Chronic coronary periarteritis in two patients with chronic periaortitis
Insights
Chronic coronary periarteritis and chronic periaortitis can be linked. These cases suggest a unifying concept for chronic periaortitis, potentially caused by hypersensitivity to atheroma.
Area of Science:
- Cardiovascular Pathology
- Immunology
Background:
- Chronic periaortitis encompasses various fibrotic conditions affecting the aorta and surrounding structures.
- Idiopathic retroperitoneal fibrosis and inflammatory aneurysms are recognized manifestations.
Observation:
- Two cases detail chronic coronary periarteritis co-occurring with chronic periaortitis.
- One case presented perianeurysmal fibrosis around a thoracic aortic aneurysm.
- The second case showed features similar to idiopathic retroperitoneal fibrosis.
Findings:
- The observations support a unified concept of chronic periaortitis.
- This concept integrates previously distinct conditions like idiopathic retroperitoneal/mediastinal fibrosis and inflammatory aortic aneurysms.
- The findings are consistent with a hypersensitivity reaction to atheroma as a potential cause.
Implications:
- This research may lead to a better understanding and classification of fibrotic aortic diseases.
- It suggests a potential autoimmune or hypersensitivity mechanism underlying these conditions.
- Further research into atheroma-related hypersensitivity could reveal new diagnostic and therapeutic targets.
Abstract:
Two cases of chronic coronary periarteritis associated with chronic periaortitis are described. In one, the chronic periaortitis took the form of perianeurysmal fibrosis around a thoracic atherosclerotic aneurysm; in the other it resembled idiopathic retroperitoneal fibrosis. The findings in the two subjects support the unifying concept of chronic periaortitis, to include conditions previously known as idiopathic retroperitoneal or mediastinal fibrosis, perianeurysmal retroperitoneal fibrosis and inflammatory aneurysms of the aorta. The observations are also compatible with the view that the disease is due to hypersensitivity to atheroma.
