An animal model for a high-flow, aorta-to-vena cava fistula has been developed using microsurgical techniques in the rat. This model provides a means for histopathologic and angiographic evaluation of the natural evolution of major vessel, artery to vein fistulae. Data obtained from such a model may have relevance to the successful treatment of high-flow, head and neck fistulae using detachable...

Coronary artery fistula (CAF) is an abnormal communication between an epicardial coronary artery and a single or multiple cardiac chambers, large vessels or other vascular structures (1). Although it is a rare condition, it is the most frequent congenital coronary anomaly (2), and it accounts for 0.2-0.4% of congenital cardiac anomalies. Approximately 50% of pediatric coronary vasculature anoma...

BACKGROUND Bisphosphonates‎ inhibit osteoclasts, prevent bone resorption and decrease bone turnover. This study examined radiography finding in bisphosphonate-associated osteonecrosis of jaws. MATERIALS AND METHODS This is a retrospective series of 12 clinically diagnosed patients between 7 to 21 year old (average 13 years). They required emergency dental conditions requiring management by de...

Actinomycosis is a chronic granulomatous infection caused by Actinomyces species which may involve only soft tissue or bone or the two together. Actinomycotic osteomyelitis of maxilla is relatively rare when compared to mandible. These are normal commensals and become pathogens when they gain entry into tissue layers and bone where they establish and maintain an anaerobic environment with exten...

Perianal fistula is a very common problem in general population. Ninety percent of perianal fistulae arise from infected anal glands, and they often give rise to perianal abscesses. Very rarely perianal fistulae and abscesses undergo malignant transformation and give rise to carcinomas, mainly adenocarcinomas. We are reporting a case of squamous cell carcinoma arising from long-standing periana...

Multiple coronary artery-left ventricular fistulae involving all three major coronary arteries are extremely rare. Clinical findings are heterogeneous but include a history of typical or atypical angina pectoris in most cases. Coronary arteriography in a 65 year old woman who presented with chest pain at rest revealed multiple fine fistulae arising from the left anterior descending, left circum...

Se presenta caso paciente sexo femenino 34 años edad, historia 2 meses evolución tumefacción crecimiento progresivo en región seno maxilar izquierdo acompañado rinor...

Nursing care to patients after total laryngectomy should be based on scientific knowledge. Evidence-based practice is a type of approach that stimulates the use of research results in clinical practice. This study presents a systematic review that aimed to identify the main treatments for pharyngocutaneous fistulae after total laryngectomy. Articles were selected from five databases: Pubmed, Ci...
