Prompt diagnosis and therapy of aneurysms are critical for patients with nontraumatic subarachnoid hemorrhage (SAH). The aim of our study was to assess the clinical usefulness of multislice computed tomography angiography (CTA) in the surgical and endovascular treatment of intracranial aneurysms. A total of 195 cases with 206 intracranial aneurysms underwent CTA. Fifty (24%) aneurysms underwent...

case presentation a 27-year-old male, without a remarkable medical history, who suffered from abdominal pain for 2 days after falling was admitted to the emergency department with hypovolemic shock. upon performing emergency laparotomy a ruptured splenic artery aneurysm was found. conclusions it is important to consider rupture of a splenic artery aneurysm in patients with abdominal pain and hy...

BACKGROUND AND PURPOSE Pediatric aneurysms are rare and, thus, relatively poorly understood as compared to those in adults. Our aim was to characterize the clinical, imaging, treatment, and outcome data of patients younger than 19 years diagnosed with intracranial aneurysms at a tertiary care institution. MATERIALS AND METHODS We performed a retrospective medical record review of pediatric pa...

BACKGROUND AND PURPOSE Patients with intracranial aneurysms are at risk for future development of new aneurysms and growth of additional untreated aneurysms. Because in previous long-term studies duration of follow-up varied widely, the time interval after which screening could be effective remains largely unknown. The purpose of this study was to assess the incidence of de novo aneurysm format...

This was a proof-of-concept computational fluid dynamics (CFD) study designed to identify atherosclerotic changes in intracranial aneurysms. We selected 3 patients with multiple unruptured aneurysms including at least one with atherosclerotic changes and investigated whether an image-based CFD study could provide useful information for discriminating the atherosclerotic aneurysms. Patient-speci...

BACKGROUND AND PURPOSE Rates of development of de novo intracranial aneurysms and of growth of untreated additional aneurysms are largely unknown. We performed MRA in a large patient cohort with coiled aneurysms at 5-year follow-up. METHODS In 276 patients with coiled intracranial aneurysms and 5±0.5 years of follow-up MRA (totaling 1332 follow-up patient-years), additional aneurysms were cla...

Background and Aim: This study aimed at analyzing the demographic characteristics of the patients with non-traumatic intracranial hemorrhage, their angiographic results and the correlation between computed tomography (CT) scan and angiography findings. Methods and Materials/Patients: In a descriptive study, we retrospectively reviewed the records of the patients with non-traumatic intracranial...

OBJECTIVE Although surgical techniques for clipping paraclinoid aneurysms have evolved significantly in recent times, direct microsurgical clipping of large and giant paraclinoid aneurysms remains a formidable surgical challenge. We review here our surgical experiences in direct surgical clipping of large and giant paraclinoid aneurysms, especially in dealing with anterior clinoidectomy, distal...

BACKGROUND AND PURPOSE Patients with a history of aneurysmal subarachnoid hemorrhage may have aneurysms on screening several years after the hemorrhage. For determining the benefits of follow-up screening, it is important to know whether these aneurysms have developed after the hemorrhage or are visible in retrospect, and if so, whether the size has increased. METHODS Aneurysms were categoriz...

AIm: To discuss the surgical methods for multiple intracranial aneurysms. mATeRIAL and meTHods: 23 patients were divided into three groups according to the location of the aneurysms: aneurysms located in one side or in the midline of the Willis ring; aneurysms located on both sides of the Willis ring with unruptured aneurysms located ahead of the middle cerebral artery bifurcation; and MIAs loc...
