Endoscopic endonasal approach for pituitary neuroendocrine tumor with septal mucosa incision tailored to tumor extension intending unilateral septal mucosa preservation.

Currently, the direct endonasal approach is widely used in endoscopic endonasal surgery (EES) for pituitary neuroendocrine tumor. However, a large posterior septal perforation is inevitable. We routinely utilize a modified para/transseptal approach using the combination of a Killian and a contralateral rescue flap incision (PTSA with K-R incision).

Background And Objectives: Direct visualization of the aneurysmal neck and its related perforating arteries during microsurgical clipping of posterior communicating artery (PCoA) aneurysms with posterior projection or true PCoA aneurysms through the pterional approach may be difficult and complicated.
Methods: From January 2022 to January 2023, the clinical and angiographic information regarding PCoA aneurysms were retrospectively collected. Among them, 10 consecutive patients with PCoA aneurysms treated with microsurgical clipping via the subtemporal approach in our single institution were included.

: Postoperative cerebrospinal fluid (CSF) fistulas remain a significant concern in spinal neurosurgery, particularly following dural closure. The incidence of dural tears during spinal surgery is estimated between 1.6% and 10%.

To meet flexible lighting and energy-saving needs, we propose a novel, to the best of our knowledge, dimming control scheme for spectrally efficient clipping-free multilayer optical orthogonal frequency division multiplexing (CFMO-OFDM)-based VLC systems. In order to achieve high dynamic-range dimming control for LEDs, the time-domain CFMO-OFDM signals are first grouped based on frequency-domain subcarrier distribution.

To evaluate the clinical efficacy of modified endoscopic mucosal resection (EMR) in the management of early gastrointestinal lesions. Upon endoscopic identification of the lesion, normal saline is injected into the submucosa to establish a fluid cushion, which elevates the lesion's mucosa. Methylene blue may also be applied to improve visualization of the relationship between the submucosa and muscular layer.
