 Ruptured vertebral artery dissecting aneurysms(VADA)carry a poor prognosis owing to the high rates of rebleeding, stroke, and mortality without appropriate treatment. Various endovascular techniques are employed to treat these aneurysms. Deconstructive techniques, involving internal trapping with coils, often achieve complete angiographic occlusion at higher rates; however, they carry a risk of medullary infarction. Reconstructive techniques using neck-bridge stents preserve the parent vessel and reduce perioperative morbidity. Nevertheless, these techniques are associated with a higher rate of aneurysmal rebleeding or recurrence. Optimal treatment modalities should be chosen based on the anatomical characteristics of the aneurysm and the trade-off between risks and benefits.
