Surgical Results of Unruptured Intracranial Aneurysms in the Elderly : Single Center Experience in the Past Ten Years

Objective

As medical advances have increased life expectancy, it has become imperative to develop specific treatment strategies for intracranial aneurysms in the elderly. We therefore analyzed the clinical characteristics and outcomes of the treatment of unruptured intracranial aneurysms in patients older than 70 years.

Methods

We retrospectively reviewed the medical records and results of neuroimaging modalities on 54 aneurysms of 48 consecutive patients with unruptured intracranial aneurysms. (mean±SD age, 72.11±1.96 years; range, 70-78 years) who underwent surgical clipping over 10 years (May 1999 to June 2010).

Results

Of the 54 aneurysms, 22 were located in the internal carotid artery, 19 in the middle cerebral artery, 12 in the anterior cerebral artery, and 1 in the superior cerebellar artery. Six patients had multiple aneurysms. Aneurysm size ranged from 3 mm to 17 mm (mean±SD, 6.82±3.07 mm). Fifty of the 54 aneurysms (92.6%) were completely clipped. Three-month outcomes were excellent in 50 (92.6%) aneurysms and good and poor in 2 each (3.7%), with 1 death (2.0%). Procedure-related complications occurred in 7 aneurysms (13.0%), with 2 (3.7%) resulting in permanent neurological deficits, including death. No postoperative subarachnoid hemorrhage occurred during follow-up. The cumulative rates of stroke- or death-free survival at 5 and 10 years were 100% and 78%, respectively.

Conclusion

Surgical clipping of unruptured intracranial aneurysms in elderly group could get it as a favorable outcome in well selected cases.     

Outcome following surgery for ophthalmic segment aneurysms

Ophthalmic segment aneurysms account for about 5% of all intracranial aneurysms. Anatomical complexity of the paraclinoid region makes surgical management of aneurysms arising from the ophthalmic segment challenging. This study was carried out to assess the presenting features, complications and outcomes after surgical treatment of ophthalmic segment aneurysms. The authors retrospectively analysed the clinical records of patients with ophthalmic aneurysms treated at our Institute from January 2001 to September 2008, which constituted about 9% (78/850) of all intracranial aneurysms. Of the 78 ophthalmic segment aneurysms, six patients (8%) had giant aneurysms and 19 (24%) patients had multiple aneurysms. Fifty-six patients underwent microsurgery, with direct clipping in most. The mean age was 42 years (range 12–75 years) and the mean follow-up was 8 months (range, 2–93 months). A good outcome was achieved in 46 (83%) patients (Glasgow Outcome Scale [GOS] score 4–5) and 17% had a poor outcome (GOS score 1–3) at last follow-up. The overall complication rate was 21% (12/56), most of which were transient complications, with 3.5% (2/56) mortality. Direct microsurgical clipping remains our preferred treatment approach, whenever possible, for ophthalmic segment aneurysms. This surgery has an acceptable complication rate and leads to a good outcome in more than 80% of patients with ophthalmic aneurysms. Use of modern microsurgical instrumentation and endovascular adjuncts can further reduce the surgical morbidity associated with these vascular lesions.

Endovascular management of unruptured intracranial aneurysms: does outcome justify treatment?

