“…One of the main challenges in modern neurosurgery is determining the stage of aneurysm for the subsequent estimating of the risks of its rupture. The data of various mechanical experiments show significantly different results depending on the method of transportation of the samples, the sensitivity of the used tensile machine and the method of the experiment [3][4][5][6][7]. It was shown [8] that the difference in the mechanical properties of aneurysms among representatives and between samples with different experimental techniques can be comparable.…”

In practical neurosurgery, an important issue is determining the status of the aneurysm and predicting its further growth, rupture or stabilization. The main approaches for the study of risk analysis asessment are computational hydrodynamics and analysis of the mechanics of the wall of cerebral aneurysm. In this paper, an analysis of various sections of the wall of cerebral aneurysm is given, combining mechanical test data and histological examination data. It was shown that, along with significant diﬀerences in mechanics, a diﬀerent degree of calcification is observed in the tissue, which indicates a diﬀerent level of impaired transport of substances inside the tissue.

“…Its results should allow to perform surgery in the most effective way or avoid it if possible. Such parameters could be determined using different methods, such as strength tests [ 2 ], histological studies [ 3 ]. In the meantime, nondestructive methods are preferable.…”

Background: Cerebral aneurysms (CA) are a widespread vascular disease affecting 50 per 1000 population. The study of the influence of histological, morphological and hemodynamic factors on the status of the aneurysm has been the subject of many works. However, an accurate and generally accepted relationship has not yet been identified. Methods: In our work, the results of mechanical and spectroscopic measurements are considered. Total investigated 14 patients and 36 their samples of CA tissue. Results: The excitation–emission matrix of each specimen was evaluated, after which the strength characteristics of the samples were investigated. Conclusions: It has been shown that there is a statistically significant difference in the size of the peaks of two components, which characterizes the status of the aneurysms. In addition, a linear regression model has been built that describes the correlation of the magnitude of the ultimate strain and stress with the magnitude of the peaks of one of the components. The results of this study will serve as a basis for the non-invasive determination of the strength characteristics of the cerebral tissue aneurysms and determination of their status.
