Purpose: To estimate long-term medical resource consumption in patients with subarachnoid aneurysmal hemorrhage (SAH) receiving surgical clipping or endovascular coiling. Patients and methods: From Taiwan’s National Health Insurance Research Database, we enrolled patients with aneurysmal SAH who received clipping or coiling. After propensity score matching and adjustment for confounders, a generalized linear mixed model was used to determine significant differences in the accumulative hospital stay (days), intensive care unit (ICU) stay, and total medical cost for aneurysmal SAH, as well as possible subsequent surgical complications and recurrence. Results: The matching process yielded a final cohort of 8102 patients (4051 and 4051 in endovascular coil embolization and surgical clipping, respectively) who were eligible for further analysis. The mean accumulative hospital stay significantly differed between coiling (31.2 days) and clipping (46.8 days; p < 0.0001). After the generalized linear model adjustment of gamma distribution with a log link, compared with the surgical clipping procedure, the adjusted odds ratios (aOR; 95% confidence interval [CI]) of the medical cost of accumulative hospital stay for the endovascular coil embolization procedure was 0.63 (0.60, 0.66; p < 0·0001). The mean accumulative ICU stay significantly differed between the coiling and clipping groups (9.4 vs. 14.9 days; p < 0.0001). The aORs (95% CI) of the medical cost of accumulative ICU stay in the endovascular coil embolization group was 0.61 (0.58, 0.64; p < 0.0001). The aOR (95% CI) of the total medical cost of index hospitalization in the endovascular coil embolization group was 0·85 (0.82, 0.87; p < 0.0001). Conclusions: Medical resource consumption in the coiling group was lower than that in the clipping group.

Scarce evidence is available in Asia for estimating the long-term risk and prognostic factors of major complications such as re-rupture, vasospasm, or re-stroke for patients with aneurysmal subarachnoid hemorrhage (SAH) undergoing endovascular coil embolization or surgical clipping. This is the first head-to-head propensity score-matched study in an Asian population to demonstrate that endovascular coil embolization for aneurysmal SAH treatment is riskier than surgical clipping in terms of re-rupture, vasospasm, or re-stroke. In addition, the independent poor prognostic factors of vasospasm or re-stroke were endovascular coil embolization, male sex, older age (≥65 years; the risk of vasospasm increases with age), hypertension, congestive heart failure, diabetes, previous transient ischemic attack, or stroke in aneurysmal SAH treatment. Background: To estimate the long-term complications and prognostic factors of endovascular coil embolization or surgical clipping for patients with ruptured aneurysmal subarachnoid hemorrhage (SAH). Methods: We selected patients diagnosed with aneurysmal SAH between 1 January 2011 and 31 December 2017. Propensity score matching was performed, and Cox proportional hazards model curves were used to analyze the risk of re-rupture, vasospasm, and re-stroke in patients undergoing the different treatments. Findings: Multivariate Cox regression analysis revealed that the adjusted hazard ratio (aHR) of re-rupture for endovascular coil embolization compared with surgical clipping was 1.36 (95% confidence interval [CI]: 1.17–1.57; p < 0.0001). The aHRs of the secondary endpoints of vasospasm and re-stroke (delayed cerebral ischemia) for endovascular coil embolization compared with surgical clipping were 1.14 (1.02–1.27; p = 0.0214) and 2.04 (1.83–2.29; p < 0.0001), respectively. The independent poor prognostic factors for vasospasm and re-stroke were endovascular coil embolization, male sex, older age (≥65 years; risk increases with age), hypertension, congestive heart failure, diabetes, and previous transient ischemic attack or stroke. Interpretation: Endovascular coil embolization for aneurysmal SAH carries a higher risk than surgical clipping of both short- and long-term complications including re-rupture, vasospasm, and re-stroke.