OBJECTIVE: The appropriate management of unruptured intracranial aneurysms depends on a complete understanding of their natural history and on the risks and efficacy of treatment options. There is little current data on the risks of endovascular therapy for these aneurysms. The aim of this study was to assess outcome of endovascular treatment of unruptured intracranial aneurysms. METHOD: A retrospective analysis was performed on all unruptured aneurysms treated by Guglielmi detachable (GD) coils at this institution from 1994 to 2000. RESULTS: Seventy three unruptured aneurysms were treated in 62 patients. There were 52 female and 10 male patients, with a median age of 55.7 years. Clinical background was: subarachnoid haemorrhage due to rupture of an additional aneurysm (40), headache (4), third nerve palsy (four), familial (four), and incidental (10). There were 14 technical failures with no clinical sequelae. Four procedural complications occurred (5.5%, 95% confidence interval (95% CI) 0.3% to 10.9%). One patient had temporary clinical sequelae (1.4%, 95% CI 0% to 2.7%); 79% of treated aneurysms had stable occlusions at follow up, 10.5% showed improved occlusion grade, 10.5% showed some recurrence, and three patients have required retreatment. Follow up modified Glasgow outcome scores were grade 1, 71%; grade 2, 18%; grade 3, 3%; grade 4, 3%. There were no deaths or haemorrhages during the follow up period. Two patients died as a result of complications from subarachnoid haemorrhage. CONCLUSION: The endovascular treatment of patients with unruptured aneurysms is safe with few clinical or procedural complications. Poor outcomes were only seen in those patients who presented with subarachnoid haemorrhage due to rupture of an aneurysm at another site.     

The Merits of Endovascular Coil Surgery for Patients with Unruptured Intracranial Aneurysms

Objective

The purpose of this study was to report the morbidity, mortality, angiographic results, and merits of elective coiling of unruptured intracranial aneurysms.

Methods

Ninety-six unruptured aneurysms in 92 patients were electively treated with detachable coils. Eighty-one of these aneurysms were located in the anterior circulation, and 15 were located in the posterior circulation. Thirty-six aneurysms were treated in the presence of previously ruptured aneurysms that had already undergone operation. Nine unruptured aneurysms presented with symptoms of mass effect. The remaining 51 aneurysms were incidentally discovered in patients with other cerebral diseases and in individuals undergoing routine health maintenance. Angiographic and clinical outcomes and procedure-related complications were analyzed.

Results

Eight procedure-related untoward events (8.3%) occurred during surgery or within procedure-related hospitalization, including thromboembolism, sac perforation, and coil migration. Permanent procedural morbidity was 2.2% ; there was no mortality. Complete occlusion was achieved in 73 (76%) aneurysms, neck remnant occlusion in 18 (18.7%) aneurysms, and incomplete occlusion in five (5.2%) aneurysms. Recanalization occurred in 8 (15.4%) of 52 coiled aneurysms that were available for follow-up conventional angiography or magnetic resonance angiography over a mean period of 13.3 months. No ruptures occurred during the follow-up period (12-79 months).

Conclusion

Endovascular coil surgery for patients with unruptured intracranial aneurysms is characterized by low procedural mortality and morbidity and has advantages in patients with poor general health, cerebral infarction, posterior circulation aneurysms, aneurysms of the proximal internal cerebral artery, and unruptured aneurysms associated with ruptured aneurysm. For the management of unruptured aneurysms, endovascular coil surgery is considered an attractive alterative option.

Intraoperative rupture in the surgical treatment of patients with intracranial aneurysms

Intraoperative rerupture (IOR) during clipping of cerebral aneurysms is a difficult complication of microneurosurgery. The aim of this study was to evaluate the incidence of IOR and analyze the strategies for controlling profound hemorrhage. A total of 165 patients with unruptured intracranial aneurysms and 46 patients with subarachnoid hemorrhage (SAH) treated surgically between April 2010 and March 2011, were reviewed. The data were collected with regard to age, sex, presence of symptoms, confounding factors and strategy for controlling intraoperative hemorrhage was analyzed in terms of location of aneurysms, timing of rupture and severity of IOR. 211 patients with 228 aneurysms were treated in this series. There were a total of six IORs which represented an IOR rate of 2.84% per patient and 2.63% per aneurysm. The highest ruptures rates occurred in patients with internal carotid artery aneurysms (25%). Surgeries in the group with ruptured aneurysms had a much higher rate of IOR compared with surgeries in the group with unruptured aneurysms. Of the six IOR aneurysms, one occurred during predissection, four during microdissection and one during clipping. One was major IOR, three were moderate and two were minor. Intraoperative rupture of an intracranial aneurysm can be potentially devastating in vascular neurosurgery. Aneurysm location, presence of SAH and surgical experience of the operating surgeon seem to be important factors affecting the incidence of IOR.     

