Article Synopsis
- Failure to retrieve a distal filter-based embolic protection device (EPD) during carotid artery stenting can occur if the device gets trapped, requiring careful monitoring of the space between the stent and EPD.* -
- The study tested different combinations of stents and EPDs to see how often they got stuck, with four physicians rating the force needed for entrapment on a 5-point scale.* -
- The Casper stent-Spider FX EPD was found to be particularly difficult to disengage if trapped, highlighting the importance of understanding device features to avoid serious complications.*
Background: Older patients are increasingly presenting for surgery with intracranial meningioma because of progress with diagnostic imaging and longer life expectancy. However, older patients have many problems, such as comorbidities and reduced physiological capacity reflected in the frailty index. This study examines the factors affecting clinical deterioration after surgery in older patients, particularly factors associated with frailty.

A 61-year-old man presented with sudden onset headache. Initial computed tomography revealed SAH around the brainstem.

- Reports on surgical methods via the trans-lamina terminalis and trans-third ventricle are limited, with unknown associated risks.
- After an unsuccessful endovascular surgery on a 78-year-old woman with a ruptured basilar tip aneurysm, direct surgical clipping was performed through the third ventricle.
- The patient experienced transient hypothermia potentially linked to hypothalamic dysfunction, highlighting the need to understand the risk of hypothermia following these surgical approaches despite unclear mechanisms of hypothalamic thermoregulation.
We describe a rare case of cavernous angioma in the dura mater and discuss published MRI findings on similar cases. The patient was a 78-year-old woman who was referred to Shimane Prefectural Central Hospital with complaints of headaches. We were subsequently able to identify a tumor at the convexity in the dura mater.
