회음부 암성 통증 제거를 위해 실시한 외톨이(Impar) 교감신경절 차단 - 증례 보고

The perineum refers to the anatomical area immediately below the pelvis, and is comprised of diverse anatomic and somatic innervation. Although various interventions have been proposed for the management of intractable cancer-related perineal pain, their efficacy are limited because the target of nerve blocks has focused on somatic rather than sympathetic components. Recently, blockade of the ganglion impar has been introduced as an alternative means of managing intractable neoplastic perineal pain of sympathetic origin. We successfully treated a patient who had suffered from cancer-related intractable perineal pain with ganglion impar block. (Korean J Anesthesiol 1997; 33: 750∼752)
