Long-term follow-up study of 35 cases after endovascular treatment for vertebrobasilar dissecting aneurysms

For patients with ruptured VBDAs, the complication rate associated with endovascular treatment is acceptable. CE + PT is better than stent coiling in preventing aneurysmal rerupture, but is associated with a high incidence of ischemic stroke. For unruptured VBDAs, endovascular treatment is associated with good clinical outcome without perioperative complications, including rerupture and ischemic stroke. However, the high postoperative recurrent aneurysm risk suggests the necessity of long-term angiographic follow-up monitoring of VBDA patients who undergo endovascular treatments.
