Changes in Cardiac Structure and Function Following Fistula Ligation in Kidney Transplant Recipients (Cohort Study)

Purpose: International guidelines recommend that haemodialysis access is provided by an arteriovenous fistula (AVF), which enables frequent, reliable access to the circulation, but there are no guidelines to suggest whether these AVFs need to be ligated after kidney transplantation. Cardiovascular morbidity and mortality remain high in recipients of a kidney transplant, the persistence of a patent arteriovenous fistula (AVF) after transplantation may contribute to ongoing maladaptive cardiovascular remodelling. The ability to reverse this maladaptive remodelling by ligation of this AVF is unknown. We conducted this trial to evaluate the effect of AVF ligation on cardiac structure and function in stable kidney transplant recipients. Also we studied the ability of preoperative echocardiographic and non-invasive hemodynamic measurements, including the effects of acute temporary occlusion of the fistula, to predict postoperative left ventricular diameter and mass reduction, by the closure of the fistula.
 Materials and Methods: Nonrandomized controlled trial. kidney transplant recipients (>12 months after transplantation with stable graft function) were divided into 2 groups. The first referred for surgical arteriovenous fistula closure. The second group didn’t receive Fistula closure (control). Standard echocardiographic parameters, heart rate, and blood pressure were assessed preoperatively (fistula closure) at baseline. These measurements were repeated 6 months after surgical closure.
 Findings: Seventeen kidney transplant patients were prospectively studied with 11 case and 6 controls with no fistula closure. Surgical fistula closure decreased left ventricular end-diastolic diameter and mass indexes (29.9_2.4to 27.4_2.1 mm/m2, P<0.001, and 141_37 to 132_39 g/m2, P<0.05, respectively), whereas no changes were seen in controls after a similar delay. Postoperative left ventricular end-diastolic diameter and mass reductions correlated best with the increases in total peripheral resistance (r_0.85, P<0.0001) and mean arterial blood pressure (r_0.64, P_0.006), respectively.
 Conclusions. Surgical closure of arteriovenous fistula reduces left ventricular diameter and mass in kidney transplant recipients. The best predictors of those morphological changes are the rise in blood pressure and total peripheral resistance induced by temporary occlusion of the fistula.
 Implications to Theory, Practice and Policy: Surgical closure of persistent AV fistula after renal transplantation to correct LV geometry and improve symptoms in terms of exertional dyspnea and palpitations.

Abstract 15479: High Output Cardiac Failure Associated With Arteriovenous Fistula

Introduction: High output heart failure (HOHF) secondary to arteriovenous fistula (AVF) is known. However, having a high index of suspicion for the latter when encountering diuretic resistance in patients with a remote history of hemodialysis is key. Case A 68-year-old female with a history of kidney transplant in 2012 with no recent dialysis, hypertension, hyperlipidemia, pulmonary hypertension, heart failure with reduced ejection fraction, and atrial fibrillation presented with decompensated heart failure and acute kidney injury (AKI). Physical exam was remarkable for anasarca, and no apparent fistulas were noted. She was started on milrinone and furosemide drips. Clinical decision making Initial transthoracic echocardiogram (TTE) revealed an ejection fraction (EF) of 20%, which declined from 35%, along with new mitral and tricuspid regurgitation. Her hospitalization was complicated by altered mental status, worsening AKI requiring hemodialysis, atrial fibrillation with rapid ventricular response, and resistance to multiple diuretics and after-load reduction combinations. Diuretics and inotropic support were discontinued due to worsening clinical status. Given concerns for valvular disease, a transesophageal echocardiogram was obtained, confirming moderate to severe mitral and tricuspid valve regurgitation, bi-atrial enlargement, and reduced biventricular function. However, the patient was not clinically optimized for Mitra-clip. Further hemodynamics and volume status assessment with RHC revealed a mean PAP 44, PCWP 26, and CO 11 L/min. RHC results raised suspicion for HOHF. Interestingly, the patient was noted to have a right inguinal surgical scar with a palpable thrill, and an arteriovenous graft duplex revealed high volume flow. The patient underwent ligation of the right inguinal fistula. Repeat TTE two weeks post AVF ligation showed EF of 40% and improved functional mitral and tricuspid valve regurgitation. The patient ultimately was taken off hemodialysis and had clinically improved heart failure. GDMT was optimized, and outpatient evaluation for mitral valve intervention was scheduled. Conclusion Longstanding AVF can cause HOHF. Early index of suspicion is warranted for AVF ligation as it results in rapid EF recovery.

