Classification and hemodynamic characteristics of delayed intracerebral hemorrhage following stent-assisted coil embolism in unruptured intracranial aneurysms.

Background And Objective: Stent-assisted coil (SAC) embolization is a commonly used endovascular treatment for unruptured intracranial aneurysms (UIAs) but can be associated with symptomatic delayed intracerebral hemorrhage (DICH). Our study aimed to investigate the hemodynamic risk factors contributing to DICH following SAC embolization and to establish a classification for DICH predicated on hemodynamic profiles.

Methods: This retrospective study included patients with UIAs located in the internal carotid artery (ICA) treated with SAC embolization at our institution from January 2021 to January 2022.

Surgical Technique and Efficacy Analysis of Extra-pseudocapsular Transnasal Transsphenoidal Surgery for Pituitary Microprolactinoma.

Objective: To elucidate the role of transsphenoidal surgery in the treatment of pituitary microprolactinoma.

Methods: The clinical data of 107 prolactinoma cases treated by extra-pseudocapsular transnasal transsphenoidal surgery (ETTS) for different indications in our department since 2011 was retrospectively analyzed.

Results: The most common indication was the ineffectiveness of oral medication (41.

Overview of the 2022 WHO Classification of Pituitary Adenomas/Pituitary Neuroendocrine Tumors: Clinical Practices, Controversies, and Perspectives.

The latest edition of the WHO classification of the central nervous system was published in 2021. This review summarizes the major revisions to the classification of anterior pituitary tumors. The most important revision involves preferring the terminology of pituitary neuroendocrine tumor (PitNET), even though the terminology of pituitary adenoma (PA) still can be used according to this WHO classification compared to the previous one.

Cavernous Malformations: Updates in Surgical Management and Biology.

Cavernous malformations (CMs) are low-flow vascular lesions of the central nervous system prone to symptomatic hemorrhage. CMs are estimated to be present in approximately 0.5% of the population.

Loss of programmed cell death 10 activates tumor cells and leads to temozolomide-resistance in glioblastoma.

Purpose: Glioblastoma (GBM) is one of the most aggressive and incurable primary brain tumors. Identification of novel therapeutic targets is an urgent priority. Programmed cell death 10 (PDCD10), a ubiquitously expressed apoptotic protein, has shown a dual function in different types of cancers and in chemo-resistance.

Intraoperative neuromonitoring for removal of large vestibular schwannoma: Facial nerve outcome and predictive factors.

Background: Preservation of facial nerve (FN) function is one of the major goals for resection of large vestibular schwannoma (VS) (≥ 30 mm). Little is known about the FN outcome and its predictive factors due to limited data.

Objective: To explore the predictive factors affecting FN outcome following resection of large VS.
