Hiperfonksiyonel Arteriovenöz Fistülde Kan Akışını Azaltmak İçin Bantlama Yöntemi

Abstract

Objective: Ischemic steal syndrome is a critical complication of arteriovenous (AV) fistula for haemodialysis access that can result in limb loss. Prolonged digital or distal ischemia should be prevented with surgical revascularization. In the current study, we sought to investigate outcomes of the Venocuff banding method for such patients.
 Method: Twenty-two patients with haemodialysis access related ischemia complaints were included in this study. The Venocuff banding method was applied to reduce blood flow in the hyperfunctioning AV fistula. Demographical and postoperative findings were recorded early in the first week and six months after the operation. 
 Findings: There were 16 (73%) male patients and an average age of 64.6 ± 27.3 years. The most commonly accompanying diseases were found to be diabetes mellitus (n:20/90%) and hypertension (n:22/100%). There were 12 (54%) radiocephalic AV fistulas. Preoperative and postoperative Vmax values were found to be -21.3 ± -9.1 cm/s and 24.64 ± 10.45 cm/s, respectively (p = 0.000). Ischemic complaints and findings regressed in the early postoperative period for all patients.
 Conclusion: The banding method using Venocuff seems to be effective for reducing blood flow in hyperfunctioning AV fistula and ameliorating ischemic complaints.