Painless ulceration due to digital hypoperfusion ischaemic syndrome: case report and literature review

Digital hypoperfusion ischaemic syndrome (DHIS), also known as steal syndrome, is a well recognised serious complication of haemodialysis (HD) access creation. The clinical presentation varies from cyanosis to tissue loss due to necrosis or gangrene. In this article, we present a case of painless digital ulceration due to DHIS and provide a review of the literature. A 40-year-old-female presented with multiple painless digital ulcerations of the left hand. Her medical profile included atherosclerotic disease, hypertension, hyperparathyroidism and type I diabetes causing retinopathy, peripheral neuropathy, gastroparesis and end-stage renal disease (ESRD). Her ESRD required HD with the construction of a left-arm basilic vein transposition arteriovenous fistula (AVF). A year later, she developed intermittent, painless ulcerations of the left hand. A Doppler ultrasound confirmed the diagnosis of DHIS. The patient was treated with AVF ligation surgery. At six months postoperatively, she had near complete re-epithelialisation of her ulcers. This case is unique in that the patient did not have preceding pain, likely due to her underlying diabetic neuropathy. While DHIS in haemodialysis patients with AVF is well documented in literature, digital ulceration in this context is an advanced form of this condition. Early recognition of digital ulceration as a complication of DHIS may enable early intervention and prevent permanent damage.

The Effect of Elective Ligation of the Arteriovenous Fistula on Cardiac and Renal Functions in Kidney Transplant Recipients.

Kidney transplantation (KTx) is considered as the best kidney replacement therapy and arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. The systematic ligation of a functioning AVF in stable kidney transplant recipients remains debatable. In this prospective study, we investigated the hemodynamic impact of the surgical closure of AVF in KTRs. Forty-three KTRs underwent an ambulatory blood pressure monitoring (24h-ABPM) before surgical closure of AVF (T0) and 12 months later (M12), as well as measurement of serum cardiac biomarkers (i.e., soluble suppression of tumorigenicity 2 (ST2), N-terminal pro b-type natriuretic peptide (NT-proBNP) and Galectin-3). Serum tests were also performed 6 months after AVF closure (M6). An echocardiographic exam was done at each time-point. All serum creatinine values were collected to compare the individual eGFR slopes before versus after AVF closure. The latest measure of the AVF flow (QAVF) prior to KTx was recorded. Diastolic blood pressure (DBP) significantly raised from T0 to M12: + 4.4±7.3 mmHg (p=0.0003) for 24h, + 3.8±7.4 mmHg (p=0.0018) during the day, and + 6.3±9.9 mmHg (p=0.0002) during the night, leading to an increased proportion of KTRs with ESH-defined arterial hypertension after AVF ligation. No change was observed for systolic BP. NT-proBNP significantly dropped between T0 and M6 (345 [190; 553] to 230 [118; 458] pg/mL, p=0.0001) and then remained stable from M6 to M12, while ST2 and Galectin-3 levels did not change from T0 to M12. We observed a significant decrease of left ventricular (LV) end-diastolic volume, LV end-systolic volume, LV mass, interventricular septum diameter, left atrial (LA) volume, and tricuspid annular plane systolic excursion from T0 to M6, and then a stability from M6 to M12. LV ejection fraction and eGFR slope remained stable during the whole study. These observations remained unchanged after adjustment for QAVF. The closure of a patent AVF in KTRs is associated with elevation of DBP, drop of serum NT-proBNP levels, reduction of LV/LA dimensions, and stable eGFR slope.

Inferior Epigastric Artery Pseudoaneurysm Following Laparoscopic Appendectomy.

An inferior epigastric artery pseudoaneurysm is an exceptionally rare occurrence. Formation of an inferior epigastric artery pseudoaneurysm can be seen following surgical intervention and is more common after laparoscopy. A sixty-eight-year-old male presented with a right upper quadrant bulge at his incision site two months following laparoscopic appendectomy. The patient reported sudden onset of a non-reducible bulge at a 5mm trocar incision site with minimal pain and without obstructive symptoms. Computed tomography of his abdomen and pelvis with intravenous contrast revealed a 4.2cm pseudoaneurysm with peripheral thrombosis within the right inferior epigastric artery. The patient subsequently underwent open exploration with the evacuation of pseudoaneurysm thrombus and ligation of arteriovenous fistula. The patient recovered well without complication from pseudoaneurysm. Inferior epigastric artery pseudoaneurysm following any laparoscopic procedure is rare. This case highlights the importance of understanding the abdominal wall anatomy and its vascular supply to avoid such injury. We present this case to bring light to this rare occurrence and to highlight the importance of proper trocar placement during any laparoscopic procedure.

