Digital subtraction arteriography for spinal arteriovenous malformation.

Selective spinal cord angiography is the estab lished method for evaluating patients with vascular lesions of the cord. This technique is technically demanding , and the examination takes considerab le amounts of time and rad iation [1]. Digital subtraction angiography (DSA) with venous injections produces arterial images with dec reased patient risk . This procedure is also valuable in conjunction with direct arterial catheterization [2]. DSA was used to study the spinal cord in a patient with a spinal arteriovenous malformation (AVM).
