Healing of the canine aorta after endarterectomy: a scanning electron microscopy study. 1974

H S Moseley, and R S Connell, and W W Krippaehne

Endarterectomy sections of canine aorta were examined in various stages of healing by scanning electron microscopy. In all specimens the endarterectomy site was quickly covered by a thin fibrin-platelet coagulum with varying amounts of thrombus. Neoendothelization began before one week and was virtually completed by one month except on areas of heavy thrombus deposition. While this study does not prove the origin of the neoendothelial cell, it suggests that neoendothelial cells are derived from pre-existing endothelium and advance over the endarterectomy site from the junction zone of the normal aorta and to a lesser extent from the orifices of brancing vessels.

D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D004691	Endarterectomy	Surgical excision, performed under general anesthesia, of the atheromatous tunica intima of an artery. When reconstruction of an artery is performed as an endovascular procedure through a catheter, it is called ATHERECTOMY.	Thromboendarterectomy,Endarterectomies,Thromboendarterectomies
D004727	Endothelium	A layer of epithelium that lines the heart, blood vessels (ENDOTHELIUM, VASCULAR), lymph vessels (ENDOTHELIUM, LYMPHATIC), and the serous cavities of the body.	Endotheliums
D005337	Fibrin	A protein derived from FIBRINOGEN in the presence of THROMBIN, which forms part of the blood clot.	Antithrombin I
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
