- W4308606469 abstract "Doppler ultrasonography is the main modality for imaging of hemodialysis AV stula as it is safe and non-invasive. This study is to measure the Arterio-venous (AV) stula blood ow during early postoperative period (0–7days) and assess its role in AV stula failure prediction. Doppler ultrasonography was used to estimate the blood ow in the AV stula of 50 patients at (0–7days) after the stula was made. The blood ow in stula during early postoperative period for stula failure was evaluated, and long term failure was predicted. Method Blood ow rates measured in arteriovenous stula created in upper extremity were measured in rst week and sixth week post-operative. Results After follow up evaluation out of 50 patients, 40 stulas considered to be matured; 10 considered failed. 30% failure were males and 70% were female. In early post operative period, cut off was set at 182 ml/min and the sensitivity of blood ow for prediction of stula failure is 98%, specicity 90 %, PPV 95% and NPV 90%. Conclusion Measurements of the AV stula blood ow in proximal artery and draining vein with its diameter of lumen were noted in the early postoperative period has a role predicting AV stula failure. There is risk of failure if the blood ow less than 182 ml/min (day 0–7)." @default.
