Dual versus single Antiplatelet Therapy in Carotid Artery Endarterectomy: Direct Comparison of Complications Related to Antiplatelet Therapy.
Dual and single antiplatelet therapies are routinely used in carotid artery endarterectomy (CEA). However, the efficacy and safety of these therapies are controversial. The present study aimed to comprehensively compare the clinical outcomes between dual and single antiplatelet therapies in CEA. ⋯ Based on current evidence, using single antiplatelet therapy in CEA may reduce operation time and the incidences of 30-day death, neck hematoma, major bleeding, and myocardial infarction without increasing the risks of transient ischemic attack, stroke, or a longer operation time.

Cerebral edema is a major cause of morbidity in patients with severe traumatic brain injury (TBI). Intraparenchymal thermal conductivity-based probes that measure local cerebral blood flow can measure percent brain tissue water (%BTW) content, but such measures have been insufficiently characterized in patients with TBI. ⋯ %BTW may be a clinically useful, real-time measurement of cerebral edema in patients with TBI. It is closely associated with the serum sodium concentration and follows a characteristic temporal course with characteristic trajectory and stability over time.

Coil protrusion occasionally occurs during embolization and can lead to thromboembolic complications. We aimed to evaluate the efficacy of rescue stenting procedures with a low-profile stent system (LVIS Jr.) for treating ruptured intracranial aneurysms during complicated coil embolization. ⋯ Our findings indicate that LVIS Jr. stent rescue therapy is clinically useful for handling coil protrusion during the embolization of ruptured intracranial aneurysms.

The natural history of colloid cysts is imperfectly understood, and controversies remain in defining broad management strategies for incidental colloid cysts. The gradual asymptomatic regression of a colloid cyst has not been reported. ⋯ Gradual regression of a colloid cyst is possible. The philosophical and practical implications of this case on the neurosurgeon's approach to managing patients with colloid cysts are discussed.

Comparison of conventional microscopic and exoscopic experimental bypass anastomosis - A technical analysis.
Recently, the use of digital exoscopes has been increasingly promoted as an alternative to microscopes. The aim of this study is to compare experimental bypass quality in both visualization methods. ⋯ Both methods produced equally satisfactory results in experimental bypass procedures. The exoscope has the potential for better 3-dimensional visualization and sharing the surgeon's view with others for teaching purposes.
