“…3,4,13,16,17,22,26,34,38,40 More specifically, neck width, dome width, aneurysm shape, aspect ratio (height/neck width), and bottleneck factor (dome width/neck width) have been examined. Among these, aspect ratio has shown the greatest promise as a parameter to associate with rupture risk (Fig.…”

Aneurysmal subarachnoid hemorrhage continues to have high rates of morbidity and mortality for patients despite optimal medical and surgical management. Due to the fact that aneurysmal rupture can be such a catastrophic event, preventive treatment is desirable for high-risk lesions. Given the variability of the literature evaluating unruptured aneurysms regarding basic patient population, clinical practice, and aneurysm characteristics studied, such as size, location, aspect ratio, relationship to the surrounding vasculature, and the aneurysm hemodynamics, a metaanalysis is nearly impossible to perform. This review will instead focus on the various anatomical and morphological characteristics of aneurysms reported in the literature with an attempt to draw broad inferences and serve to highlight pressing questions for the future in our continued effort to improve clinical management of unruptured intracranial aneurysms.

“…3,4,16,19,26,33,40,41 Consistently, ruptured aneurysms are larger than unruptured aneurysms. Typical results have demonstrated the mean size of unruptured aneurysms to be between 4 and 6 mm, and mean size of ruptured aneurysms is between 5 and 8 mm, which is statistically significant.…”

“…AR value <1.5 was found in ruptured aneurysms in only 10.59%, while with unruptured it was found in 80.64%. A slightly higher percentage of ruptured aneurysms with a value were found by Beck in almost 21% (2). AR> 1.6 has a high predisposition to rupture (28,32).…”

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. 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. soNUÇ: Araştırmamızın sonuçları temelinde rüptüre olacak anevrizmayı taşıyan damarın morfometrik özelliklerinin prediktif bir modeli tanımlanabilir: Anevrizmada düzensiz şekil, aspekt oranı >1,6, OR >1,5 ve inklinasyon açısı >135 derece.

Cerebral Vascular Tree Matching of 3D-RA Data Based on Tree Edit Distance

Abstract. In this paper, we present a novel approach to matching cerebral vascular trees obtained from 3D-RA data-sets based on minimization of tree edit distance. Our approach is fully automatic which requires zero human intervention. Tree edit distance is a term used in the field of theoretical computer science to describe the similarity between two labeled trees. In our approach, we abstract the geometry and morphology of vessel branches into the labels of tree nodes and then use combinatorial optimization strategies to compute the approximated edit distance between the trees. Once the optimal tree edit distance is computed, the spatial correspondences between the vessels can be established. By visual inspection to the experimental results, we find that our approach is accurate.
