Intra-articular joint capsule injection is a common method used to control postoperative pain as a result of primary total knee arthroplasty (TKA). It is generally considered a safe practice and is highly effective in reducing the need for postoperative opioid administration as well as decreasing recovery time through early mobilization. However, any injection into the posterior knee space has ...
We describe two patients who presented with dementia as the primary neurological manifestation of their dural arteriovenous fistula (dAVF). Although dementia is not the most common presentation for a dAVF, these cases show that obliterating the fistula can eliminate this dreadful manifestation. This awareness may facilitate the diagnosis of dementia in cases caused by dAVF and allow for a minim...
BACKGROUND AND PURPOSE Time-resolved 3D-DSA (4D-DSA) enables viewing vasculature from any desired angle and time frame. We investigated whether these advantages may facilitate treatment planning and the feasibility of using 4D-DSA as a single imaging technique in AVM/dural arteriovenous fistula radiosurgery. MATERIALS AND METHODS Twenty consecutive patients (8 dural arteriovenous fistulas and...
Congenital arteriovenous communications involving the external carotid artery and jugular veins are rare. We report a 4-year-old girl with a history of an abnormal audible sound in the right ear during sleep. Physical examination revealed a carotid bruit, thrill and a pulsatile mass in the right neck. A simple congenital right external carotid-jugular arteriovenous fistula was confirmed and suc...
Introduction: Patients with kidney failure undergoing hemodialysis are frequently exposed to the hemodialysis needles are inserted into the arteriovenous fistulas; one of the important interventions in nursing care is use of nonpharmacological interventions for relief pain. Therefore, this study was conducted to compare the effect of cryotherapy and acupressure on the pain intensity of needle ...
A 74-year-old man with hypertension and peripheral vasculopathy historywas admitted to our hospital to start renal substitutive treatment with haemodialysis through a functioning right humeral-cephalic arteriovenous fistula. In the first week after starting haemodialysis, the patient presented signs of distal ischaemia in the second and third fingers. A fistulography confirmed distal steal by a...
Arteriovenous graft for hemodialysis vascular access is a widely used technique with many advantages. However, it has crucial complications with graft thrombosis and infection. We recently experienced an unusual case of arteriovenous graft complication involving graft thrombosis related to fistula formation between the graft and the natural vein with infection. We diagnosed this condition using...
We present a case of developmental venous anomaly associated with arteriovenous fistula supplied by a single arterial feeder adjacent to a large acute intracerebral hemorrhage. The arteriovenous fistula was successfully obliterated by superselective embolization while completely preserving the developmental venous anomaly. Two similar cases, including superselective angiographic findings, have ...
Five patients with previous experience of home haemodialysis (lasting one to two years) had internal arteriovenous fistulae created in a previously non-cannulated limb. After training of the spouses or patients to insert the needles, the arteriovenous cannulas were removed and the patients maintained on fistula dialysis in the home, unattended, overnight, for periods of 1 to 11 months (total pa...
Vascular access stenosis is a major complication in hemodialysis patients. We prospectively observed 50 patients in whom 50 nitinol shape-memory alloy-recoverable technology (SMART) stents were used as salvage therapy for recurrent peripheral venous stenosis. Twenty-five stents each were deployed in native arteriovenous fistula (AVF) and synthetic arteriovenous polyurethane graft (AVG) cases. V...
