Primary prevention

One-quarter of patients with autosomal dominant polycystic kidney disease (ADPKD) have aneurysms at autopsy, and 2% to 8% of patients with aneurysms have ADPKD.[36] Individuals with ADPKD are potential candidates for aneurysm screening.[29]

Because of the possible hereditary aspects of SAH, patients who have two or more first-degree relatives with SAH are potential candidates for aneurysm screening.[25][29][35]​​

Hypertension should be corrected, as this is one of the most important modifiable risk factors.[26][29][30]​​[31][32][33][34]

Smoking is another important modifiable risk factor.[26][30][31][32][33][34] All patients should be encouraged not to smoke.
