Background and aims: The role of statins in unruptured intracranial aneurysm (UIA) growth and rupture remains ambiguous. This study sought to determine whether atorvastatin is associated with aneurysm growth and rupture in patients harboring UIA <7 mm. Methods: This prospective, multicenter cohort study consecutively enrolled patients with concurrent UIA <7 mm and ischemic cerebrovascular disease from four hospitals between 2016 and 2019. Baseline and follow-up patient information was recorded. Because of the strong anti-inflammatory effect of aspirin, patients using aspirin were excluded. Patients taking atorvastatin 20 mg daily were atorvastatin users. The primary and exploratory endpoints were aneurysm rupture and growth, respectively. Results: Among the 1087 enrolled patients, 489 (45.0%) took atorvastatin, and 598 (55%) took no atorvastatin. After a mean follow-up duration of 33.0 ± 12.5 months, six (1.2%) and five (0.8%) aneurysms ruptured in atorvastatin and non-atorvastatin groups, respectively. In the adjusted multivariate Cox analysis, UIA sized 5 to <7 mm, current smoker, and uncontrolled hypertension were associated with aneurysm rupture, whereas atorvastatin [adjusted hazard ratio (HR) 1.495, 95% confidence interval (CI) 0.417–5.356, p = 0.537] was not. Of 159 patients who had follow-up imaging, 34 (21.4%) took atorvastatin and 125 (78.6%) took no atorvastatin. Aneurysm growth occurred in five (14.7%) and 21 (16.8%) patients in atorvastatin and non-atorvastatin groups (mean follow-up: 20.2 ± 12.9 months), respectively. In the adjusted multivariate Cox analysis, UIAs sized 5 to <7 mm and uncontrolled hypertension were associated with a high growth rate; atorvastatin (adjusted HR 0.151, 95% CI 0.031–0.729, p = 0.019) was associated with a reduced growth rate. Conclusions: We conclude atorvastatin use is associated with a reduced risk of UIA growth, whereas atorvastatin is not associated with UIA rupture.

Unruptured Intracranial Aneurysms

ObjectiveWe initiated a multicenter, prospective cohort study to test the hypothesis that aspirin is safe for patients with ischemic cerebrovascular disease (ICVD) harboring unruptured intracranial aneurysms (UIAs) <7 mm.MethodsThis prospective, multicenter cohort study consecutively enrolled 1,866 eligible patients with ICVD harboring UIAs <7 mm in diameter from 4 hospitals between January 2016 and August 2019. Baseline and follow-up patient information, including the use of aspirin, was recorded. The primary endpoint was aneurysm rupture.ResultsAfter a total of 4,411.4 person-years, 643 (37.2%) patients continuously received aspirin treatment. Of all included patients, rupture occurred in 12 (0.7%). The incidence rate for rupture (IRR) was 0.27 (95% confidence interval [CI] 0.15–0.48) per 100 person-years. The IRRs were 0.39 (95% CI 0.21–0.72) and 0.06 (95% CI 0.010–0.45) per 100 person-years for the nonaspirin and aspirin groups, respectively. In the multivariate analysis, uncontrolled hypertension and UIAs 5 to <7 mm were associated with a high rate of aneurysm rupture, whereas aspirin use was associated with a low rate of aneurysm rupture. Compared with other groups, the high-risk group (UIAs 5 to <7 mm with concurrent uncontrolled hypertension) without aspirin had higher IRRs.ConclusionAspirin is a safe treatment for patients with concurrent small UIAs and ICVD. Patients who are not taking aspirin in the high-risk group warrant intensive surveillance.ClinicalTrials.gov IdentifierNCT02846259.Classification of EvidenceThis study provides Class III evidence that for patients harboring UIAs <7 mm with ICVD, aspirin does not increase the risk of aneurysm rupture.

Background and Purpose— Growth of an intracranial aneurysm occurs in around 10% of patients at 2-year follow-up imaging and may be associated with aneurysm rupture. We investigated whether PHASES, a score providing absolute risks of aneurysm rupture based on 6 easily retrievable risk factors, also predicts aneurysm growth. Methods— In a multicenter cohort of patients with unruptured intracranial aneurysms and follow-up imaging with computed tomography angiography or magnetic resonance angiography, we performed univariable and multivariable Cox regression analyses for the predictors of the PHASES score at baseline, with aneurysm growth as outcome. We calculated hazard ratios and corresponding 95% confidence intervals (CI), with the PHASES score as continuous variable and after division into quartiles. Results— We included 557 patients with 734 unruptured aneurysms. Eighty-nine (12%) aneurysms in 87 patients showed growth during a median follow-up of 2.7 patient-years (range 0.5–10.8). Per point increase in PHASES score, hazard ratio for aneurysm growth was 1.32 (95% CI, 1.22–1.43). With the lowest quartile of the PHASES score (0–1) as reference, hazard ratios were for the second (PHASES 2–3) 1.07 (95% CI, 0.49–2.32), the third (PHASES 4) 2.29 (95% CI, 1.05–4.95), and the fourth quartile (PHASES 5–14) 2.85 (95% CI, 1.43–5.67). Conclusions— Higher PHASES scores were associated with an increased risk of aneurysm growth. Because higher PHASES scores also predict aneurysm rupture, our findings suggest that aneurysm growth can be used as surrogate outcome measure of aneurysm rupture in follow-up studies on risk prediction or interventions aimed to reduce the risk of rupture.

