J Vasc Surg 2024; 79:925-930. [PMID: 38237702 DOI: 10.1016/j.jvs.2023.12.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 12/13/2023] [Accepted: 12/14/2023] [Indexed: 02/17/2024]
Abstract
BACKGROUND Patients undergoing arteriovenous (AV) access creation for hemodialysis often have significant comorbidities. Our goal was to quantify the long-term survival and associated risks factors for long-term mortality in these patients to aid in optimization of goals and expectations. METHODS The Vascular Implant Surveillance and Interventional Outcomes Network Vascular Quality Initiative Medicare linked data was used to assess long-term survival in the HD registry. Demographics, comorbidities, and interventions were recorded. Because the majority of hemodialysis patients are provided Medicare, Medicare linkage was used to obtain survival data. Multivariable analysis was used to identify independent associations with mortality. RESULTS There were 13,945 AV access patients analyzed including 10,872 (78%) AV fistulas and 3073 (22%) AV grafts. The median age was 67 years and 56% of patients were male. Approximately one-third had a prior AV access and 44.7% had prior tunneled dialysis catheters. Patients receiving an AV fistula, compared with AV grafts, were more often younger, male, White, obese, independently ambulatory, preoperatively living at home, and less often have a prior AV access and tunneled dialysis catheters (P < .05 for all). The 5-year mortality overall was 62.9% with 61.2% for AV fistulas and 68.8% for AV grafts (P < .001). On multivariable analysis for 5 year mortality, nonambulatory status (hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.53-1.83; P < .001), lower extremity access (HR, 1.67; 95% CI, 1.35-2.05; P < .001), human immunodeficiency virus or acquired immunodeficiency syndrome (HR, 1.44; 95% CI, 1.13-1.82; P < .001), White race (HR, 1.43; 95% CI, 1.35-1.51; P < .001), congestive heart failure (HR, 1.33; 95% CI, 1.26-1.41; P < .001), chronic obstructive pulmonary disease (HR, 1.23; 95% CI, 1.15-1.31; P < .001), and AV graft placement (HR, 1.12; 95% CI, 1.02-1.23, P = .016) were most associated with poor survival. Factors associated with improved survival were never smoking (HR, .73; 95% CI, 0.67-0.79; P < .001), prior/quit smoking (HR, .78; 95% CI, 0.72-0.84; P < .001), preoperative home living (HR, .75; 95% CI, 0.68-0.83; P < .001), and hypertension (HR, .89; 95% CI, 0.8-0.99; P = .03). CONCLUSIONS Long-term survival in Medicare patients undergoing AV access creation is poor with nearly two-thirds of patients having died at 5 years. There are many modifiable risk factors that may improve survival in these patients and give an opportunity for transplantation.

Abstract
BACKGROUND Superior vena cava syndrome in hemodialysis patients resulting from previous or current use of a tunneled central vein catheter is a rare but potentially severe condition. Two aspects have to be addressed during management and treatment: the restoration of central venous flow and the creation of an alternative vascular access to guarantee hemodialysis. RESEARCH DESIGN Conforming to the current guidelines and literature, we present a stepwise approach and discuss therapeutic options. The removal of the tunneled central vein catheter should be attempted and a native vascular access created whenever feasible. RESULTS First, an upper extremity AVF should be preserved or, as in our case, made functional. Endovascular treatment of CVSO should primarily consist of balloon dilatation. Placement of a stent or stent graft should be considered as a secondary option. HeRO graft placement may be considered in recurrent CVSO and recanalization with a Surfacer. LL-AVF or AVG need to be discussed and may be an alternative for certain HD patients when the risk of lower limb ischemia and infection is considered. CONCLUSION Several therapeutic options are available and the basic principles are well established in the literature, although the level of evidence is not high. Therefore, we propose a stepwise and interdisciplinary approach to guide the challenging decision-making process in SVC.

