[Angioscintigraphy in the study of cerebrovascular accidents (author's transl)].

The Authors analyse the results of cerebral angioscintigraphy, performed with gamma camera on-line with a MED II system, in 158 cases of ischemic stroke, 13 cases of hemorragic stroke and 29 cases of cerebral neoplasm. 84 cases of ischemic stroke and all the cases of hemorragic stroke and neoplasm had contrast angiography. The dynamic study has provided additional information in 51.3% of the cases of ischemic stroke (63.7% when the internal carotid artery involvement alone is considered), in 84.6% of the cases of hemorragic stroke and in 58.6% of the neoplasm cases. The same information moreover is almost always able to clarify the cause of the positive rectilinear brain scans, frequently uncertain in strokes. In cases of ischemic stroke correlations are considered between angiography and angioscintigraphy. In particular the value of the method is discussed as a screening procedure for the detection of extra-cranial vascular disorders, amenable of surgical therapy. The authors conclude that angioscintigraphy is the method that, separately considered, provides most of the useful information in the diagnosis of stroke.
