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 (IV TPA) 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...

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)...

BACKGROUND AND OBJECTIVES: Few studies have evaluated vascular access use after transition from peritoneal dialysis to hemodialysis. Our study characterizes vascular access use after switch to hemodialysis and its effect on patient mortality and evaluates whether a peritonitis event preceding the switch was associated with the timing of permanent vascular access placement and use. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The US Renal Data System data were used to evaluate the establishment of a permanent vascular access in 1165 incident Medicare-insured adult patients on dialysis who initiated peritoneal dialysis between July 1, 2010 and June 30, 2011 and switched to hemodialysis within 1 year...

Acquired hemophilia A (AHA) is a rare bleeding disorder caused by autoantibodies to coagulation factor VIII (FVIII). AHA onset during the induction of dialysis is extremely rare, and the management of blood access is difficult. We present a case of AHA that developed during induction of dialysis and treatment with double filtration plasmapheresis (DFPP). An 86-year-old man with chronic kidney disease was admitted to our hospital with multiple subcutaneous hemorrhages. Because of his prolonged activated partial thromboplastin time (aPTT) and high titer of inhibitors to FVIII, he was diagnosed with AHA, and prednisolone treatment was started...

Arteriovenous fistulae (AVF) are the favoured choice of vascular access but still have poor long term success. Haemodynamic parameters play an important role in vascular health and have been linked to the development of intimal hyperplasia (IH), a pathological growth of the blood vessel initiated by injury. This study aimed to investigate the haemodynamics surrounding the arterial needle (AN) and venous needle (VN), using computational fluid dynamics. A range of blood flow rates, needle positions and needle orientations were examined...

Microvascular free tissue transfer is a routine procedure with high predictability and a low complication rate. However, compromised flap perfusion remains a challenge and there is no consensus regarding the appropriate flap salvage protocol. The purpose of this study was to identify techniques with implications for flap salvage procedures and to assess their efficacy. A systematic review of studies published in the literature between 1990 and 2015, with predefined inclusion and exclusion criteria, was performed...

The spleen and pancreas are at risk for injury during abdominal trauma. The spleen is more commonly injured because of its fragile structure and its position immediately beneath the ribs. Injury to the more deeply placed pancreas is classically characterized by discordance between the severity of pancreatic injury and its initial clinical expression. For the patient who presents with hemorrhagic shock and ultrasound evidence of major hemoperitoneum, urgent "damage control" laparotomy is essential; if splenic injury is the cause, prompt "hemostatic" splenectomy should be performed...

Karen Woo, Charmaine E Lok
Optimal vascular access planning begins when the patient is in the predialysis stages of CKD. The choice of optimal vascular access for an individual patient and determining timing of access creation are dependent on a multitude of factors that can vary widely with each patient, including demographics, comorbidities, anatomy, and personal preferences. It is important to consider every patient's ESRD life plan (hence, their overall dialysis access life plan for every vascular access creation or placement). Optimal access type and timing of access creation are also influenced by factors external to the patient, such as surgeon experience and processes of care...
