Abstract
PURPOSE To investigate the effect of endovascular embolization of posterior communicating artery (Pcom) aneurysms on concomitant oculomotor nerve palsy (OMNP) and factors affecting the effect of treatment. MATERIALS AND METHODS Patients with the Pcom aneurysms concomitant with OMNP were retrospectively enrolled for endovascular treatment of the aneurysms. All patients had the endovascular management. The clinical effect, degree of OMNP, size of the aneurysm, type of treatment, subarachnoid hemorrhage (SAH), and time from onset to treatment were analyzed on the resolution of OMNP. RESULTS Ninety-six patients with 99 Pcom aneurysms were enrolled and treated endovascularly, with the success rate of 100%. Immediately after endovascular treatment, 75 aneurysms (75.75%) got complete occlusion, and 24 (24.24%) nearly complete occlusion. Followed up for 3-18 (mean 8.52±0.56) months, complete resolution of the OMNP was achieved in 63 patients (65.63%), partial resolution in 21 (21.88%), and non-recovery in the other 12 (12.50%). The degree of OMNP at onset, SAH, and time from onset to treatment were significantly (P<0.05) correlated with the resolution of OMNP. Univariate analysis revealed that younger age of the patient, degree of OMNP at onset, presence of subarachnoid hemorrhage, and time from disease onset to treatment were significantly (P<0.05) associated with the recovery of OMNP. Multivariate analysis revealed that the younger age, degree of OMNP at onset, and time from disease onset to treatment were significantly (P<0.05) associated with the recovery of OMNP. CONCLUSION Endovascular embolization of Pcom aneurysms concomitant with OMNP can effectively improve the OMNP symptoms, especially for patients with moderate and a shorter history of OMNP. Younger age, degree of oculomotor nerve palsy at onset, and time from onset to treatment may significantly affect recovery of oculomotor nerve palsy.

Abstract
Flow diverter (FD) stenting is expected to improve cranial nerve symptoms caused by aneurysms via the theoretical reduction of the mass effect by promoting spontaneous thrombosis through the flow diversion effect. However, the factors involved in symptom improvement after treatment remain unclear. This study was performed to identify factors for symptom improvement after FD stenting and the symptom improvement rate of each impaired cranial nerve. We retrospectively evaluated 33 patients who underwent FD stenting for symptomatic internal carotid artery aneurysms at our institution from January 2016 to June 2021. Twenty-three (69.7%) patients had resolved or improved symptoms after 1 year of treatment. The optic nerve was affected in 12 patients; the oculomotor nerve, in 16; the trigeminal nerve, in 2; and the abducens nerve, in 13. There was no statistically significant difference in the symptom improvement rate of each impaired cranial nerve. The patients were classified into the improved and nonimproved groups based on their symptoms after 1 year of treatment, and the factors related to the symptoms were analyzed. The time from onset to treatment was significantly shorter in the improved group than in the nonimproved group (197.1 and 800 days, respectively; p = 0.023). There were no significant differences in age, aneurysm diameter, adjunctive coil embolization, partial thrombosis, change in mass diameter on magnetic resonance imaging, or aneurysm occlusion rate on angiography between the two groups. These results suggest that early treatment after the onset of aneurysm-induced cranial neuropathies increases the likelihood of symptom improvement.

Abstract
Hemifacial spasm due to fusiform aneurysm of the vertebral artery is extremely rare. The lateral spread response (LSR) is routinely used to monitor hemifacial spasms during microvascular decompression to predict the degree of postoperative remission of hemifacial spasm. We report a case of hemifacial spasm caused by an unruptured fusiform vertebral aneurysm treated with intravascular intervention and monitoring of LSR. A 59-year-old man was admitted to the hospital with a left facial spasm that gradually worsened for 1 year. Preoperative cerebrovascular angiography indicated fusiform aneurysms in the intracranial segment of the left vertebral artery close to the left facial nerve. The patient underwent parent artery occlusion and aneurysm embolization, and LSR was monitored intraoperatively. After intraoperative aneurysm embolization, LSR disappeared immediately. The postoperative review of cerebrovascular angiography indicated that the parent artery and aneurysm were embolized successfully, and the patient's left facial spasm was relieved after surgery. Hemifacial spasm caused by the vertebral artery fusiform aneurysm can be safely and effectively treated by parent artery occlusion and aneurysm embolization. Meanwhile, intraoperative LSR monitoring can be used to predict postoperative efficacy.

