Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Impact of Valsalva manuever on choroidal vascularity index, central choroid and central macula

Photodiagnosis and Photodynamic Therapy, 2023
Evaluation of the effects of the Valsalva maneuver on choroidal vascularity index, central choroid and the central macula.Eighty-four eyes of 42 healthy volunteers were evaluated in this prospective study. The central macular layer was assesed using the retinal map mode of the spectral domain OCT (Optovue RTVue XR, Optovue Inc., Fremont, CA), OCT ...

Choroidal vascular hyperpermeability patterns in central serous chorioretinopathy correlate with microperimetry: CERTAIN study report 4

Acta Ophthalmologica, EarlyView.
Abstract Purpose This report evaluates the association of three distinct leakage patterns of choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA), previously correlated with disease chronicity, with retinal sensitivity measured by microperimetry in central serous chorioretinopathy (CSC): unifocal indistinct signs of ...

Pregnancy as a risk factor for central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Purpose Pregnancy induces significant changes in the body, including increased peripheral and choroidal blood perfusion and an increased systemic corticosteroid level. Here, we systematically reviewed the evidence on pregnancy as a risk factor for developing central serous chorioretinopathy (CSC) and conducted a meta‐analysis to obtain a ...
