F8 Symptom outcome after craniovertebral decompression for Chiari type 1 malformation without syringomyelia
Pepper J, Elhabel A, Tsermoulas G, Flint G.
Specific symptom outcome after craniovertebral decompression is not well defined in patients with Chiari I malformation. In this study we performed a retrospective review of all patients diagnosed with Chiari I malformation without syringomyelia, who underwent craniovertebral decompression in our unit, and assessed the symptoms that improved after surgery. In total, 133 patients were identified with a minimum 2 year follow up. The most common pre-operative symptoms were pressure dissociation headaches (78%), visual disturbances (34%), dizziness/balance disturbances (24%) and blackouts (17%). The symptoms most likely to respond to surgery included headache (72% response, p<0.0001), blackouts (response 87%, P=0.0018) and visual symptoms (58% response, p=0.049).
