Abstract

The stenosis at the proximal end of the arteriovenous fistula (AVF) can cause dysfunction and can lead to thrombosis of the vascular access. Performing angioplasty at the antecubital region can repair the proximal stenosis in the forearm AVF. However, it is technically difficult to expose the most proximal part of cephalic vein in upper arm AVF. We present a case who had a brachiocephalic AVF with isolated proximal cephalic vein obstruction without central vein stenosis. The patient was referred to our center for inadequate creatinine clearance even though she continued to have complete hemodialysis with adequate blood withdrawal. The fistulogram demonstrated isolated proximal cephalic vein stenosis at the level of drainage to the central vein. The patient had thrombectomy and the end of cephalic vein was anastamozed to the brachial vein through a new tunnel. There was satisfactory blood flow through the cephalic vein after diversion of blood flow to brachial venous system from occluded cephalic vein. Hemodialysis patients who have recirculation and inadequate clearance at their brachiocephalic arteriovenous fistula should have fistulography to identify isolated cephalic vein stenosis. Venovenostomy at the upper arm to bypass the proximal saphenous stenosis is both technically easy and an effective approach.

Özet

Arteriovenöz fistüllerde proksimal kısımda gelişen darlıklar fonksiyon bozukluğuna sebep olabilir ve damar yolunun tıkanmasıyla sonuçlanabilir. Antekübital bölgede anjioplasti yapılarak önkoldaki arteriovenöz fistüllerdeki proksimal darlıklar onarılabilir. Ancak üst kolda bulunan sefalik venin proksimal kısmına ulaşmak teknik olarak güçtür. Santral venlerde darlığı olmadan izole proksimal sefalik ven darlığı olan bir olguyu sunacağız. Hasta merkezimize yeterli kan çekilerek tam hemodiyaliz yapıldığı halde uygun kretinin klirensi sağlanamadığı için yönlendirildi. Fistülogram tetkiki proksimal sefalik vende santral venlere dökülme noktasında darlık olduğunu gösterdi. Hastaya trombektomi uygulandı ve sefalik ven yeni bir tünelden geçirilerek brakial vene anastamoz edildi. Tıkalı olan sefalik venden brakial venöz sisteme akımın yönlendirilmesi sonrasında brakiosefalik fistülde yeterli akım sağlandı. Brakiosefalik arteriovenöz fistüllerinde resürkilasyon olan ve yeterli klirens sağlanamayan olgularda fistülografi yapılarak izole sefalik ven darlığı tespit edilebilir. Üstkolda venovenostomi yapılarak proksimal sefalik ven darlığında akımın brakial venöz sisteme yönlendirilmesi teknik olarak kolay ve etkili bir yöntemdir.
