To introduce an effective strategy to treat patients with chronic subdural hematoma (CSDH) that can achieve a low recurrence rate and good outcome. ⋯ The exhaustive drainage strategy is safe and effective for reducing recurrence rate and achieving good outcome in patients with CSDH. This procedure merits recommendation in clinical practice.

Stereotactic radiosurgery (SRS) is the reference standard for radiotherapy for pituitary adenomas but has been limited to lesions with sufficient distance (i.e., >3 mm) from the optic apparatus. We used marginless, fractionated (i.e., 25-28 fractions) stereotactic radiotherapy and the CyberKnife to treat pituitary adenomas that were not eligible for SRS. We present the clinical outcomes, including local control, endocrine function, and toxicity from modern fractionated radiotherapy. ⋯ Marginless, fractionated CyberKnife radiotherapy demonstrated excellent local tumor control and endocrine control rates, comparable to those with SRS, with preservation of vision in patients with adenomas in close proximity to the optic pathway.

Based on our clinical experience, posteroinferiorly projecting carotid-A1 junctional aneurysms are often difficult to treat microsurgically. Our objective was to classify peri-internal carotid artery (ICA) bifurcation aneurysms according to their location and analyze their characteristics. ⋯ The characteristics of carotid-A1 junctional aneurysms and true ICA bifurcation aneurysms differ. In particular, carotid-A1 junctional aneurysms tend to have a posteroinferior projection and that causes difficulty in surgical treatment. We recommend the virtual surgical view for preoperative planning. Furthermore, an adequate Sylvian fissure opening and a strategic approach using appropriate devices to inspect blind spots should be considered for a successful treatment outcome.

Removal of the medial wall of the cavernous sinus (MW) is challenging for neurosurgeons. We describe a practical method of endoscopic MW removal via endonasal transsphenoidal approach to minimalize intraoperative blood loss and postoperative morbidities. We also present the pathologic significance of this technique for functional pituitary adenomas (FPAs). ⋯ Occult tumor invasion into the MW was often detected in patients with FPA without a well-defined pseudocapsule but in direct contact with the MW. Our technique can enhance the effectiveness of surgery with minimal postoperative morbidities.

Prospective patient-reported outcomes (PROs) registries are central to emerging evidence-driven reform models. These registries entail significant operator and responder burden to capture PROs data. It is important to limit the number of PROs administered. We sought to determine whether the anxiety/depression domain of EQ-5D could be used to define preoperative psychological distress in patients undergoing elective spine surgery. ⋯ The anxiety/depression domain of EQ-5D could be used to categorize preoperative psychological distress. Spine registries could use this information to potentially limit the number of validated PROs administered.
