Abstract
OBJECTIVE Hemodialysis access induced distal ischemia (HAIDI) is a known complication of hemodialysis (HD) access. Distal revascularization and interval ligation (DRIL) is the preferred treatment for HAIDI by many surgeons. Proximalization of arterial inflow (PAI) is a promising alternative technique that, unlike DRIL, preserves the native arterial inflow. The purpose of this study is to report our experience with PAI on a series of 64 patients. METHODS This is a single-center, retrospective cohort study of patients with both AV fistulas and grafts who underwent PAI for HAIDI from 2017 to 2023. A 4x7 tapered polytetrafluoroethylene (PTFE) graft was used to connect HD access inflow to the axillary artery in the majority of cases. The primary outcome of the study is resolution of HAIDI (complete, partial, or no resolution). Secondary outcomes include functional patency (primary and secondary) and 30-day complications following PAI. RESULTS Of the 71 patients identified to have had PAI between May 2017 to August 2023, seven were lost to follow-up. In total, 64 patients were included, with an average age of 65 years (SD 15), 59.4% (38/64) female, and 37.5% (24/64) African American. The study population was notable for numerous comorbid conditions including 95.3% (61/64) HTN, 50% (32/64) CAD, 79.7% (51/64) diabetes, and 43.8% (28/64) smoking history. Following PAI intervention for HAIDI, 55/64 (85.9%) patients experienced complete resolution of ischemic symptoms, 5/64 (7.8%) patients had partial resolution, 2/64 (3.1%) patients had no resolution, and 2/64 (3.1%) patients had unknown resolution. Primary patency at 1, 12, and 24 months was 94%, 81%, and 71%, respectively. Secondary patency at 1, 12, and 24 months was 97%, 87%, and 84%, respectively. The 30-day complication rate was 10.9% (7/64), with 5/64 (7.8%) thromboses, 1/64 (1.6%) thrombosis and infection, and 1/64 (1.6%) upper extremity swelling secondary to central venous stenosis (resolved with angioplasty of central venous system). Failure rate due to thrombosis at 12 and 24 months was 14% (9/64) and 15.6% (10/64), respectively. CONCLUSIONS Our study, the largest case series of PAI to-date, demonstrates that PAI is a reliable option for HAIDI intervention and has comparable safety and efficacy results to DRIL. Furthermore, PAI has the added benefit of maintaining the native arterial pathway. Further investigation of PAI is warranted as a promising alternative to DRIL for HAIDI management.

Recognizing dialysis access steal syndrome with central vein stenosis as arteriovenous fistula complication: A case report. Int J Surg Case Rep 2022; 102:107824. [PMID: 36493710 PMCID: PMC9730160 DOI: 10.1016/j.ijscr.2022.107824] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/27/2022] [Accepted: 11/28/2022] [Indexed: 12/03/2022] Open
Abstract
INTRODUCTION Ischemic consequences of hemodialysis arteriovenous (AV) access are infrequent, yet they can cause substantial limb impairment or even loss. Ischemia can be caused by many factors, but the most common etiology is reduced blood supply to the distal extremities due to blood flow through the AV fistula (AVF) or AV graft. We reported a case of dialysis access steal syndrome (DASS) in a diabetes mellitus patient. CASE REPORT A 69-year-old diabetic man with left brachiocephalic AVF on his left upper arm has main complaint of left-hand pain, swelling, and coldness. There are also trophic darkening changes in the distal first, third, and fourth fingers. A duplex doppler examination revealed a normal functional AV shunt with bidirectional distal retrograde inflow. There was also significant stenosis at axillary vein. So, a diagnosis of DASS with suspicion of distal anastomosis stenosis at axillary vein was made. The patient underwent digital amputation and surgical plication of the AV shunt. He also underwent percutaneous transluminal angioplasty at the level of axillary. After 10 days of care, he was later discharged. CLINICAL DISCUSSION DASS is life and limb-threatening clinical disorder. Not only does the discomfort make it difficult for the patient to tolerate hemodialysis, but the ischemia can cause tissue necrosis and the eventual loss of fingers and possibly the patient's life. Doppler ultrasonography is a non-invasive technique that provides important information about vascular anatomy and hemodynamics. Aggressive treatment, including limb surgery and intensive blood glucose regulation, will result in favourable results. CONCLUSIONS DASS is a rare condition usually encountered in hemodialysis patients with AVF. Proper diagnosis and management are needed to get an optimal outcome for the patient.

Abstract
Ischemic steal syndrome (ISS) secondary to an arteriovenous fistula (AVF) in the lower extremity (LE) is a rare occurrence. Herein, we report a case of symptomatic ISS in an adult male due to an iatrogenic AVF in the left LE, which was surgically repaired by placing an arterial stent across the acquired AVF of the peroneal artery to the peroneal vein.

