For years, diabetic retinopathy has been defined based on vascular lesions, and neural abnormalities were not regarded as important. This review summarizes evidence that the neural retina has important effects on the retinal vasculature under normal conditions, and the interaction between the retinal neuroglial cells and vascular function is altered in diabetes. Importantly, new evidence raises...

Although vascular abnormalities are thought to affect coronavirus disease 2019 (COVID-19) patients’ outcomes, they have not been thoroughly characterized in large series of unselected patients. The Swiss national registry coronavirus-associated (CAVA) is a multicentric cohort patients with severe acute respiratory syndrome 2 (SARS-CoV-2) infection who underwent clinically indicated chest comput...

OBJECTIVE To compare resting long axis echocardiography with adenosine thallium-201 emission tomography in detecting myocardial ischaemic abnormalities in patients before peripheral vascular surgery. DESIGN A prospective and blinded preoperative examination of resting left ventricular minor and long axes and myocardial perfusion during adenosine vasodilatation using thallium-201 emission tomo...

Endothelial progenitor cells (EPCs) enter the systemic circulation in response to cues related to vascular damage and need for neovascularization. Thus, EPCs could become readily accessible informers of vascular status and enable the survey of vascular pathologies during preclinical stages. To identify EPC changes with biomarker potential, we investigated whether discrete EPC abnormalities were...

Esophageal varices and hematemesis in severe cases can lead to significant morbidity mortality without correct treatment. be brought on by a variety of causes, including infection, vascular abnormalities, inflammatory illnesses, trauma, cancer. Its location, severity, causes all influence how it is diagnosed, managed, treated. The field radiology especially interventional offers quick, efficien...

OBJECTIVE To evaluate umbilical cord abnormalities predisposing to mechanical cord compression and determine their relationship to adverse clinical outcomes and stasis-associated histologic changes in the placenta. METHODS Placental slides of 224 singleton pregnancies with gross cord abnormality (true knots, long cords, nuchal/body cords, abnormal cord insertion, hypercoiled cords, narrow cor...

The brain MR images of 23 patients with angiographically proved moyamoya disease were reviewed to evaluate the capability of MR to demonstrate vascular and parenchymal abnormalities. All the MR images were obtained on a 2.0 T superconducting system and included T1-weighted sagittal and T2-weighted axial images without implementation of flow compensation (FC). The vascular abnormalities demonstr...

Post-partum haemorrhage is a major determinant of maternal mortality. Traditionally, cases of post-partum haemorrhage caused by arterial injuries were managed by caesarean hysterectomies or bilateral internal iliac artery ligations. The diagnosis of aneurysms or arteriovenous malformations of uterine artery are often missed. Uterine curettage, caesarean section or vaginal delivery can result in...

Williams syndrome (WS) is a developmental disorder characterized by vascular abnormalities such as thickening of the vascular media layer in medium- and large-sized arteries. Supravalvular aortic stenosis (SVAS) and peripheral pulmonary artery stenosis (PPAS) are common vascular abnormalities in WS. The natural course of SVAS and PPAS is variable, and the timing of surgery or intervention is de...

Thirty men who presented with erectile impotence to the urological department underwent a thorough urological, angiological, and neurological examination with complementary neurophysiological tests of somatosensory and sympathetic and parasympathetic function. Most had vascular and neurological abnormalities. Clinical findings and electrophysiological tests for autonomic dysfunction had the hig...
