Abstract

Purpose: The aim of this study was to evaluate flow volume and anastomosis diameter of native arteriovenous fistulas(AVF). Materials and Methods: 16 patients with native AVF were evaluated using Doppler Ultrasound. Eleven of 16 patients had upper arm AVF (bachiocephalic or brachiobasillic) and 5 of 16 patinets had forearm AVF (radiocephalic). Twelve of 16 patients had not symptoms. There was edema of upper extremity in 4 patients. Brachial artery flow volume and AVF anastomosis diameter were calculated using Doppler ultrasound. Fistulography was performed on 3 of the 4 patients who had upper extremity edema. Results: The brachial artery flow volume was calculated to be less than 2000ml/min in 14 of the 16 patients. The mean AVF anastomosis diameter was 3.6 mm in these patients. Whose flow volume of brachial artery were 4400ml/min and 6000ml/min. The diameters of AVF anastomosis were 6.9 mm and 10 mm in the 2 patients. Whose fistulography showed subclavian vein thrombosis in 2 patients and subclavian vein stenosis in 1 patient. Conclusion: In this study, diameter of AVF anastomosis with high flow volume was greater than diameter of AVF anastomosis with normal flow volume. Increased diameter of AVF anastomosis may be responsible for an increased flow volume of AVF.

Özet

Amaç: Nativ hemodiyaliz arteriyovenöz fıstüllü (AVF) hastalarda brakiyal arter akım volümü ile AVF anastomoz çapı arasındaki ilişkiyi araştırmak. Gereç ve Yöntem: Toplam 16 nativ AVF'li hasta değerlendirildi.16 hastanın ll'inde AVFüst kolda (brakiyobazilik ya da brakiyosefalik) 5'inde ise ön kolda (radiyosefalik) yer almaktaydı. Ortalama AVF süresi 24 aydı. 16 hastanın 12'si semptomsuzdu. 4 hastada ise üst ekstremitede ödem mevcuttu. Doppler ultrasonografı ile AVF' lerde brakiyal arter akım volümü ve AVF anastomoz genişliği ölçüldü. Üst ekstremitede ödem bulunan 4 hastanın 3'üne fisrülografı yapılarak ödem etiyolojisi araştırıldı. Bulgular: 16 hastanın 14'ünde brakiyal arter volümü 2000ml/dk altında ölçüldü. Bu hastalarda AVF anastomoz genişliği ortalama 3.6 mm idi. Brakiyal arter akım volümü 2000ml/dk üzerinde ölçüleri 2 hastada (4400ml/dk, 6000ml/dk) AVF anastomoz genişliği sırasıyla 6.9mm ve l Omni idi. Fisrülografı yapılan 3 hastanın 2'sinde sunklavyan vende tromboz, l 'inde darlık saptandı. Sonuç: Doppler ultrasonografı ile AVF'lerde akım volümü hesaplanabilir. Bizim çalışmamızda, yüksek akım volümüne sahip AVF'lerde anastomoz genişliği normal volümlü hastalara göre daha fazla idi. Artmış anastomoz genişliği yüksek akım volümünün sebebi olabilir.
