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. ⋯ 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.

In this study, we evaluated the difference in incidence of symptomatic vasospasm between ruptured aneurysms in the anterior and posterior circulation using multiple logistic regression analysis. ⋯ Although a poor clinical grade and a severe SAH classification on admission such as Hunt and Hess grade and Fisher's classification are established powerful predictors of symptomatic vasospasm, ruptured vertebrobasilar aneurysm are for the first time reported to be a predictor of symptomatic vasospasm based on results of a recent reliable statistical analysis.

Few randomized clinical trials (RCTs) in the field of traumatic brain injury (TBI) have shown a significant treatment benefit. We critically reviewed the use of two types of secondary analyses, covariate adjustment and subgroup analysis, which are common in TBI trials. ⋯ The reported covariate adjustment and subgroup analyses from TBI trials had several methodological shortcomings. Appropriate performance and reporting of covariate adjustment and subgroup analysis should be considerably improved in future TBI trials because interpretation of treatment benefits may be misleading otherwise.

Review Case Reports
Aneurysmal rupture during coiling: low incidence and good outcomes at a single large volume center.
To study the incidence and clinical outcomes of intraoperative aneurysm rupture (IOR) during endovascular coil embolization at a single large volume center and to review the literature on this subject to determine whether IOR rupture rate and mortality correlate with volume of aneurysms treated at a given center and years since the institution of Guglielmi detachable coils as a treatment modality. ⋯ IOR remains a serious risk of endosaccular coiling of intracranial aneurysms, with aneurysms presenting with subarachnoid hemorrhage at greater risk for this complication. This risk can be minimized with very low associated morbidity and mortality (incidence 1%, 17% morbidity, 0% mortality at our institution).

Case Reports Multicenter Study
Balloon-in-stent technique for the constructive endovascular treatment of "ultra-wide necked" circumferential aneurysms.
Circumferential aneurysms, which incorporate >180 degrees of the circumference of the parent vessel, present a unique therapeutic challenge, particularly in circumstances in which a deconstructive treatment strategy is not feasible. We detail a novel technique for endovascular parent vessel reconstruction with aneurysm embolization. ⋯ The balloon-in-stent technique provides a practical and safe treatment strategy for the management of circumferential aneurysms that are not amenable to deconstructive embolization.