Oculomotor nerve palsy due to posterior communicating artery aneurysm: Clipping vs coiling. Neurochirurgie 2021; 68:86-93. [PMID: 33845117 DOI: 10.1016/j.neuchi.2021.03.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 03/07/2021] [Accepted: 03/21/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Posterior communicating artery aneurysms (PCoAA) usually present with brain hemorrhage, but they might present with oculomotor nerve palsy (ONP) in about one out of five patients. Treatment options include endovascular coiling and surgical clipping. The present analysis aims to compare the two treatment options for ONP due to PCoAA in terms of complete recovery and related parameters. METHODS A comprehensive literature search was performed for studies published between 2000 and 2019 on ONP due to PCoAA. The included studies were divided into two categories-surgical clipping (group A) and endovascular coiling (group B). The collected data were statistically processed with SPSS version 25. RESULTS There was a significant difference between the two treatment groups regarding complete recovery of ONP (P<0.001), suggesting superiority of the surgical clipping. The correlation analysis showed no correlations for group A. Group B had negative and positive correlations, showing that endovascular coiling results in higher rates of complete ONP recovery for elderly patients. CONCLUSION Surgical clipping is superior to endovascular coiling in terms of complete recovery among patients with ONP due to PCoAAs. Endovascular coiling seems to benefit older patients. While no recommendations exist for the treatment of ONP due to intracranial aneurysms, an increasing number of studies imply the superiority of operative clipping.

Abstract
BACKGROUND Hemifacial spasm (HFS) caused by vertebral artery (VA) aneurysms is rare. Several cases of HFS caused by VA aneurysms treated by endovascular parent artery occlusion (PAO) have been reported. Recently, we treated a rare case of HFS caused by a saccular VA aneurysm at the bifurcation of the posterior inferior cerebellar artery (PICA), which was successfully treated by endovascular coil embolization, preserving the parent artery, and PICA. We discuss endovascular treatment for HFS induced by VA aneurysms with a literature review. CASE DESCRIPTION A 59-year-old man presented with the left HFS persisting for 2 months. Magnetic resonance imaging revealed a left saccular VA-PICA aneurysm and demonstrated that a left facial nerve was compressed by the aneurysm at the root exit zone. Angiography revealed that the PICA was branching from the aneurysm neck. Endovascular coil embolization was performed using the balloon remodeling technique to preserve the left VA and PICA. HFS disappeared after treatment. CONCLUSION Although microvascular decompression was commonly accepted for the standard treatment of HFS, coil embolization of aneurysms without PAO may be an effective treatment for HFS caused by VA aneurysms.

Abstract
BACKGROUND Oculomotor nerve palsy (ONP) is a common clinical presentation of posterior communicating artery (PcomA) aneurysms. It remains unclear if patients have a better rate of recovery after surgical clipping or endovascular coiling. OBJECTIVES The main objectives of this study were to assess the overall rate of ONP recovery after endovascular coiling of PcomA aneurysms, as well as to determine the associated predictive factors of oculomotor nerve recovery. METHOD We retrospectively evaluated the demographic, clinical, and radiological characteristics and the outcome of consecutive patients presenting with PcomA aneurysms treated by endovascular coiling from January 2012 to November 2016 with at least 1 year clinical and radiological follow-up. Statistical analysis was applied to determine the association between ONP recovery and the demographic, clinical and radiological variables. RESULTS A total of 91 patients with PcomA aneurysms were treated endovascularly. Thirty-four patients (22 women and 12 men) with ONP related to PcomA aneurysms were included. The mean age of the patients was 49.8 years. Subarachnoid haemorrhage was present in 27 patients. The mean aneurysm size was 6.7 mm. The overall rate of recovery was 88.2%. Complete nerve recovery was seen in 16 (47%) patients and partial recovery was observed in 14 (41.2%) patients, whilst 4 (11.8%) patients remained unchanged after treatment. The non-posterolateral direction of the aneurysm showed a tendency towards better recovery compared to the posterolateral projection (p = 0.06). CONCLUSION Endovascular coiling of PcomA aneurysms in patients with ONP resulted in a cure or improvement of oculomotor nerve dysfunction in the majority of patients.

Abstract
BACKGROUND Intracranial saccular aneurysms are acquired lesions that often present with neuro-ophthalmologic symptoms and signs. Recent advances in neurosurgical techniques, endovascular treatments, and neurocritical care have improved the optimal management of symptomatic unruptured aneurysms, but whether the chosen treatment has an impact on neuro-ophthalmologic outcomes remains debated. EVIDENCE ACQUISITION A review of the literature focused on neuro-ophthalmic manifestations and treatment of intracranial aneurysms with specific relevance to neuro-ophthalmologic outcomes was conducted using Ovid MEDLINE and EMBASE databases. Cavernous sinus aneurysms were not included in this review. RESULTS Surgical clipping vs endovascular coiling for aneurysms causing third nerve palsies was compared in 13 retrospective studies representing 447 patients. Complete recovery was achieved in 78% of surgical patients compared with 44% of patients treated with endovascular coiling. However, the complication rate, hospital costs, and days spent in intensive care were reported as higher in surgically treated patients. Retrospective reviews of surgical clipping and endovascular coiling for all ocular motor nerve palsies (third, fourth, or sixth cranial nerves) revealed similar results of complete resolution in 76% and 49%, respectively. Improvement in visual deficits related to aneurysmal compression of the anterior visual pathways was also better among patients treated with clipping than with coiling. The time to treatment from onset of visual symptoms was a predictive factor of visual recovery in several studies. Few reports have specifically assessed the improvement of visual deficits after treatment with flow diverters. CONCLUSIONS Decisions regarding the choice of therapy for intracranial aneurysms causing neuro-ophthalmologic signs ideally should be made at high-volume centers with access to both surgical and endovascular treatments. The status of the patient, location of the aneurysm, and experience of the treating physicians are important factors to consider. Although a higher rate of visual recovery was reported with neurosurgical clipping, this must be weighed against the potentially longer intensive care stays and increased early morbidity.

