Aim: The purpose of this study is to compare the pressure differences between the aneurysm sac and the parent artery in both ruptured and unruptured aneurysms to investigate the effect of pressure differences on the aneurysm rupture. Material and methods: Patients treated for ruptured and unruptured aneurysms were included in the study. All the cases were imaged using catheter angiography and the aneurysms were filled with coils. The measurement was made just before and after the microcatheter was advanced into the aneurysm. The aneurysm's height-width, maximum dome diameter, neck diameter and entrance angle were measured in three-dimensional images. Results: Endovascular treatment of 40 aneurysms was performed. Of these aneurysms, 17 (42.5%) were unruptured; 23 (57.5%) were ruptured. There was no statistically significant difference between patient groups with ruptured and unruptured aneurysms in terms of the demographic data and risk factors, the perioperative pressure measurements in the aneurysm sac and parent artery and the aneurysm morphological measurement. Conclusion: In our study, peroperative pressure measurements in the aneurysm sac and parent artery were similar in both ruptured and unruptured aneurysms, and no statistically significant difference was found in any result between the groups. A wider series of studies about aneurysm's characteristics such as shape or wall properties will contribute to our knowledge to clarify the mechanisms that play a role in the formation, growth and rupture of intracranial aneurysms.
