Resolution of cranial nerve paresis after endovascular management of cerebral aneurysms

Endovascular Treatment of Posterior Communicating Artery Aneurysms with Oculomotor Nerve Palsy: Clinical Outcomes and Predictors of Nerve Recovery

“…Patient anatomy could account for an occasional ONP occurring with small unruptured PcomA aneurysms. A variety of factors have been found to influence ONP recovery in the literature, including the degree of initial palsy, 4,5,7,8,11,18 treatment timing, 8,11,19 subarachnoid hemorrhage, 6,8,10 patient age, 14 and cardiovascular risk factors. 14 In the present study, a partial ONP at presentation was the only statistically significant predictor of complete ONP recovery with endovascular therapy.…”

“…5 Recently published studies have reported remarkably high rates of complete nerve recovery with endovascular therapy (50%-85%), equaling or even exceeding those observed with surgical clipping. [8][9][10] Results of these studies, however, are limited by the sample size, which precludes any confident conclusion as to the efficacy of endovascular therapy in this setting. We investigated the clinical outcome of ONP with different endovascular embolization techniques in a series of 37 patients treated in our institution.…”

Partially Thrombosed Intracranial Aneurysms Presenting with Mass Effect: Long-Term Clinical and Imaging Follow-Up after Endovascular Treatment

“…Large basilar tip and SCA aneurysms may cause CN III palsy, and PICA aneurysms can cause compression the trigeminal or the facial nerve. [1][2][3] Partially thrombosed aneurysms are difficult to treat. The neurosurgical approach often requires techniques other than conventional clipping, such as thrombectomy with clip reconstruction, and is frequently associated with prolonged ischemia, failed reconstruction, and poor results.…”

Unruptured Large and Giant Carotid Artery Aneurysms Presenting with Cranial Nerve Palsy: Comparison of Clinical Recovery after Selective Aneurysm Coiling and Therapeutic Carotid Artery Occlusion

“…11 The effect on cranial nerve dysfunction of selective occlusion with coils of ICA aneurysms in general and large and giant aneurysms specifically is poorly understood. [12][13][14][15][16][17][18] In this study, we assess the clinical evolution of aneurysm-induced cranial nerve dysfunction after selective coil occlusion in 16 patients with 17 unruptured large and giant ICA aneurysms and compare the results with historical data of patients with similar aneurysms and symptoms treated with ICA occlusion.…”
