Isolated posterior spinal artery aneurysms are rare vascular lesions. We describe the case of a 43-year-old man presenting with spinal subarachnoid hemorrhage after a minor trauma who was found to have a dissecting aneurysm of a posterior spinal artery originating from the right T4 level. Endovascular treatment was not contemplated because of the small size of the feeding artery, whereas surgical resection was deemed more appropriate because of the posterolateral perimedullary location that was well appreciated on CT angiography. After surgical resection of the aneurysm the patient had a complete neurological recovery. In comparison to anterior spinal artery aneurysms whose pathogenesis is diverse, posterior spinal aneurysms are most often secondary to a dissection and represent false or spurious aneurysms. Although the definite diagnosis still requires spinal angiography, MRI and CT may better delineate the relationship of the aneurysm to the spinal cord in order to determine the best treatment method. Prompt treatment is recommended as they have high rebleeding and mortality rates.

Dissecting Aneurysms

We report 17 patients with dissecting aneurysm of the vertebral artery (VA) who were treated by direct surgery (n=8) or interventional surgery (n=9). Eight patients presented with subarachnoid hemorrhage (SAH) and nine with ischemia. Ten patients were treated by trapping of the aneurysm that was occlusion of the VA on both sides of aneurysm (direct surgery, n=2; interventional surgery, n=8). The other seven patients were treated by ligation of the VA proximal to the aneurysm (direct surgery, n=6; interventional surgery, n=1). Two patients underwent transposition of the posterior inferior cerebellar artery (PICA). In 15 patients, there were no major complications. Two patients who had been treated by proximal occlusion of the VA developed rebleeding and ischemia due to persistent retrograde filling of the dissecting site. We suggest that angiographic evidence of retrograde filling of the dissecting site should have been considered as an indication for trapping. Trapping of VA dissecting aneurysms is easier and safer by interventional surgery than by direct surgery.