Introduction: Previous studies have shown that unruptured intracranial aneurysm (UIA) growth and rupture are strongly associated with each other, with an increasing number of aneurysms followed clinically, especially UIA smaller than 7 mm. Hypothesis: Patient-specific and aneurysm-specific clinical and demographic features can predict growth and growth rates of UIA. Methods: We studied a cohort of 293 individuals diagnosed with a total of 409 intracranial aneurysms followed for an average of 27.4 months. Associations with aneurysm growth and growth rate were identified for both patient- and aneurysm-specific variables. Growth was defined as a size increase greater than 0.6 mm, with growth rate (mm/year) determined from the change in size of the aneurysm between the first and last measurement. Results: Mean initial size at diagnosis was significantly associated with risk of growth (OR: 1.09, 95% CI: 1.01-1.18, p=0.036), as was diagnosis of multiple aneurysms (OR: 2.01, 95% CI: 1.00-4.04, p=0.048) and having a positive family history (OR: 4.25, 95% CI: 1.18-15.3, p=0.041). Diagnosis of coronary artery disease (CAD) (p<0.001), diabetes (p=0.041), and gender (p=0.014) were significant for growth rate. Differences were observed for aneurysms located in different vessels, with an increased occurrence of growth at M-Bifurcation (p=0.015 vs. other MCA sites) and a high growth rate for those located in the BA trunk (p=0.0033 vs. other VABA sites). Conclusions: This analysis takes advantage of a large longitudinal cohort with multiple follow-up measurements to provide further insight regarding the characteristics of UIA growth behavior. While our data further confirm that aneurysm rupture and growth share a similar set of risk factors (size, multiplicity and family history), we additionally that found patients with CAD or diabetes had a higher aneurysm growth rate, and therefore might require more frequent follow up.

Abstract BACKGROUND: The apparent paradox of natural history data suggesting low rupture risk of small asymptomatic aneurysms and the median size of aneurysm rupture remains unexplained. Aneurysm growth rates and their potential relationship with rupture risk have not been well examined in natural history studies. OBJECTIVE: To examine the question of whether small asymptomatic aneurysms ≤ 7 mm that are followed up over time rupture and to determine the relationship between aneurysm growth and rupture. METHODS: We reviewed all publications on unruptured aneurysms published from 1966 to 2009. We then selected all aneurysms ≤ 7 mm for which measurements were reported for at least 2 time points and for which initial asymptomatic status and ultimate outcome (rupture vs unruptured) were reported. Using the Mann-Whitney U test, we compared absolute diameter annual growth rate. RESULTS: Our search retrieved 64 aneurysms. Thirty aneurysms ruptured during follow-up, of which 27 were enlarged before rupture (90%). Thirty-four aneurysms did not rupture, of which 24 enlarged during follow-up (71%). There was a statistically significant trend toward larger absolute diameter growth for ruptured aneurysms vs unruptured aneurysms (3.89 ± 2.34 vs 1.79 ± 1.02 mm; P &lt; .001), respectively. Annual growth rates for aneurysms for the 2 groups, however, were not statistically different (27.46 ± 18.76 vs 32.00 ± 29.30; P = .92). CONCLUSION: Small aneurysms are prone to growth and rupture. Aneurysm rupture is more likely to occur in aneurysms with larger absolute diameter growth, but rupture can also occur in the absence of growth. The annual growth rate in both groups suggests that rate of growth of aneurysms is highly variable and unpredictable, justifying treatment or close diagnostic follow-up.

Ability To Drive

Background: Studies have questioned the effectiveness of surgery for the management of unruptured intracranial aneurysm (uIA). Few studies have examined the ability to drive and quality of life (QOL) after surgery for uIA. Objective: This study examined the effectiveness of surgical management of uIA by measuring patients’ perceived quality of life and their cognitive abilities related to driving. Methods: Between January 2011 and January 2016 patients with a uIA were assessed using the Quality Metric Short Form 36 (SF36) and the off-road driver screening instrument DriveSafeDriveAware. Reassessments were conducted at the 6-week post-operative follow-up for surgical patients and at 12-month follow-up for surgical and conservatively managed patients. Results: 175 patients enrolled in the study, of which 112(66%) had surgical management of their aneurysm. For the surgical cases who completed all assessments (N=74), there was a trend for the DriveSafe pre-operative mean score of 108 (SD 10.7) to be lower than the 6-week and 12-month post-operative mean scores (111 SD 9.7 and 112 SD 10.2 respectively)(p=0.05). There were no significant changes in DriveAware scores at any epoch or between patient groups nor in the MCS in the surgical group.. There was a significant decline in PCS scores at 6 weeks post-operatively which recovered at 12 months (52 SD 8.1, 46 SD 6.8 and 52 SD 7.1 respectively)( p <0.01). There was no significant difference in 12-month mRS scores between the surgical cases who completed with cases who did not complete all assessments. Conclusion: Surgery for uIA did not affect cognitive abilities for driving at 6 weeks or 12 months after surgery. There was a decline in the QOL in the first months after surgery, however QOL returned to pre-surgical status 12 months after surgery. If the risk of seizures is low and there are no post-operative complications, returning to driving can be recommended.

