The significance of internal carotid artery occlusion shown by i.v. digital subtraction angiography.

A retrospective review of 493 IV digital subtraction angiography examinations performed for cervicocerebral vascular disease revealed 27 apparent occlusions of the internal carotid artery. We identified 20 patients whose occlusions did not warrant further investigation. Fourteen occlusions were on the asymptomatic side, two were in patients who preferred medical treatment, two were in patients unsuitable for carotid endarterectomy, and two patients with bihemispheric transient ischemic attacks were treated for the contralateral carotid. Four very tight stenoses were found in the other seven patients, one of whom refused endarterectomy. As the signs of a very tight stenosis are subtle, and the number of such stenoses that are treatable is low (three in 493), cerebral angiography is justified in doubtful cases to avoid missing potentially treatable lesions.

Amnesia after femorocerebral angiography.

The charts and radiographs of 12 of 1,520 patients who developed amnesia after transfemoral cerebral angiography performed with local anesthesia and minimal sedation were retrospectively reviewed. In three younger patients, exacerbation of organic or idiopathic temporal lobe epilepsy was thought to be the cause of the amnesia, while the amnesia of the nine patients over 40 years old had the characteristics of transient global amnesia. Eight of the patients had had similar episodes before angiography, and three others had other evidence of vertebrobasilar disease. Emboli from atheromatous debris or catheter clot due either to catheter manipulation problems, an inexperienced operator, or the use of a large catheter were considered likely causes in 11 cases, while in three patients contrast emboli or toxicity may have been the etiologic factor.
