OBJECTIVES Ruptured anterior communicating artery (ACoA) aneurysms occur more frequently in men. The purpose of the study was to investigate sex difference in aneurysm morphologies and clinical outcomes in patients with ruptured ACoA aneurysms. SETTING A tertiary referral hospital. PARTICIPANTS A total of 574 consecutive patients with ACoA aneurysms were admitted to our hospital from Decemb...

BACKGROUND AND PURPOSE FD technology enables reconstructive repair of otherwise difficult-to-treat intracranial aneurysms. These stentlike devices may induce progressive aneurysm thrombosis without additional implants and may initiate complete reverse vessel remodeling. The associated vascular biologic processes are as yet only partially understood. MATERIALS AND METHODS From 12 different cen...

Arterial bifurcations in the circle of Willis were observed three-dimensionally in 44 cases of cerebral aneurysm and 45 control cases. Variations of the circle of Willis were also studied in relation to cerebral aneurysm. The following results were obtained : 1. Aneurysm always occurred at the apex of the cerebral arterial bifurcation where axial flow in the parent artery immediately proximal t...

BACKGROUND AND PURPOSE Elastase-induced aneurysms in rabbits have become an accepted model to study endovascular treatment. The size and shape of the resulting aneurysms may vary widely. Our goal was to predict the final aneurysm morphology on the basis of immediate postinduction geometry. METHODS Thirty New Zealand white rabbits were used. Aneurysms were created at the origin of the right co...

BACKGROUND Risk prediction of rupture of intracranial aneurysms is poor and is based mainly on lumen characteristics. However, characteristics of the aneurysm wall may be more informative predictors. The limited resolution of currently available imaging techniques and the thin aneurysm wall make imaging of wall thickness challenging. OBJECTIVE To introduce a novel protocol for imaging wall th...

This study investigates the effect of a novel flow remodeling stent graft (FRSG) on the hemodynamic characteristics in highly angulated abdominal aortic aneurysm based on computational fluid dynamics (CFD) approach. An idealized aortic aneurysm with varying aortic neck angulations was constructed and CFD simulations were performed on nonstented models and stented models with FRSG. The influence...

Bypass surgery is often used in the treatment of large and giant aneurysms. Major complications that often arise during the perioperative period include cranial nerve palsy, ischemic complications, and hyperperfusion. However, there have been a few reports about late onset complications such as anastomotic aneurysms. In particular, anastomotic aneurysm after high flow bypasses has never been re...

OBJECTIVE Elevated plasma aldosterone concentrations in patients have been linked to a spectrum of cardiovascular diseases. Mineralocorticoid receptor antagonists provide additional benefits in patients with heart failure. However, whether aldosterone and the mineralocorticoid receptor are involved in aortic aneurysm is unknown. APPROACH AND RESULTS We report that administration of deoxycorti...

A 21-year-old woman presented with an unruptured large intracavernous aneurysm, which was spontaneously revascularized via unusual collateral pathways a short time after extracranial-intracranial bypass and surgical ligation of the proximal internal carotid artery. The patient had been treated for a large basilar trunk aneurysm with intraaneurysmal embolization using Guglielmi detachable coils,...

BACKGROUND AND PURPOSE There are, to our knowledge, no histologic data correlating aneurysm volume with histologic healing following coil embolization of aneurysms. We report a retrospective study comparing histologic outcome with aneurysm volume in elastase-induced aneurysms in rabbits. MATERIALS AND METHODS Aneurysm volume and histologic healing after coil embolization were retrospectively ...
