This is the first report of success in numerically quantifying and visualizing cardiac cycle-related intracranial vessel motion and pulse waves in human subjects by using 320-detector CTA and a newly developed motion-detection algorithm to better understand the physiologies of intracranial arteries. This new technique promises to provide significant novel information for analyzing the elasticit...

For broad-based intracranial aneurysms, both surgical and endovascular treatments are demanding. Flexible metallic stents provide an alternative treatment option for these patients, because they enable coil placement through the stent mesh. Evidence from extracranial arteries indicates that aneurysms may also spontaneously thrombose after stent placement. This case report documents three patien...

BACKGROUND AND PURPOSE The purpose of this study was to determine if postmortem intracranial arteries from donors with HIV without stroke have thinner media layers compared with patients without HIV and without stroke. METHODS Cross-sectional cuts from intracranial arteries were stained with van Gieson and hematoxylin and eosin. Arteries were examined for thickness of each arterial layer. Uni...

Low (LDL) and very low (VLDL) density lipoproteins retained in grossly normal and atherosclerotic human intracranial arteries have been quantitated using an electro-immunoassay directed against apolipoprotein B (apoB), the major protein of these two lipoprotein fractions. Buffer-homogenates of grossly normal arteries contained apoB amounts ranging from less than 0.04 to 1.58 microng/mg tissue d...

Dolichoectasis is a dilative arteriopathy that can be seen in intracranial vertebral and basilar arteries people with hypertension advanced age. Although most cases are asymptomatic, cerebral ischemia, bleeding or compression may occur. The diagnosis of VBD was made by catheter angiography before; while MR the sensitive imaging method today. In addition, differential aneurysm/other vascular pro...

A 5-year-old boy was referred to our hospital for evaluation of headache, tortuous intracranial arteries and vertebral arteries found up on brain magnetic resonance angiography. The patient’s family history was unremarkable for any genetic disease. He was born at 39 weeks of gestation by spontaneous vaginal delivery without complications. His birth weight was 3,580 gm. At 3 years Neurovascular ...

BACKGROUND As a systemic disease, atherosclerosis commonly affects intracranial and extracranial carotid arteries simultaneously which is defined as co-existing plaques. Previous studies demonstrated that co-existing atherosclerotic diseases are significantly associated with ischemic cerebrovascular events. The aim of this study was to investigate the characteristics of co-existing intracranial...

Bacterial endocarditis may give rise to mycotic arterial aneurysms in any part of the body, but particularly in the thoracic aorta, intracranial vessels, superior mesenteric artery, and the large arteries to the extremities (Weintraub and Abrams, I968). Aneurysms occurring in the coronary arteries are commonly arteriosclerotic or congenital and are very rarely mycotic in origin (Daoud et al., I...

We present a case of hemothorax due to ruptured mycotic aneurysm in three intercostal arteries in a 40-year-old male with methicillin-resistant Staphylococcus aureus infective endocarditis (IE) due to intravenous drug use. Microcoil embolization and thoracotomy successfully achieved hemostasis. Mycotic aneurysm is a rare complication of IE and is usually found in the intracranial vessels. Ruptu...

A computerized fluoroscopic apparatus developed by members of the University of Wisconsin Medical Physics Section was used for 12 months to perform intravenous video arteriography. In previous papers, the apparatus was described and its use was illustrated for performing time subtraction intravenous video arteriography of the extracranial carotid arteries, the arteries of the abdomen and extrem...
