Hearing preservation outcomes using direct cranial nerve eight and auditory brainstem response neuromonitoring in the resection of vestibular schwannomas.

Objective: Advancements in microsurgical technique and technology continue to improve outcomes in patients with skull base tumor. The primary cranial nerve eight monitoring systems used in hearing preservation surgery for vestibular schwannomas (VSs) are direct cranial nerve eight monitoring (DCNEM) and auditory brainstem response (ABR), although current guidelines are unable to definitively recommend one over the other due to limited literature on the topic. Thus, further research is needed to determine the utility of DCNEM and ABR.

Stenting for Traumatic Pseudoaneurysms of the Cervical Internal Carotid Artery: Case Report and Systematic Review.

Background: The optimal stenting approach for traumatic pseudoaneurysms (PSA) of the extracranial internal carotid artery (ICA) remains underinvestigated. We present a case of a traumatic pseudoaneurysm of the extracranial ICA managed with stenting and review of prior published similar cases.

Methods: The systematic review followed PRISMA-S guidelines and included studies that investigated traumatic pseudoaneurysms of the extracranial ICA managed by stent placement.

Cerebral arterial vasospasm complicating supratentorial meningioma resection: illustrative cases.

Background: Cerebral arterial vasospasm is a rare complication after supratentorial meningioma resection. The pathophysiology of this condition may be similar to vasospasm after aneurysmal subarachnoid hemorrhage, and treatment options may be similar.

Observations: The authors present two cases of cerebral vasospasm after supratentorial meningioma resection and perform a systematic literature review of similar cases.

Case report and review of literature: Isolated intramedullary spinal neurocysticercosis.

Background: Cases of isolated intramedullary spinal neurocysticercosis are extremely rare. Only 25 cases have been reported before 2022. Due to its rarity, the diagnosis of spinal neurocysticercosis may be missed.

Lower-dose perioperative steroid protocol during endoscopic endonasal pituitary adenoma resection.

Background: Perioperative steroid management for pituitary adenoma resections is multifaceted due to possible hypothalamic-pituitary-adrenal (HPA) axis disruption. Although many different strategies have been proposed, there is no standard protocol for prophylaxis of potential hypocortisolemia.

Methods: We performed a retrospective analysis of consecutive endoscopic endonasal pituitary adenoma resections.

Intra-Arterial Alteplase Thrombolysis during Mechanical Thrombectomy for Acute Ischemic Stroke.

Background: Intra-arterial alteplase (IA tPA) is commonly used during mechanical thrombectomy for acute ischemic stroke in patients with large-vessel occlusion, but specific indications and applications for its use remain undefined.

Methods: We analyzed 40 patients who underwent stent-retriever mechanical thrombectomy, 28 of whom received adjunctive IA tPA. To our knowledge, this is the largest cohort with this concomitant treatment reported in the literature in the post-mechanical thrombectomy trial era.
