Endovascular therapy for cerebrovascular disease is widespread. Patients with brain aneurysms, acute stroke, brain vascular malformations, and tumors are treated with endovascular techniques primarily or in conjunction with other traditional surgical and medical approaches. Postprocedural concerns unique to endovascular treatment include complications related to access or arterial puncture, contrast nephrotoxicity, and radiation dose complications (eg, alopecia and skin burns). Other complications, such as stroke and hemorrhage, that are not unique are discussed below.

Background and Objectives: Intracranial hemorrhage caused by the rupture of brain aneurysms occurs in almost 10 per 100,000 people whereas the incidence of such aneurysms is significantly higher, accounting for 4–9%.Linking certain factors to cerebral aneurysm rupture could help in explaining the significantly lower incidence of their rupture compared to their presence. The aim of this study is to determine the association between the corresponding circle of Willis configurations and rupture of cerebral aneurysms. Materials and Methods: A group of 114 patients treated operatively for aruptured cerebral aneurysm and a group of 56 autopsied subjects were involved in the study. Four basic types of the circle of Willis configurations were formed—two symmetric types A and C, and two asymmetric types B and D. Results: A statistically significantly higher presence of asymmetry of the circle of Willis was determined in the group of surgically-treated subjects (p = 0.001),witha significant presence of asymmetric Type B in this group (p < 0.001). The changeson the A1 segment in the group of surgically-treated subjects showed a statistically significant presence compared to the group of autopsied subjects (p = 0.001). Analyzing the presence of symmetry of the circle of Willis between the two groups, that is, the total presence of symmetric types A and C, indicated their statistically significant presence in the group of autopsied patients (p < 0.001). Conclusions: Changes such as hypoplasia or aplasia of A1 and the resulting asymmetry of the circle of Willis directly affect the possibility of the rupture of cerebral aneurysms. Detection of the corresponding types of the circle of Willis after diagnostic examination can be the basis for the development of a protocol for monitoring such patients.

Wall Imaging

High-resolution vessel wall imaging (HR-VWI) is becoming a useful tool in the characterization and identification of unstable unruptured brain aneurysms. However, it has not been validated for clinical use. The current evidence on HR-VWI techniques for characterization of brain aneurysms is described in this review. Specific imaging approaches such as aneurysm wall contrast enhancement, MRI-quantitative susceptibility mapping, and 7T MRI are described in detail.

The wall of saccular brain aneurysms, lesions that develop at the fork regions of human brain arteries, is a layered multidirectional fabric of fibrous collagen. The wall tissue has the mechanical features of high elastic stiffness and a low tensile strength compared to adjacent arteries. Arterial blood pressure within the sac of an aneurysm stresses the wall in all tangential directions; thus an area of mechanical weakness may be characterized by an area lacking fibre strength, or an area with inadequately aligned fibres.The collagen fibres of the wall are birefringent, with many fibre types, similar to wound healing skin (types I, III, IV, V, VI) The known correlation between fibre birefringence and tissue strength for dermal wound healing3 provided the opportunity in this research to calculate strength maps to compare one lesion from another, and to make regional comparisons around a single lesion.
