Failed back surgery syndrome was recently renamed, as chronic pain after spinal surgery (CPSS) by international classification of disease-11. CPSS is a challenging clinical condition. It has a variety of causes associated with preoperative, intraoperative and postoperative periods. Also, psychosocial factors should be considered. Diagnostic tools must be used differently, for each patient. Imaging and interventional nerve block for diagnosis, should be used properly. Strategy of management requires a multidisciplinary approach. The effect of conservative management (medication, interventional management) and invasive procedure (spinal cord stimulator, intrathecal drug delivery system) has been studied by many researchers. However, an evidence-based guide on management of CPSS, remains necessary, and further research is needed. This review focuses on understanding and clinical approaches for CPSS.

Seizure is the second most common neurologic complication after liver transplantation and may be caused by metabolic abnormalities, electrolyte imbalance, infection, and immunosuppressant toxicity. A 61-year-old male patient underwent liver transplantation due to hepatitis B virus-related liver cirrhosis with portal systemic encephalopathy. The immediate postoperative course of the patient was uncomplicated. However, on postoperative day (POD) 6, weakness developed in both lower extremities. No abnormal findings were detected on a brain computed tomography (CT) scan on POD 8, but a generalized tonic clonic seizure developed which was difficult to control even with multiple antiepileptic drugs. A follow-up brain CT scan on POD 15 showed a 2.7 cm sized acute intracranial hemorrhage (ICH) in the left parietal lobe. The patient’s mental status improved after 2 months and he was able to communicate through eye blinking or head shaking. Our case reports an acute ICH that manifested into a refractory seizure in a patient who underwent a liver transplant.
