Familial occurrence of abdominal aortic aneurysms
Surgery
|June 1, 1984
Summary
Familial aggregation of abdominal aortic aneurysms (AAA) was observed in 1.9% of siblings and cousins of patients. This suggests a potential genetic predisposition to developing this serious vascular condition.
Area of Science:
- Vascular Surgery
- Medical Genetics
- Epidemiology
Background:
- Abdominal aortic aneurysms (AAAs) are a significant cause of mortality.
- Understanding the familial occurrence of AAAs is crucial for risk stratification.
Purpose of the Study:
- To investigate the familial aggregation of clinically diagnosed and ruptured abdominal aortic aneurysms (AAAs).
- To assess the potential genetic predisposition to AAA development.
Main Methods:
- Retrospective study of 200 consecutive AAA patients treated between 1965-1981.
- Standardized questionnaires sent to 89 surviving patients; 87 responded.
- Analysis of family pedigrees for AAA occurrence.
Main Results:
- Familial AAA occurred in 14 families among living patients.
- 1.9% of siblings and 3.4% of deceased siblings died from ruptured AAAs.
- At least 11 deceased patients had a family history of AAA.
Conclusions:
- Evidence suggests familial aggregation of abdominal aortic aneurysms.
- A genetic predisposition to AAA development may exist.
- Further research into genetic factors influencing AAA is warranted.