Abstract
Neurologists should be aware of specific urgent and emergent neuro-ophthalmic conditions, including giant cell arteritis, arterial dissection, intracranial aneurysm, pituitary apoplexy, and invasive sino-orbital fungal infection (eg, mucormycosis). Early recognition and treatment can greatly impact patient morbidity and mortality, including the preservation of vision and life. Neurologists should be cognizant of the key and differentiating clinical and radiographic features for these presentations.

Abstract
Functional recovery after oculomotor nerve injury is very poor. Electrical stimulation has been shown to promote regeneration of injured nerves. We hypothesized that electrical stimulation would improve the functional recovery of injured oculomotor nerves. Oculomotor nerve injury models were created by crushing the right oculomotor nerves of adult dogs. Stimulating electrodes were positioned in both proximal and distal locations of the lesion, and non-continuous rectangular, biphasic current pulses (0.7 V, 5 Hz) were administered 1 hour daily for 2 consecutive weeks. Analysis of the results showed that electrophysiological and morphological recovery of the injured oculomotor nerve was enhanced, indicating that electrical stimulation improved neural regeneration. Thus, this therapy has the potential to promote the recovery of oculomotor nerve dysfunction.

Abstract
Neuro-ophthalmological emergencies constitute vision or life-threatening conditions if diagnosis and treatment are not promptly undertaken. Even with immediate therapy, these clinical entities carry a high rate of morbidity. They may present with diplopia, visual loss, and/or anisocoria. Arteritic anterior ischemic optic neuropathy is an ominous condition, which can cause permanent and severe vision loss, stroke, or aortic dissection, requiring immediate steroid therapy. Pituitary apoplexy may go unnoticed if only computed axial tomography is performed. Diseases affecting the cavernous sinus and orbital apex region, such as cavernous sinus thrombosis or mucormycosis, can give rise to simultaneous vision loss and diplopia and, if not treated, may extend to the brain parenchyma causing permanent neurological sequela. An isolated third nerve palsy may be the harbinger of a cerebral aneurysm, carrying a significant risk of mortality. Horner syndrome can be the initial presentation of a carotid dissection, an important cause of stroke in the young adult. The neurohospitalist should be familiar with the workup and management of neuro-ophthalmological emergencies.

Abstract
BACKGROUND:
Previous studies have attempted to determine the best treatment for oculomotor nerve palsy (ONP) secondary to posterior communicating artery (PCoA) aneurysms, but have been limited by small sample sizes and limited treatment.
OBJECTIVE:
To analyze the treatment of ONP secondary to PCoA with both coiling and clipping in ruptured and unruptured aneurysms.
METHODS:
Data from 2 large academic centers was retrospectively collected over 22 years, yielding a total of 93 patients with ONP secondary to PCoA aneurysms. These patients were combined with 321 patients from the literature review for large data analyses. Onset symptoms, recovery, and time to resolution were evaluated with respect to treatment and aneurysm rupture status.
RESULTS:
For all patients presenting with ONP (n = 414) 56.6% of those treated with microsurgical clipping made a full recovery vs 41.5% of those treated with endovascular coil embolization (P = .02). Of patients with a complete ONP (n = 229), full recovery occurred in 47.3% of those treated with clipping but in only 20% of those undergoing coiling (P = .01). For patients presenting with ruptured aneurysms (n = 130), full recovery occurred in 70.9% compared with 49.3% coiled patients (P = .01). Additionally, although patients with full ONP recovery had a median time to treatment of 4 days, those without full ONP recovery had a median time to treatment of 7 days (P = .01).
CONCLUSION:
Patients with ONP secondary to PCoA aneurysms treated with clipping showed higher rates of full ONP resolution than patients treated with coil embolization. Larger prospective studies are needed to determine the true potential of recovery associated with each treatment.

