Treatment of unruptured intracranial aneurysms using internally expanding coils.
The International Subarachnoid Aneurysm Trial (ISAT) showed that patients with intracranial aneurysms treated with coil embolization have better clinical outcomes than those undergoing neurosurgical clipping. However some patients treated endovascularly have recurrence of aneurysms. Low packing density is often cited as a reason for recurrence. Coiling with hydrogel covered coils significantly improves the packing density. We report our initial experience in using a newly introduced design of hydrogel coils. ⋯ The softness of the hydrogel allowed us to deploy coated coils with good packing density. A slight expansion of these coils at the neck can be expected to reduce any neck remnant and potentially inhibit recurrence.
