Angiographic outcome of intracranial aneurysms with neck remnant following coil embolization

摘要: Background The degree of aneurysm occlusion following coil embolization has an impact on recanalization. Objective To explain the natural history intracranial aneurysms with neck remnant, Raymond–Roy Occlusion Classification (RROC) class II. Methods A single-center, retrospective study 198 patients 209 treated that were initially either RROC I or angiographic outcomes at short- and long-term follow-up compared as well complication/re-treatment rates. Atypical those had been previously excluded. Results Ninety-nine 110 II aneurysms. There was no difference in recanalization rate between groups (class 3.3% vs 8.5%, p=0.478) short-term (8.2 months) subsequent follow-ups (21.7 52.1 months). also re-treatment rates p=0.196) complication 9.1% 4.6%, p=0.12). ruptures after treatment group. Conclusions outcome remnant is similar to completely occluded most remain stable few recanalize. This understanding could potentially help interventional neurosurgeon avoid complications such herniation, vessel compromise, stroke selected cases. Further investigation a larger patient population warranted.
