First Choice

Since October, 1997, endovascular embolization using GDC has been our primary treatment for ruptured cerebral aneurysms in the acute stage. According to our protocol, an aneurysm more than 3 mm in diameter, without a wide-neck or massive intracranial hematoma is indicated for endovascular therapy. Under this protocol, we experienced 35 consecutive patients with aneurysmal subarachnoid hemorrhage, and 22 of them (62.8%) were treated endovascularly. The most common reason for the contra-indication of coil embolization was wide-necked aneurysm (9 cases). We experienced two cases with embolic stroke and one case with post-embolization hemorrhage as a complication after endovascular treatment. Morbidity rate due to the complications was 9.1%. In conclusion, a system that allows both surgical and endovascular treatments to be performed in any given case is necessary for the appropriate treatment of ruptured aneurysm. In order to avoid ischemic embolic complications, postoperative anticoagulation therapy is crucial. The safety of coil embolization for very thin-walled aneurysm is questionable.

Treatment of very small ruptured cerebral aneurysms (< 2 mm) continues to present a challenge. These lesions are difficult to treat both with neurosurgical and endovascular techniques. A neurosurgical approach is still the treatment of choice for these lesions at many centers because of high rupture rates related to endovascular treatment; however, there are clinical circumstances in which the neurosurgical option cannot be offered. In their review of the literature, the authors did not find any series reporting endovascular treatment of these very small aneurysms. In the present study, the authors report their experience with the endovascular treatment of a series of 4 ruptured aneurysms smaller than 2 mm from neck to dome. They describe their technique of using a remodelling balloon to stabilize the tip of the microcatheter in the neck of the aneurysm without entering it at any time, and of inserting the coil from outside the sac to minimize the risk of intraoperative rupture, which is very high when conventional endovascular embolization is performed.

The present series provides a balanced overview of the treatment of aneurysms in surgical clipping and coil embolization. Between January 2004 and March 2006, 76 consecutive patients with cerebral aneurysms underwent endovascular embolization and/or surgical clipping. Of these, 42 patients suffered an aneurysmal subarachnoid hemorrhage (SAH), while the remaining 34 patients had nonruptured cerebral aneurysms. Of the 23 surgically treated patients, 17 (73.9%) achieved a favorable outcome. Of the 19 patients who underwent endovascular embolization, 12 (63.2%) achieved a favorable outcome. Three patients (15.8%) who underwent endovascular embolization needed to undergo re-treatments, while no re-treatment was needed in the surgically treated patients. Of the 34 nonruptured aneurysms, 12 (35.3%) were treated using surgical clipping, while 22 (64.7%) underwent endovascular embolization. The complication rates of the two treatment modalities demonstrated no significant difference. A combined microsurgical-endovascular team approach is thus considered to provide the most effective means to achieve favorable outcomes for patients with cerebral aneurysms.

Mycotic Aneurysms

Background: Mycotic intracranial aneurysms are rare with primary treatment focusing on underlying infection to reduce the high mortality rates. Treating these aneurysms remains challenging and obliteration procedures without sacrificing the parent artery often fail due to the fusiform and fragile aneurysm wall. Objective: To determine the outcomes associated with endovascular embolization in patients with mycotic intracranial aneurysms using a large nationally representative sample. Methods: We determined the frequency of endovascular and surgical procedures performed in patients with mycotic intracranial aneurysms and associated in-hospital outcomes using data from the Nationwide Inpatient Survey (NIS) data files from 2002 to 2009. All the in-hospital outcomes were analyzed after adjusting for potential confounders using multivariate logistic regression analysis. Results: Of the 1,915 patients admitted with the diagnosis of infected “mycotic” aneurysms, 83 (4.3%) underwent endovascular embolization, and 59 (3.1%) underwent surgical treatment. In mycotic aneurysms treated with endovascular treatment compared to surgical treatment, discharge outcomes were better with higher rates of minimal disability self-care (40% vs. 23.7% p=0.2436), and lower rates of moderate-severe disability (36% vs. 40% p=0.7874), and in-hospital deaths death (22.9 vs. 35.2 p= 0.3608). After adjusting for age, gender, and hospital teaching status, discharge mortality after endovascular treatment was not inferior to surgical treatment (odds ratio [OR] 1.58, 95% confidence interval [CI] 0.14 - 17.9) or those treated medically (OR 0.56, 95% CI 0.132 - 2.36). Conclusion: Endovascular embolization for mycotic intracranial aneurysms provides comparable outcomes to surgical treatment and should be considered whenever feasible when aneurysm obliteration is indicated.

