Abstract:
Marfan syndrome is a relatively common connective tissue disorder that causes skin, ocular, skeletal, and cardiovascular abnormalities. High morbidity and mortality occur with aortic aneurysm and dissection. Other large-artery aneurysms, including carotid, subclavian, and iliac artery aneurysms, have also been associated with Marfan syndrome. It is not clear whether small- to medium-sized artery aneurysms are associated with Marfan syndrome. This report describes 4 patients with Marfan syndrome who have associated small- to medium-sized artery aneurysms with several complications. Additional investigations are needed to determine whether Marfan syndrome can cause small- to medium-sized artery aneurysms and how patients with these aneurysms should be treated.
Insights
Marfan syndrome, a connective tissue disorder, is linked to large artery aneurysms. This study explores its potential association with small- to medium-sized artery aneurysms, requiring further investigation.
Area of Science:
- Vascular Medicine
- Genetics
- Connective Tissue Disorders
Background:
- Marfan syndrome is a genetic disorder affecting connective tissue, primarily known for cardiovascular complications like aortic aneurysm and dissection.
- While Marfan syndrome is associated with large artery aneurysms, its link to small- to medium-sized artery aneurysms remains unclear.
Observation:
- This report details four patients diagnosed with Marfan syndrome who also presented with small- to medium-sized artery aneurysms.
- These patients experienced several complications related to these aneurysms.
Findings:
- The study highlights a potential, yet unconfirmed, association between Marfan syndrome and the development of small- to medium-sized artery aneurysms.
- Complications arising from these aneurysms in Marfan syndrome patients were observed.
Implications:
- Further research is crucial to establish a causal link between Marfan syndrome and small- to medium-sized artery aneurysms.
- Investigating optimal treatment strategies for patients with both Marfan syndrome and small- to medium-sized artery aneurysms is necessary.

Overview of Systemic Arteries
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the heart.