Long-Term Safety, Efficacy, Indications, and Criteria of Arteriovenous Fistula Ligation Following Kidney Transplant: A Patient-Driven Approach.

In patients with end-stage renal disease, arteriovenous fistulas are the standard of care to ensure long-term vascular access. Recent studies suggest some long-term posttransplant cardiac benefits and quality of life improvements in kidney transplant recipients due to arteriovenous fistula ligation. However, there are no guidelines regarding arteriovenous fistula management after transplant. Our study objective was to evaluate the long-term safety of arteriovenous fistula ligation and the frequency of returning to hemodialysis after ligation. Retrospective chart review from February 2014 to December 2020 identified 578 adult patients who underwent successful kidney transplant at our center. Of these patients, 47 underwent subsequent arteriovenous fistula ligation. Both medically driven and patient-driven cases were assessed and approved by a transplant nephrology team with regard to allograft function and ligation suitability. Our results showed that, of the 47 renal transplant patients, 70.2% chose to undergo arteriovenous fistula ligation due to aneurysmal formation, 44.7% due to pain, and 14.9% due to high-output heart failure. In total, 68.1% of arteriovenous fistula ligations performed were primarily patient driven. There was an average follow-up of 2.9 years after ligation, with 1 unrelated reoperation and no returns to dialysis for all patients who underwent arteriovenous fistula ligation. In our study, the long-term risks of surgical complications and allograft impairment after ligation were negligible. As a result of our current findings and known positive cardiovascular benefit, patient-driven arteriovenous fistula ligation after kidney transplant should be routinely considered in patients with stable allograft function.

Optimizing Arteriovenous Fistula Care in Kidney Transplant Recipients: A Complex Task.

An unusual cause of venous hypertension

The gold standard vascular access for hemodialysis is the arteriovenous fistula (AVF). Venous hypertension (VH) is an unusual complication of AVF, which can be misdiagnosed as cellulitis due to the similarities in clinical presentation. Here we present a case of venous hypertension in a 40-years-old gentleman, who presented with progressive pain and swelling of three lateral fingers of his left hand without other inflammatory signs after a year of AVF creation. Further evaluation with a duplex scan supported the clinical diagnosis of VH. He had undergone a surgical ligation of AVF and completely recovered from the symptoms.

Traumatic Superficial Femoral Arteriovenous Fistula with Pulsatile Mass and Leg Pain 60 Years after Stabbing Injury.

Post-traumatic arteriovenous fistula (AVF) is a vascular injury complication and can present with vessel dilation, forming pulsatile varices, venous hypertension, distal ischemia, and congestive heart failure. We present a case of only pulsatile mass and leg pain caused by a 60-year-old post-traumatic AVF. Computed tomography angiography showed an AVF between the superficial femoral artery and superficial femoral vein. Surgical repair with AVF ligation was successfully performed. Traumatic AVF caused vascular and heart failure in the future; therefore, post-traumatic AVF is better eliminated as soon as possible.

True Brachial Artery Aneurysm in Patients with Previous Arterio-Venous Fistula Ligation and Immunosuppressant Therapy for Renal Transplantation: Case Report and Literature Review.

Background/Objective: Brachial artery aneurysm (BAA) is a serious complication in patients with previous arterio-venous fistula (AVF), renal transplantation (RT), and immunosuppressive regimens. Until now, there has been no standard of care for these patients, especially for patients undergoing chronic dialysis and immunosuppressive treatment. The aim of this study was to investigate data from the literature regarding these patients and to suggest recommendations for the best approach to their treatment. Methods: A review of the literature was performed by searching the PubMed database in the English language. The review was accompanied by two case reports. A total of 24 articles with different variables—demographics, renal transplantation, aneurysm size, and type of surgery—were subjected to the review. In addition, two cases are reported. Conclusion: This review suggests that the best treatment for these patients is open surgery, with aneurysmectomy and graft interposition. Results: All patients had RT. The age of patients ranged from 26–77 yo, with a male predominance. The majority had an AVF ligated after RT. The main clinical symptoms were pain, swelling, and pulsatile mass (66%). All patients, except one, were treated through open surgery. The first option for treatment was reversed saphenous vein graft interposition (36%), followed by ePTFE graft (16%).

