Percutaneous drainage of a postoperative intraspinal hematoma using a Tuohy needle.
A 78-year-old man developed a large subdural hematoma extending from T12 to L3 levels following L3 laminectomy and L3-5 posterior spinal fusion. He had associated neurological signs and symptoms. MR imaging showed typical signal characteristics of a subacute intraspinal subdural hematoma. Percutaneous drainage was successfully performed under CT guidance by inserting a Tuohy needle through the L3 laminectomy defect. The catheter packaged with the Tuohy needle was inserted cranially into the hematoma and 30 ml of blood was aspirated. Follow-up MR imaging confirmed resolution of the hematoma and the patient made a rapid recovery.
