Abstract

Rupture of an intracranial aneurysm (IA) leads to a rare subtype of intracranial bleeding, i. e., subarachnoid hemorrhage (SAH). However, SAH is associated with high long-term morbidity and mortality. Risk factors for the development and rupture of IA include modifiable factors, i. e., smoking and arterial hypertension. Symptoms of obstructive sleep apnea (OSA) are commonly reported following the rupture of an IA. The purpose of this review is to summarize the currently available evidence on the prevalence and effect of OSA in patients with IA. With an exploratory intent, we further identified potential mechanisms by which OSA might promote the development, growth, and rupture of IA.

Besteht ein kausaler Zusammenhang zwischen obstruktiver Schlafapnoe und der Pathophysiologie intrakanieller Aneurysmen?

Zusammenfassung

Die Ruptur eines intrakraniellen Aneurysmas (IA) kann zu einem seltenen Subtyp einer intrakraniellen Blutung, d. h. zu einer Subarachnoidalblutung (SAB), führen. Dabei geht eine SAB mit einer hohen Langzeitmorbidität und -mortalität einher. Zu den Risikofaktoren für die Entstehung und Ruptur eines IA gehören modifizierbare Faktoren wie Rauchen und arterielle Hypertonie. Häufig wird nach der Ruptur eines IA über Symptome einer obstruktiven Schlafapnoe (OSA) berichtet. Ziel der vorliegenden Übersichtsarbeit ist es, eine Zusammenfassung der derzeit verfügbaren Evidenz zur Prävalenz und zu den Auswirkungen einer OSA bei Patienten mit IA zu geben. Um dies näher zu untersuchen, ermittelten die Autoren potenzielle Mechanismen, durch welche eine OSA die Entstehung, das Wachstum und die Ruptur eines IA begünstigen könnte.