Lower Morbidity

The endovascular treatment of renal artery aneurysms (RAAs) has lower morbidity and shorter stay lengths compared to surgical repair. Here, we describe coil packing with or without remodeling and assess outcomes and complications. We retrospectively identified the 19 consecutive preventive endovascular RAA coil embolizations done in 18 patients at our center in 2010–2020. Patient and aneurysm characteristics, technical success rate, complications, and recurrences were recorded. Mean patient age was 63 ± 13 years. The RAA was >1.5 cm in 11 cases, and in four cases, the aneurysm-to-parent artery size ratio was >2. Simple coiling was performed for 11 (57.9%) aneurysms, stent-assisted coiling for seven (36.8%) aneurysms, and balloon-assisted coiling for one (5.3%) aneurysm. Technical success rate was 100%. Complete definitive RAA exclusion was achieved with a single procedure for 17 (89.5%) aneurysms, whereas two (10.5%) aneurysms required a repeat procedure. Four minor complications occurred but resolved with no long-term consequences. No major complications occurred during the mean follow-up of 41.1 ± 29.7 months. Coil embolization by sac packing or remodeling proved very safe and effective. Together with the known lower morbidity and shorter stay length compared to open surgery, these data indicate that this endovascular procedure should become the preventive treatment of choice for RAAs.

OBJECT Intraprocedural rerupture (IPR) of intracranial aneurysms during coil embolization is associated with significant periprocedural disability and death. However, whether this morbidity and mortality are secondary to an increased risk of vasospasm and hydrocephalus is unknown. The authors undertook this study to determine the in-hospital and long-term neurological outcomes for patients with aneurysmal subarachnoid hemorrhage (SAH) treated with coil embolization who suffer aneurysm rerupture during treatment. METHODS The records of 156 patients admitted with SAH from previously untreated, ruptured, intracranial aneurysms and treated with endovascular coiling between January 2007 and January 2014 were retrospectively reviewed. Twelve patients (7.7%) experienced IPR during coil embolization. RESULTS Compared with the cohort of patients with uncomplicated coil embolization procedures, patients with aneurysm rerupture were more likely to require external ventricular drain (EVD) placement (91.7% vs 58.3%, p = 0.02) and postprocedural EVD placement (36.4% vs 7.1%, p = 0.01), to undergo permanent ventriculoperitoneal shunt placement (50.0% vs 18.8%, p = 0.02), to develop symptomatic vasospasm (50.0% vs 18.1%, p = 0.02), and to have longer lengths of hospital stay (median 21.5 days vs 15.0 days, p = 0.04). Admission Hunt and Hess, modified Fisher, and Barrow Neurological Institute grades did not differ between the 2 cohorts, nor did long-term functional neurological outcomes as assessed by the modified Rankin Scale. CONCLUSIONS Intraprocedural rerupture during coil embolization for ruptured intracranial aneurysms is associated with an increased risk of symptomatic vasospasm and need for temporary and permanent cerebrospinal fluid diversion for hydrocephalus.

Object For anterior communicating artery (ACoA) aneurysms, endovascular coil embolization constitutes a safe alternative therapeutic procedure to microsurgical clip occlusion. The authors' aim in this study was to evaluate the quality of life (QOL), cognitive function, and brain structure damage after the treatment of ruptured ACoA aneurysms in a group of patients who underwent microsurgical clipping (36 patients) compared with a reference group who underwent endovascular coiling (14 patients). Methods At 14 months posttreatment all patients underwent evaluations by independent observers. These observers evaluated global efficacy, executive functions using a frontal assessment battery of tests (Trail making test, Stroop tasks, dual task of Baddeley, verbal fluency, and Wisconsin Card Sorting test), behavior dysexecutive syndrome (the Inventaire du Syndrome Dysexécutif Comportemental questionnaire [ISDC]), and QOL by using the Reintegration To Normal Living Index. Brain damage was analyzed using MR imaging. Results In the microsurgical clipping and endovascular coiling groups, the distribution on the modified Rankin Scale (p = 0.19) and mean QOL score (85.4 vs 83.4, respectively) were similar. Moreover, the proportion of executive dysfunctions (19.4 vs 28.6%, respectively) and the mean score on the ISDC questionnaire (8.9 vs 8.5, respectively) were not significant, but verbal memory was more altered in the microsurgical clipping group (p = 0.055). Magnetic resonance imaging revealed that the incidence of local encephalomalacia and the median number of lesions per patient increased significantly in the microsurgical clipping group (p = 0.003). Conclusions In the 2 groups, no significant difference was observed regarding QOL, executive functions, and behavior. Despite the significant decrease in verbal memory after microsurgical clipping, the interdisciplinary approach remains a safe and useful strategy.

