Ruptured Intracranial Aneurysms

Endovascular treatment has assumed a role of first choice in the management of ruptured intracranial aneurysms. We describe the clinical and morphological data after the treatment of 258 ruptured intracranial aneurysms in 241 patients, in order to evaluate the safety and the efficacy of the endovascular treatment. Two hundred and forty-one patients with saccular ruptured aneurysms were treated at our institution between 2000 and 2005. After the endovascular treatment a clinical and angiographic follow-up was conducted. The clinical follow-up was carried out with a medical examination and telephonic interviews and mRS was used for evaluation. Two hundred and forty-nine acutely ruptured aneurysms were successfully treated and immediately after the endovascular procedure 81.9% of the aneurysms resulted completely occluded, 12.1% had a residual neck and 6% revealed a residual sac. The evolution of each grade was evaluated at six months and two years. During the follow-up we observed five early and one late re-bleedings. Twenty-four patients underwent a second procedure. After the discharge and up to ten years 73.1% of patients had a good clinical outcome (mRS0–1), 8.9% died and the remainder showed moderate-severe disability (mRS2–3). The long-term stability of the anatomical result is a critical issue of this approach because eventual re-bleedings may occur even after several months or years. A careful clinical and radiological follow-up for up to two years after the embolization may prevent recurrences but may not be sufficient.

Introduction Stent-assisted coiling has widened indications and improved stability of endovascular treatment of intracranial aneurysms. However, stent-assisted coiling is usually not used to treat acutely ruptured intracranial aneurysms to avoid antiplatelet therapy. The objective of this study is to evaluate a strategy of staged endovascular treatment of ruptured intracranial aneurysms including coiling at the acute phase with complementary stenting with or without coiling at the subacute phase. Material and methods Between 2012 and 2017, we retrospectively identified, in our prospectively maintained database, all patients treated for a ruptured intracranial aneurysm based on this staged stenting strategy. Clinical charts and imaging follow-up were analyzed to assess the procedural safety and feasibility as well as clinical and anatomical outcome. Results We identified 23 patients with 23 intracranial aneurysms including 15 (65.2%) women with a mean age of 50 years (range 24–69 years). No rebleeding occurred during the mean delay of 24.3 days between initial coiling and stenting. All procedures were successful and additional coiling was performed in 5/23 procedures (21.7%). Clinical status was unchanged in all patients. At follow-up, the modified Rankin scale was graded 0 in 19/23 (82.6%), 1 in 2/23 (8.7%), and 2 in 2/23 (8.7%) patients, respectively. The rate of complete occlusion rose from 30.4% before the stenting procedure to 52.2% immediately after and 72.7% at follow-up. Conclusion This strategy of early staged stenting in selected patients is safe and improves immediate intracranial aneurysm occlusion and long-term stability in this population at high risk of intracranial aneurysm recurrence with coiling alone.

Abstract INTRODUCTION ISAT demonstrated that coiling is effective for aneurysm treatment in subarachnoid hemorrhage (SAH); however, complete occlusion of wide-necked aneurysms frequently requires adjuvants relatively contraindicated in SAH. As such, a limited “dome occlusive” strategy is often pursued in the setting of SAH. We report a single institution series of coiling of acutely ruptured aneurysms followed by delayed flow diversion for definitive, curative occlusion. METHODS A prospectively collected IRB-approved database was screened for patients with aneurysmal SAH who were initially treated by coil embolization followed by planned flow diversion at a single academic medical institution. Peri-procedural outcomes, complications, and angiographic follow-up were analyzed. RESULTS >50 patients underwent both acute coiling followed by delayed, planned flow diversion. Average aneurysm size on initial presentation was 9.5 mm. Common aneurysm locations included Pcomm (36%), Acomm (30%), MCA (10%), ACA (10%), and vertebral (5%). Dome occlusion was achieved in all cases following initial coiling. Second-stage implantation of a flow diverting stent was achieved in 49/50 cases (98%). Follow-up angiography was available for 33/50 patients (66%), with mean follow-up of 11 months. 27 patients (82%) had complete angiographic occlusion at last follow up. All patients with residual filling at follow-up still had dome occlusion. There were no mortalities (0%). Major complication rate for stage I coiling was 2% (1 patient with intra-procedural aneurysm re-rupture causing increase in a previous ICH). Major complication rate for stage 2 flow diversion was 2% (1 patient with ischemic stroke following noncompliance with dual antiplatelet regimen). Minor complications occurred in 2 additional patients (4%) with transient neurological deficits. CONCLUSION Staged endovascular treatment of ruptured intracranial aneurysms with acute dome-occlusive coil embolization followed by delayed flow diversion is a safe and effective treatment strategy.

