Angiographic diagnosis of aorto-inferior vena caval fistula.
Two cases of spontaneous aorto-caval fistula are reported. In the first, following laparotomy for an erroneous diagnosis of acute appendicitis, retrograde aortography was conclusive. In the second case, an attempted renal angiogram for acute renal failure and hematuria failed but a flush aortic injection showed the fistula.
The sidewinder catheter for extra cranial angiography: technical, diagnostic and therapeutic applications.
Through using the sidewinder catheter system for visceral angiography in over 200 patients we have improved our success rate. The method is simple and safe, and we recommend it.

Diagnostic accuracy of cerebral angiography and computerized transaxial tomography.
Computer tomography (CT) of the brain has become widely accepted as an accurate method of studying a variety of intracranial diseases. In a prospective controlled study one group of radiologists interpreted cerebral angiograms and another interpreted CT studies undertaken in the same patients. The overall rates of diagnostic accuracy were similar (81 and 84% for angiography and CT, respectively), albeit less than reported in the literature, and thus support the contention that CT scanning should be available as the initial neuroradiologic examination whenever possible.
Normal-pressure hydrocephalus due to tentorial meningioma.
Normal-pressure hydrocephalus and the associated triad of dementia, apraxic gait and urinary incontinence may be casued by various, sometimes unsuspected, lesions, usually those that block the flow of cerebrospinal fluid (CSF) around the tentorium. A 58-year-old woman with insidious onset of behaviour and gait problems had occult, normal-pressure hydrocephalus and a tentorial meningioma, resection of which produced complete recovery. This case demonstrates that a distinction must be made between the syndrome of normal-pressure hydrocephalus resulting from disturbance in CSF dynamics and the pathophysiologic features of the underlying lesion.

The role of angiography in the management of intestinal carcinoid.
Carcinoid tumors of the intestine may present with bowel obstruction or with the carcinoid syndrome. Confirmation of the diagnosis by biochemical means is easy. Management is often surgical and a number of different procedures have been advocated, e.g. resection of the primary, hemicolectomy and lately, partial hepatectomy. The angiographic features of two cases are presented and discussed; the usefulness of the information so gleaned in the choice of management is stressed.
