Paravertebral block is commonly used in the treatment for acute and chronic pain. The duration of paravertebral block could theoretically be prolonged with neurolytic agents. We report two cases of ultrasound-guided neurolytic paravertebral blocks in patients suffering from intense cancer-related thoracic pain. Ultrasound was used to identify the space and plane of injection at the mid-thoracic level. Absolute alcohol was used to block the nerves at different segments. The two patients had great pain relief. Neurolytic paravertebral block can be a useful technique in patients with intractable cancer pain. Because of the risk of complication, it is recommended that this technique should be limited to relief of intractable pain in cancer patients with a poor prognosis.
椎旁阻滞常用于急慢性疼痛的治疗。理论上，使用神经溶解剂可延长椎旁阻滞的持续时间。我们报告了两例超声引导下对患有严重癌症相关胸痛患者进行神经溶解椎旁阻滞的病例。使用超声确定胸段中部的注射间隙和平面。使用无水乙醇对不同节段的神经进行阻滞。这两名患者的疼痛得到了极大缓解。神经溶解椎旁阻滞对于患有顽固性癌症疼痛的患者可能是一种有用的技术。由于存在并发症风险，建议将该技术仅限于缓解预后较差的癌症患者的顽固性疼痛。
