Abstract
Background : Native arteriovenous fistula (AVF) is the vascular access of choice for hemodialysis patients. AVF lasts longer than artificial grafts or central venous catheters. In addition, AVF has fewer complications than other vascular accesses. The use of Doppler ultrasound is used to facilitate fistula construction (vascular mapping) including AVF maturation to see if AVF can be used.
 Doppler ultrasound monitoring for maturation of AV fistulas should be monitored sonographically until the fistula is ready for use, especially when maturation is slow and in patients whose veins cannot easily be assessed by physical examination alone (eg because of obesity). The AVF DUS flow volume measurement may be the only imaging tool that can be used to monitor a fistula even during its maturation. Even so, DUS should always be done before AVF is used for the first time. This examination provides baseline data on vascular access, which can be useful in subsequent tests performed to evaluate functional problems.
 Case report : A man, 52 years old who has done AV Fitula two weeks ago. Currently patients are using a double lumen catheter (CDL) for routine hemodialysis. One day the patient had his CDL removed. Even though the patient feels thrill in the AV fistula, the nephrorologist still doubts whether the AV fistula is ripe and can be used. For this reason, a Duplex Ultrasound is performed to assess the diameter, velocity flow, PSV and TAMV .By positioning the sample volume in the presumed stenosis site, the Doppler velocity test detects a systolic peak velocity.
 Conclusion: Color flow Doppler imaging should be used as a tool to screen for areas of high velocity and to aid in the optimal placement of the pulsed Doppler sample volume. The pulsed Doppler sample volume should be set at the smallest size possible to detect discrete changes in blood flow meanwhile doppler ultrasound should be use in monitoring for maturation of AV fistulas
Highlights
The best modality in patients with EndStage Renal Disease (ESRD) grade V is an arteriovenous fistula (AVF) in the hemodialysis process.[1]
There are obstacles in hemodialysis patients because the AV fistula maturation process takes about three months to be ready for use
The duplex ultrasound surveillance (US) shows the diameter of the vein is 0.53 cm with a depth of 0.86 cm with good peak systolic velocity (PSV) and volume flow
Summary
The best modality in patients with EndStage Renal Disease (ESRD) grade V is an arteriovenous fistula (AVF) in the hemodialysis process.[1]. There are obstacles in hemodialysis patients because the AV fistula maturation process takes about three months to be ready for use. This is because of the operation of venous arterialization in the AFVs. This is because of the operation of venous arterialization in the AFVs This case report deals with the literature related to ultrasound surveillance (US) of AVF. A man, 52 years with hypertension, nondiabetic and stage 5 chronic renal failure, has undergone routine HD with CDL access. This patient had AVF creation two months ago.
