PURPOSE: Previous reports have suggested higher periprocedural complications after ipsilateral antegrade femoral arterial access (AA). We looked at a contemporary series comparing complication rates between AA and contralateral retrograde femoral arterial access (RA) for femoropopliteal angioplasty. METHOD: A prospective review of all cases between 2010 and 2015 in a United Kingdom tertiary vascular center. Demographical and procedural data were obtained for those undergoing percutaneous femoropopliteal angioplasty...

BACKGROUND: The clinical consequences of starting chronic peritoneal dialysis (PD) after emergent dialysis via a temporary hemodialysis (HD) catheter has rarely been evaluated within a full spectrum of treated end-stage renal disease (ESRD). We investigated the longer-term outcomes of patients undergoing emergent-start PD in comparison with that of other practices of PD or HD in a prospective cohort of new-onset ESRD. METHODS: This was a 2-year prospective observational study...

BACKGROUND: Arteriovenous fistula (AVF) is defined as an abnormal communication between the high flow arterial system and the low flow venous network, which directly connects the arterial feeding vessels and the near draining veins without normal intervening capillary bed. Arteriovenous fistula incurs in preauricular region is exceeding rare. Most of these fistulae occur as a result of an iatrogenic injury, the volume is small, feeding and draining vessels of feeding and draining are simple, and can be cured easily...

OBJECTIVE: Current Kidney Disease Outcomes Quality Initiative guidelines do not incorporate age in determining autogenous arteriovenous hemodialysis access placement, and the optimal initial configuration in elderly patients remains controversial. We compared patency, maturation, survival, and complications between several age cohorts (<65 years, 65-79 years, >80 years) to determine whether protocols should be modified to account for advanced age. METHODS: All patients at two teaching hospitals undergoing a first autogenous arteriovenous access creation in either arm between 2007 and 2013 were retrospectively analyzed from a prospectively maintained database...

Arteriovenous malformation in the pancreas is a rare anatomic abnormality that may produce acute pancreatitis. The diagnosis was suspected by computed tomography with intravenous contrast and by magnetic resonance imaging and it was confirmed by arteriography of the celiac trunk and superior mesenteric artery. The treatment received was endovascular, although the other valid option for the treatment of this disease is the surgical resection. The objective of this communication is to present a case of acute pancreatitis due to arteriovenous malformation treated by endovascular approach...

Background: The pathophysiology of a paradoxical systolic blood pressure (SBP) rise during hemodialysis (HD) is not yet fully understood. Recent research indicated that 10% of chronic HD patients suffer from prolonged intradialytic hypoxemia. Since hypoxemia induces a sympathetic response we entertained the hypothesis that peridialytic SBP change is associated with arterial oxygen saturation (SaO 2 ). Methods: We retrospectively analyzed intradialytic SaO 2 and peridialytic SBP change in chronic HD patients with arteriovenous vascular access...

In patients receiving hemodialysis, the provision of safe and effective vascular access using an arteriovenous fistula or graft is regarded as a critical priority by patients and health professionals. Vascular access failure is associated with morbidity and mortality, such that strategies to prevent these outcomes are essential. Inadequate vascular remodeling and neointimal hyperplasia resulting in stenosis and frequently thrombosis are critical to the pathogenesis of access failure. Systemic medical therapies with pleiotropic effects including antiplatelet agents, omega-3 polyunsaturated fatty acids (fish oils), statins, and inhibitors of the renin-angiotensin-aldosterone system (RAAS) may reduce vascular access failure by promoting vascular access maturation and reducing stenosis and thrombosis through antiproliferative, antiaggregatory, anti-inflammatory and vasodilatory effects...

A tailored therapy to patient requirements by combining endovascular and surgical steps can be necessary to prolong the life of a vascular access. Stent grafts play a growing role for the therapy of dialytic access complications. Randomized multi-center trials, however, support the on-label use of stent grafts in the treatment of graft venous outflow and in-stent restenosis. The main contraindication to their use is an ongoing infection. We report two cases of new off-label application of Viabahn (Gore, flagstaff, USA) stent graft...

The arteriovenous fistula (AVF) is the recommended access for most people requiring hemodialysis. Success or failure of cannulation of the AVF greatly impacts the patient's experience. Research suggests that skill development in this area is needed. This scoping review was conducted to review current research on cannulation of the AVF to find strategies to improve successful cannulation. Results of this scoping review (n = 36)demonstrated that most studies can be categorized under the technique of cannulation, and concerns and preferences with the AVF as a consequence of cannulation...

Arteriovenious malformations (AVMs) are associated with significant morbidity and mortality, and have a rupture risk of ~3% per year. Treatment of AVMs must be tailored specifically to the lesion, with surgical resection being the gold standard for small, accessible lesions. Pre-operative embolization of AVMs can reduce nidal blood flow and remove high-risk AVM features such as intranidal or venous aneurysms, thereby simplifying a challenging neurosurgical procedure. Herein, we describe our approach for the staged endovascular embolization and open resection of AVMs, and highlight the advantages of having a comprehensively trained neurovascular surgeon leading a multi-disciplinary clinical team...

For dural arteriovenous fistula (DAVF), when the usual endovascular or neurosurgical approaches are difficult to treat, multi-modal treatment can be helpful. We present a case of a 71-year-old woman with DAVF, who presented with an intracerebral haemorrhage. Digital subtraction angiography revealed a DAVF of the transverse sinus, with cortical venous reflux. Transvenous and transarterial approaches for coil embolization failed. In the operating room, a small craniotomy was performed, and coil embolization was done under fluoroscopy...

Background/Aims: This study aims to demonstrate whether the association between initial vascular access and mortality among hemodialysis patients varies by age. Methods: We conducted a retrospective study that included 2,552 patients who started hemodialysis. Vascular access was divided into three categories: percutaneous catheter, tunneled cuffed catheter, and arteriovenous (AV) access. Results: Survival rates for patients who received a central venous catheter, such as percutaneous or tunneled cuffed catheter, aged 65 to 74 years and those ≥ 75 years were reduced, but not for those aged < 65 years (log-rank test; p < 0...
