The aim of this article is to report a case of asymptomatic para-anastomotic aortocaval fistula (ACF) treated by endovascular aortic repair, and to review data of the literature on arteriovenous fistulae (AVF) secondary to abdominal aortic surgery. A 78-year-old male complained of worsening pain in the right lower limb since 2 months. He presented a history of right femoro-popliteal bypass for peripheral arterial occlusive disease and elective surgical treatment for a non-ruptured infrarenal aortic aneurysm (Dacron tube graft)...

Patients with left ventricular assist device have an increased risk for postoperative acute kidney injury and long-term requirement of dialysis. As a chronic access for dialysis, native arteriovenous fistulae are uncommon options due to suspected maturation failure. We present three patients who received successful arteriovenous fistulae placement after left ventricular assist device implantation with assisted long term patency.

We report the case of an 11-year-old girl with heterotaxy syndrome, dextrocardia, and azygos continuation of an interrupted inferior vena cava who had developed pulmonary arteriovenous fistulas after a Kawashima procedure consisting of bilateral superior cavopulmonary anastomoses. She presented with profound cyanosis, fatigue, and failure to thrive. An operative procedure to direct hepatic vein effluent to the pulmonary circulation was performed with placement of an extracardiac conduit between the hepatic veins and the left pulmonary artery...

AIM: To determine whether apoptosis is more common in previously punctured native veins than in non-punctured native veins among patients who undergo surgical creation of arteriovenous fistula (AVF) for dialysis access. METHODS: Cephalic vein specimens were obtained from January 1, 2013 to December 31, 2014 from 60 patients, 30 with previously punctured native veins and 30 with non-punctured native veins. Before AVF placement, a 1-cm vein segment was excised from distal part of the vein for histological, histochemical, and immunohistochemical analysis...

Introduction This study describes results of a modified local thrombolysis technique for acutely thrombosed hemodialysis (HD) arteriovenous fistulas (AVF), which is characterized by prolonged recombinant tissue plasminogen activator (rtPA) local exposure times. Contrary to the standard lyse- and- wait (L&W) technique with local reaction times of 20-40 minutes, the modified protocol allows timing of challenging angioplasty maneuvers to the next regular working day. Methods From February 2009 to April 2014, 84 patients on HD presented with 152 acutely thrombosed AVF...

OBJECTIVE: The autogenous arteriovenous fistula (AVF) has been shown to be superior to the arteriovenous graft (AVG) with respect to cost, complications, and primary patency. Therefore, the National Kidney Foundation Disease Outcomes Quality Initiative guidelines recommend reserving AVGs for patients who do not have adequate superficial venous anatomy to support AVF placement. The brachial artery-brachial vein arteriovenous fistula (BVAVF) has emerged as an autologous last-effort alternative...

BACKGROUND: Chronic kidney disease is common in the United States, with many patients maintained on hemodialysis (HD). The process of HD requires vascular access through an arteriovenous (AV) fistula, AV graft, or central venous catheter. Today, as a result of the National Kidney Foundation's "Fistula First" initiative, nearly 55% of HD patients utilize an AV fistula. As there is significant morbidity and mortality associated with fistula placement and recurrent fistula cannulation, emergency physicians must be equipped to recognize and treat fistula complications...

OBJECTIVE: Delayed maturation of arteriovenous fistulae (AVF) among patients who require hemodialysis (HD) can lead to catheter sepsis with its resultant morbidity and mortality. Some have proposed that sequential balloon-assisted maturation (BAM) may accelerate the maturation times of these accesses. On the other hand, serial balloon angioplasty of normal vein may result in stenosis and delay maturation. Although the safety of BAM has been shown, direct comparison to non-matured AVF has not been explored...

REVIEW
Maria G Marques, Pedro Ponce
Native AV fistulas are considered to be the best VA for most dialysis patients. A careful preoperative process of care is essential to maximize the proportion of fistulas that achieve adequacy for dialysis. An individualized and timely evaluation of patients starts early with the identification of risk factors, followed by a physical examination which should be complemented by ultrasound vascular mapping in most cases. Vascular mapping includes any technique that leads to information on patient's inflow and outflow anatomy (± hemodynamics) as they relate to arteriovenous access creation and may predict maturation...

