Efficacy of dual stent-assisted coil embolization in ruptured vertebral artery dissecting aneurysms / 中华神经医学杂志

ABSTRACT

Objective:To evaluate the safety and efficacy of dual stent-assisted coil embolization in intracranial ruptured vertebral artery dissecting aneurysms (VADAs).Methods:Seventeen patients with intracranial ruptured VADAs (17 aneurysms), treated with dual stent-assisted coil embolization in our hospital from September 2015 to March 2020, were recruited. DSA was performed immediately after surgery to evaluate the embolization degrees of VADAs. At the end of follow-up, modified Rankin scale (mRS) was used to evaluate the prognoses of these patients, and DSA was used to determine the healing status of aneurysms.Results:The postoperative immediate DSA showed that total occlusion was achieved in 6 patients (35.3%), subtotal occlusion in 8 (47.1%) and partial occlusion in 3 (17.6%). Two patients died during the perioperative period and 2 patients presented symptoms of cranial nerve palsy after surgery. Fifteen patients were followed up for 5-24 months, 14 were with good prognosis, and one was with poor prognosis. Eleven patients underwent DSA follow-up, which showed that 8 aneurysms healed completely, 2 aneurysms were stable, and 1 aneurysm recurred.Conclusion:Dual stent-assisted coil embolization may be an effective and safe treatment method for intracranial ruptured VADAs.