Abstract
INTRODUCTION Hemodialysis forms the most common replacement therapy for majority of Indians suffering from chronic kidney disease (CKD). Multiple access failure and central vein stenosis has become commonplace in Indian dialysis access patients and there is a burgeoning need for more advanced hemodialysis (HD) access options. Upper thigh arterio-venous grafts (AVG) are seldom inserted due to fear of infection and limb ischemia. MATERIALS AND METHODS This is a single institutional, retrospective, descriptive case study of consecutive patients who underwent upper thigh prosthetic AVG over a period of 7 years. All these patients had exhausted options of upper limb access and or had central vein stenosis. AVG from the proximal superficial femoral artery (SFA) to the proximal great saphenous vein (GSV) in a loop configuration using polytetrafluoroethylene (PTFE) was carried out in the upper thigh. RESULTS A total of 24 patients had undergone upper thigh loop AVG. Their age varied from 24 to 77 years. The median follow-up period was 3 years. Five of these grafts developed infection (21%) which led to primary failure. A primary patency of 71% (17/24 patients) was achieved at 1 year. Thrombosis developed at a mean of 16.7 months after the primary procedure. Adjunctive procedures such as thrombectomy, segmental replacement of graft, patch angioplasty, balloon angioplasty, and stenting were required in 75% of patients to achieve a secondary patency of 86% at 1 year. Three grafts were explanted without limb loss. CONCLUSION Upper thigh loop AVG forms a reliable alternate dialysis access option for patients with failed upper limb access sites or central vein occlusion. Adjunctive procedures are key to maintaining patency in these grafts. Good secondary patency is achievable, and the infection rates are similar to arm AVG. Close follow-up and timely intervention are key to long term dialysis through these grafts.

Revision of Aneurysmal Arteriovenous Access with Immediate Use Graft Is Safe and Avoids Prolonged Use of Tunneled Hemodialysis Catheters. Ann Vasc Surg 2022; 87:295-301. [PMID: 36162627 DOI: 10.1016/j.avsg.2022.09.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Revised: 07/24/2022] [Accepted: 09/11/2022] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Aneurysmal AVF can pose a difficult treatment dilemma for the vascular surgeon. Prolonged tunneled dialysis catheters (TDC) in patients requiring long-term dialysis are associated with significantly increased mortality compared to arteriovenous fistulas (AVF). We aimed to elucidate the outcomes of aneurysmal AV access revision with aneurysm resection and Artegraft® (LeMaitre, New Brunswick, NJ) Collage Vascular Graft placement to avoid prolonged use of TDCs. METHODS We reviewed all patients with aneurysmal AV access in which the access was revised with aneurysm resection and jump graft placement at a single institution from 2018 to 2021. Outcomes were time to cannulation, reintervention rates, time to reintervention and patency (primary, primary assisted and secondary). Patency rates were estimated with Kaplan-Meier Survival analysis. RESULTS A total of 51 revised aneurysmal AV access in 51 patients were studied, of which 23.5% (n=12) had perioperative TDC placement. Three patients were done for emergent bleeding. The cohort was 62.8% male (n=32) with a median age of 58 years (IQR: 49-67). Most patients had brachiocephalic AVF (n=37 [72.6%]). Median follow up time was 280 days. Median time to cannulation was 2 days. Time to cannulation was significantly longer in patients with perioperative TDC as compared with those without TDC (24 days vs 2 days, P<0.001). Reintervention was required in 41.2% of patients (n=21), at median time of 47 days. At 30, 90, 180, and 365 days, primary patency rates were 84.3%, 78.3%, 66.6%, and 54.9%; primary assisted patency rates were 94.1%, 88.1%, 79.4%, and 79.4% and secondary patency rates were 100%, 97.8%, 91.6% and 91.6% respectively. CONCLUSIONS Revision of aneurysmal AV access (urgent or elective) with Artegraft as jump graft is safe, with acceptable short and mid-term patency results. This allows dialysis patients to continue to have a functional access, decreasing the need for a tunneled catheter and reducing the associated risk of sepsis and increased mortality. This should be considered for all patients with aneurysmal, dysfunctional fistulas to maintain AV access and avoid TDC placement.

