Direct surgical intervention of arteriorvenous malformations (AVMs) in functional areas has been accepted as a standard mode of treatment. However, safe and successful intervention requires that such factors as exact location, size, vascular supply, and drainage be considered. Importantly, surgical techniques must be individualized to each patient, based on(More)
PURPOSE To determine the safety, in our practice, of allowing patient preference to influence the timing of antiepileptic drug (AED) reduction, once they became seizure-free after anterior temporal lobectomy (ATL). METHODS Thirty patients underwent anterior temporal lobectomy for medically intractable complex partial epilepsy at Loma Linda University(More)
Somatosensory evoked potentials and redox (reduction/oxidation ratio) of cytochrome a,a3 were studied simultaneously before, during, and after controlled hypotension used for arteriovenous malformation resection. These studies were also conducted before and after ED-IC (external-internal carotid) bypass procedures for treatment of patients with transient(More)
Controlled hypotension is a safe and convenient means of allowing a surgeon to perform intracranial aneurysm, arteriovenous malformation and vascular tumor surgery. The mean arterial pressure between 40 and 60 mmHg induces diminished pulsatile arterial pressure, thus preventing rupture of these abnormal vasculatures. It is still possible to maintain(More)
Fibromuscular dysplasia is a noninflammatory segmental disease of the arteries, of unknown origin. While the renal arteries are most commonly affected, other larger vessels, including the carotid and vertebrals, may be involved. Fibromuscular dysplasia has been implicated as a cause of stroke in adults and (on rare occasions) in children. The classic(More)
