Influence of nonalcoholic fatty liver disease severity on carotid adventitial vasa vasorum.

Introduction: Nonalcoholic fatty liver disease (NAFLD) affects a quarter of the world's population and encompasses a spectrum of liver conditions, from non-alcoholic steatohepatitis (NASH) to inflammation and fibrosis. In addition, NAFLD also links to extrahepatic conditions like diabetes or obesity. However, it remains unclear if NAFLD independently correlates with the onset and progression of atherosclerosis.

Influence of Morbid Obesity and Bariatric Surgery Impact on the Carotid Adventitial Vasa Vasorum Signal.

Introduction/purpose: Adventitial vasa vasorum (VV) expansion to the avascular intima precedes an increase in carotid intima-media thickness. However, factors involved in the development of the atherosclerotic process and its reversibility remain unclear. We aimed to evaluate the VV signal in both morbid obesity and after bariatric surgery (BS).
