[Marfan's syndrome. Aortic complications studied by scanography]
Abstract:
Of all the pathological forms and variations of Marfan's syndrome, aortic aneurysm is one of the most important because of the high risk of medial dissection caused by cystic necrosis. The value of computerised axial tomography in the diagnosis of the aortic lesions of Marfan's syndrome was assessed in three clinical cases. Compared to angiography and echocardiography, computerised tomography avoids arterial catheterisation while demonstrating all anatomical changes of the aorta, coronary arteries, pericardium and mediastinum, with significantly less radiation. The point of entry of the dissection was not visualised in two of the cases presented. Therefore, computerised axial tomography should be considered in patients with Marfan's syndrome.
Insights
Computerised axial tomography aids in diagnosing aortic aneurysms in Marfan syndrome patients. This imaging technique offers a comprehensive view of the aorta and surrounding structures with reduced radiation exposure.
Area of Science:
- Cardiovascular Imaging
- Medical Diagnostics
- Genetics and Rare Diseases
Background:
- Marfan syndrome is a genetic disorder affecting connective tissue, with aortic aneurysm and dissection posing significant risks.
- Aortic complications, including cystic medial necrosis leading to dissection, are a primary cause of morbidity and mortality in Marfan syndrome.
- Accurate diagnosis of aortic lesions is crucial for timely intervention and improved patient outcomes.
Observation:
- This study evaluated the utility of computerised axial tomography (CAT) in diagnosing aortic lesions in three Marfan syndrome patients.
- CAT imaging was compared against traditional methods like angiography and echocardiography.
- The assessment focused on the ability of CAT to visualize anatomical changes in the aorta, coronary arteries, pericardium, and mediastinum.
Findings:
- Computerised axial tomography effectively visualizes aortic anatomical changes in Marfan syndrome, including aneurysms and related structures.
- CAT avoids invasive arterial catheterization required for angiography and delivers significantly less radiation compared to other imaging modalities.
- While CAT provides a comprehensive overview, the precise point of dissection entry was not visualized in two of the presented cases.
Implications:
- Computerised axial tomography is a valuable, non-invasive diagnostic tool for assessing aortic complications in Marfan syndrome.
- The findings suggest CAT should be considered as a primary or adjunctive imaging modality for Marfan syndrome patients with suspected aortic disease.
- Further research may explore optimizing CAT protocols to enhance visualization of dissection entry points in Marfan syndrome patients.
