Sixty-one consecutive patients, less than or equal to 40 years old, were hospitalized for cerebral infarction between 1977 and 1985. Evaluation included computed tomographic brain scan, arteriography, echocardiography, and blood tests. A probable migrainous infarction was diagnosed in six patients (10%) (all women with a history of migraine) who survived the initial stroke and were followed-up for an average of four years. In five patients the stroke occurred during a common migraine attack and in one patient during a classic migraine attack. The site of infarction was invariably the occipital lobe. During the follow-up, no subject had a further stroke. All six women had a permanent hemianopic deficit.

This study analyzed 76 consecutive patients with carotid transient ischemic attacks (TIA) and carotid lesions appropriate to symptoms who underwent endarterectomy during the period 1975–1981. The mean age of the patients was 51.9 ± 8 years at the time of surgery. Hypertension was present in 32.9%, diabetes mellitus in 13%, ischemic cardiopathy in 8.2% and peripheral vascular disease in 6.6%. Operative mortality was 1.3% and harder morbidity 4%. The average follow-up was 2.6 years (range 1–7 years). The observed 5-year survival rate was 85.2% compared to the expected rate of 92.4% in a normal population. During the follow-up 5 patients had a stroke: the cumulative stroke rate was 4.6% at 1 year and 7.9% at 3 years. 18 patients had further TIAs (13 carotid TIAs and 5 vertebro-basilar TIAs). 6 patients suffered myocardial infarction. The prognosis of TIA patients treated with endarterectomy is difficult to evaluate because the natural history of TIAs is still undefined.
