측두엽 간질에 있어서 선택적인 후대뇌동맥 Sodium Amytal 검사 2례

Abstract

Wada test has been used as the presurgical evaluation method of memory function in epileptic patient. We report experiences with selective posterior cerebral artery sodium amytal test in two intractable temporal lobe epilepsy patients who showed poor performance in conventional Wada test for the presurgical evaluation. Our procedure consisted of injection of sodium amytal via a microcatheter into the P1 distal segment of the posterior cerebral artery and verbal and visual memory test before and after the injection. We also performed Tc-99m ECD SPECT during the procedure. In one patient showed good memory function during the procedure so operation was performed. But the other patient showed poor memory function so we discharged him without operation. Key Words : Temporal lobe epilepsy, Sodium amytal, Wada test
