In view of the rarity of neurological complications following epidural analgesia alone, careful consideration should be paid to other medical or surgical causes (other than post-operative epidural injection as such) to account for post-operative acute myelopathy. insults in the perioperative setting of complicated abdominal surgery. Epidural analgesia is usually a common and relatively safe process to alleviate pain and to speed up recovery after abdominal surgery. The incidence of acute myelopathy due to central neural blockade after epidural analgesia is extremely rare. In view of the rarity of neurological complications following epidural analgesia alone, careful consideration should be paid to other medical or surgical causes (other than post-operative epidural injection as such) to account for post-operative acute myelopathy. In addition, it is important to recognise the indicators of myelopathy rather than attributing the findings to delayed wearing-off of the analgesic effect. We statement the unusual SRT 1720 Hydrochloride case of a young adult who developed spinal cord infarction in the setting of surgical evacuation of intra-abdominal (liver) haematoma and thoracic epidural analgaesia. == Case Statement == A 28-year-old woman, admitted to a hospital in Oman, tested positive for hepatitis C viral (genotype 4) contamination by polymerase chain reaction assay. She experienced no vascular risk factors such as hypertension, diabetes mellitus, atrial fibrillation, and hyperlipidemia. To establish the extent of liver pathology and to plan further management she underwent an elective liver biopsy in another institution. Two days after the process, she developed right upper abdominal pain and vomiting. The haemoglobin (Hb) decreased from 12 to 10 gm/l. An abdominal sonogram showed a hepatic subcapsular haematoma and she received 3 models of packed reddish cell transfusion. Despite the blood transfusion, the Hb remained low. Prolonged intra-abdominal bleeding was suspected and an urgent abdominal computed tomography (CT) scan confirmed considerable haemorrhage in the peritoneal cavity and the pelvis. The following day (third day after the biopsy), she was transferred to our institution for further management including emergency laparotomy. At pre-operative assessment in our centre, the blood pressure was 130/82 mmHg, and the heart rate ranged from 130 to 140 beats per minute. Hb remained stable at 10 gm/l and the coagulation profile was within normal limits. The neurological examination was unremarkable. Intra-operatively she remained haemodynamically stable and there was no episode of hypotension. To arrest the continual oozing of blood from the liver surface, surgical packing of the liver was performed. At the end of the procedure, an epidural catheter was inserted at the thoracic (T)1112 intervertebral space as per the standard technique of postoperative analgesia. A bolus of 10ml of 0.125% bupivacaine along with fentanyl 20 mcg was injected initially, followed by an infusion at 6ml/hr. She was extubated successfully in the rigorous care unit an hour later and the rate of infusion was increased SRT 1720 Hydrochloride to 10ml/hr as she continued to experience pain. She did not demonstrate hypotension during the process. Eight hours after the initiation of epidural analgesia, she complained of an inability to move her lower limbs and the epidural infusion was withheld. Neurologically, she exhibited flaccid paraplegia (power of 0/5 in legs), sensory level at T8 dermatome (below which the main modalities of sensation were lost) and areflexia in the lower limbs along with extensor plantar response and bowel and bladder disturbances. Emergent magnetic resonance imaging (MRI) of the spine revealed diffuse hyperintensity of the distal spinal cord, but sparing the terminal end and the conus [Physique 1a]. Around the transverse T2 weighted image, it was observed SRT 1720 Hydrochloride that the transmission abnormality corresponded to the central grey matter around the left side, while sparing the peripheral white matter [Physique 1b]. The ischaemic nature of the lesion was confirmed on diffusion weighted MR images. There was no evidence of epidural mass/compression, fluid collection, bone changes or acute traumatic injury. Serial clinical examination exhibited prolonged weakness and sensory indicators indicating that the sensory changes were not due to delayed wearing-off of the analgesic effect. == Physique 1a. == Sagittal T2 weighted magnetic resonance imaging Rab21 (initial scan) demonstrating diffuse bright transmission (horizontal arrow) in the distal a part of spinal cord.

A lumbar tap showed obvious cerebrospinal fluid (CSF). CSF findings included glucose of 5.3 mmol/l (serum glucose 6 mmol/l), protein SRT 1720 Hydrochloride of 0.42 g/l, IgG.
