Advances in endovascular flow diverters have led to a secular shift in the management of brain aneurysms, causing debate on current bypass indications. We therefore sought to investigate the long-term results, current indications, and trends of bypasses for brain aneurysms. ⋯ Bypass indications have evolved with the inception of novel flow diverters. However, they remain relevant in the cerebrovascular surgeon's armamentarium, and long-term results are excellent.

The role of bypass surgery in intracranial atherosclerotic steno-occlusive diseases (ICADs) remains controversial. We aimed to analyze the surgical outcomes of bypass surgery in patients with the ICADs in a single tertiary institution. ⋯ Low-flow bypass surgery showed acceptable treatment outcomes in the prevention of recurrent stroke.

The optimal surgical management of thoracic schwannomas (TSs) remains contentious, with various approaches proposed. Video-assisted thoracoscopic surgery (VATS) and combined VATS with neurosurgical procedures have shown promise, particularly for Eden type IV and III lesions. However, unanimous consent on the most effective surgical intervention and understanding of prognostic factors for tumor recurrence needs to be improved. The aim of this study was to elucidate the optimal surgical approach according to the Eden type and investigate predictive factors for TS recurrence. ⋯ For Eden type III TSs, neurosurgical and VATS combined surgery achieved better outcomes than neurosurgery alone; for Eden type IV TSs, VATS achieved better results than OT. For Eden types I and II, hemilaminectomy and bilateral laminectomy and laminectomy and TPD achieved similar outcomes, respectively.

Penetrating ballistic cranial trauma (PBCT) carries significant mortality when compared with blunt trauma. The development of coagulopathy in PBCT is a strong predictor of mortality. The goal of the study was to describe the incidence and risk factors of coagulopathy in PBCT and to report the value of tranexamic acid administration in PBCT. ⋯ Coagulopathy is prevalent in approximately 50% of patients with PBCT and is persistent despite treatment in a substantial subset of patients. The addition of thromboelastography with its increased coagulopathy sensitivity can potentially guide treatment more efficiently than traditional coagulopathy laboratory tests and fibrinogen alone. Patients with a significant base deficit on arterial blood gas are at higher risk for coagulopathy.
