Arteriovenous fistulas of the placenta are extremely rare in singleton pregnancies and, to our knowledge, have not previously been reported in twin gestations. We describe a case of an arteriovenous fistula of the placenta in a diamniotic-monochorionic twin pregnancy complicated by twin-to-twin transfusion syndrome (TTTS). The arteriovenous fistula was demonstrated by color-coded vascular injec...

BACKGROUND Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. CASE PRESENTATION Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out other...

Embolization of type I perimedullary spinal arteriovenous fistulas (AVFs) can be difficult, because of tortuosity and the small diameter of the feeder and distal location of the fistula site. The 1.5F flow-directed catheter in conjunction with a hydrophilic guidewire has been used in fistula embolization with cyanoacrylate glue for spinal vascular malformations at our institution. This combinat...

A seven-month-old infant presented with a generalized seizure. The radiological evaluation revealed a large arteriovenous fistula in the left sylvian region. The fistula connected the left middle cerebral artery and the vein of Trolard. A giant varix was present at the venous end. The child underwent craniotomy, complete disconnection of the fistula and excision of the varix. Except for recurre...

Background. With this case report the authors wish to present the accuracy of non-invasive vascular imaging methods, especially Doppler ultrasound, in the evaluation of the muscular trauma and periskeletal soft tissue vascular anomalies. Case report. Twelve year-old boy has been admitted with the right femoral quadriceps muscle traumatic rupture. Postoperative B-mod sonography (US) visualised r...

Introduction: Patients with end stage renal disease require hemodialysis. Radiocephalic arteriovenous fistula is the main choice of vascular access in patients who undergo hemodialysis procedure. Physiological vein distensibility an important aspect forming a mature fistula. This study aims to analyze correlation between preoperative and maturation. Method: Data are collected from Hasan Sadikin...

Spinal dural arteriovenous fistula is a rare vascular lesion of the spinal cord associated with progressive myelopathy. Symptoms include progressive gait dysfunction, weakness, sensory loss, and bowel and bladder dysfunction. Because these symptoms overlap with other common causes of myelopathy and the disease is rare, spinal dural arteriovenous fistula is often not suspected and the time to di...

BACKGROUND Conventional wisdom suggests that vascular interposition flaps are helpful in the treatment of all patients with vesicovaginal fistulas. Complicated fistulas are often treated with interposition omental flaps; however, failed omental flap repairs have not been described without the use of another interposition flap. CASE A 52-year-old woman with a history of cystotomy repair at the...

Moyamoya vascular pattern and dural arteriovenous fistula (dAVF) are rare vascular abnormalities and both can be secondary to head trauma. The role of dural angiogenesis in the pathophysiology of vascular malformation is rather unclear. We report a unique case of moyamoya vasculopathy simultaneously associated with dAVF after heavy head trauma. It seems that both moyamoya syndrome and dAVFs are...

Background One of the mandates of the Canadian Society of Nephrology's (CSN) Vascular Access Working Group (VAWG) is to inform the nephrology community of the current status of vascular access (VA) practice within Canada. To better understand VA practice patterns across Canada, the CSN VAWG conducted a national survey. Objectives (1) To inform on VA practice patterns, including fistula creati...
