Objective Isolated dissecting spinal aneurysms are rare lesions that pose a therapeutic challenge. We report our experience in the management of four patients with dissecting spinal aneurysms.

Methods After institutional review board approval was obtained, the neurointerventional databases of the two participating institutions were retrospectively reviewed. Aneurysms in the anterior spinal artery, posterior spinal artery, or in a radiculomedullary artery were included in the analysis. Flow-related aneurysms were excluded. Data on clinical presentation, hemorrhage location, aneurysm size, location, angiographic follow-up, re-hemorrhage, and clinical outcome were obtained and analyzed.

Results Four patients with five spinal dissecting aneurysms met the inclusion criteria. There were two women and the mean age was 63 years (range 36–64). All patients presented with hemorrhage. Three radiculomedullary arteries in two different patients had one lesion each; the other two involved the anterior spinal artery and a posterior spinal artery in different patients. All four patients were managed conservatively. Follow-up angiography (5.5 months) demonstrated occlusion of all five aneurysms. There was no re-hemorrhage and all patients had a good outcome at the last follow-up (modified Rankin Scale score 0–2).

Conclusions Conservative management of ruptured spontaneous dissecting spinal aneurysms is a reasonable therapeutic option capable of achieving favorable angiographic and clinical outcomes.
