The Journal of Vascular Access, 2014
Multiple superficial veins in different anatomical configurations exist in the elbow. The resulting variety of elbow arteriovenous fistulae (AVFs) is described in this paper. A classification of elbow AVF in nontransposed AVF, transposed AVF and multiple outflow AVF is proposed. The nontransposed brachiocephalic AVF has the lowest primary failure rate

Neurosurgery Clinics of North America
Dural arteriovenous fistulas are rare cerebrovascular lesions arising from abnormal connections between an artery and a vein. Though rare, high-grade aggressive lesions can cause hemorrhagic events and non-hemorrhagic neurologic deficits if left untreated.

Coronary Arteriovenous Fistula
Scandinavian Journal of Thoracic and Cardiovascular Surgery, 1969A coronary artery fistula to the coronary sinus in a 58-year-old woman with angina pectoris is described. Two big fistulas from the right coronary artery had a common opening which was closed with 5 mattress sutures buffered with teflon pearls and a dacron patch.

HEPATOPORTAL ARTERIOVENOUS FISTULA
Journal of the American Medical Association, 1954One of the most hazardous types of bleeding from the gastrointestinal tract is that occurring from esophageal or gastric varices. Such varices usually arise following an obstruction to the return of portal blood to the systemic venous system. There are two common types of portal obstruction: that occurring in the liver—the so-called intrahepatic type ...

Urology, 1976
A review of the literature reveals that aggressive treatment of symptomatic intrarenal arteriovenous fistulas, whether by surgical or radiologic techniques, is generally indicated. The exception is those fistulas which result from closed renal biopsy since these usually heal spontaneously.

Clinical Neuroradiology, 2009
Spontaneous dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous shunts within the dura mater of the sinuses. The exact etiology remains uncertain. Arterial feeder derive from the meningeal branches in the region. The clinical symptoms are highly dependent on the venous drainage.

Occipital arteriovenous fistulae
Head & Neck Surgery, 1985AbstractOccipital arteriovenous fistulae may be congenital or traumatic. The distinguishing characteristics of each and diagnosis by dynamic computed tomographic (CT) scanning, obviating the need for angiography, is outlined and illustrated by a case report. The indications for surgery and operative approach are discussed.

Alternatives to arteriovenous fistulas
BMJ, 2014In their review, Siddiky and colleagues suggest that arteriovenous fistulas for haemodialysis “offer the best short, intermediate and long term options for renal replacement therapy.”1 Although they have many advantages, one of the few rigorous systematic reviews in vascular access emphasises the often overlooked complication of primary non-function ...

Arteriovenous Fistula of the Lung
Radiology, 1959Pulmonary arteriovenous fistulas are anomalous connections between the arteries and veins of a portion of the pulmonary vascular bed. Since the first clinical diagnosis of pulmonary arteriovenous fistula by Smith and Horton in 1939 (13), 200 cases have been reported.

Traumatic arteriovenous fistulae
Injury, 1975Twenty-two cases of arteriovenous fistulae are reviewed retrospectively, with particular emphasis on their clinical presentation, physical signs, investigations and management. This review allows us to make certain conclusions for the future diagnosis and management of this condition.
