title: Transient intradural catheter lysis in a patient with a diffuse and elongated subdural hematoma of the spine due to trauma. Case report.
abstract: The often extended and elongated configuration of a diffuse subdural hematoma of the spine makes it impossible to completely evacuate with common neurosurgical approaches. The authors describe the complete evacuation of a diffuse subdural hematoma of the entire spine due to trauma in a patient who suffered myelopathy and paraplegia in succession, by using transient subdural catheter lysis. After the patient underwent a partial hemilaminectomy at T7-8 and L2-3 using a lateral transmuscular approach, a 15 cm-long intraventricular catheter was inserted at each hemilaminectomy site and connected to an external ventricular drainage system in a procedure lasting 1 hour. Subsequently, 5000 IU of urokinase was applied four times daily for 30 minutes each time over the next 5 days. Two months later, the patient presented with spastic paraparesis Manual Muscle Test Grade 4/5. Magnetic resonance (MR) imaging revealed no catheter-related complications. The authors conclude from this case that transient catheter lysis may be an effective and gentle method to treat diffuse and elongated subdural hematomas of the spine due to trauma. A larger series needs to be analyzed, however, to address the indications and limitations of the technique compared with conventional open surgery. Such evaluation should include serial MR imaging and electrophysiological examination.
