This report describes the diagnostic workup of a case of a pseudoaneurysm of the heart resulting from Staphylococcal pericarditis and/or abscesses of the myocardium. The pericardial effusion and myocardial abscesses were detected on 2D echocardiography and computed tomography. The resulting pseudoaneurysm could be demonstrated on magnetic resonance imaging and color Doppler ultrasound, and confirmed by left ventriculography. Color-encoded Doppler ultrasound alone would have provided the definitive diagnosis of the aneurysm.

Color doppler blood flow analysis in circumscribed choroidal hemangioma.
Arq Bras Oftalmol

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.
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.

Background: Testicular torsion (TT) is a urological emergency requiring prompt intervention to prevent irreversible damage to the testicle.
Objective: This study aims to assess trends in men's TT referrals, diagnostic evaluation through Doppler sonography (DS) scan, symptoms before surgery, orchidectomy rates, and TT laterality in relation to age and seasons of the year.
Methods: This observational retrospective cohort study included all patients treated for TT at King Abdullah University Hospital between 2009 and 2021.
Vascular Effects of Botulinum Toxin in Human Skin.

Department of Theoretical Physics, Ruprecht-Karls-University of Heidelberg, Heidelberg, Germany.
Botulinum toxin-A (BTX-A) is widely used for aesthetic purposes and is recognized for its vasomotor actions. However, new medical applications have emerged. This study aims to describe the effect of BTX-A on human skin perfusion, particularly vessel diameter, blood flow, and blood vessel density in regions with known low vessel density.
