To evaluate the use of superior hypogastric plexus block with computed tomographic (CT) guidance in patients with endometriosis and chronic pelvic pain.
Seven blocks were performed on an outpatient basis in five women with endometriosis and pelvic pain. In the first four patients, one or two 20-gauge, 15-cm needles were placed anterior to the spine at the common iliac bifurcation from a posterior approach. In the fifth patient, the block was performed from an anterior approach with a single needle.
One procedure resulted in mild pain relief, three in considerable pain relief, one in complete midline pain relief with no change in the lateral pain, and one in complete pain relief. One procedure was terminated because anesthetic was injected into the peritoneal cavity. There were no other complications.
CT-guided superior hypogastric plexus block is easily performed and can be used to assess whether chronic pelvic pain can be attenuated by blocking the superior hypogastric plexus.
评估在子宫内膜异位症和慢性盆腔疼痛患者中，在计算机断层扫描（CT）引导下进行上腹下丛阻滞的应用情况。
对5例患有子宫内膜异位症和盆腔疼痛的女性患者在门诊进行了7次阻滞。在前4例患者中，从后路在髂总动脉分叉处脊柱前方置入1或2根20G、15cm的穿刺针。在第5例患者中，从前路用单根穿刺针进行阻滞。
1例患者疼痛轻度缓解，3例显著缓解，1例中线疼痛完全缓解但侧方疼痛无变化，1例疼痛完全缓解。1例操作因麻醉药注入腹腔而终止。无其他并发症。
CT引导下的上腹下丛阻滞操作简便，可用于评估通过阻滞上腹下丛能否减轻慢性盆腔疼痛。
