INTRODUCTION AND OBJECTIVES A great variety of different types of vascular fistula are referred to cardiac catheterization laboratories for diagnosis and percutaneous occlusion. In addition, a wide range of devices is available for treating them percutaneously. The objectives of this study were to assess the usefulness and difficulty of treating vascular fistulas percutaneously using controlled...

PURPOSE To determine the efficacy of porous metallic stents in the treatment of experimentally created carotid-jugular fistulas. METHODS Carotid-jugular fistulas were constructed surgically in five mongrel dogs. Porous metallic stents were placed endovascularly across the fistula holes within the carotid artery; carotid angiography was performed before, immediately after, and 1 and 2 months a...

OBJECTIVE To evaluate the use of cardiovascular magnetic resonance (CMR) to visualize angiographically-detected congenital coronary artery fistulas in adults. METHODS CMR techniques were used to study 13 patients, recruited from the Dutch Registry, with previously angiographically diagnosed fistulas. RESULTS Coronary fistulas were detected in 10 of 13 (77%) patients by CMR and, retrospectiv...

Of the 185 carotid and vertebral fistulas treated by the authors over the past 10 years, five developed neurologic deficits after abrupt closure of their fistulas. The earliest case, treated initially by proximal surgical carotid occlusion, presented 32 years later with cerebral steal symptoms from the large, long-standing carotid cavernous fistula. Upon completion of a surgical trapping proced...

Fistulas in the tracheobronchial tree (bronchopleural and tracheoesophageal fistulas) have a multifactorial etiology and present a variable incidence in the literature. In general, the related morbidity and mortality are high. Once such a fistula has been diagnosed, surgical closure is formally indicated. However, the clinical status of affected patients is usually unfavorable, which precludes ...

Coronary artery fistula is an anomaly in which a coronary artery directly connects to a cardiac chamber or great vessel. Its incidence is around 0.1 to 1% in the adult population. Dual coronary artery fistulas are far less common and their incidence is estimated to be around 5% in patients with this anomaly. Closure of the fistulas is indicated in patients with myocardial ischemia, large left t...

We describe the case of a 45-year-old female patient with coronary fistulas arising from both the left and right coronary artery system and emptying in the left ventricle. Only sporadically do coronary artery fistulas drain into the left ventricle. In our patient, the most likely explanation of the fistulous communications was a congenital cause. We review the literature on coronary cameral fis...

PURPOSE To present the results of our treatment of dural cavernous sinus fistulas with surgical exposure of the superior ophthalmic vein (SOV), retrograde venous catheterization, and coil embolization of the cavernous sinus. METHODS Twelve patients with dural cavernous sinus fistulas were treated via a retrograde transvenous SOV approach in our hospital during a 3-year period. All patients ha...

Acne vulgaris (AV) is a common skin disease that causes physical and psychological problems for affected individual. In addition to systemic changes in hormone levels, overproduction of local steroids, especially androgens are associated with AV. Cytochrome (CYP) 19 is involved in the synthesis of estrogens. The aim of the present study was to investigate the influence of CYP19A

BACKGROUND Enterocutaneous fistulas are a serious complication of Crohn's disease and are difficult to treat. Infliximab, a chimeric monoclonal antibody to tumor necrosis factor alpha, has recently been developed as a treatment for Crohn's disease. We conducted a randomized, multicenter, double-blind, placebo-controlled trial of infliximab for the treatment of fistulas in patients with Crohn's ...
