Abstract
Background
Quantitative data on the impact of smoking on genesis of intracranial aneurysms (IA) is sparse. We aimed to analyze the association between lifetime and current smoking exposure and IA characteristics.
Methods
In this prospective observational cohort study (07/2016–01/2023, n = 918), all patients or next of kin filled out the questionnaire for assessment of smoking habits including the status (no/former/current) and consumption level (heavy vs light current smoker [≥/<10 cigarettes/day], and lifetime exposure in pack-years). The study endpoints were the ruptured status, size, and presence of multiple IA.
Results
The distribution of non-, former, light, and heavy smokers was 23.2 %, 25.6 %, 11.2 % and 40 % respectively. The median lifetime smoking exposure was 20 pack-years. Current smokers were at higher risk of presenting with ruptured (adjusted odds ratio [aOR]=1.71, 95 % confidence interval [CI]=1.29–2.26, p < 0.0001), large (≥7 mm, aOR=1.41, 95 % CI=1.05–1.89, p = 0.022) and multiple IA (aOR=1.34, 95 % CI=1.01–1.77, p = 0.045). In the subgroup analysis among ever smokers, heavy smoking additionally increased the risk of IA rupture (aOR=1.83, 95 % CI=1.33–2.50, p < 0.0001) and larger size (aOR=1.65, 95 % CI=1.19–2.30, p = 0.003). Finally, longer history of smoking (>20 pack-years) was related to higher probability of multiple (aOR=1.61, 95 % CI=1.21–2.13, p = 0.001) and large IA (aOR=1.40, 95 % CI=1.04–1.87, p = 0.025).
Conclusions
Our data underline the role of smoking in IA genesis, and the importance of smoking cessation for rupture prevention. Current and particularly heavy smoking increases the risk of IA rupture, whereas the chronic exposure over years more likely results in the development of multiple and large IA.
