Mural repair following obliteration of aneurysms: II. Pathomorphology of treated aneurysms

Mural vascular repair following experimental and clinical aneurysm obliteration was studied using the scanning electron microscope and standard histological techniques. Two of the more frequently utilized clinical obliteration techniques, clipping and coagulation, were examined. A chronological description of the mural reparative process reveals that clipping is superior to coagulation in most instances, that coagulation results in satisfactory obliteration of the aneurysmal orifice only in very selected circumstances, and that a combination of coagulation and clipping may be the best overall obliteration technique.
