Carotid Artery Thrombosis

Progressing stroke. Angiographic aspects.

Progressing strokes were noted in 17 of 256 patients who underwent surgery for atheromatous disease involving the internal carotid artery. This disorder was characterized by an active increase in the neurologic deficit during an 18- to 24-hour period. Although angiographic findings were neither specific for this type of cerebrovascular disease nor uniformly present, the angiography did indicate that not only embolization of the cerebral leptomeningeal conducting vessels but also collaterization through them was a pertinent mechanism.

Cerebral vasospasm and ruptured intracranial aneurysm.

The literature concerning cerebral vasospasm associated with subarachnoid hemorrhage (SAH) due to ruptured intracranial aneurysm contains no definitive study of patients to determine whether there is (1) any clinical picture consistently present coincident with known cerebral vasospasm, (2) any relationship between mortality and known vasospasm, and (3) any relationship between serious brain damage (morbidity) and known vasospasm. To answer these important questions, experience with 198 consecutive acute SAH patients (every patient had a cerebral angiogram demonstrating one or more intracranial aneurysms) was studied. The experience with these 198 consecutive patients led to the conclusions that (1) there is no clinical picture consistently present coincident with known cerebral vasospasm; (2) cerebral vasospasm has no effect on the mortality from SAH due to ruptured aneurysm; and (3) there is no relationship between the frequency and severity of the complications from surgical or conservative treatment and the presence or absence of vasospasm.

Adolescent

Temporal profile (clinical course) of acute carotid system cerebral infarction.

The records of 179 consecutive patients with acute carotid system cerebral infarction were studied to describe the temporal profile of the clinical events during the first week of the illness. Only those patients admitted to the cerebrovascular hospital service within 36 hours of the onset of the first symptom were included. The neurological status of 39% was stable (unchanged) at the end of seven days; 35% of the patients gradually improved. Nineteen percent had a progressing neurological deficit from the onset which stabilized within 48 hours of onset. Six patients (3%) had a remitting-relapsing course during the first 36 hours. Eight patients (4%) had a significant late worsening, after 48 hours of stable or improving course. Mortality was 11% for the entire group. However, a high risk of death group was identified - the mortality was 41% for those patients who had any degree of decreased level of consciousness and hemiplegia at the time of admission.
