Özet
AMAÇ: İntrakraniyal anevrizma rüptürü sonrasında yüksek mortalite ve morbidite görülmektedir. Anevrizmanın doğal seyrini anlamak için rüptüre yatkınlık oluşturan faktörleri tanımak önemlidir. YÖNTEM ve GEREÇLER: Analize 2008-2010 arasında 142 ameliyat edilmiş anevrizma (94 kanayan ve 48 rüptür olmamış) dahil edildi. BULGULAR: Anevrizma boynu genişliği ile taşıyan kan damarı - arter çapının arasındaki oran (OR) rüptüre olmuş anevrizmalarda 1,58±0,61 ve rüptüre olmamış anevrizmalarda 1,14±0,52 (p 1,6, OR >1,5 ve inklinasyon açısı >135 derece.
Abstract
AIm: Intracranial aneurysm rupture is followed by high mortality and morbidity. In order to understand the aneurysm’s natural course, it is necessary to recognize the predisposing factors for the rupture. MaterIal and Methods: Analysis included 142 operated aneurysms (94 hemorrhaging and 48 unruptured) in the period from 2008 to 2010. Results: The ratio between the width of the aneurysm neck and diameter of the carrying blood vessel – artery in ruptured aneurysms (OR) was 1.58±0.61, and in unruptured aneurysms 1.14±0.52 (p<0.01). Aspect ratio of ruptured aneurysm was 1.89 ± 0.59, and in unruptured 1:33 ± 0.17. The angle of inclination of ruptured aneurysms was 139.22 ± 21.53, while in unruptured aneurysms it was 101.73 ± 21.26. ConclusIon: Based on the results of our research, a predictive model of morphometric characteristics of the vessel bearing the aneurysm to rupture can be identified: an irregular shape of the aneurysm, AR> 1.6, OR> 1.5 and inclination angle >135 deg.
