ABSTRACT
Venous varicose of epidura is considered a rare cause of nerve root and thecal sac compression and impingement that leads to lower limb radiculopathy. The purpose of this study is to draw attention to this problem during operation. It also aims to focus shed a light on using magnetic resonance imaging (MRI) before the operation. This research also attempts to evaluate the outcome of the surgery. Symptoms of epidural varicose with radiculopathy are rare and the diagnosis is often inaccurate by preoperative clinical examination and radiology investigations. Thus, in many cases the diagnosis is made intra- operatively. The case was a 40 years old female who consulted our outpatient clinic complaining from acute radicular pain in the lower back and down of her right lower limb. MRI was done for her and showed paracentral disc herniation. Intra operatively, an abnormal dilatation of epidural vein impingement on L4 nerve root with no foraminal stenosis was seen. We initiated a thermo coagulation of the epidural vein from proximal to distal ends at disc level and used gel foam patch to control bleeding that was removed all at the end of operation. Then, coagulation ablation was performed. The operation resulted in relief of symptoms and neurologic recovery occurred during follow up period. According to our case and previously published case reports, the outcome is good with recovery of neurological signs and symptoms that can be obtained by coagulation ablation of epidural varicose vein.
