Color doppler blood flow analysis in circumscribed choroidal hemangioma.

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.

Department of Angiology, University Hospital Zurich, University of Zurich, Switzerland.
Background: In patients with post-thrombotic syndrome (PTS), stent recanalization of iliofemoral veins or the inferior vena cava can restore venous patency and improve functional outcomes. The risk of stent thrombosis is particularly increased during the first 6 months after intervention. The ARIVA trial tested whether daily aspirin 100 mg plus rivaroxaban 20 mg is superior to rivaroxaban 20 mg alone to prevent stent thrombosis within 6 months after stent placement for PTS.

Aim: The current investigation aimed to evaluate the accuracy of ultrasonography and color Doppler performed in the diagnosis of intraosseous jaw lesions.
Materials And Methods: A total of 30 patients with intraosseous jaw lesions between the ages of 12 and 60 were selected for the present study. For every jaw lesion, a preliminary diagnosis was done using preoperative conventional radiographs.
