Treatment of a Symptomatic Epidural Gas Cyst Using an Angiographic 5F Catheter in the Epidural Space of the Spinal Cord through the Sacral Hiatus. A Case Report.
An 85-year-old woman arrived at our institution because of left lumbar sciatica of about two years duration unrelieved by conventional oral pain therapy. A computed tomography scan obtained at the second visit showed an epidural gas cyst, with compression and dislocation of the left spinal nerve root L5. The common treatment of an epidural gas cyst is either a direct surgical approach or a CT-guided needle aspiration. We describe an alternative method to mechanical lysis of epidural gas cysts with the use of an 5F angiographic catheter inserted on a 0.035-inch guidewire. This procedure is less invasive than a surgical approach and safer than a CT-guided needle aspiration. Remission of symptoms was maintained at control visits at three and five months.