Pathophysiology of High Output Arteriovenous Fistula with Heart Failure: A Systematic Review and Meta-analysis

Introduction: Arteriovenous Fistula (AVF) is extensively used as vascular access for haemodialysis patients. It induces a high output state, which is associated with cardiac remodeling. With High Output Heart Failure (HOHF), the AVF occupies a low pressure; reduced vascular resistance and increased venous return. The High Output Arteriovenous Fistula with Heart Failure (HOHF-AVF) patients often undergo a comprehensive assessment of type of underlying diseases, the degree of vasodilatation along with laboratory investigations and cardiac imaging. Hence identification of the pathophysiological determinants of HOHF-AVF is intriguing. Aim: To identify the pathophysiological determinants of HOHF-AVF. Materials and Methods: This systematic review was conducted from May 2021 to December 2021 at the Department of Cardiovascular Surgery, Imperial College, United Kingdom. Randomised Controlled Trials (RCTs), cohort, case-control, cross-sectional and descriptive studies, conducted on adult patients who underwent AVF creation or ligation and addressed the pathophysiological determinants of HOHFAVF were included. Studies conducted among Paediatric cases, case reports, and case series were excluded. Medline (PubMed), EMBASE, ProQuest, and the Cochrane database were searched, by utilising the key words {[(“HOHF” OR “High output heart failure”) AND (“AVF” OR “Arteriovenous fistula”)] AND (“LV parameters” OR “Structural Characteristics” OR “Echocardiographic indices)}. The searches were restricted from January 2000 to October 2021 with studies published in the English language. All the included studies were subjected to critical appraisal using the “Cochrane risk of bias assessment tool” for RCTs, and the “Joanna Briggs Institute (JBI) checklist” for cohort, case-control, cross-sectional and descriptive studies. For meta-analysis Mantel-Haenszel Odds Ratio (M.H. O.R.) with its 95% Confidence Interval (C.I), Mean Difference (M.D) with its 95 % C.I were computed. The Review Manager Software (Rev Man 5, Cochrane collabouration, Oxford, England) was used for data analytics. Results: Overall, 115 citations were identified from the initial search, of which 29 studies were retrieved. Later, 14 studies were excluded. Of the remaining 15 studies, 12 were subjected to meta-analysis. There was a change in Left Ventricular (LV) end diastolic diameter (M.D=2.0; p<0.001; 95% C.I=1.13 to 2.86), and cardiac index (M.D=0.63; p<0.001, 95% C.I=0.46 to 0.79) from baseline to atleast three months of postsurgery among HOHF-AVF patients. According to the AVF flow, there was a change in LV systolic diameter (M.D=-18.90; p<0.01; 95% C.I=-22.84 to-14.96), cardiac index (M.D=0.50; p=0.007; 95% C.I=0.14 to 0.86) and tricuspid annular plane systolic excursion (M.D=3.90; p=0.03; 95% C.I=0.30 to 7.50). Conclusion: Left ventricular end diastolic diameter and cardiac index were found to be the major determinants for a HOHFAVF. The left ventricular mass index, ejection fraction, posterior wall thickness, interventricular septum were not associated with HOHF-AVF. Left ventricular systolic diameter, cardiac index and tricuspid annular plane systolic excursion were the determinants of AVF flow.

Alternant Approach to Manage Patent AVF With Untreatable Venous Hypertension from Central Stenosis

