Cerebral hyperperfusion syndrome is a rare but serious complication of carotid revascularization, and characterized by ipsilateral headache, hypertension, seizures, focal neurological deficits. Therefore, treatment strategies are directed towards regulation blood pressure limitation rises in cerebral perfusion to prevent edema or hemorrhage, especially during several days after endarterctomy st...

BACKGROUND AND PURPOSE Cerebral venous thrombosis is a rare entity that can be difficult to manage. Intrasinus thrombolysis is an increasingly applied intervention, but this modality carries an increased risk of hemorrhage. We describe for the first time an option with a potentially lower incidence of intracranial bleeding, the combination of the AngioJet rheolytic thrombectomy catheter with in...

Background and Purpose: Serial changes of anti-platelet-aggregating activity in the endothelial cells after experimental subarachnoid hemorrhage were studied in 30 feline two-hemorrhage models. Methods: One hour or 2, 4, 7, or 14 days after mimic subarachnoid hemorrhage, ADP (40 mg/kg) was infused into the basilar artery via the right vertebral artery to activate circulating platelets. Immediat...

BACKGROUND AND PURPOSE Intra-arterial treatment of proximal occlusions in the cerebral circulation have become an important tool in the management of acute ischemic stroke. Our goal was to evaluate the safety and efficacy of intra-arterial acute ischemic stroke treatment performed in our institution in consecutive patients with anterior circulation occlusion during 2000-2011. MATERIALS AND ME...

INTRODUCTION To the best of our knowledge, the association between air travel and intra-tumoral hemorrhage in pediatric populations has never been described previously. CASE PRESENTATION We report the case of a two-and-a-half-year-old Caucasian, Iranian boy with a hemorrhaging brain tumor. He had a posterior fossa midline mass and severe hydrocephalus. He had been shunted for hydrocephalus fo...

INTRODUCTION Cerebral vasospasm is a major cause of delayed ischemic cerebral injury, typically occurring 3-14 days after subarachnoid hemorrhage (SAH). Ultra-early vasospasm is defined as angiographic vasospasm observed within 48 h of SAH onset. Immediate vasospasm at the time of aneurysmal rupture has been suspected, but has not been previously reported. We describe a case of immediate, trans...

Intracerebral hemorrhage can occur due to primary and metastatic intracranial neoplasm. In half of the cases it may be the first manifestation of the tumor. It is also known that metastatic tumors bleed more than the primary CNS tumor [1]. Metastatic choriocarcinoma is a rare but an important cause of intra cerebral hemorrhage in female patients in reproductive age group. Choriocarcinoma (gesta...

Subarachnoid hemorrhage is a devastating condition due to many etiologies, accounting for 5% of all stroke patients. Rupture of an intracranial aneurysms is most frequent causative factor. The diagnosis is usually easy as clinical symptomatology is quite classical, but diagnosis of warning leaks requires increased degree of suspicion. Non contrast computerised scan (CT) of head is initial inves...

A 14-year-old boy with Loeys-Dietz syndrome (LDS) had an acute neurologic decline 6 days after a subarachnoid hemorrhage. Cerebral angiography at presentation did not show an aneurysmal source of the hemorrhage. However, on post-bleed day 6 the patient experienced an acutely worsening headache and subsequently lost consciousness. Head CT showed new subarachnoid blood and repeat angiography demo...
