Abstract

SUMMARY


Background and purpose: Excluding completely intracranial aneurysms (IAs) from cerebral circulation is the goal of surgical
and endovascular treatment. The choice of methodology as well as the planning of the treatment is influenced by characteristics of
the IAs. Digital Subtraction Angiography (DSA) is the gold standard for evaluating this condition. We describe the characteristics of
ruptured IA (RIAs) by DSA and find the correlation between the characteristics of RIA with the clinical state of the patients.
Materials and methods: The descriptions of 237 patients definitely diagnosed with RIA by DSA at Cho Ray Hospital from June 2012 to February 2013 were reviewed for this study.
Results: Most of patients were hospitalized with Hunt – Hess from I to III (74.3%). 94.5% of RIAs were from the internal carotid. Small and medium size RIAs were 97%, only 1.3 % were the giant aneurysm. RIAs of the small neck size were 88.5%. According to Ratio of sac to neck size (RSN), the narrow and medium neck sizes were 88.4%. 97.5% of RIAs had an uneven edge. The relationship to the major neighboring artery from RIA was 6.8%.
The aplitic A1 segment at the opposite side for ACA of RIAs was 48.8%. Cerebral vasospasm after SAH was 28.3%. No correlation was found between location, RIA size or neck size and the clinical state of the patients. However, a definite correlation was found between cerebral vasospasm and the clinical state of the patients (Fisher test, p< .001).
Conclusion: Knowledge gained about the characteristics of RIAs by DSA is useful in order to choose methodology of the treatment as well as planning the technical treatment effectively.
