Abstract [eng] Background / objective The present prospective study was undertaken to assess the reliability of the aspect ratio (i.e. aneurysm deph to aneurysm neck width) for predicting aneurysm rupture. Unruptured aneurysm, ruptured aneurysm and rebleeded aneurysm patient groups are compared. Aneurysm size, site, patient age and gender also are taken into account. Patients and methods Intraoperative measurements were made of consecutive patients with 265 aneurysms in three patient groups admitted between 2000 and 2006 to Department of Neurosurgery, Vilnius University Emergency Hospital. 23 unruptured aneurysms, 206 ruptured and 36 which rebled where included into the study. Giant and fusiform aneurysms were excuded from the study. Results Aspect ratio was 1.83 ± 0.2 (p < 0.01) for unruptured aneurysms, 2.36 ± 0.05 (p < 0.01) for ruptured and 3.1 ± 0.08 (p < 0.01) which rebled. Aneurysm size has not to be found significant factor for aneurysm rupture in our study. Aneurysm neck was wider on high flow arteries (i.g., MCA and ICA) to compare with low flow arteries (i.g., ACom and PCom) respectively 3.45 ± 0.17 mm and 3.01 ± 0.07 mm (p < 0.05). Conclusion The aspect ratio was found to be a statistically significant important index to calculate for predicting aneurysm rupture.
