Structural changes in abdominal aorta and vena cava inferior after experimental microwave destruction.

摘要

We studied morphological changes in rat abdominal aorta and vena cava inferior induced by endovascular microwave destruction. This treatment induced thrombosis and necrosis of the vascular walls, but fibrous framework was not completely destroyed. Then we observed irreversible changes in vessels: obliteration, atrophy of the aorta walls, and sclerosis of venous walls. The preserved fibrous framework of the vessel walls probably plays a role of a framework for the formation of fibrous tissue.
