-old male patient with history of hypertensive nephropathy. a Color Doppler US 8 days after the surgery shows blood flow at the anastomosis (volume flow is 140 ml/min). b B mode US demonstrates hematoma related to the AV fistula at the late postoperative period, and it measures (2.6 × 2.7 × 2.7 cm). c Color Doppler US shows the late postoperative period volume flow measurement 144 ml/min, this fistula failed, and the cause of failure was hematomaBack to article page