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.

Abstract OBJECTIVE Because of their anatomic configuration, middle cerebral artery (MCA) aneurysms are most often treated with surgical clipping. However, endovascular coil embolization of these aneurysms is an increasingly used alternative. We retrospectively reviewed the anatomic and clinical outcomes of patients with MCA aneurysms who underwent endovascular treatment at our institution. METHODS One hundred fifteen MCA aneurysms in 115 patients (mean age, 55.1 years) were treated by an endovascular technique from April 1990 to March 2007. Forty-eight patients (42%) presented with acute subarachnoid hemorrhage, and 67 patients (58%) had unruptured aneurysms. Fifty-three aneurysms (46%) were small with a small neck, 28 (24%) were small with a wide neck, 22 (19%) were large, and 12 (11%) were giant. RESULTS Angiographic results immediately after embolization showed complete occlusion in 53 aneurysms (46%), a neck remnant in 51 (44%), and incomplete occlusion in 3 (3%). Because of anatomic difficulties, we could not embolize 8 aneurysms (7%). Thirteen patients underwent combined treatment that included endovascular and extracranial-intracranial bypass surgery. Morbidity and mortality rates were 6.9% (8 patients) and 3% (3 patients), respectively. Procedure-related complications were encountered in 10 patients (9%). Seventy patients had long-term follow-up angiograms. Seven aneurysms (10%) were recanalized; all were large or giant. One partially embolized large aneurysm ruptured 13 months after embolization. CONCLUSION In this series, endovascular coil embolization of MCA aneurysms has morbidity and mortality rates comparable to those of conventional surgical clipping. Combined treatment of endovascular and bypass surgery can successfully treat large or giant complex fusiform MCA aneurysms.

Object The purpose of this ongoing study is to compare the safety and efficacy of microsurgical clipping and endovascular coil embolization for the treatment of acutely ruptured cerebral aneurysms and to determine if one treatment is superior to the other by examining clinical and angiographic outcomes. The authors examined the null hypothesis that no difference exists between the 2 treatment modalities in the setting of subarachnoid hemorrhage (SAH). The current report is limited to the clinical results at 1 year after treatment. Methods The authors screened 725 patients with SAH, resulting in 500 eligible patients who were enrolled prospectively in the study after giving their informed consent. Patients were assigned in an alternating fashion to surgical aneurysm clipping or endovascular coil therapy. Intake evaluations and outcome measurements were collected by nurse practitioners independent of the treating surgeons. Ultimately, 238 patients were assigned to aneurysm clipping and 233 to coil embolization. The 2 treatment groups were well matched. There were no anatomical exclusions. Crossing over was allowed, but primary outcome analysis was based on the initial treatment modality assignment. Posttreatment care was standardized for both groups. Patient outcomes at 1 year were independently assessed using the modified Rankin Scale (mRS). A poor outcome was defined as an mRS score > 2 at 1 year. The primary outcome was based on the assigned group; that is, by intent to treat. Results One year after treatment, 403 patients were available for evaluation. Of these, 358 patients had actually undergone treatment. The remainder either died before treatment or had no identifiable source of SAH. A poor outcome (mRS score > 2) was observed in 33.7% of the patients assigned to aneurysm clipping and in 23.2% of the patients assigned to coil embolization (OR 1.68, 95% CI 1.08–2.61; p = 0.02). Of treated patients assigned to the coil group, 124 (62.3%) of the 199 who were eligible for any treatment actually received endovascular coil embolization. Patients who crossed over from coil to clip treatment fared worse than patients assigned to coil embolization, but no worse than patients assigned to clip occlusion. No patient treated by coil embolization suffered a recurrent hemorrhage. Conclusions One year after treatment, a policy of intent to treat favoring coil embolization resulted in fewer poor outcomes than clip occlusion. Although most aneurysms assigned to the coil treatment group were treated by coil embolization, a substantial number crossed over to surgical clipping. Although a policy of intent to treat favoring coil embolization resulted in fewer poor outcomes at 1 year, it remains important that high-quality surgical clipping be available as an alternative treatment modality.
