Objective: Elevated intracranial pressure (ICP), a common complication in traumatic brain injuries (TBI), can lead to optic nerve sheath diameter (ONSD) enlargement and flow spectrum changes from the internal carotid artery (ICA) to middle cerebral artery (MCA). This study will investigate the use of Cervical-Cerebral Arterial Ultrasound (CCAU) for non-invasive ICP assessment and evaluating the related indices' clinical utility in TBI patients with decompressive craniotomy (DC).

Methods: ONSD and flow spectrum changes were measured within 24 h after DC in 106 patients via ultrasonic ONSD measurement and CCAU, simultaneously.

Color doppler blood flow analysis in circumscribed choroidal hemangioma.

Arq Bras Oftalmol

January 2025

Department of Ophthalmology & Visual Sciences, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.

Purpose: To evaluate if color Doppler can detect internal blood flow in circumscribed choroidal hemangioma.

Methods: This cross-sectional study examined seven eyes of seven participants with circumscribed choroidal hemangiomas, with or without prior treatment. B-scan ultrasound and color Doppler were used to assess the dimensions, topographical distribution, and internal blood flow of the affected eyes.

The present study aims to examine the effect of 4 h of continuous sitting on cerebral endothelial function, which is a crucial component of cerebral blood flow regulation. We hypothesized that 4 h of sitting may impair cerebral endothelial function similarly to how it affects lower limb vasculature. Thirteen young, healthy participants were instructed to remain seated for 4 h without moving their lower limbs.

Optimizing the life of vascular access during follow-up.

J Cardiovasc Surg (Torino)

February 2025

Department of Vascular Surgery, ASST Settelaghi Universitary Teaching Hospital, University of Insubria, Varese, Italy.

Optimizing the longevity of vascular access in hemodialysis patients remains a critical aspect of patient care, given the significant role of arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs) in enabling effective dialysis. Vascular access complications, such as stenosis, thrombosis, and cannulation-related damage, continue to challenge both the functionality and the sustainability of these access points. Recent advancements underscore the importance of a robust follow-up strategy, integrating clinical evaluations with diagnostic tools like color Doppler ultrasound (CDU) and emerging interventional approaches such as drug-coated balloon (DCB) angioplasty.
