Unintended intrapleural insertion of an epidural catheter in thoracic surgery: regional analgesia game over, or is there another way out?

Abstract

In thoracic surgery, optimized pain control is crucial to prevent dysfunction in cardiorespiratory mechanics. Epidural anesthesia (EA) and paravertebral block (PVB) are the most popular techniques for analgesia. Unintended intrapleural insertion of an epidural catheter is a rare complication. Our report presents a case of a patient submitted to pulmonary tumor resection by video-assisted thoracoscopic surgery (VATS). There was difficulty in epidural insertion related to patient's obesity, but after general anesthesia induction, no additional intravenous analgesia was needed after epidural injection. Surgery required conversion to thoracotomy, with intrapleural identification of epidural catheter. At the end of surgery, surgeons reoriented catheter to paravertebral space, with leak absence confirmation after local anesthetic injection through the catheter. In postoperative period, pain control was efficient, with no complications. It was a successful case that shows that when we find unexpected complications, we can look for alternative solutions to give our patient the best treatment.
