The Impact

OBJECTIVECerebral aneurysms represent the most common cause of spontaneous subarachnoid hemorrhage. Statins are lipid-lowering agents that may expert multiple pleiotropic vascular protective effects. The authors hypothesized that statin therapy after coil embolization or surgical clipping of cerebral aneurysms might improve clinical outcomes.METHODSThis was a retrospective cohort study using the National Health Insurance Service–National Sample Cohort Database in Korea. Patients who underwent coil embolization or surgical clipping for cerebral aneurysm between 2002 and 2013 were included. Based on prescription claims, the authors calculated the proportion of days covered (PDC) by statins during follow-up as a marker of statin therapy. The primary outcome was a composite of the development of stroke, myocardial infarction, and all-cause death. Multivariate time-dependent Cox regression analyses were performed.RESULTSA total of 1381 patients who underwent coil embolization (n = 542) or surgical clipping (n = 839) of cerebral aneurysms were included in this study. During the mean (± SD) follow-up period of 3.83 ± 3.35 years, 335 (24.3%) patients experienced the primary outcome. Adjustments were performed for sex, age (as a continuous variable), treatment modality, aneurysm rupture status (ruptured or unruptured aneurysm), hypertension, diabetes mellitus, household income level, and prior history of ischemic stroke or intracerebral hemorrhage as time-independent variables and statin therapy during follow-up as a time-dependent variable. Consistent statin therapy (PDC > 80%) was significantly associated with a lower risk of the primary outcome (adjusted hazard ratio 0.34, 95% CI 0.14–0.85).CONCLUSIONSConsistent statin therapy was significantly associated with better prognosis after coil embolization or surgical clipping of cerebral aneurysms.

Computational fluid dynamics (CFD) has grown as a tool to help understand the hemodynamic properties related to the rupture of cerebral aneurysms. Few of these studies deal specifically with aneurysm growth and most only use a single time instance within the aneurysm growth history. The present retrospective study investigated four patient-specific aneurysms, once at initial diagnosis and then at follow-up, to analyze hemodynamic and morphological changes. Aneurysm geometries were segmented via the medical image processing software Mimics. The geometries were meshed and a computational fluid dynamics (CFD) analysis was performed using ANSYS. Results showed that major geometry bulk growth occurred in areas of low wall shear stress (WSS). Wall shape remodeling near neck impingement regions occurred in areas with large gradients of WSS and oscillatory shear index. This study found that growth occurred in areas where low WSS was accompanied by high velocity gradients between the aneurysm wall and large swirling flow structures. A new finding was that all cases showed an increase in kinetic energy from the first time point to the second, and this change in kinetic energy seems correlated to the change in aneurysm volume.

AbstractIntroductionAneurysmal subarachnoid hemorrhage is a type of spontaneous hemorrhagic stroke, which is caused by a ruptured cerebral aneurysm. Cerebral vasospasm (CVS) is the most grievous complication of subarachnoid hemorrhage (SAH). The aim of this study was to examine the risk factors that influence the onset of CVS that develops after endovascular coil embolization of a ruptured aneurysm.Materials and methodsThe study was designed as a cross-sectional study. The patients included in the study were 18 or more years of age, admitted within a period of 24 h of symptom onset, diagnosed and treated at a university medical center in Serbia during a 5-year period.ResultsOur study showed that the maximum recorded international normalized ratio (INR) values in patients who were not receiving anticoagulant therapy and the maximum recorded white blood cells (WBCs) were strongly associated with cerebrovascular spasm, increasing its chances 4.4 and 8.4 times with an increase of each integer of the INR value and 1,000 WBCs, respectively.ConclusionsSAH after the rupture of cerebral aneurysms creates an endocranial inflammatory state whose intensity is probably directly related to the occurrence of vasospasm and its adverse consequences.

Abstract Introduction In Africa, the epidemiology, management, and prognosis of cerebral aneurysms remain poorly understood. Cerebral aneurysms are still highly underdiagnosed and inadequately treated in Africa due to a lack of vascular neurosurgeons and infrastructure. In this review we mapped the burden and management of intracerebral aneurysm in Africa. Methods A full systematic search on articles published in Africa on brain aneurysms was performed in PubMed, African Journals Online, Google Scholar, WHO Global Health Library and LILACS with no language restrictions. The search results were merged, uploaded into Rayyan software, (FDT, USK, IN, NDAB) independently based on the pre-defined inclusion and exclusion criteria. The full text of the remaining articles were then retrieved and screened by three reviewers independently (FDT, USK, NDAB). Conflicts were resolved by mutual agreement. From all included documents, we extracted information regarding study design, socio-demographic characteristics, clinical findings, type of treatment and outcome results. Results We included 28 articles in our full text retrieval. These studies totaled 1181 patients managed for cerebral aneurysm in Africa. Half (50.0%; n = 14) of all studies had been published in the past 5 years and nearly half (46.4%; n = 13) of these studies were conducted in two countries: eight in Morocco and five in South Africa, we didn’t found any publication on cerebral aneurysm for nearly 80% of African countries. Also, there was a female predominance among cerebral aneurysm study participants (62.5%), and the mean time from diagnosis to surgery was 12.1 days. Cerebral aneurysms were most often located in the internal carotid artery (29.6%) and anterior cerebral artery (23.2%). Microneurosurgery (67%) was the most widely used option in these studies ahead of coiling (7.9%). Patient outcomes were judged favorable in 64.2% of cases, and the mortality rate following surgical (open vascular and endovascular) intervention was 19.4%. Conclusion The management of intracerebral aneurysms remains suboptimal in Africa. There are few peer-reviewed reports of aneurysm practice.

Congenital Cyanotic Heart Disease

Noninfectious cerebral aneurysms are rare in patients with congenital cyanotic heart disease. We present a patient with DiGeorge/velocardiofacial syndrome with a complex congenital cyanotic heart disease with a ruptured anterior communicating artery aneurysm. The 10-year-old child was managed by surgical clipping of the aneurysm. Surgical challenges included prominent veins in the Sylvian fissure, difficulty in differentiating arterial and venous bleed, and anesthetic risks. The patient recovered without any neurological deficits. This is the first report of a patient with 22q11.2 deletion syndrome, with a noninfectious cerebral aneurysm.
