This study aimed to investigate the hemodynamic changes induced by a flow diverter (FD) and coils in the treatment of internal carotid artery aneurysms, as well as to evaluate the effect of this treatment by using angiographic follow-up data. ⋯ On the basis of using the CFD method, adjunctive coiling with the Tubridge FD placement may significantly reduce intra-aneurysmal flow velocity and WSS, promoting thrombosis formation and occlusion of aneurysms.

In neurosurgical procedures, avoiding damage of surrounding tissues such as muscle and periosteum during a craniotomy is important for esthetic and other reasons. We devised a protection tool by using an amputated syringe barrel to cover the perforating drill and protect temporal muscle damage. This device made it possible to prevent damage to surrounding tissues, such as the muscle and periosteum, during cranial perforation. This method could be useful as it is cost-effective, simple, and versatile.

Frailty is an emerging means of assessing overall health status and guiding management for geriatric patients. Frailty is associated with outcomes for many surgical indications in this age group. While half of all glioblastoma patients are 65 years old or older, frailty has not been examined in relation to surgery for glioblastoma. ⋯ Frailer patients with glioblastoma receive less aggressive intervention, have longer hospital stays, and experience more complications. Frailty may be an underused metric for the preoperative risk assessment of geriatric glioblastoma patients.

Tuberculum sellae meningiomas (TSM) arise from the dura mater of tuberculum sellae, limbus sphenoidale, and chiasmatic sulcus and cause asymmetric visual disturbances. In this study, we analyzed the laterality of the origin of TSM and discussed its clinical implications on immediate and long-term visual outcomes. ⋯ Most TSMs that originated from the dura of one lateral end portion of the tuberculum sellae correlated with asymmetric visual symptoms and poor visual outcomes. This microsurgical feature should be considered in the planning of optimal surgical strategy to achieve favorable outcomes.

To study the rate of superficial temporal artery (STA) preservation and the effectiveness of STA reconstruction in patients undergoing a pterional craniotomy. ⋯ Preserving or reconstructing of the STA during pterional craniotomy is feasible in the majority of the patients with very high rate of anastomosis patency. STA hinders elevation of the skin/muscle flap in approximately 38% of the pterional approaches and without reconstruction afterwards, the STA would been occluded.
