Objective:To analyze the correlation between intra-extracranial arterial stenosis and silent cerebral infarction(SCI) in the elder with essential hypertension(EH). Methods:The results of color duplex ultrasonography(Duplex) and digital subtraction angiography(DSA) examination of 86 patients with essential hypertension complicated silent cerebral infarction were analyzed.The incidence of intra-and extracranial arterial stenosis and arthrosclerosis plaque were calculated.The comparative value of Duplex and DSA for evaluating atherosclerosis of extracranial carotid artery was analyzed using statistic methods. Results:The incidence of arthrosclerosis plaque was higher in SCI group than that in normal control group(62.79%,24%,P

Endovascular intervention is an effective method in the treatment of cerebrovascular stenosis. With the advancement of techniques and improvement of equipment, the application area of this treatment is expanding and the number of patients treated is increasing. Accordingly, the use of contrast media is improving continuously in endovascular intervention. An increasing number of contrast media-related complications have also been reported. This paper briefly reviews the contrast media-related complications and their management in endovascular intervention.

Intracranial stentosis is one of the important causes of ischemic stroke. In recently years, with the continuously development of endovascular intervention, angioplasty and stenting have become effective treatment options for intracranial stenosis. However, the indications, technical points, complications and prognosis of this treatment remain to be investigated and explored.

Approximately one-quarter of ischemic stroke occurred in vertebrobasilar artery system. Atherosclerotic vertebrobasilar artery stenosis is one of the major causes of posterior circulation stroke. In addition to the conventional medical and surgical treatment, endovascular intervention has received more and more attention, and it has become the most promising therapeutic approach.

Endovascular treatment is becoming a novel technique in the treatment of carotid stenosis. Since this technique is in its infancy, there are many controversies on this technique and theory now. This paper briefly reviews the most recent advances in endovascular treatment of carotid stenosis.

Cerebral venous thrombosis is a rare cerebral venous occlusive disease. Its clinical manifestations are variable, and this may lead to misdiagnosis or mistreatment. Prompt treatment is essential to improve its prognosis. This article reviews the recent treatment methods, especially the interventional endovascular treatment.

Cerebrovascular Intervention is to study the subject of diagnosing and treating cerebrovascular disease with interventional endovascular techniques monitored and guided by neuroimaging. With the continuous development of computer, imaging and angiography techniques, their study method and category are being innovated and expanded continuously in recent years. This article reviews the novel techniques of imaging diagnosis, intra-arterial thrombolysis, angioplasty and endovascular embolization in cerebrovascular diseases, and also evaluates their clinical applications.

Objective To study the relationship between Oxfordshire Community Stroke Project(OCSP)classification and middle cerebral artery(MCA)lesions detected by digital subtraction angiography among patients with acute MCA territorial infarction.Methods One hundred and fifty-four patients with acute MCA territorial infarction,who were obtained from Jinling Hospital during May 2002 to December 2005,were classified into total anterior circulation infarction(TACI),partial anterior circulation infarction(PACI)and lacunar infarction(LACI).Results Compared with LACI subtype,prevalence of MCA main stem occlusion in patients with TACI subtype was higher(P

Cerebral autosomal dominant arteriopathy with subcortical infarcts and lecukoencephalopathy (CADASIL) is a recently described neurovascular disease affecting young to middle aged individuals. The disease is caused by mutations in the Notch3 gene located in the long arm of chromosome 19. The disease clinically is characterized by migrainous headaches ,mood disturbances, focal neurologic deficits, transient ischemic attaches, strokes and dementia. Pathologically, the disease is characterized by a stereotypic degeneration of the arterial walls with deposition in the media of a nonatheromatous,(nonamyloidotic) substance that under the electron microscope (EM) appears as a granular osmiophilic material (GOM). A review of current literature is presented concerning the clinical, radiological, pathologic and genetic feature of CADASIL.

Objective:To investigate the effect of edaravone injection on the neuron-specific enolase(NSE) concentration in serum from patients with acute cerebral infarction.Methods:The NSE concentrations in serum from 35 patients were measured by an ELISA method.Neurological deficit was scored for clinical effect assessment.Results:Serum NSE levels and neurological deficit scores in edaravone treating group significantly decreased at d 3 compared with those in routine therapy group((P