Object Endovascular coiling and surgical clipping are viable treatment options of cerebral aneurysms. Outcome data of these treatments in children are limited. The objective of this study was to determine hospital mortality and complication rates associated with surgical clipping and coil embolization of cerebral aneurysms in children, and to evaluate the trend of hospitals' use of these treatments. Methods The authors identified a cohort of children admitted with the diagnoses of cerebral aneurysms and aneurysmal subarachnoid hemorrhage from the Kids' Inpatient Database for the years 1998 through 2009. Hospital-associated complications and in-hospital mortality were compared between the treatment groups and stratified by aneurysmal rupture status. A multivariate regression analysis was used to identify independent variables associated with in-hospital mortality. The Cochrane-Armitage test was used to assess the trend of hospital use of these operations. Results A total of 1120 children were included in this analysis; 200 (18%) underwent aneurysmal clipping and 920 (82%) underwent endovascular coiling. Overall in-hospital mortality was higher in the surgical clipping group compared with the coil embolization group (6.09% vs 1.65%, respectively; adjusted odds ratio [OR] 2.52, 95% CI 0.97–6.53, p = 0.05). The risk of postoperative stroke or hemorrhage was similar between the two treatment groups (p = 0.86). Pulmonary complications and systemic infection were higher in the surgical clipping population (p < 0.05). The rate of US hospitals' use of endovascular coiling has significantly increased over the years included in this study (p < 0.0001). Teaching hospitals were associated with a lower risk of death (OR 0.13, 95% CI 0.03–0.46; p = 0.001). Conclusions Although both treatments are valid, endovascular coiling was associated with fewer deaths and shorter hospital stays than clip placement. The trend of hospitals' use of coiling operations has increased in recent years.

Objective Intracranial aneurysms treated with endovascular coil embolization may recur. We investigated the factors affecting aneurysmal recurrence after embolization and effects of endovascular retreatment within 1 year. Methods In 3 years, 1,335 patients with 1,385 intracranial aneurysms were treated with coil embolization. Factors affecting aneurysm recurrence and the effects of endovascular retreatment were analyzed. Results Angiography immediately following embolization showed total occlusion in 1,030 aneurysms (74.4%), neck remnant in 207 (14.9%), and partial occlusion in 148 (10.7%), with a total peri-procedure complication rate of 4.2%. Overall, 145 patients with 151 aneurysms recurred within 1 year and the other 1,234 aneurysms remained occluded (89.1%). A significant (p < 0.05) difference existed in aneurysm size, rupture status, use of stent and immediate occlusion outcome between the two groups, with significantly (p < 0.05) lower recurrence rates in aneurysms with smaller sizes, no rupture and stent-assistance coiling. Neck remnant, partial occlusion, coiling without stent assistance, large and giant aneurysms were significant (p < 0.05) risk factors for aneurysm recurrence during the first year. The rate of recurrence was 4.7% (11/232) in aneurysms with total occlusion and 35.9% (23/64) in aneurysms with neck remnant and partial occlusion. Of the 34 recurrent aneurysms, 6 were re-embolized with detachable coils alone, 12 with stent-assisted coiling, 8 with balloon-assisted embolization, and the remaining 8 aneurysms with covered stents, resulting in total occlusion in 28 aneurysms and neck remnant in 6. Conclusion Recurrence of previously-coiled cerebral aneurysms is significantly affected by aneurysm size, use of stent and degree of immediate occlusion. Endovascular retreatment with balloon-or stent-assisted techniques or with covered stents can be safe and effective for recurrent cerebral aneurysms.

Wide Neck

Coil embolization is the most common endovascular treatment for cerebral aneurysms at many centers [1]. Nevertheless, the coiling of wide-neck aneurysms is a challenge. Incomplete filling of the aneurysmal sac due to coil configuration challenges and aneurysmal growth can often lead to recurrence. To assist treatment with coils, clinicians may deploy a high porosity stent in a staged process to act as a supporting bridge for coils. The stent is first deployed across the aneurysmal neck, and multiple coils are then deployed into the aneurysmal sac 6–8 weeks later [2]. Under certain circumstances, coil deployment is not possible and high porosity stents alone are used for treatment [2–3].

