Insights
Coronary endarterectomy, a procedure during bypass surgery, involves removing plaque. Histology reveals the separation plane is consistently within the artery
Area of Science:
- Cardiovascular Surgery
- Vascular Histology
- Surgical Pathology
Background:
- Coronary artery bypass grafting (CABG) is a common procedure for coronary artery disease.
- Coronary endarterectomy is sometimes performed concurrently with CABG to remove atherosclerotic plaque.
- The precise histological plane of dissection during endarterectomy has been a subject of discussion.
Abstract:
Described herein is a patient who had a coronary endarterectomy at the time of coronary artery bypass grafting. Histologic study of cross-sections of the endarterectomy specimen disclosed that the layer of separation of the endarterectomy specimen from the underlying native artery was in the media. This layer or plane of excision is virtually always the media irrespective of the artery having the endarterectomy. The procedure might better be called "endomediaectomy?"
