The orbital color Doppler echography introduces in imaging arsenal, an information about perfusion of parenchymatous organs and vessels, associated to B-scan sonography. The visualisation of orbital vasculature, has opened a new dimension in ophthalmological US exploration, with applications in normal ocular vasculature evaluation, and also, in regional pathological field: tumor, ocular vascular malformations, carotid-cavernous fistulas, central retinal artery and vein occlusion, ischaemic pathology of the optic nerve, micro/macro diabetic angiopathy, the evaluation of diagnosis and therapy in open-angle glaucoma. Adding the power-angio exploration system, combined with dye injection, may increase the vascular informations in the field of oculo-orbital tumoral pathology. A good knowledge of the anatomy and the pathology, as well as, a high experience in Echo-Doppler examination, are considered as fundamentals in a successful approach of this new exploration method.

Post-craniotomy intracranial pressure monitoring: a novel approach combining optic nerve sheath diameter ultrasonography and cervical-cerebral arterial ultrasound.

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.

A woman in her early 60s presented with multiple transient neurological symptoms over the course of 20 months, including transient loss of power to her right lower limb. Initial workup with CT brain scan, carotid dopplers and ECG revealed no abnormality; however, MRI of the brain suggested recent ischaemic events in separate cortical territories. Subsequent transoesophageal echocardiogram revealed a large mobile mass histologically confirmed to be an atrial myxoma.

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.
Prolonged sitting is not associated with altered shear-mediated dilation of the internal carotid artery, despite impairing lower limb endothelial function.

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 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.