Long-term follow-up studies after endovascular treatment for intracranial aneurysm are still rare and inconclusive. The aim of this study was to assess the long-term clinical and angiographic outcome of patients with endovascularly treated aneurysms. The clinical outcome of all 185 patients with endovascularly treated aneurysms were analyzed and 77 out of 122 surviving patients were examined with MRI and MRA nine to 16 years (mean 11 years) after the initial endovascular treatment. Sixty-three patients were deceased at the time of follow-up. The cause of death was aneurysm-related in 34 (54%) patients. The annual rebleeding rate from the treated aneurysms was 1.3% in the ruptured group and 0.1% in the unruptured group. In long-term follow-up MRA 18 aneurysms (53%) were graded as complete, 11 aneurysms (32%) had neck remnants and five aneurysms (15%) were incompletely occluded in the ruptured group. The occlusion grade was lower in the unruptured group with 20 aneurysms (41%) graded as complete, 11 (22%) had neck remnants and 18 (37%) were incomplete. However, only three aneurysms were unstable during the follow-up period and needed retreatment. Endovascular treatment of unruptured aneurysms showed incomplete angiographic outcome in 37% of cases. However, the annual bleeding rate was as low as 0.1%. Endovascular treatment of ruptured aneurysms showed incomplete angiographic outcome in 15% of cases and the annual rebleeding rate was 1,3%.

Abstract Purpose To investigate the long-term clinical and angiographic outcomes and their related predictors in endovascular treatment (EVT) of small (<5 mm) ruptured intracranial aneurysms (SRA). Methods The study retrospectively reviewed patients with SRAs who underwent EVT between September 2011 and December 2016 in two Chinese stroke centers. Medical charts and telephone call follow-up were used to identify the overall unfavorable clinical outcomes (OUCO, modified Rankin score ≤2) and any recanalization or retreatment. The independent predictors of OUCO and recanalization were studied using univariate and multivariate analyses. Multivariate Cox proportional hazards models were used to identify the predictors of retreatment. Results In this study 272 SRAs were included with a median follow-up period of 5.0 years (interquartile range 3.5–6.5 years) and 231 patients with over 1171 aneurysm-years were contacted. Among these, OUCO, recanalization, and retreatment occurred in 20 (7.4%), 24 (12.8%), and 11 (7.1%) patients, respectively. Aneurysms accompanied by parent vessel stenosis (AAPVS), high Hunt-Hess grade, high Fisher grade, and intraoperative thrombogenesis in the parent artery (ITPA) were the independent predictors of OUCO. A wide neck was found to be a predictor of recanalization. The 11 retreatments included 1 case of surgical clipping, 6 cases of coiling, and 4 cases of stent-assisted coiling. A wide neck and AAPVS were the related predictors. Conclusion The present study demonstrated relatively favorable clinical and angiographic outcomes in EVT of SRAs in long-term follow-up of up to 5 years. THE AAPVS, as a morphological indicator of the parent artery for both OUCO and retreatment, needs further validation.

Mean Time

We evaluate endovascular treatment (EVT) as an option to deal with multiple intracranial aneurysms(MA). From 1994 to 2001, 24 patients underwent EVT for 59 MA. Patients were followed-up clinically and angiographically in a period ranging from 6 to 93 months (mean time of 22.2) and from 4 to 69 months (mean time of 19.3), respectively. Ten patients (41.6%) were treated either by EVT (n=7, 29, 16%) or by mixed treatment (EVT and surgery; n=3, 12.5%). Reasons for treating just ruptured aneurysms: six (25%) had aneurysms smaller than 5 mm; three (12.5%) deaths; two (8.33%) were in the subacute period; two (8.33%) lost to follow-up; one (4.17%) authorised no procedure. No rebleeding was detected at the clinical follow-up, but there were five deaths. At immediate arteriographic control: 28 (85%) aneurysms were fully occluded, four (12%) with neck flow and one (03%) with sac flow. For 20 aneurysms followed-up: stability of occlusion was reached in seven cases (35%) and repermeabilization in 13 (65%). Management of recanalization was close arteriography in seven (54%), re-embolization in five (38%) and surgery in one (08%). When treating MA, EVT is advisable either alone or in mixed therapy. As a high degree of repermeabilization was disclosed, strict arteriographic control is required. The mechanisms underlying aneurysmal formation may be also involved in the recanalization phenomenon, a possible new manifestation of the fragility of the arterial wall.

