PURPOSE Vein pouch aneurysms are the most commonly created experimental lesions in neuroendovascular research. We sought to determine whether an experimental aneurysm that is derived from a pancreatic elastase-digested arterial sac (EDASA) models the histology and morphology of human cerebral aneurysms more accurately than the vein pouch aneurysm does. METHODS EDASAs were created in the commo...

PURPOSE To describe a patient with transient third nerve palsy as the possible presenting sign of intracranial arteriovenous malformation. METHOD Case report. RESULT A 24-year-old female presented to ophthalmic casualty with sudden onset binocular diplopia and was diagnosed to have right sided partial third nerve palsy. Within 30 hours the third nerve palsy had recovered completely. A MRI s...

High plasma levels of total homocysteine (tHcy) are a risk factor for deep vein thrombosis. Because no information on the relationship between cerebral vein thrombosis and hyperhomocysteinemia is available, a case–control study of 121 patients with a first episode of cerebral vein thrombosis and 242 healthy control subjects was carried out. Fasting plasma levels of tHcy and their postmethionine...

BACKGROUND AND PURPOSE The impact of deep cerebral veins on neurologic outcome after intravenous thrombolysis in patients with acute ischemic stroke is unclear. We investigated the relationship between the appearance of deep cerebral veins on susceptibility-weighted imaging and neurologic outcome in patients who underwent thrombolysis. MATERIALS AND METHODS We retrospectively analyzed 109 con...

OBJECTIVES To compare the prevalence of prothrombin G20210A in patients with objectively confirmed cerebral vein or cortical vein thrombosis against healthy controls, and evaluate geographical variations. DESIGN Systematic review and meta-analysis of case control studies. METHODS We conducted a systematic review of electronic databases including MEDLINE and EMBASE. The main outcome was the ...

A blood clot in the veins that drain the blood from the brain is called a sinus or cerebral vein thrombosis. It is an uncommon type of clot, affecting about 1500 people in the United States per year. Normally, blood is transported through arteries into the brain, where it delivers oxygen and nutrients. Once the blood has done its job, it collects into small veins (known as cerebral veins) that ...

globin serves as an intrinsic contrast agent for cerebral veins which contain deoxygenated blood. Other extravascular blood degradation products with paramagnetic properties such as methemoglobin, hemosiderin and ferritin also create a contrast in SWI. In this sequence in order to increase the visualization of the smaller veins, a phase mask obtained from the magnetic resonance (MR) phase image...

RATIONALE Cerebral venous thrombosis (CVT) comprises a group of cerebral vascular diseases resulting from cerebral venous outflow obstruction caused by various etiologies. The etiology of CVT is complex, including infectious and noninfectious factors. The diagnosis is difficult. As a result, many patients are misdiagnosed or never diagnosed. This patient was diagnosed with CVT due to unilateral...
