The dissecting aneurysms of vertebral artery with various clinical manifestations have been increasingly reported with recent advent of diagnostic tools such as 3-Dimension computed tomography angiogram, magnetic resonance image and conventional angiogram. The authors analyzed the various treatment modalities according to their clinical presentations of vertebral artery dissecting aneurysms.
At the author's institution between March 2001 and February 2004, 28 patients were managed under diagnose of vertebral artery dissection. The medical record and neuroimaging studies of patients were reviewed retrospectively.
Seven patients were presented with subarchnoid hemorrhage and 2 patients with mass effect. The other 12 patients were presented with ischemic stroke and 7 patients with headache or neck pain. 19 patients were treated with endovascular coils or stent. The other 8 patients were treated conservatively. and one patient was treated with operation. We had no endovascular treatment-related complications. Sixteen patients who underwent endovascular treatment survived with good recovery. but one patient died and 2 patients were in poor neurological status. Among patients with mass effect, one patient was treated with operation. and the other one patient with endovascular coils. We obtained optimal treatment results with improvement of myelopathy in both patients.
The choice of the treatment of vertebral artery dissecting aneurysm of patients, clinical characteristics, and relation with posterior inferior cererebellar artery. The endovascular treatment using stent with/without coiling could be the treatment of choice if preservation of the vertebral artery is necessory.
