Skin necrosis overlying an arteriovenous fistula at the cannulation site is a common and potentially life-threatening problem, often associated with underlying aneurysm formation. Arteriovenous fistula-skin necrosis generally requires resection of surrounding skin margins and the underlying aneurysmal vessel wall, allowing repair with healthy tissue of the arteriovenous fistula in addition to closure of soft tissue and skin. In patients with insufficient fistula length, salvage of these arteriovenous fistulas may result in difficult or insurmountable cannulation issues leading to attempts at one-needle cannulation dialysis or, most often, catheter placement. Pre-existing stents or extensive calcification may add to the technical challenge of gaining proximal and/or distal control. We describe our technique for dealing with such arteriovenous fistula-skin necrosis lesions utilizing endo-occlusion with an angioplasty balloon for vascular control, allowing a limited incision and tissue resection with preservation of arteriovenous fistula cannulation length.

Introduction: This study evaluated the mid-term patency of forearm loop arteriovenous grafts and the dilation of previously inadequate upper arm basilic and cephalic veins after failed forearm loop arteriovenous graft. Methods: All access procedures from September 2009 to December 2015 were reviewed. Vein mapping measurements were used to determine whether there was “adequate” upper arm cephalic and/or basilic vein, defined as ⩾3 mm by duplex ultrasound, at the time of forearm loop arteriovenous graft creation. Outcomes of forearm loop arteriovenous graft were compared with upper arm arteriovenous fistula, and primary and cumulative patencies were evaluated. Results: Thirty-eight forearm loop arteriovenous grafts and 278 upper arm arteriovenous fistulas were created. In the forearm loop arteriovenous graft cohort, nine were inserted with adequate upper arm vein, group A, and 29 were inserted with inadequate upper arm vein, group B. Cumulative patency was lower for forearm loop arteriovenous graft compared with upper arm arteriovenous fistula at 6 months, 1 year, and 2 years (67% vs 91%, 61% vs 85%, and 49% vs 80%, respectively, P < .01). Comparison of group A forearm loop arteriovenous graft and upper arm arteriovenous fistula did not show a statistical difference in cumulative patency at 6 months, 1 year, and 2 years (P = .80, .62, and .70, respectively). Of group B with failed forearm loop arteriovenous graft, 36% became candidates for upper arm arteriovenous fistula with dilation of ipsilateral upper arm cephalic or basilic vein to ⩾3 mm. Conclusion: In this study, forearm loop arteriovenous graft with adequate upper arm vein did not show a statistical difference in mid-term patencies compared with upper arm arteriovenous fistula. For those forearm loop arteriovenous grafts with inadequate upper arm vein, approximately one-third of patients became candidates for upper arm arteriovenous fistula demonstrating the benefits forearm loop arteriovenous graft.

The rate of arteriovenous fistula (AVF) placement continues to rise and AVF failure is a major complication. The main cause of AVF failure is stenosis leading to thrombosis. Although the detection of early stenosis with preemptive correction prior to thrombosis seems to be a plausible option to prevent access failure, there is much debate, on the basis of studies of surveillance with arteriovenous grafts, as to whether early surveillance actually improves the longevity of AVFs. Evaluating the available information for surveillance, specifically the data for AVF stenosis and survival, is necessary to determine if surveillance is warranted. These trials have shown that vascular access flow (Qa) surveillance is beneficial in revealing subclinical stenosis. Preemptive angioplasty and surgical revision have shown to decrease thrombosis rates. However, at the present time, there is only limited data on whether preemptive treatment equates to improved long-term AVF survival.

Work Up

Background: Chronic kidney disease (CKD) is a long term condition caused by damage to both kidneys. The benefits of arteriovenous fistulas over other forms of chronic access are: Arteriovenous fistulas are associated with decreased morbidity and mortality among hemodialysis patients compared with arteriovenous grafts and central venous catheters. Objectives of the study were o choose the proper sites for formation of arteriovenous fistula, to find out the success rate at various sites and to study the complications of arteriovenous fistula.Methods: This prospective study was carried out on total 150 patients over the duration of two years. The fistulae were created using radial artery and cephalic vein side to side (Radiocephalic AVF) and brachial artery and cephalic vein side to side anastomosis (Brachiocephalic AVF). Doppler studies were done before and after every procedure to demonstrate the velocity, volume of blood flow, depth from the skin, diameter of vessels and to access the time of maturation of AVF. Patients were followed up to first dialysis by AVF to assess the overall outcomes and various complications.Results: Brachiocephalic AVF matured earlier than Radiocephalic AVF (mean maturation time Brachiocephalic 38.02 days and Radiocephalic 43.26 days) which was statistically significant. Brachiocephalic AVF matured earlier than Radiocephalic AVF with more flow rate. Complication rate was more at wrist (Radiocephalic AVF with 66.67% of overall complication) than at elbow (Brachiocephalic AVF with 33.33% of overall complication).Conclusions: We concluded that the Brachiocephalic AVF maturation time was significantly less than the maturation time of Radiocephalic AVF and rate of complication was less in Brachiocephalic AVF. The utility of pre-operative colour Doppler to select the vessels for AVF creation was found to be as an essential parameter of pre-operative work up.