<h3>Introduction and Objective</h3> Arteriovenous fistula (AVF) associated venous hypertension from central venous obstruction is commonly seen to cause dysfunctional dialysis access and severe swelling. It is traditionally managed by a variety of surgical, interventional approaches, but when the central stenosis/occlusion cannot be corrected, focus shifts only to relieve the edema. The most common approach is sacrificing the vein with ligation and starting anew despite risks of non-maturity and/or using a non-autologous conduit. We report a novel approach by translocating a patient's native and "mature" vein to create a new AVF and treat both problems. This minimizes time-to-maturity, quickly establish long-term, autologous vascular access for hemodialysis and simultaneously treat the swollen extremity. <h3>Case Report</h3> 80-year-old female with a functional brachiocephalic AVF had severe and painful venous hypertension due to presumed central vein obstruction. The AVF was created in 2017 and unused until November 2019. It worked for 7 months until developing left upper extremity swelling and pain. She underwent five balloon angioplasty procedures at an outside facility without lasting resolution. In January 2021 her left upper extremity was tense, edematous and significant erythema. The left arm had evolving elephantiasis with Peux D'Orange skin changes, warmth, tenderness, with a distant, but palpable thrill. We attempted resolution via femoral venous access which revealed a >70% stenosis of her subclavian vein close to the innominate junction and near her first rib and clavicle interface. Balloon angioplasty with a 12 × 40mm Conquest balloon at 20 ATM had immediate reversal of her venous hypertension and symptomatic relief. At one month she reported recurrence of swelling and pain. We discussed first rib resection, AVF ligation and/or catheter-only dialysis or starting again. She refused a rib resection. We harvested and excised her large and mature left cephalic vein and translocated it to her right forearm to create a new radial artery to Brachial vein AVF (with a tunneled catheter for acute access). Due to size mismatch, we everted the left cephalic vein to do valvulotomy, and the anastomosis was done in a non-reversed fashion with two end-to-side anastomosis. This simultaneously corrected her venous hypertension and gave her an autologous AVF using her contralateral cephalic vein. At one month, her left upper extremity had complete resolution and the AVF was cleared for access. <h3>Discussion</h3> Venous hypertension and central venous obstruction with a functional AVF can compromise efficient dialysis and be very debilitating leading to AVF ligation and abandonment when it cannot be resolved. This approach offers an accessible technique for salvage of a relatively common AVF complication with high success for cannulation.

Long-Term Impact of Arteriovenous Fistula Ligation on Cardiac Structure and Function in Kidney Transplant Recipients: A 5-Year Follow-Up Observational Cohort Study.

The long-term effects of arteriovenous fistula (AVF) ligation on cardiovascular structure following kidney transplantation remain uncertain. A prospective randomized, controlled trial (RCT) examined the effect of AVF ligation at 6 months on cardiovascular magnetic resonance imaging (CMR)-derived parameters in 27 kidney transplant recipients compared with 27 controls. A mean decrease in left ventricular mass (LVM) of 22.1 g (95% CI, 15.0 to 29.1) was observed compared with an increase of 1.2 g (95% CI, -4.8 to 7.2) in the control group (P<0.001). We conducted a long-term follow-up observational cohort study in the treated cohort to determine the evolution of CMR-derived parameters compared with those documented at 6 months post-AVF ligation. We performed CMR at long-term follow-up in the AVF ligation observational cohort from our original RCT published in 2019. Results were compared with CMR at 6 months postintervention. The coprimary end point was the change in CMR-derived LVM and LVM index at long-term follow-up from imaging at 6 months postindex procedure. At a median of 5.1 years (interquartile range, 4.7-5.5 years), 17 patients in the AVF ligation group were studied with repeat CMR with a median duration to follow-up imaging of 5.1 years (IQR, 4.7-5.5 years). Statistically significant further reductions in LVM (-17.6±23.0 g, P=0.006) and LVM index (-10.0±13.0 g/m2, P=0.006) were documented. The benefit of AVF ligation on LVM and LVM index regression appears to persist long term. This has the potential to lead to a significant reduction in cardiovascular mortality.

Arteriovenous Fistula Rescues Radial Forearm Phalloplasty: A Case Report on Patients with Microvascular Obstruction

Background:Radial forearm free flap phalloplasty (RFFFP) is the most common surgery performed for genital reconstruction of female-to-male transgender patients. However, up to 19% require anastomotic re-exploration. The postoperative creation of an arteriovenous fistula (AVF) to bypass obstruction and salvage RFFFP was first reported in 1996 and has subsequently been reported by 1 high-volume center in Belgium.Methods:Here, we present 2 cases in which intraoperative microvascular obstruction threatened the viability of the RFFF of transgender phalloplasty patients. In each patient, an AVF was created between the radial artery and cephalic vein in the distal flap either after being transferred out of the operating room, as has previously been described, or during initial operation.Results:In both cases, the creation of a distal AVF salvaged the neophallus. Importantly, the patient that had been transferred out of the operating room before reintervention suffered partial flap necrosis compared with no flap loss in the patient who had an AVF created during initial surgery. One AVF was ligated 18 days postoperative, whereas the other was never formally closed.Conclusions:These cases demonstrate that AVF can be reliably used for RFFFP salvage both intraoperatively and for reintervention. They also suggest that earlier detection of persistent vascular compromise and utilization of AVF can further minimize flap loss. Finally, in contrast with the prior explanation of this technique, timing of AVF ligation may be less critical than previously described. Microsurgeons are reminded that this technique may save complicated flaps in the uncommon case of microcirculatory flap obstruction.

