Patients were randomly assigned to Group A (122 patients; intraoperative thoracoscopic direct-vision transthoracic paravertebral block) or Group B (106 patients; preoperative ultrasound-guided thoracic paravertebral block). Perioperative data, postoperative pain scores, opioid rescue analgesic use, and postoperative complications were analyzed.
