Transforaminal Epiduroscopic Laser Ablation for Removal of a Postlaminectomy Synovial Cyst: A Case Report.

ABSTRACT: Background: Synovial cysts rarely occur after a laminectomy and are difficult to detect if there are no symptoms; however, they can cause lower back pain or symptoms of radiculopathy. Various methods are used to treat synovial cysts. Here, we will introduce the first case with treatment using the transforaminal epiduroscopic laser annuloplasty (TELA) system. Case report: A 64-year-old female patient visited the pain clinic with lower back pain and pain radiating from the left lower extremity. An MRI T2 image showed a synovial cyst of facet joint origin at the L4-L5 level; the patient had undergone a laminectomy 10 years ago at the same spinal level. The patient rated the pain an 8 on the numerical rating scale (NRS), and pain was reduced after epidural steroid injection, but symptoms recurred a month later. The cyst ablation was performed using the TELA system with a 1414 nm neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser, and after the procedure, pain decreased to 4 points immediately and was reduced to 2 points on the NRS after 1 week. Six months after the procedure, the pain level was measured on NRS 2 and cyst was not recurred in the additional MRI. Conclusion: We introduced the TELA system as a noninvasive therapy for treating synovial cysts. Ablation of cystic necks using a 1414 nm Nd:YAG laser could be a method to prevent cyst recurrence, but long-term follow-up and large scale control studies will be needed to verify the effectiveness of this method.

Project description:BackgroundSynovial cysts are benign fluid-filled sacs commonly found in the degenerative lumbar spine. Few studies have reported the detailed epidemiology and standardized therapy for this disease. Conservative treatment is recommended if synovial cysts are asymptomatic or show mild clinical symptoms. If percutaneous facet joint steroid injections are ineffective or neurologic symptoms are aggravated, the open decompression with additional fusion is the reasonable surgical strategy to remove the pain generator. Furthermore, the synovial cysts that occur at the cervicothoracic spine are infrequently, especially accompanied by hemorrhagic radiographic evidence. Therefore, we describe the efficacy and safety of the full-endoscopy surgical procedure assisted by intraoperative O-arm navigation guidance to manage C7/T1 spinal synovial cysts.Case descriptionWe describe a 71-year-old male patient diagnosed with cervicothoracic hemorrhagic synovial cysts. The pathologic site is located at the posterior side of the C7 vertebral body to the medial side of the C7-T1 left facet joint. Herein is described a step-by-step protocol for the full-endoscopic procedure via the posterior approach to remove the lesions under intraoperative O-arm navigation guidance.OutcomeThe patient was successfully treated via full-endoscopic removal of the synovial cysts guided by intraoperative O-arm navigation. Intraoperative bleeding of 30 mL occurred, and the operative time was 150 minutes. The patient's sensory strength improved, and no opioid medicine was required with no complications postoperatively. One-year follow-up magnetic resonance imaging (MRI) and computed tomography (CT) scans showed no synovial cyst recurrence.ConclusionsFull-endoscopy assisted with intraoperative O-arm navigation guidance improves precision and safety in treating patients with synovial cysts of the cervicothoracic spine. The O-arm navigation system improves the efficiency and safety of intraoperative positioning at the cervicothoracic lesion and reduces radiation exposure to the surgeons. Meanwhile, this technique preserves the range of cervicothoracic motion and facilitates the patient return to normal life.
