The appearance of a benign fistula between the airway and the gastrointestinal tract is a rare complication of esophagectomy. We report a patient with neo-esophago-bronchial fistula that developed 13 months after two-stage esophagectomy. Repeat thoracotomy was not deemed appropriate given the patient's chronic sepsis and malnutrition. After unsuccessful attempts at endoscopic closure, the fistu...

Oronasal fistula is a relatively common complication associated with maxillary canine tooth extraction, problematic healing of maxillectomy, and repair of secondary cleft palate in small animals. Regardless of the clinical scenario associated with oronasal fistula, therapy requires surgical treatment. Principles for surgical repair of oronasal fistula include development of mucosal flaps with e...

Haemodialysis vascular access patency is severely compromised by fistula non-maturation and access stenosis. Intimal hyperplasia (IH) is considered the culprit lesion in failed fistulas, resulting in luminal narrowing and stenosis. This review focuses on the biology and pathophysiology of fistula failure and highlights not only the classically associated IH but also some relatively neglected bu...

We present the first case of an arteriovenous fistula after an all-inside anterior cruciate ligament (ACL) reconstruction. A seventeen-year-old boy had an uneventful ACL reconstruction. Four weeks after surgery, the patient was seen with a pulsating swelling at the lateral distal upper leg. Vascular consultation led to the diagnosis of pseudoaneurysm and arteriovenous fistula of the lateral sup...

Spontaneous vertebral arteriovenous fistulae (AVF) associated with neurofibromatosis Type 1 (NF-1) is a rare occurrence in the previous reports. We presented two female NF-1 patients with a diagnosis of cervical vertebral AVF treated with endovascular approach. The fistula in the first case was successfully obliterated by feeder occlusion; whereas, for the second one, new fistulae were formed f...

common autosomal-dominant genetic disorders with an incidence of approximately 1:3,500. Vascular abnormalities associated with NF-1 include stenotic or occlusive diseases, aneurysms, arteriovenous malformations and, rarely, arteriovenous fistula (AVF). Association of arteriovenous fistula with NF-1 is rare with a few cases of vertebral AVF having been reported (1-3). Endovascular occlusion of t...

BACKGROUND Frequent hemodialysis (HD) may be associated with an increased risk of vascular access complications. Studies addressing vascular access outcomes in frequent HD show conflicting results. METHODS We searched Medline for trials looking at vascular access outcomes in frequent HD. RESULTS Nineteen studies met the inclusion criteria; only studies with a control group were included for...

INTRODUCTION Arteriovenous (AV) fistula failure is a major clinical problem for the 350,000 patients currently on hemodialysis in the United States. The reasons for this failure are mainly attributed to venous stenosis due to neointimal hyperplasia together with a possible failure of vascular dilatation [1]. Despite the magnitude of the clinical problem, there are currently no effective therapi...

Background: Cassia fistula was used traditionally as laxative in pregnant women. Nevertheless, its fetal and maternal effects in pregnancy have not been studied yet. Methods: Oral (Lethal Dose, 50%) LD50 was determined in mice. In addition, a control group, pregnant rats in other 5 experimental groups (n=12) received orally C. fistula aqueous extract (500, 1000 and 2000 mg/kg), tween80 (10%) a...
