Early angiographic changes after carotid endarterectomy.
This report reviews the angiographic evaluation of 41 patients who underwent a carotid endarterectomy at Henry Ford Hospital. Postoperative angiograms were performed after 48 endarterectomies. Changes included the development of postoperative intimal flaps, common carotid stenosis, carotid occlusions, areas of corrugation, surface irregularities, and postendarterectomy dilatation. The development of dilatation, or the pantaloon effect, on the endarterectomized segment contributed to the limited use of angioplastic procedures. The benefits derived from a postoperative angiogram include the objective evaluation of the endarterectomized segment, the demonstration of a potentially complicating problem such as intimal flaps that could lead to restenosis, and recognition of the possible development of associated local problems. The procedure can be done with limited risks to the patients and in competent hands has low morbidity and mortality.