Ischemic monomelic neuropathy is an uncommon complication associated with the creation of arteriovenous (AV) fistula for hemodialysis. After placement of an arteriovenous fistula, there can be shunting of arterial blood away from the distal extremity resulting in damage to distal nerve fibers with acute neurologic symptoms. It can present with global muscle pain, weakness, and a warm hand with palpable pulses starting within the 1 st h after the creation of the AV fistula. It is a devastating complication and can result in permanent disability...

BACKGROUND AND PURPOSE: Sinus stenosis occasionally occurs in dural arteriovenous fistulas. Sinus stenosis impedes venous outflow and aggravates intracranial hypertension by reversing cortical venous drainage. This study aimed to analyze the likelihood of sinus stenosis and its impact on cerebral hemodynamics of various types of dural arteriovenous fistulas. MATERIALS AND METHODS: Forty-three cases of dural arteriovenous fistula in the transverse-sigmoid sinus were reviewed and divided into 3 groups: Cognard type I, type IIa, and types with cortical venous drainage...

Introduction To increase the rate of arteriovenous fistula (AVF) use, assisted procedures for immature AVF have been strenuously performed. However, this is controversial in that an AVF matured by these assisted procedures may require more frequent intervention to maintain its patency, and have decreased long-term patency. Methods Eighty four AVFs that were matured with assisted maturation procedures and 266 AVFs that matured spontaneously without intervention, created between November 2009 and March 2013 from the hemodialysis (HD) vascular access (VA) cohort, were compared retrospectively and we also investigated the factors that may influence AVF long-term patency...

BACKGROUND AND OBJECTIVES: Dural arteriovenous fistulas are anomalous shunts between dural arterial and venous channels whose nidus is located between the dural leaflets. For those circumstances when invasive treatment is mandatory, endovascular techniques have grown to become the mainstay of practice, choice attributable to their reported safety and effectiveness. We describe the unique and rare case of a dural arteriovenous fistula treated by transarterial embolization and complicated by an intraventricular hemorrhage...

BACKGROUND: Interventional strategies for massive and submassive pulmonary embolism (smPE) have historically included either systematic intravenous thrombolytic alteplase or surgical embolectomy, both of which are associated with significant morbidity and mortality. However, with the advent of endovascular techniques, recent studies have suggested that an endovascular approach to the treatment of acute smPE may be both safe and effective with excellent outcomes. The purpose of this study was to evaluate the outcomes of patients who have undergone catheter-directed thrombolysis (CDT) for smPE at our institution in an effort to determine the safety of the procedure...

Introduction Peripherally inserted central venous catheters (PICCs) may adversely impact future successful arteriovenous fistulae (AVF). As part of a quality improvement project, the performance of tunneled small bore tunneled central venous catheters (TSB-CVCs), as alternatives to PICCs, was evaluated. Methods A retrospective observational study, involving individuals ≥18 years of age who underwent TSB-CVC placement by Interventional Radiology at Mayo Clinic, Rochester, MN between 1/1/2010 and 8/30/2013...

Innominate vein stenosis or thrombotic occlusion can occur in dialysis patients. Central vein stenosis is a common problem in patients on dialysis. Placement of a central vein catheter for dialysis access increases the risk of central vein stenosis. Central vein stenosis sometimes can jeopardize the arteriovenous fistula and arteriovenous graft in the ipsilateral extremity unless recognized early and treated. We describe three patients with left innominate vein stenosis who were known case of chronic kidney disease on haemodialysis and had a left brachio-cephalic fistula and presented with unilateral facial and upper limb oedema...

Patients needing hemodialysis are advised to have arteriovenous fistulas rather than catheters because of significantly lower mortality rates. However, disparities in fistula placement raise the possibility that patient factors have a role in this apparent mortality benefit. We derived a cohort of 115,425 patients on incident hemodialysis ≥67 years old from the US Renal Data System with linked Medicare claims to identify the first predialysis vascular access placed. We compared mortality outcomes in patients initiating hemodialysis with a fistula placed first, a catheter after a fistula placed first failed, or a catheter placed first (n=90,517; reference group)...
