[Intravenous digital subtraction angiography in the detection of spinal angiomas].

In every case in whom the myelogram suggests abnormal vascularity, a spinal arteriogram by means of intravenous DSA is indicated. This should be regarded as a screening method in order to confirm the suspected diagnosis of a spinal angioma and to ascertain its extent. After embolisation or surgery, intravenous DSA is a suitable method for observing the result of the treatment.
