The features of cerebral aneurysms hemodynamics
Abstract
Objective: to study the hemodynamic features in intracranial aneurysms. Material and methods: we performed 4D CT-angiography at 3 patients with unruptured aneurysms of various localization and size. Results: The aneurysm contrast was observed in arterial, venous and delayed phases after contrast injection. We noted the repeated contrast of aneurismal sac in venous phase (on 27-29 sec from contrast injection) in each of three presented clinical cases. Conclusion: The noted feature of aneurysm contrast (repeated contrast in venous phase) is much more likely related to so-called “theory of slow blood flow” which is one of the modern theories for explanation of aneurysm occurrence and their growth. However the further investigation is necessary to confirm this suggestion.