Abstract
Introduction: In case of kidney failure, hemodialysis is the primary kidney replacement technique. Several vascular access methods used for the therapy, one of which is the arterio-venous fistula (AVF). In the AVF, the blood flow is altered, which can elevate the mechanical stress on the red blood cells (RBCs). This can affect the RBC hemorheological properties, and it can further cause systemic changes. To lower the turbulence and shear stress, we performed a loop-shaped arterio-arterial venous interposition graft (loop-shaped graft) to compare its effect to the conventional AVF. Materials and Methods: Thirty male Wistar were used (permission registration Nr.: 25/2016/UDCAW). The animals were randomly divided into sham-operated, AVF, and loop groups (n = 10/each). The superficial inferior epigastric vein (SIEV) was used to create the AVF and the loop-shaped graft. Blood samples were taken before/after the surgery and at the 1st, 3rd, and 5th postoperative weeks. We measured hemorhelogical, hematological, and blood gas parameters. The microcirculation of the hind limbs was also monitored using Laser Doppler fluxmetry. Results: Hematocrit, RBC count, and hemoglobin decreased by the 1st postoperative week. The erythrocyte aggregation values significantly increased in the fistula group by the 5th week (6.43 ± 2.31 vs. 13.60; p < 0.0001; vs. before operation). At the postoperative 1st week in the loop group, the values showed a significant decrease in RBC deformability. During the maturation period, dominantly at the 5th week, all values were normalized. The operated hind limb’s skin microcirculation significantly increased in the sham and loop group by the 1st week (39 ± 10.57 vs. 73.93 ± 1.97 BFU, p < 0.01). This increase wasn’t observed in the fistula group probably due to a steal-effect. Conclusion: Unlike in the loop group, in the presence of the fistula, several rheological parameters have changed. The loop-shaped graft had only minimal impact on micro-rheological parameters.

Abstract
Kidney transplantation is the preferred treatment of end-stage renal disease in children. However, time to transplant varies, making a well-functioning long-term vascular access essential for performing hemodialysis efficiently and without disruption until a kidney becomes available. However, establishing long-term vascular access in pediatric patients can present distinct challenges due to this population's unique characteristics, such as smaller body size and lower-diameter blood vessels. There are three main pediatric long-term vascular access options, which include central venous catheters (CVC), arteriovenous fistula (AVF), and arteriovenous graft (AVG). CVC are currently the most widely used modality, although various studies and guidelines recommend AVF or AVG as the preferred option. Although AVF should be used whenever possible, it is crucial that clinicians consider factors such as patient size, physical exam findings, comorbidities, predicted duration of treatment to decide on the most optimal long-term vascular access modality. This article reviews the three long-term vascular access methods in children and the benefits and complications of each.

Abstract
Native arteriovenous fistula (AVF) is the favorite access for hemodialysis (HD). The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) recommends its creation in most patients with renal failure. Unfortunately, intensive efforts to promote native AVF in patients with marginal vessels have increased the rate of primary fistula failure. A non-functioning fistula prompts the use of central venous catheter (CVC) that, unlike AVF, has been associated with an increased risk of morbidity and mortality among patients receiving HD. We believe that successful and timely AVF placement relies on the development of a multidisciplinary integrated preoperative program divided into five stages: (i) management of patients with advanced chronic kidney disease (CKD), (ii) management of preoperative risk factors for AVF failure, (iii) planning of native AVF, (iv) assessment of patient eligibility and (v) preoperative vascular mapping. Focusing specifically on native AVF, we review scientific evidence regarding preoperative management of this vascular access in order to favor construction of long-term functioning fistula minimizing development of severe complications.

Abstract
Background Dialysis access-associated steal syndrome is a major complication of arteriovenous fistula creation whereby the low-resistance venous conduit shunts arterial inflow through the anastomosis, resulting in clinically significant distal artery insufficiency. Herein, we describe a case of severe steal phenomenon with gangrene of a digit following placement of an arteriovenous fistula that was treated with a novel, entirely endovascular technique. To our knowledge, this was the first totally endovascular approach to dialysis access-associated steal syndrome. Methods Catheterization of the right subclavian, axillary, and brachial arteries was performed. A short 5-Fr sheath was exchanged for a long destination 6-Fr sheath and placed in the proximal brachial artery. An arteriogram showed no stenosis of the arterial system, but did show substantial steal phenomenon with inflow to the arteriovenous fistula, instead of the forearm. We placed a stent graft in the brachial artery across the anastomosis such that the graft covered 3/4 of the length of the opening of the anastomosis. Results Immediately after placement of the stent graft the clinical picture improved dramatically. Patient was followed for 15 months after this procedure until her demise for unrelated causes without ever experiencing dialysis access-associated steal syndrome and with a patent and functional arteriovenous fistula. Conclusion We present a patient with severe dialysis access-associated steal syndrome complicated by third fingertip gangrene, which was successfully treated using a completely endovascular technique. This novel endovascular approach enabled a high-risk patient to avoid open surgery, preserve her limb, and maintain the function of her arteriovenous fistula.
