The management of cavernous carotid aneurysms (CCAs) poses a significant dilemma to the treating surgeon. Asymptomatic CCAs usually are managed conservatively with clinical and radiologic follow-up. Large size, intradural extension, sphenoid bone erosion, and increasing size on follow-up are usual indications for treating asymptomatic CCAs. However, there are no clear-cut guidelines in literature. We share our experience of 40 asymptomatic CCAs treated by endovascular and surgical methods. ⋯ The current study demonstrates excellent outcomes of asymptomatic CCAs after treatment. In view of the technical advancements of both surgical and endovascular methods, consideration for treatment should be given to asymptomatic CCAs. Each aneurysm should be individually assessed by experts for choosing the best endovascular or surgical treatment option.

Flat back deformity is a disabling adverse outcome following instrumented lumbar fusion. As patients are often fused in this non-physiologic alignment, correction is complex and has conventionally required fracture of the preexisting fusion mass. Sacral osteotomy may be one effective means of correcting the positive sagittal balance in these patients. Here we report a case of flat back deformity corrected using a 3-column sacral osteotomy, and systematically review the available literature on the effectiveness of 3-column sacral osteotomy for correcting flat back deformity. ⋯ Sacral osteotomy is potentially an effective means of correcting positive sagittal balance in patients with flat back deformity secondary to high pelvic incidence.

Patients with hematologic disorders who present with subdural hematomas (SDH) present a surgical decision-making challenge. Because of intrinsic coagulopathy, platelet dysfunction, and immunosuppression, surgical intervention poses a unique set of risks. ⋯ Low platelet and hemoglobin levels are consistent markers of poor prognosis and surgical intervention, either as a proxy of or as a cause for clinical deterioration, is associated with increased mortality risk.

Few studies have addressed the causes of poor expansion of the spinal canal after open-door laminoplasty (ODL) that require revision surgery. The aim of this study is to identify the reasons of poor expansion of the spinal canal after ODL and to discuss the surgical methods and clinical outcomes of the posterior revision surgery. ⋯ The main causes of poor expansion of the spinal canal after ODL were inadequate expansion degree of the spinal canal and improper expanded range of the spinal canal. Posterior revision surgeries, such as ODL, LCF, and laminectomy of responsible lamina, could guarantee fine clinical results.

To identify predictors of atherosclerotic change in aneurysms and parent arteries, and to retrospectively analyze outcomes from clipped aneurysms that showed atherosclerotic changes. ⋯ FRS, diabetes mellitus, and aneurysm size as predictors of atherosclerosis in patients undergoing aneurysm surgery can help guide surgical decisions and performance.