Abstract OBJECTIVE: With a globally aging population, it is imperative to develop specific treatment strategies for intracranial aneurysms in the elderly. However, the optimal management of intracranial aneurysms in the elderly remains controversial, particularly for the unruptured aneurysms. Although endovascular treatment is increasingly being used for the management of aneurysms, large endovascular series in the elderly population are relatively lacking, especially with regard to the unruptured aneurysms. We present our single-center endovascular experience in treating intracranial aneurysms in 63 consecutive patients 70 years of age and older. METHODS: Between November 1998 and December 2003, among a total of 990 patients with intracranial aneurysms treated endovascularly at our center, 63 patients (6%) were 70 years of age or older. Forty-one patients presented with subarachnoid hemorrhage (SAH), and 22 presented with symptomatic unruptured aneurysms. A total of 84 aneurysms were detected in these 63 patients. Only those responsible for either the subarachnoid hemorrhage or clinical symptoms (68 aneurysms) were treated. The aneurysm characteristics, endovascular procedures and techniques, angiographic and clinical outcomes, and complications were reviewed. RESULTS: Selective embolization failed in three aneurysms (4%). In the remaining 65 aneurysms, complete occlusion was achieved in 33 aneurysms (51%), neck remnant was observed in 17 aneurysms (27%), and residual aneurysmal filling was observed in six aneurysms (9%). Parent vessel occlusion was used in the treatment of nine aneurysms (13%). Thirteen procedure-related complications occurred (19%), six of which resulted in clinical complications (9%). Nine deaths (14%) occurred; three (5%) were directly related to the endovascular procedures, and six (9%) were related to the medical complications of SAH. The remaining 54 patients had a mean clinical follow-up time of 13 months (range, 1–47 mo). Ninety-one percent (20 out of 22) of the patients with unruptured aneurysms and 89% (25/28) of the patients with low-grade (Hunt and Hess Grade I and II) ruptured aneurysms achieved excellent outcomes (modified Rankin Scale score, 0–1), whereas 77% (10 out of 13) of the patients with high-grade (Hunt and Hess Grade ≥ III) ruptured aneurysms either died or had very poor outcomes (modified Rankin Scale score, 4–5). Angiographic follow-up (mean, 11 mo; range, 3–38 mo) was obtained in 34 of the 54 living patients (63%). Two aneurysms demonstrated minor changes that required no further treatment (5%). Five aneurysms showed major recurrences (17%), all of which were successfully retreated endovascularly. CONCLUSION: The elderly patients should merit strong consideration for endovascular treatment of both ruptured and symptomatic unruptured intracranial aneurysms. However, in elderly patients with high-grade subarachnoid hemorrhage, morbidity and mortality rates remain high.

Methodological Comparison

Objective Incomplete aneurysm occlusions and re-treatment rates of 52 and 10–30%, respectively, have been reported following endovascular treatment of intracranial aneurysms, raising clinical concerns regarding procedural efficacy. We compare residual, recurrence and re-treatment rates subject to different endovascular techniques in both ruptured and unruptured intracranial aneurysms at a comprehensive state-wide tertiary neurovascular centre in Australia. Methods Medical records, procedural and follow-up imaging studies of all patients who underwent endovascular treatment for intracranial aneurysms between July 2010 and July 2017 were reviewed retrospectively. Residuals, recurrences and re-treatment rates were assessed regarding initial aneurysm rupture status and applied endovascular technique: primary coiling, balloon- and stent-assisted coiling and flow diversion. Results Among 233 aneurysms, residual, recurrence and re-treatment rates were 27, 11.2 and 9.4%, respectively. Compared with unruptured aneurysms, similar residual and recurrence (p > .05), but higher re-treatment rates (4.5% vs. 19%; p < .001) were found for ruptured aneurysms. Residual, recurrence and re-treatment rates were: 13.3, 16 and 12% for primary coiling; 12, 12 and 10.7% for balloon-assisted coiling; 14.9, 7.5 and 4.5% for stent-assisted coiling; 91.9, 0 and 5.4% for flow diversion. Stent-assistance and flow-diversion were associated with lower recurrence and re-treatment rates, when compared with primary- and balloon-assisted coiling (p < .05). Conclusions Residuals and recurrences after endovascular treatment of intracranial aneurysms are less common than previously reported. Stent assistance and flow diversion seem associated with reduced recurrence- and re-treatment rates, when compared with primary- and balloon-assisted coiling. Restrained use of stents in ruptured aneurysms may be a contributing factor for higher recurrence/retreatment rates compared to unruptured aneurysms.

