Multicenter Study
Genome screen to detect linkage to intracranial aneurysm susceptibility genes: the Familial Intracranial Aneurysm (FIA) study.
Evidence supports a substantial genetic contribution to the risk of intracranial aneurysm (IA). The purpose of this study was to identify chromosomal regions likely to harbor genes that contribute to the risk of IA. ⋯ We have detected possible evidence of linkage to 4 chromosomal regions. There is potential evidence for a gene x smoking interaction with 3 of the loci.

Multicenter Study
Predictors and outcomes of intraprocedural rupture in patients treated for ruptured intracranial aneurysms: the CARAT study.
Intraprocedural rupture (IPR) is a well known complication of intracranial aneurysm treatment. Risks and predictors of IPR and its impact on outcome have not been clearly established. ⋯ IPR was common in patients undergoing treatment of ruptured aneurysms, particularly with surgical clipping. The frequency of IPR with new disability was similar in the surgical and endovascular treatment groups. Coronary artery disease, hyperlipidemia, race, COPD, and lower Hunt and Hess Grade were associated with greater risk of IPR, which may reflect differences in vessel fragility but requires further confirmation.