Background: The recent trend of the treatment of unruptured cerebral aneurysms(UIAs) is going to be conservative. Their natural history of rupture and growth is still unkown. We present the results of annual radiological follow-up study in UIAs. Method: In recent 12 years, we have found 121patients with 148 unruptured cerebral aneurysms were followed annually using 3D-CTA or MRA. Mean follow-up period was 5.5 year. Several factors influencing rupture or growth were statistically examined. Results: Among 121 patients, 9 ruptured and 11 showed growth of UIAs. Annual rupture rate was 1.3% per year and annual growth rate was 1.6% per year. Aneurysm size was the sole factor influencing rupture(P<0.001), whereas female sex and multiplicity were major factors influencing aneurysm growth(P<0.05). Under size 3mm, annual growth rate was 3.0% whereas annual rupture rate was 0.7%. In 4-6mm, growth rate was 1.6% and rupture rate was 1.6%. In 7-9mm, growth rate was 0 and rupture rate was 5.8%. In over 10mm, growth rate was 2.9% and rupture rate was 11.6%. Within 1 year, rupture occurred in 4 cases, and growth was found in 1 case. Conclusions: By annual radiological examination, growth of UIAs was noted more frequently than aneurysm rupture. Especially UIAs under 3mm, growth was 4 times higher than rupture, radiological follow up is effective for aneurysm rupture. Within 1 year, initially found UIAs should be carefully followed in a short interval.

Abstract Background The purpose of this study was to compare the cumulative incidence of postoperative periprosthetic fracture (PPF) in a cohort of femoral neck fracture (FNF) patients treated with two commonly used cemented stems: either a collarless, polished, tapered Exeter stem or the anatomic Lubinus SP2 stem. Methods In this retrospective multicenter cohort study of a consecutive series of patients, we included 2528 patients of age 60 years and above with an FNF who were treated with either hemiarthroplasty or total hip arthroplasty using either a polished tapered Exeter stem or an anatomic Lubinus SP2 stem. The incidence of PPF was assessed at a minimum of 2 years postoperatively. Results The incidence of PPF was assessed at a median follow-up of 47 months postoperatively. Thirty nine patients (1.5%) sustained a PPF at a median of 27 months (range 0–96 months) postoperatively. Two of the operatively treated fractures were Vancouver A (5%), 7 were Vancouver B1 (18%), 10 were Vancouver B2 (26%), 7 were Vancouver B3 (18%), and 13 were Vancouver C (32%). The cumulative incidence of PPF was 2.3% in the Exeter group compared with 0.7% in the SP2 group (p < 0.001). The HR was 5.4 (95% CI 2.4–12.5, p < 0.001), using the SP2 group as the denominator. Conclusions The Exeter stem was associated with a higher risk for PPF than the Lubinus SP2 stem. We suggest that the tapered Exeter stem should be used with caution in the treatment of FNF. Trial registration The study was registered at clinicaltrials.gov (identifier: NCT03326271).

Objective PulseRider is a novel self-expanding nickel-titanium (nitinol) stent for treatment of wide-necked aneurysms, which is commonly located at the arterial branches in the brain. This systematic review and meta-analysis aims to assess the efficacy and safety of PulseRider for treatment of wide-necked intracranial aneurysm. Method We performed a systematic literature search on articles that evaluate the efficacy and safety of PulseRider-assisted coiling of the wide-necked aneurysm from several electronic databases. The primary endpoint was adequate occlusion, defined as Raymond-Roy Class I + Raymond-Roy Class II upon immediate angiography and at six-month follow-up. Results There were a total of 157 subjects from six studies. The rate of adequate occlusion on immediate angiography was 90% (95% CI, 85%–94%) and 91% (95% CI, 85%–96%) at six-month follow-up. Of these, Raymond-Roy Class I can be observed in 48% (95% CI, 41%–56%) of aneurysms immediately after coiling, and 64% (95% CI, 55%–72%) of aneurysms on six-month follow-up. Raymond-Roy Class II was found in 30% (95% CI, 23%–37%) of aneurysms immediately after coiling, and 25% (17–33) after six-month follow-up. Complications occur in 5% (95% CI, 1%–8%) of the patients. There were three intraoperative aneurysm rupture, three thrombus formation, three procedure-related posterior cerebral artery strokes, one vessel dissection, and one delayed device thrombosis. There was no procedure/device-related death. Conclusions PulseRider-assisted coiling for treatment of patients with wide-necked aneurysm reached 90% adequate occlusion rate that rises up to 91% at sixth month with 5% complication rate.
