Permanent closure of the ductus arteriosus require loss of cells from the muscle media and development of neointimal mounds, composed in part of proliferating endothelial cells.

The subject of my analysis is arterial intimal hyperplasia.

A cornerstone question lies behind all approaches to the disease: what causes the pathology. I argue that the question itself is misplaced because it implies that intimal hyperplasia is a novel pathological phenomenon caused by   Obesity is the main risk factor for hypertension in children and adolescents.
