Dural arteriovenous fistulas are acquired lesions that usually involve the dura around the cavernous sinus. The transverse, sigmoid, and superior sagittal sinuses may be affected occasionally. With the exception of bilateral cavernous sinus dural arteriovenous fistulas, the simultaneous occurrence of dural arteriovenous fistulas at two locations is rare. Among 105 patients evaluated for dural a...

Aim. This study aspires to assess the role of 3D-Endoanal Ultrasound (3D-EAUS) and Magnetic Resonance Imaging (MRI) in preoperative evaluation of the primary tract and internal opening of perianal fistulas, of secondary extensions and abscess. Methods. During 2014, 51 Crohn's disease patients suspected for perianal fistula were enrolled. All patients underwent physical examination with both the...

PURPOSE The aim of this paper is to report our experience in the creation of arteriovenous fistulas in children by using microsurgical vascular techniques, with emphasis on the details of the surgical technique. METHODS The children underwent surgery from July 1997 to March 2004. Operating loupes (magnification: 3.5X) were used by the entire surgical team. After dissection and adequate mobili...

Aim. Genitourinary fistulas are bothersome clinical entities not only for the patient but also for the treating surgeon as well. A lot of surgical procedures have been proposed; however, most of the fistulas can be easily treated with plain surgical techniques, such as the simple surgical closure of the fistula tract. Material and Method. The study was carried out in the urogynecology departmen...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit a...

Arteriovenous fistulas are widely used for hemodialysis patients with end-stage renal failure. Due to the lack of suitable veins because of the arteriovenous fistulas previously opened in the upper extremity, alternative access routes are being tested. Few complications of long-term alternative arteriovenous fistulas have been reported in the literature. We report the results of surgical repair...