Quality of life after treatment of unruptured intracranial aneurysms by neurosurgical clipping or by embolisation with coils. A prospective, observational study

BACKGROUND: Relatively high rates of complications occur after operation for unruptured intracranial aneurysms. Published data on endovascular treatment suggest lower rates of complications. We measured the impact of treatment of unruptured aneurysms by clipping or coiling on functional health, quality of life, and the level of anxiety and depression. METHODS: In three centres, we prospectively collected data on patients with an unruptured aneurysm who were treated by clipping or coiling. Treatment assignment was left to the discretion of the treating physicians. Before, 3 and 12 months after treatment, we used standardised questionnaires to assess functional health (Rankin Scale score), quality of life (SF-36, EuroQol), and the level of anxiety and depression (Hospital Anxiety and Depression Scale). RESULTS: Nineteen patients were treated by coiling and 32 by clipping. In the surgical group, 4 patients (12%) had a permanent complication; 36 of all 37 aneurysms (97%) were successfully clipped. Three months after operation, quality of life was worse than before operation; 12 months after operation, it had improved but had not completely returned to baseline levels. Scores for depression were higher than in the general population. In the endovascular group, no complications with permanent deficits occurred; 16 of 19 aneurysms (84%) were occluded by more than 90%. One patient died from rupture of the previously coiled aneurysm. In the others, quality of life after 3 months and after 1 year was similar to that before treatment. CONCLUSIONS: In the short term, operation of patients with an unruptured aneurysm has a considerable impact on functional health and quality of life. After 1 year, recovery occurs but it is incomplete. Coil embolisation does not affect functional health and quality of life.

Endovascular and surgical treatment of unruptured cerebral aneurysms: comparison of risks

Unruptured cerebral aneurysms are commonly treated by surgical clipping, but endovascular coil embolization is increasingly employed as an alternative. In a blinded review of unruptured aneurysms treated at our institution since 1990, we identified patients whose aneurysms were judged to be treatable by both neurosurgeons and neurointerventional radiologists. A change in Rankin Scale score of 2 or more from hospital admission to discharge, indicating a new moderate disability or worse, was predefined as the primary outcome measure. Long-term follow-up was obtained by mailed questionnaire and telephone interview. Length of stay and hospital charges were totaled for all hospitalizations, including follow-up. Sixty-eight patients treated surgically and 62 patients treated with endovascular coil embolization were considered candidates for either procedure on blinded review, and overall anticipated procedure risk was rated as identical. A larger proportion of patients in the surgical group developed a change in Rankin Scale score of 2 or more (25% of surgical patients vs 8% of endovascular patients). Total length of stay was longer (mean days: 7.7 for surgical patients vs 5.0 for endovascular patients) and hospital charges were greater (mean, $38,000 for surgical patients vs $33,400 for endovascular patients) for the surgical patients. At follow-up, an average of 3.9 years after the procedure, surgical patients were more likely to report persistent new symptoms or disability since treatment (34% of surgical patients vs 8% of endovascular patients) and a longer period for recovery to normal (50% returning to normal in 1 year for surgery and in 27 days for coil embolization). Coil embolization of unruptured cerebral aneurysms seems to be associated with significantly fewer complications than surgical clipping. More long-term data on aneurysm rupture rates are required to confirm efficacy.     

