Neuroradiological and neurosurgical management of arteriovenous malformations of the foramen magnum
Raimund Firsching
Universitaetsklinik Fuer Neurochirurgie, Germany
Introduction: Vascular malformations within the foramen magnum and upper cervical canal are rare. Diagnosis is cumbersome and
neurosurgical treatment is hazardous. We report on 6 cases.
Methods: Age ranged from 37 to 77 years, three male and two female patients. Diagnosis at the time of referral included normal
pressure hydrocephalus (one case), subarachnoid haemorrhage (two cases) and spinal stenosis (two cases). Imaging techniques
included magnetic resonance (MR) imaging, MR angiography and highly selective segmental cervical angiography with micro
catheters. Surgery was performed with electroneurophysiological monitoring.
Results: Angiography revealed three arteriovenous fistulae within the foramen magnum, a giant vertebral artery aneurysm within
the foramen magnum and two patients with an intradural arteriovenous malformation at the C2 level. The fistulae and the aneurysm
were occluded using microclips. The edema of the cervical myelon of the patients with the fistulae resolved with marked recovery
of gait. The hydrocephalus of the patient with the giant vertebral aneurysm also resolved with good recovery. The arteriovenous
malformations at the C2 level were coagulated. One of these patients subsequently needed a ventriculoperitoneal shunt. The other
suffered some transient weakness of the ipsilateral arm.
Conclusion: In all patients suspicion of a vascular malformation was raised after an initially misleading diagnosis. The decisive hint
came from scrupulous evaluation of MR imaging data but diagnosis was only confirmed with selective arteriography. For proper
identification of the malformation and planning of the surgical procedure a highly selective segmental spinal arteriography appears
mandatory.