Abstract BACKGROUND: Stent-assisted coiling (SAC) and balloon-assisted coiling (BAC) are 2 well-established techniques for the treatment of complex and wide-necked intracranial aneurysms. Most clinicians are reluctant to perform SAC in the setting of subarachnoid hemorrhage because of the need for dual antiplatelet therapy. OBJECTIVE: To compare the safety and efficacy of SAC and BAC in acutely ruptured complex and wide-necked aneurysms. METHODS: Forty-four patients underwent SAC and 40 underwent BAC. Patients treated with SAC received antiplatelet medications. Perioperative adverse events and outcomes at follow-up (mean, 7.4 months) were retrospectively studied. RESULTS: The 2 groups were statistically comparable with respect to all baseline characteristics except for older age in SAC patients (65.6 vs 56.5 years; P = .009). A higher proportion of SAC patients also had poor Hunt and Hess grades (III-V; 70.5% vs 55%; P = .l4). Hemorrhagic, thromboembolic, and overall procedural complications occurred in 6.8%, 11.4%, and 18.2% of the SAC group vs 2.5%, 7.5%, and 10% of the BAC group, respectively (P = .5, P = .6, P = .3, respectively). Favorable outcomes (modified Rankin Scale score 0-2) at follow-up were seen in 61.0% of the SAC group vs 77% of the BAC group (P = .1). In multivariable analysis, after controlling for differences in baseline characteristics, the type of treatment was not a predictor of procedural complications or clinical outcome. CONCLUSION: In this study, procedural complications and clinical outcomes did not differ significantly between SAC and BAC in patients with acutely ruptured aneurysms. SAC may be an acceptable alternative to BAC for complex aneurysms in the acute phase of subarachnoid hemorrhage.

Optimal Treatment Strategy

Ruptured intracranial aneurysms are extremely rare in infants. The optimal treatment strategy is not well established. Both microsurgical and endovascular techniques and strategies have been tried, and in the literature there is a significant variability in outcome. The authors report the presentation and successful endovascular treatment of a large, ruptured, middle cerebral artery bifurcation aneurysm in a 5-week-old girl, one of only a few reported in the literature. Clinical and radiological findings at follow-up are also presented. The authors then review the literature on aneurysmal subarachnoid hemorrhage in infants, with particular regard to outcome after either endovascular or open surgical management. They also provide recommendations for follow-up in pediatric patients whose intracranial aneurysms have been treated with coil embolization.

ABSTRACT BACKGROUND: The pipeline embolization device (PED) has been used for treatment of unruptured aneurysms. Little is known about the use of the PED in ruptured aneurysms. OBJECTIVE: To assess the safety and efficacy of the PED in ruptured intracranial aneurysms. METHODS: This is a case series with prospective data collection on 20 patients with freshly ruptured aneurysms who were treated with PED (with or without adjunctive coiling) at 2 cerebrovascular centers. Patients were loaded with aspirin and clopidogrel or received an infusion of tirofiban intraoperatively. RESULTS: Hunt and Hess grades were I in 7 patients (35%), II in 9 (45%), and III in 4 (20%). The mean duration from hemorrhage to PED placement was 7 ± 7.0 days. A single device was used in all but 1 patient (95%). The procedure was staged in 20%. There was only 1 complication (5%); this was a fatal intraoperative aneurysm dome rupture that occurred during adjunctive coil deployment. Adjunctive coiling was used in 30%. No patient required an invasive procedure after PED placement. Follow-up angiography (mean, 5.3 ± 4.2 months; range, 2-12 months) showed 100% occlusion in 12 (80%) and incomplete occlusion in 3 patients (20%). At latest follow-up, 19 patients achieved a favorable outcome (modified rankin scale 0–2). CONCLUSION: In our preliminary experience, treatment of ruptured aneurysms with the PED was associated with low complication rates, high occlusion rates, and favorable outcomes. These findings suggest that PED may be a safe and effective option for patients with favorable Hunt and Hess grades and aneurysms difficult to treat with conventional methods.
