Modeling of Saccular Aneurysm Growth in a Human Middle Cerebral Artery

Journal of Biomechanical Engineering, 2008
Saccular aneurysm growth in a human middle cerebral artery is modeled. The aneurysm growth model was presented in a companion paper by Kroon and Holzapfel ("A Model for Saccular Cerebral Aneurysm Growth by Collagen Fibre Remodelling," J. Theor. Biol., in

A Mathematical Model for the Mechanics of Saccular Aneurysms

Neurosurgery, 1985
We constructed and discussed a mathematical model of intracranial saccular aneurysms based on the static mechanics of hollow vessels and were able to focus on three variables that are fundamental to the process of enlargement and rupture of these lesions.

Saccular aneurysm of infancy and early childhood

Neurosurgery, 1978
Abstract A case of intracranial saccular aneurysm occurring in early childhood and presenting with sudden dysphasia and hemiplegia is reported. A review of the literature emphasizes the rarity of this lesion. Despite a significant preoperative neurological deficit, the patient tolerated ancurysm clipping and recovered well.

An Unusual Saccular Aneurysm

New England Journal of Medicine, 2002
Figure 1. A 49-year-old woman underwent a diagnostic workup for recurrent headaches. Computed tomography suggested the presence of an incidental aneurysm of the left internal carotid artery. This finding was confirmed by cerebral angiography, which demonstrated an unusual, heart-shaped saccular aneurysm originating from the ventral aspect of the ...

Origin, Growth, and Rupture of Saccular Aneurysms

Neurosurgery, 1981
Pathological and hemodynamic concepts regarding the origin, growth, and rupture of intracranial saccular aneurysms are reviewed. Aneurysms form as a result of an interplay between hemodynamic factors, such as axial stream impingement and the water hammer effect, and structural weaknesses at apices of arterial bifurcations, such as congenital and ...

Experimental saccular aneurysms

Neuroradiology, 1994
A new technique for surgical construction of experimental lateral saccular aneurysms on the common carotid artery of swine is described. It involves end-to-side suturing of an isolated segment of vein to an artery. During a short period of parent artery clamping, an elliptical arteriotomy is fashioned through the open-ended vein graft, the open end of ...

Saccular Arterial Aneurysm

2018
Saccular arterial aneurysms (SAA) are the space-occupying lesions that can occur in both suprasellar and in parasellar areas. Giant aneurysms located there have clinical manifestations identical to the tumors. Differential diagnosis should be made from tumors of the chiasmal-sellar region.

Enlargement of intracranial saccular aneurysms

Acta Neurochirurgica, 1980
A case of enlargement of a middle cerebral artery aneurysm is reported. Cerebral angiography demonstrated an increase in the size of this aneurysm. Possible factors causing aneurysmal enlargement are discussed.

Intracranial Saccular Aneurysms

2003
It has long been accepted that mechanical factors play a critical role in the natural history of intracranial saccular aneurysms — their pathogenesis, enlargement, and rupture. Nevertheless, until very recently, biomechanical analysis has been surprisingly scant. In this chapter, we see how nonlinear elasticity, membrane theory, nonlinear dynamics, and

Multiple Saccular Aneurysms

Abstract This chapter presents a 74-year-old woman with a complex neurological history, including a previous stroke, who now exhibits right arm shaking and a subarachnoid hemorrhage from a ruptured anterior communicating saccular aneurysm.
