Obstetric injury is the most frequent cause of acquired rectovaginal fistulas but infection and other forms of trauma may also result in these fistulas. After an obstetric injury, the fistula may be manifest immediately but more frequently appears 7–10 days after delivery. Fistulas occur most often after a thirdor fourth-degree laceration. Inadequate repair, breakdown of the repair, or infectio...

BACKGROUND Magnetic resonance imaging (MRI) is highly accurate for the depiction of both the primary tract of fistula and abscesses, in patients with perianal disease. In addition, MRI can be used to evaluate the activity of fistulas, which is a significant factor for determining the therapeutic strategy. OBJECTIVES This study aimed to determine the usefulness of diffusion-weighted (DW) MRI f...

Introduction: The aim of the present study was to determine direct effects of NO modulation on protective electrophysiological properties of atrioventricular node (AV node) in the experimental model of AF in rabbit. Methods: Isolated perfused rabbit AV nodal preparations were used in two groups. In the first group (N=7), LNAME (50μM) was applied. In the second group (N=12), different concent...

AIM To establish and evaluate an experimental porcine model of fistula-in-ano. METHODS Twelve healthy pigs were randomly divided into two groups. Under general anesthesia, the experimental group underwent rubber band ligation surgery, and the control group underwent an artificial damage technique. Clinical magnetic resonance imaging (MRI) and histopathological evaluation were performed on the...

Introduction: Renal Replacement Therapy is the treatment modality for chronic kidney disease (CKD) which ranges from hemodialysis, peritoneal dialysis to renal transplantation, latter being best form of treatment. But, transplantation available at limited centers only so hemodialysis most commonly used requires a vascular access. But there are surgeons in region arterio-venous (AV) fistulas rec...

The paper proposes a new metadata model (VandA) directed to support innovative exploitation of Historical AV Archives content. After an analysis of the needs of traditional and potential users, the model is illustrated through running examples to show at what extent the new usages can be supported.

CORONARY ARTERY FISTULAS, precapillary communications between a coronary artery and a cardiac chamber or vessel, have been described as the most common hemodynamically significant congenital coronary anomaly.' In a review of 21 original cases and 342 previous cases, Levin et al.' reported that coronary fistulas originated slightly more often from the right than from the left coronary artery, bu...

This is a post-hoc analysis of the results Lutonix AV Global Registry (outside United Sates) focusing exclusively on arteriovenous fistulas (AVFs) with inclusion criteria consistent to those IDE trial from States. Device under investigation was drug-coated balloon (DCB). 131 320 subjects met for in analysis. 59.5% (78/131) were male. 50.5% white and 45.7% Asian population. Among exploratory out...

traumatic coronary artery-cameral fistulas (tcaf) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery fistulas. we report the case of a 17-year-old man who presented with left anterior descending coronary artery-right ventricle fistula following pe...

Coronary artery fistulas are one of the most common congenital anomalies of the coronary arteries. Most fistulas are small and of no clinical significance, although larger or multiple fistulas can be symptomatic and produce complications. Early percutaneous occlusion is now always recommended, and surgical closure is restricted to use for multiple or large fistulas. Here we report four cases of...
