Human embryotoxicity of pyrrolizidine‐containing drugs
Ryan J. Huxtable – 1 March 1989 – Hepatic veno‐occlusive disease is the most frequent cause of hepatic vein obstruction in children. Only the small and medium veins are involved. The initial vascular lesion is endothelial edema, followed by phlebosclerosis and occlusion of the small vessels, leading to secondary necrosis of liver cells, progressive fibrosis, and ultimately cirrhosis. The disease was first recognized in Jamaica in 1954, and subsequently reported from other parts of the world.
