Summary
Genetic factors likely contribute significantly to abdominal aortic aneurysm (AAA) development. Screening siblings of affected individuals, especially smokers, may be beneficial for early detection of this vascular disease.
Area of Science:
- Vascular Surgery
- Genetics
- Epidemiology
Background:
- Abdominal aortic aneurysm (AAA) is a serious vascular condition with potential genetic links.
- Understanding the inheritance patterns of AAA is crucial for risk assessment and prevention.
Purpose of the Study:
- To investigate the genetic predisposition to abdominal aortic aneurysm (AAA).
- To determine the familial occurrence and potential inheritance patterns of AAA.
Main Methods:
- Family history was collected from 60 consecutive patients undergoing aneurysm repair.
- The prevalence of AAA in first-degree relatives and siblings was calculated.
Main Results:
- Twenty patients (33%) reported a first-degree relative with AAA.
- 8% of first-degree relatives and 7% of siblings had AAA.
- Positive family history was associated with younger age at presentation and higher prevalence in women.
Conclusions:
- Abdominal aortic aneurysm (AAA) likely has a multifactorial inheritance pattern, with a significant genetic component (approx. 70%).
- Screening siblings of affected individuals, particularly smokers in female and younger male probands, may be warranted for early detection.