Long-term outcomes of transposed femoral vein arteriovenous fistula for abandoned upper extremity dialysis access. J Vasc Surg 2021; 74:225-229. [PMID: 33348002 DOI: 10.1016/j.jvs.2020.12.065] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Accepted: 12/05/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND The number and longevity of patients with end-stage renal disease requiring dialysis access have continued to increase, leading to challenging situations, including exhausted upper extremity access and severe central venous stenosis. This has led to an increase in the use of alternative access sites, including the lower extremities. The transposed femoral vein arteriovenous fistula for dialysis access is a previously described alternative, although limited data are available on its long-term patency. METHODS Patients treated with a transposed femoral vein fistula were retrospectively reviewed. A transposed femoral vein fistula was created by harvesting the femoral vein and transposing it to the distal superficial femoral artery at the level of the adductor canal. The demographic information, perioperative characteristics, complications, and long-term outcomes were recorded and analyzed. RESULTS A total of 21 patients had undergone transposed femoral vein fistula for dialysis access after an average of 5.3 ± 2.8 failed dialysis access procedures and a duration of 6.1 ± 4.9 years from the initiation of dialysis. The average age at the procedure was 53.5 ± 12.8 years. Ten patients (47.6%) had a history of diabetes mellitus and nine (42.9%) had a history of coronary artery disease. Technical success was achieved in 100% of cases, and 16 patients (76.2%) were discharged with anticoagulation therapy. The primary patency at 1, 3, and 5 years was 93%, 74%, and 74%, respectively. The secondary patency at 1, 3, and 5 years was 100%, 89%, and 89%, respectively. Two patients had compartment syndrome requiring fasciotomy, and six patients experienced wound complications. CONCLUSIONS Transposed femoral vein fistula for dialysis access is a viable alternative for patients with an exhausted upper extremity access, with good long-term patency.

Abstract
OBJECTIVE Tunneled dialysis catheters (TDCs) are generally used as a temporary means to provide hemodialysis until permanent arteriovenous (AV) access is established. However, some patients may have long-term catheter-based hemodialysis because of the lack of alternatives for other dialysis access. Our objective was to evaluate characteristics of patients with, reasons for, and mortality associated with long-term TDC use. METHODS A retrospective single-institution analysis was performed. Long-term TDC use was defined as >180 days without more than a 7-day temporary removal time. Reasons for long-term TDC use and complications were recorded. Summary statistics were performed. Kaplan-Meier analysis compared mortality between patients with long-term TDC use and a comparison cohort who underwent AV access creation with subsequent TDC removal. RESULTS We identified 50 patients with long-term TDC use from 2013 to 2018. The average age was 63 years, 44% were male, and 76% were African American. Previous TDC use was found in 42% of patients with subsequent removal after alternative access was established. Median TDC duration was 333 days (range, 185-2029 days). The primary reasons for long-term TDC use were failed (occluded) AV access (34%), nonmaturing AV (nonoccluded) access (32%), delayed AV access placement (14%), no AV access options (10%), patient refusal for AV access placement (6%), and medically high risk for AV access placement (4%). In 46% of patients, TDC complications including central venous stenosis (33.4%), TDC-related infections (29.6%), TDC displacement (27.8%), and thrombosis (7.9%) occurred. Overall, 47.6% required a catheter exchange during the prolonged TDC period. The majority (76.4%) had the catheter removed because of established alternative access during follow-up. The long-term TDC group, in relation to the comparator group (n = 201), had fewer male patients (44% vs 61.2%; P = .028) and higher proportion of congestive heart failure (66% vs 40.3%; P = .001). Kaplan-Meier analysis showed no significant difference in survival at 24 months for the long-term TDC group compared with the comparator group (93.6% vs 92.7%; P = .28). CONCLUSIONS Patients with long-term TDCs experienced significant TDC-related morbidity. Whereas permanent access is preferable, some patients may require long-term TDC use because of difficulty in establishing a permanent access, limited access options, and patient preference. There was no difference in survival between the groups.
