✓ An arteriovenous malformation of the spinal cord was successfully obliterated by a percutaneous transcatheter technique using isobutyl 2-cyanoacrylate.
Arteriograms of 12 patients with space-occupying lesions involving the thalamus were compared with 100 vertebral and carotid arteriograms reported as normal. It was found that masses that involve the thalamus primarily or secondarily affect the choroidal arteries in a characteristic manner. The most commonly involved vessel is the lateral posterior choroidal artery. The medial posterior choroidal artery may also be affected because of its contribution to the dorsal medial nucleus of the thalamus and its occasional course around the pulvinar. Because the anterior choroidal artery is reciprocal in size to the lateral posterior choroidal artery, the lesion will often be demonstrated on carotid angiography.KEY WoaDs thalamus brain tumor ehoroidal artery angiography 1.
The authors review 47 patients with closed-head injuries requiring treatment for acute subdural hematoma and report that 21 (45%) survived for 5 days or more. Follow-up study of these 21 survivors led to the following observations: that clinical evaluation of these patients is the most reliable index of their postoperative progress; that the diagnostic usefulness of postoperative cerebral arteriograms is limited because immediate postoperative changes tend to persist; that craniotomy is preferable to burr holes for removal of an acute hematoma; and that the value of cisternography, unless done serially, is limited since posttraumatic hydrocephalus develops rapidly and may persist indefinitely.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
