Impact of hyperoxia and phenylephrine on cerebral oxygenation: An experimental clinical study

Acta Anaesthesiologica Scandinavica, Volume 67, Issue 1, Page 57-65, January 2023., 2023
Abstract Background Oxygen supply to the brain is of special importance during intracranial surgery because it may be compromised by intracranial pathology. A high arterial blood pressure (mean arterial pressure above 80 mmHg) and a high arterial oxygen tension (PaO2 above 12 kPa) is therefore often targeted in these patients, when for example ...

Prognostic Factors for Free Flap Failure in Head and Neck Reconstruction

Head &Neck, EarlyView.
ABSTRACT Background The failure rate of free flaps varies from 0.8% to 10.6% in the literature in head and neck reconstruction. The primary objective was to identify prognostic factors for free flap failure. Methods We prospectively included all consecutive free flaps performed between August 2021 and January 2024, and used a multivariate Cox ...

Learning Wall Segmentation in 3D Vessel Trees using Sparse Annotations [PDF]

We propose a novel approach that uses sparse annotations from clinical studies to train a 3D segmentation of the carotid artery wall. We use a centerline annotation to sample perpendicular cross-sections of the carotid artery and use an adversarial 2D network to segment them.

Open surgical repair for in-stent restenosis of internal carotid artery covered stent-graft

Annals of Vascular Surgery - Brief Reports and Innovations, 2023
Extracranial carotid artery aneurysms (ECAA) are rare vascular anomalies defined as any aneurysmal dilatation of the common, external, or internal carotid artery leading up to the skull base. Operative management is indicated due to the high incidence of

Cadaveric Anatomical Study of Orbit‐Preserving Ophthalmic Neurectomy via Endoscopic and Exoscopic Techniques

Head &Neck, EarlyView.
ABSTRACT Background Perineural spread of cutaneous head and neck squamous cell carcinoma is most effectively managed by surgical resection with a clear central margin at the affected nerve. For ophthalmic nerve disease, there is no clear consensus regarding the extent of spread which is resectable via an orbit‐preserving neurectomy, either in regard to

Carotid Artery Plaque Analysis in 3D Based on Distance Encoding in Mesh Representations [PDF]

arXiv
Purpose: Enabling a comprehensive and robust assessment of carotid artery plaques in 3D through extraction and visualization of quantitative plaque parameters. These parameters have potential applications in stroke risk analysis, evaluation of therapy effectiveness, and plaque progression prediction.

Three‐Dimensional Evaluation of Superficial Temporal Artery and Its Terminal Branches: Implications for Clinical Practice

Head &Neck, EarlyView.
ABSTRACT Background The superficial temporal artery (STA) and its terminal branches are crucial in various clinical procedures, including reconstructive surgeries and aesthetic interventions. Understanding the depth and course of these arteries is essential to minimize complications during such procedures.

Moderate hyperuricaemia ameliorated kidney damage in a low‐renin model of experimental renal insufficiency

Basic &Clinical Pharmacology &Toxicology, Volume 132, Issue 1, Page 21-32, January 2023., 2023
Abstract Uric acid has promoted renal fibrosis and inflammation in experimental studies, but some studies have shown nephroprotective effects due to alleviated oxidative stress. We studied the influence of experimental hyperuricaemia in surgically 5/6 nephrectomized rats. Three weeks after subtotal nephrectomy or sham operation, the rats were allocated

Bilateral Thyroid Ima Arteries Arising From the Brachiocephalic Trunk: A First Case Report

Head &Neck, EarlyView.
ABSTRACT Rationale Bilateral thyroid ima artery (TIA) arising from the brachiocephalic trunk is an extremely rare anatomical variation, with no prior cases reported. Recognizing such vascular anomalies is crucial for optimizing surgical outcomes in thyroid and mediastinal procedures, as failure to identify these variations can lead to severe ...

Targeting the interaction of GABAB receptors with CaMKII with an interfering peptide restores receptor expression after cerebral ischemia and inhibits progressive neuronal death in mouse brain cells and slices

Brain Pathology, Volume 33, Issue 1, January 2023., 2023
There is no pharmacological treatment available to limit progressing neuronal death after cerebral ischemia. Here we show that targeting the interaction of GABAB receptors with CaMKII using a synthetic interfering peptide after an excitotoxic insult in cultured neurons or in brain slices from MCAO‐treated mice restored downregulated GABAB receptor ...
