INTRODUCTION Blood blister-like aneurysms (BBAs) are fragile and difficult to treat. Routine surgical and endovascular treatment methods, such as clipping, clip wrapping, primary coiling, or stent assisted coiling, have relatively high morbidity and mortality rates. In this study, we report clinical and angiographic results for treatment of ruptured BBAs(More)
Type 4 spinal vascular malformations are called perimedullary arteriovenous fistulae, in which there is a shunt between a radicular artery and intradural veins. We report the spinal MR imaging and angiography findings of the angiography-induced closure of a type 4 spinal vascular malformation.
OBJECTIVE Intrathecal gadolinium (Gd)-enhanced magnetic resonance (MR) cisternography is a newly introduced imaging method. Two main objectives of this study were to investigate the sensitivity of Gd-enhanced MR cisternography for presurgical localization of cerebrospinal fluid (CSF) leaks in patients with CSF rhinorrhea and to study the potential long-term(More)
 Extraneural scarring is one of the factors negatively influencing the result of peripheral nerve surgery. Many organic materials have been used to prevent fibrosis. The effect of aprotinin on peripheral nerve scarring in rats was investigated in this study. Three types of surgical intervention were carried out; namely external neurolysis (I), abrasive(More)
This case involved a 26-month-old boy who had recurrent hemorrhagic venous infarction caused by venous sinus occlusion. Distension and enlargement of the cavum septi pellucidi (CSP) and cavum vergae (CV), along with hydrocephalus, was detected during the course of the disease and was observed to regress together with resolution of the venous occlusion.(More)
BACKGROUND This is a report of 5 patients treated surgically for SCMs. METHODS During the period from 1998 to 2003, 5 patients (4 male and 1 female) harboring SCMs were treated surgically (all of them underwent complete surgical removal). Patients' ages ranged between 22 and 57 years (mean age, 46 years). Median duration of symptoms was 31 months (1-120(More)
BACKGROUND Risks related to rebleeding of a ruptured intracranial aneurysm have decreased. However, ischemic neurologic deficits related to vasospasm are still the leading causes of mortality and morbidity. It is well known that vasospasm is a dynamic process affected by various factors. The severity of vasospasm in animal models and clinical observations(More)
BACKGROUND Bacterial brain abscesses can be diagnosed and treated with stereotactic aspiration. METHODS From 1991 to 1997 we have used computed tomography-guided stereotactic aspiration to diagnose and treat 21 patients with a total of 58 bacterial brain abscesses. The ages of the patients ranged from 4 to 72 years (median 25 years); 11 of these 21(More)
A patient with an intrasellar germinoma leading to pituitary stalk thickening is reported. The patient, a 24-year old woman, presented with hyperprolactinemia, secondary hypothyroidism, and hypogonadotropic hypogonadism with no evidence of diabetes insipidus. Cerebrospinal fluid (CSF) examination revealed an increased number of lymphocytes and histiocytes.(More)
OBJECTIVE Glutamate antagonists are very attractive drugs in laboratory works to protect neural tissue against ischemia. In this work, the effects of magnesium, MK-801 and combination of magnesium and MK-801 on blood-brain barrier (BBB) and brain edema after experimentally induced traumatic brain injury are evaluated. METHODS A standard closed head injury(More)