POS-562 ISCHEMIC DISTAL HAND STEAL SYNDROME : A RARE COMPLICATION OF AVF

Ischemic steal syndrome is a rare complication of arteriovenous fistula creation due to high blood flow in a low resistance vein and reversal of flow away from the higher resistance distal arterial bed into the vein. Several options including ligation of arteriovenous fistula, banding, proximalization of arterial inflow and distal revascularization and interval ligation (DRIL).

To ligate or not to ligate hemodialysis arteriovenous fistulas in kidney transplant patients.

There is significant disagreement about maintenance or ligation of arteriovenous fistulas (AVFs) in kidney transplant patients (KTPs). Potential harms from maintaining AVFs are their impact on cardiac function, cosmetic concerns and complications such as bleeding and rupture. High flow AVFs can place a strain on the heart and cause or exacerbate pre-existing cardiac dysfunction. There is an improvement in cardiac function after kidney transplantation independent of vascular access status. Studies comparing cardiac parameters in patients with and without AVFs after renal transplantation have shown conflicting results. Ligation of high flow AVFs in KTPs resulted in improvement in cardiac function and prevention of heart failure. In KTPs with deteriorating renal function and high flow AVFs, banding of the AVFs to reduce flow is an option. Patients who retain AVFs after renal transplant have the advantage of immediate, optimal access should the transplant fail and may have preserved kidney function. The patient's post-transplant kidney function, risk factors for transplant loss, AVF blood flow, and cardiac function play an important role when making the decision to ligate or preserve AVFs.

High-output cardiac failure secondary to arteriovenous fistula: a wide-based literature review

Performing arteriovenous fistula (AVF) has become common among patients requiring hemodialysis. Apart from complications like bleeding, stenosis, infection, and thrombosis, even high-output cardiac failure has been a matter of concern for these patients. Sever risk factors like upper arm AVF with brachial artery anastomosis, male sex, and volume expansion has been identified. The pathophysiology contributing to this disease process is the shunting of blood from the high-resistance arterial system into the lower resistance venous system, increasing the venous return and eventually cardiac failure. It is also believed cardiac failure in AVF is also a reflection of the underlying cardiovascular disease. This is diagnosed using an echocardiogram and cardiac biomarkers (brain natriuretic peptide & atrial natriuretic peptide). AVF ligation has been shown to improve symptoms of cardiac failure at the expense of losing vascular access. Current guidance recommends schematic predialysis planning process with the aim of optimizing the route of dialysis for an individual patient’s unique psychological, medical and wider social implications.

The attitude of kidney transplant recipients towards elective arteriovenous fistula ligation.

Arteriovenous fistulas (AVF) are a source of various complications. Among previously hemodialyzed kidney transplant recipients (KTxR), the AVF may persist over time. The patients' decisions whether to ligate the functioning AVF may be prompted by many factors. Our knowledge of benefits concerning the procedure as well as patients' attitude towards it is scarce. Evaluation of the patients' opinion on the persistent AVF ligation after a successful kidney transplantation. An anonymous survey was carried out among 301 previously hemodialyzed KTxR. The patients were recruited during scheduled visits in the Transplantation Outpatient Unit. All subjects completed an anonymous questionnaire including questions about their attitude towards the matter in question. 69 patients (22.9%) have considered AVF closure. The most common causes for such attitude were esthetic reasons (n = 29) and concerns about heart health (n = 13). Among those 69 subjects, 18 have presented with symptomatic AVF due to multiple symptoms. Symptomatic AVFs were localized on the forearm in 14 out of 18 cases. As many as 116 (38.5%) cases have never wanted to ligate the AVF and 116 (38.5%) subjects did not have a clear opinion. In our study we report 158 (52.5%) cases of non-functioning AVFs. The main reason for the above was spontaneous AVF thrombosis (121 cases). Only 24 subjects reported to rely on the physician-provided information about the AVF management. One fourth of KTRs have ever considered AVF ligation. There is a distinct need for educating patients on the possibilities of post-transplantation AVF management.