Abstract OBJECTIVE To document a unique technical issue with a relatively newly released intravascular stent used for adjunctive treatment of wide-necked cerebral aneurysms. CLINICAL PRESENTATION A 48-year-old woman with a sister who had a large unruptured wide-necked basilar aneurysm underwent screening evaluation that revealed a nearly identical aneurysm. She also harbored small unruptured right superior cerebellar and left anterior cerebral artery aneurysms. INTERVENTION Endovascular treatment of the 11.5-mm basilar aneurysm was performed in a staged manner. Stent placement was performed first, followed by delayed coil embolization of the aneurysm 9 weeks later. Follow-up angiography at the time of the second procedure revealed significant spontaneous proximal migration of the Enterprise Vascular Reconstruction Device and Delivery System (Cordis Neurovascular, Inc., Miami Lakes, FL) with the distal extent of the device migrating from the right P2 segment into the neck of the aneurysm. Coil embolization was performed despite migration of the vascular reconstruction device. CONCLUSION The use of stents in the endovascular treatment of cerebral aneurysms has vastly improved our ability to treat complex lesions. Technical issues remain with these devices, and description of this event may alter the way we use the Enterprise Vascular Reconstruction Device and Delivery System in terms of staging procedures, and when evaluating the particular vascular anatomy of the individual patient with special attention to parent artery vessel size.

Abstract Background Wide-necked cerebral aneurysms in the setting of acute subarachnoid hemorrhage (SAH) remain difficult to treat with endovascular methods despite recent progress in the neuroendovascular field. Objective To evaluate the effectiveness and safety of the Comaneci device (Rapid Medical, Israel) in endovascular coil embolization of acutely ruptured, wide-necked sidewall, or bifurcation cerebral aneurysms. Methods We retrospectively reviewed 45 anterior communicating artery, 24 internal carotid artery, 21 middle cerebral artery bifurcation, 15 anterior cerebral artery, and 13 posterior circulation aneurysms, which were treated using Comaneci-assisted coil embolization from August 2017 to January 2019. We evaluated procedural complications, clinical outcomes, and mid-term angiographic follow-up. Immediate and 90 d-clinical outcome and radiological follow-up were obtained in all patients. Results Comaneci-assisted coil embolization was performed in 118 acutely ruptured aneurysms. The technique was carried out successfully in all cases. Simultaneous application of 2 separated Comaneci devices was performed in 8/118 cases (6.77%). Periprocedural thromboembolic complications related to the device were seen in 7/118 cases (5.93%) and severe vasospasm of the parent artery after manipulation of the Comaneci device occurred in 5/118 cases (4.2%). The procedural-related morbidity rate was 2.54%, and there was no procedural related mortality. Among the available survivors, angiographic follow-ups were obtained at 3 and 6 mo, and complete aneurysmal obliteration was confirmed in 81/112 (72.3%) and 75/112 (66.9%) cases, respectively. Mid-term follow-up reviewed total recanalization rate of 14.28%. Conclusion Comaneci-assisted embolization of wide-necked intracranial aneurysms in patients presenting with acute SAH is associated with high procedural safety and adequate occlusion rates. Furthermore, dual antiplatelet therapy can be safely avoided in this patient group.

Four cases of ruptured aneurysmal subarachnoid hemorrhage (SAH) presented with severe neurogenic pulmonary edema (NPE). On admission, two patients were grade IV and two were grade V according to Hunt and Hess grading. All patients needed respiratory management with the assistance of a ventilator. Three of them underwent endovascular treatment for the ruptured aneurysms within three days from onset after ensuring hemodynamic stability. Immediately after the endovascular treatment, lumbar spinal drainage was inserted in all the patients. The pulmonary edema findings disappeared rapidly after the respiratory management. The results were good recovery in two, and moderate disability in two. We concluded that early embolization of ruptured aneurysm and placement of spinal drainage is a satisfactory option for severe SAH with NPE.