Oculomotor nerve palsy induced by internal carotid artery aneurysm: prognostic factors for recovery. Acta Neurochir (Wien) 2015; 157:1103-11. [PMID: 25956395 DOI: 10.1007/s00701-015-2440-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 04/28/2015] [Indexed: 12/27/2022]
Abstract
BACKGROUND Aneurysms at the posterior face of the internal carotid artery can lead to oculomotor nerve palsy (ONP) with an uncertain prognosis of recovery post-treatment. The aim of this study was to define the prognostic factors for ONP recovery, with particular interest in treatment modality (surgery or endovascular techniques). METHOD A literature review was performed to select the most pertinent prognostic factors. A retrospective study was then performed to determine whether these factors had significantly modified the prognosis of ONP recovery in our series of patients. RESULTS In the literature, factors linked to poorer outcome were age, vascular risk factors, initial ONP severity and delay before treatment; better recovery was associated with surgical treatment. Between 2000 and 2013, 23 consecutive patients were treated in our department for ONP-inducing aneurysms: 14 by endovascular embolization and 9 by surgical clipping and aneurysm puncture. Mean follow-up was 48.8 months. After treatment, overall recovery occurred in 87% of cases, always within 6 months. Apart from treatment modality, no selected prognostic factor significantly modified the quality or timing of ONP recovery. In the endovascular group, four patients recovered completely, seven partially and three did not recover. In the surgical group, seven patients recovered completely and two partially. Surgery was significantly associated with a more complete and earlier ONP recovery (p < 0.05). CONCLUSIONS Surgery was associated with a more complete and earlier ONP recovery as compared to endovascular treatment, confirming the results of previous studies. However, conclusions must be confirmed by a prospective randomized study.

Abstract
Giant intracranial aneurysms are rare disorders that represent only 5% of all intracranial aneurysms; they have a wide variety of presentations including rupture, embolic effects, and mass effect symptoms that can mislead the diagnosis to tumors rather than aneurysms. Their treatment is difficult and carries higher morbidity and mortality than usual aneurysms due to their complex nature. This study involved retrospective analysis of data of 28 patients, managed between 2006 and 2012, suffering from giant internal carotid artery (ICA) aneurysms with various presenting symptoms, none of which was hemorrhage. They were all evaluated by BOT prior to any intervention; they were subjected to various treatment strategies including selective coiling, parent artery occlusion with or without bypass, aneurysm trapping with or without bypass, and patients were followed for a period ranging from 6 months to 5 years. Out of 26 patients with giant aneurysms with mass effects, 16 patients showed full recovery (61.5 %), 5 showed partial improvement (19.2 %), and 5 showed no change in mass effect symptoms (19.2 %). One patient died (3.5 %). Symptoms such as TIA or epistaxis showed complete recovery. This study shows that a well-designed protocol aiming at parent artery sacrifice will yield good to excellent results in managing ICA giant aneurysms, and it also shows that parent artery sacrifice is superior to other forms of treatment of these lesions regarding recurrence rates, morbidity, and mortality.

Abstract
PURPOSE The recovery time of traumatic carotid-cavernous fistula-induced oculomotor nerve paresis (ONP) after endovascular embolization with detachable balloons has not yet been adequately evaluated. This study was performed to make a deep analysis of the factors, which affect the prognosis of ONP after endovascular treatment of traumatic carotid-cavernous fistula (TCCF). MATERIALS AND METHODS We retrospectively evaluated the clinical characteristics and the outcome of oculomotor nerve function in a series of 98 consecutive patients with ONP due to traumatic carotid-cavernous fistula which were endovascular treated with detachable balloons. Univariate analysis was applied to test the association between the time of ONP recovery and clinical variables. RESULTS Ninety-eight consecutive patients (62 males, 36 females, mean age 34.2±12.7years) having presented with ONP underwent endovascular treatment with detachable balloons were enrolled in this study. ONP was complete in 22 (22.4%) patients and partial in 76 (77.6%) patients. Ninety (91.8%) patients were successfully occluded by single-session endovascular embolization. Retreatments by transarterial routes had to be performed in 8 (8.2%) patients because of recurrent fistula having occurred within 4weeks after embolization. ONP was recovered completely in all the patients, among who 4 (4.1%) were treated with occlusion of internal carotid artery. Factors showing significant association with the recovery time of ONP were the location of the fistula (P=0.007), the degree of preoperative ONP (P=0.003), the number of detachable balloon used (P=0.000) and the length of ONP before endovascular treatment (P=0.000). CONCLUSION Endovascular treatment of traumatic carotid-cavernous fistula-induced ONP with detachable balloons is a safe and effective method. The length of ONP before endovascular treatment, the location of the fistula, the degree of preoperative ONP, the number of detachable balloons used were the statistically significant predictors of the length of ONP complete recovery.
