Thrombolytic therapy is the first choice for the treatment of acute ischemic stroke,while the recanalization rate of intravenous thrombolysis for large vessel occlusion stroke is low.As a representative.of endovascular treatment,endovascular mechanical thrombectomy can effectively recanalize the occluded cerebral vessel and inprove the outcome in patients with acute ischemic stroke.This article reviews the recent research progress and the future direction of intravenous thrombolysis bridging.

Transient ischemic attack(TIA) is one frequent type of acute ischemic cerebral vascular disease.Much advancement has been made in the definition,aetiology,diagnosis and therapy of TIA in recent years.Carotid endarterectomy and carotid angioplasty and stenting is the latest therapy of carotid artery stenosis.

Antiplatelet therapy is commonly used for the secondary prevention of embolic stroke of undetermined source (ESUS). However, the embolic source of ESUS is extremely heterogeneous, and the effect of antithrombotic therapy is different. This article describes the etiology and secondary prevention research progress of ESUS, in order to provide reference for clinical diagnosis and treatment.

Cerebral venous sinus thrombosis (CVST) in children has been previously regarded as a rare cerebrovascular disease. With the development of neuroimaging, we have more knowledge and understanding about CVST in children. The etiologies of CVST can be divided into infectious and noninfectious. Its clinical manifestations are various and lack of specificity. These characteristics make the clinical diagnosis of CVST have some difficulties.Now, it is considered that in combination with magnetic resonance imaging and magnetic resonance venography is the best means of diagnosis of CVST. Anticoagulation is the preferred treatment for CVST. Interventional thrombolysis, mechanical thrombectomy or decompressive craniotomy can be used for children whose symptoms continue to deteriorate after systematic anticoagulation therapy. The prognosis of CVST is relatively good if it is diagnosed and treated in time.

Cervical arterial dissection is an important cause resulting in stroke, particularly in young adults. The clinical manifestation of cervical arterial dissection may be various, and imaging examinations have a great value in the diagnosis of cervical arterial dissection. At present, anticoagulation and anti-platelet aggregation are the most important medication, while intravascular intervention is a new option for patients failed to respond to medical treatment. This article reviews the recent progress in the diagnosis and treatment of cervical arterial dissection.

Objective Proteinuria is in close relation with arteriosclerosis,but little investigation was made on the correlation between ankle-brachial index( ABI) and proteinuria in patients with acute cerebral infarction. Methods 271 consecutive patients with acute cerebral infarction were enrolled from January 2013 and December 2013, which were divided into 2 groups ( patients with proteinuria and patients without proteinuria) according to urine analysis.ABI of all patients was measured and stratified into 4 groups:ABI≤0.9 (low);0.9

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.

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.

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

Objective To study the effect of mild hypothermia on neuronal apoptosis and Bcl 2,Bax during cerebral ischemia in middle cerebral artery occlusions(MCAO) in rats.Methods The model of MCAO was set up in rats using the Longa's way,and mild hypothermia was treated for 0.5h,1h,3h. After reperfusion(24h) the rat brains were cut into three sections for TUNEL staining and Bcl 2?Bax protein immunohistochemical staining.Results 1)The numbers of apoptotic cells and Bax cells in the mild hypothermia group(1h, 3h) decreased remarkable as compared with the control group( P
