The rupture of an anterior communicating artery aneurysm does not associate with an asymmetry in the A1 or A2 arteries: a retrospective study of radiological features.

BACKGROUND AND OBJECTIVES: Although the formation and rupture risk of an anterior communicating artery (ACoA) aneurysm has been the subject of many studies, no previous study has primarily searched for the relationship of the parent and daughter vessels and the impact of their size/diameter ratio on the potential rupture risk of an AcoA aneurysm. The objective of this study is to explore this link and to further analyse the surrounding vasculature of the anterior communicating artery aneurysm. MATERIALS AND METHODS: We conducted a retrospective analysis of 434 patients: 284 patients with an ACoA aneurysm (121 unruptured and 162 ruptured) and 150 control patients without an ΑCoA aneurysm. Radiological angiography investigations were used to assess the diameter ratios of the parent vessels in addition to ACoA aneurysm morphology parameters. RESULTS: When comparing the ruptured to the unruptured cases, we observed no significant difference in the parent or daughter vessel diameter ratios. Younger patient age (OR 0.96, p = 0.00) and a higher aneurysm size ratio (OR 1.10, p = 0.02) were of prognostic importance concerning the rupture risk of the aneurysm. The A1 diameter ratio and the A2 diameter were not statistically significant (OR 1.00, p = 0.99, and OR 3.38, p = 0.25 respectively). CONCLUSIONS: In our study, we focused on asymmetry in the parent and daughter vessels as well as traditional ACoA aneurysm morphological characteristics. We were able to label younger patient age and a greater size ratio as independent prognostic factors for ACoA aneurysm rupture. We were unable to label parent and daughter vessel asymmetry as prognostic factors. To validate our findings, parent and daughter vessel asymmetry should be subjected to future prospective studies.

[Psychoeducation for Relatives of Persons with Depressive Disorders: A Focus Group Study on Information Demands]. / Psychoedukative Gruppen für Angehörige von depressiv Erkrankten: Analyse des Informationsbedarfs durch eine Fokusgruppenuntersuchung.

BACKGROUND: Depressive disorders place a high burden on patients and their relatives. Psychoeducational groups for relatives may reduce relatives' burden and improve the course of disease in patients. To foster the development of psychoeducational interventions which meet relatives' needs, information demands in relatives of patients with depressive disorders were examined. METHODS: A qualitative study using 3 focus groups was conducted among adult relatives of patients with depressive disorders (N=17). Discussions were audio-taped, transcribed and analyzed using qualitative content analysis. RESULTS: Information demands are based on information gaps, emotional burden as well as strains in everyday living and were identified with regard to illness-specific (symptoms, course and etiology), treatment-specific (treatment options and health care system) and - as central aspects - interaction-specific issues (dealing with the patient, difficulties in everyday living and relationship problems) as well as support options for relatives themselves and self-care. CONCLUSIONS: Information brokerage within psychoeducational groups for relatives should consider the burden of relatives as well as strains in everyday living on which information demands are based. To consider interaction-specific issues, specific skills - e. g. in problemsolving - should be trained.