支架辅助弹簧圈栓塞颅内宽颈动脉瘤的临床研究

目的分析支架辅助弹簧圈栓塞治疗颅内宽颈动脉瘤疗效及随访结果。方法回顾性分析44例(45个)颅内宽颈动脉瘤支架辅助弹簧圈栓塞的结果,所有患者进行随访,进行改良Rankin评分(mRS)。16例患者行动脉造影或MRA随访。结果术后即刻栓塞程度:0级栓塞12个,1级栓塞22个,2级栓塞9个,3级栓塞2个。手术相关并发症7例,其中4例为血栓栓塞并发症。平均随访7.8个月,mRS 0分31例,1分5例,2分3例,3分2例,4分2例,5分1例。2个动脉瘤再通,再次栓塞治疗。结论支架辅助弹簧圈栓塞颅内宽颈动脉瘤是比较安全有效的治疗方法,血栓栓塞事件是主要并发症,抗血小板凝集不充分可能是血栓栓塞事件的主要原因。平行式方法栓塞可以提供足够的支撑力,达到致密栓塞的结果。

Long-term follow-up of intra-aneurysmal coil embolization for unruptured paraclinoid aneurysms

Abstract

Objectives: The selection of therapeutic modalities, including endovascular coil embolization and surgical clipping, for management of unruptured paraclinoid aneurysms, remains controversial. Detailed long-term outcome data for endovascular coil embolization of unruptured paraclinoid aneurysms are still lacking. Thus, we evaluated the safety and efficacy of coil embolization of unruptured paraclinoid aneurysms.

Methods: From January 1998 to July 2010, 138 patients underwent endovascular coiling for 140 unruptured paraclinoid aneurysms. Their medical records and radiologic images were reviewed retrospectively.

Results: Complications occurred in 5·7% of 140 procedures and the morbidity rate was 0·7%. Of the 140 unruptured paraclinoid aneurysms, a total of 111 aneurysms underwent follow-up imaging evaluation at 2 years or more, or showing reopening on imaging studies within 2 years (65·6±37·2 months). Multivariate analysis revealed two predictors for reopening of the aneurysms: a maximum diameter of aneurysms and a dome/neck ratio of aneurysms (P<0·05). Reopening rates of aneurysms with maximum sizes of <8, 8–10, and >10 mm were 1%, 25%, and 75%, respectively. Reopening rates were significantly different among the three groups (P<0·05). In aneurysms with a maximum diameter of 8–10 mm, there was a significant difference of dome/neck ratios between the presence and absence of reopened aneurysms (P<0·05).

Discussion: The results indicate that endovascular coil embolization is a safe and effective treatment modality in selected patients with unruptured paraclinoid aneurysms. Consideration of the aneurysm size and the dome/neck ratio could assist in the selection of therapeutic modalities for these aneurysms.

Clinical and angiographic outcomes of stent-assisted coiling of paraclinoid aneurysms: Comparison of LVIS and Neuroform stents

Paraclinoid aneurysms are mainly intradural, and are associated with a potential risk of subarachnoid hemorrhage (SAH). The application of stent-assisted coiling has been widely used in endovascular treatment of intracranial aneurysms. Here we aimed to compare clinical outcomes between low-profile visualized intraluminal support stents (LVIS) and Neuroform (NU) stents. Between January 2013 and December 2017, a total of 101 patients with 118 unruptured paraclinoid aneurysms were embolized by LVIS or NU stents. Procedure-related complications, angiography, and follow-up results were retrospectively analyzed. A total of 45 patients with 54 aneurysms received LVIS stents, and 56 patients with 64 aneurysms received NU stents. Procedure-related complication rate was 6.7% in the LVIS group and 5.4% in the NU group, with no statistical differences between groups (P = 0.511). Compared with the NU group, greater initial complete or near-complete aneurysm obliteration was achieved in the LVIS group (79.6% vs 59.4%, P = 0.0192). DSA angiography follow-up imaging of the 118 aneurysms showed that the LVIS group increased in Raymond-Roy Grade Scale I (RRGS I), however there is no statistical difference (P = 0.32). Compared with NU stents, LVIS stents may achieve greater complete or near-complete occlusion rate immediately post-operation. However, there was no difference in procedural-related complications and follow-up outcomes between LVIS and NU stent groups.
