Angiography and computed tomography in the evaluation of cerebral venous malformations.

The information obtained by computed tomography (CT) and cerebral angiography is compared in eight cases of cerebral venous malformation. Angiography was found to be more reliable for detecting the presence and specific nature of these malformations. Pathological and radiographic differential features between the various forms of cerebral vascular malformations are discussed.

Complete obliteration of a carotid cavernous fistula with sparing of the carotid blood flow using a detachable balloon catheter.

A detachable balloon catheter system is described which has several distinct advantages over pre-existing methods of "intervention radiology". It is anticipated that further refinements in this technique will continue to expand the uses for this procedure.

A simple catheter curve for cerebral angiography.

A simple catheter curve for use in cerebral angiography is discussed. A shorter length of guide wire is needed before the catheter tip will enter the vessel.
