Background: Systemic cytokines are elevated in chronic kidney disease (CKD) and hemodialysis patients compared to the general population. However, whether cytokine levels interfere with vascular remodeling increasing the risk of arteriovenous fistula (AVF) failure remains unknown. Methods: This is a case-control study of 64 patients who underwent surgery for AVF creation (32 with AVF maturation failure and 32 matching controls with successful maturation). A total of 74 cytokines, including chemokines, interferons, interleukins, and growth factors, were measured in preoperative plasma samples using multiplex assays. Sixty-two patients were included in the statistical analyses. Associations with AVF failure were assessed using paired comparisons and conditional logistic regressions accounting for paired strata. Results: Seven cytokines were significantly higher in patients with AVF maturation failure than in matching controls (G-CSF, IL-6, MDC, RANTES, SDF-1α/β, TGFα, and TPO). Of these, G-CSF (odds ratio 1.71 [1.05-2.79] per 10 pg/mL), MDC (1.60 [1.08-2.38] per 100 pg/mL), RANTES (1.55 [1.10-2.17] per 100 pg/mL), SDF-1α/β (1.18 [1.04-1.33] per 1000 pg/mL), and TGFα (OR 1.39 [1.003-1.92] per 1 pg/mL) showed an incremental association by logistic regression. Conclusions: This study identified a profile of plasma cytokines associated with adverse maturation outcomes in AVFs. These findings may open the doors for future therapeutics and markers for risk stratification.

Vascular access thrombosis is an important complication with great impact on access patency and, consequently, on a patient’s quality of life and survival. We report the case of a 73-year-old woman with chronic kidney disease on hemodialysis with a radiocephalic arteriovenous fistula on the right arm that was brought to the emergency department with decreased strength in her right arm, ipsilateral hypoesthesia and facial hemi-hypoesthesia. The patient was given a brain computed tomographic scan that did not confirm suspicion of stroke. On re-examination, the patient had new-onset pain at arteriovenous fistula level, and her right arm was cold and pale. The nephrology department was called for arteriovenous fistula evaluation. On physical examination, her forearm fistula had a decreased thrill and arm elevation exacerbated its paleness. A bedside ultrasound was performed for arteriovenous fistula assessment. Doppler ultrasound revealed: partial thrombosis at brachial bifurcation, a flow of 80–105 mL/min at brachial artery level and a radial artery with a damped waveform. Anastomosis and draining vein were permeable. In this case, the diagnosis of acute embolic brachial artery occlusion was made by a fast bedside ultrasound evaluation. The patient underwent thromboembolectomy with Fogarty technique, recovering fistula thrill, radial and cubital pulses. Thromboembolism of the fistula feeding artery is a rare cause of vascular access thrombosis and it is rarely mentioned in the literature. In this report, failure to recognize the upper limb ischemia would have led to delayed treatment, potentially resulting in the fistula’s complete thrombosis and further limb ischemia. We highlight the importance of a diagnosis method like Doppler ultrasound, which allows for rapid evaluation at the patient’s bedside.

Maintaining a good quality vascular access in the long term can become particularly challenging especially in patients that are on dialysis for many years and present with exhausted venous capital and chronic access related complications. We present a 60-year-old female patient with multiple bilateral previous failed accesses, a previous distal revascularization interval ligation (DRIL) for hemodialysis access induced distal ischemia (HAIDI). Her chronically (more than a month) occluded arteriovenous fistula AVF was used to establish outflow and create a functioning forearm arteriovenous graft (AVG).

Abstract Background Spinal dural arteriovenous fistula (SDAVF) usually occurs during the 4th to 6th decades of life, and adolescent SDAVF is rarely reported. SDAVF arising around a tumor is also rare, and reported tumors are mostly schwannoma and lipoma. Case presentation We reported a 16-year-old male presented with progressive weakness and numbness of lower limbs for 3 months. A SDAVF was found, which was fed by right radicular arteries from segmental artery at L2 level and drained retrogradely into perimedullary veins. A concomitant spinal extradural nodular fasciitis at right L1/L2 intervertebral foramen was also noted. The SDAVF was completely obliterated by endovascular treatment and the tumor was debulked. The patient recovered well after the procedures. Conclusions Our case report suggests SDAVF can occur in adolescent. The concomitant presence with a nodular fasciitis indicates that although it usually arises in subcutaneous tissue but can rarely form on the dura of spine.

Rudolph Matas (1860-1957) was one of the foremost figures in the history of vascular surgery. He is considered the father of vascular surgery for his operations for arteriovenous fistula and peripheral artery aneurysm, all devised before the isolation of heparin and the wide adoption of techniques for vascular anastomosis. A medical and surgical prodigy, Matas received his medical degree from Tulane University at age 19 (1880) and was named its chair of surgery at 35 (1895), a position he would hold until 1927. A contemporary and friend of Halsted, Matas throughout his career he was known as a leader in the field, holding the presidencies of the American College of Surgeons (1925-1926) and the American Surgical Association (1909). He maintained loyal relationships to those who trained in surgery with him at Touro Hospital in New Orleans, including the author’s grandfather, the first Richard J. Field. Matas was an honored guest at the dedication of the Centreville Clinic in 1928, the facility where three generations of Field surgeons have provided continuous service to its rural Mississippi community for nearly a century.
