Abstract: Objective To evaluate the curative effect and safety of lumbar artery embolization in treating massive hemorrhage caused by percutaneous transforaminal endoscopic discectomy (PTED).Methods From January 2013 to December 2016,lumbar artery angiography was performed in 4 patients with massive hemorrhage caused by PTED.Based on the angiographic findings,lumbar artery embolization therapy with embolic microspheres and spring coils was carried out.Results Lumbar artery angiography revealed that extravasation of contrast agent was detected in 3 patients and pseudoaneurysm in one patient.The bleeding completely stopped immediately after lumbar artery embolization in all 4 patients.The patients were followed up for 1-3 months,and no re-bleeding or serious complications occurred.Conclusion It is very difficult to make medical and surgical management for massive hemorrhage caused by PTED.Lumbar artery embolization is safe,effective and minimally-invasive for the treatment of massive hemorrhage caused by PTED.This therapy is worthy of clinical use.
