Complete endovascular arch replacement by in situ fenestration technique requires maintenance of cerebral perfusion during the fenestration procedure by an extracorporeal femoral-carotid bypass. The bypass has the disadvantages of being invasive, requiring a pump and shunting blood extracorporeally. This report describes bench testing and an in vivo experimental animal setup ...

: In an era of indocyanine angiography (ICG), the routine use of intra-operative angiography (IOA) in the surgical treatment of intracranial aneurysms and arteriovenous malformation (AVM) is controversial. We assess the safety and efficacy of IOA and determine predictors of clip readjustment. : Between 2003 and 2011, IOA was performed ...

The left internal mammary artery (LIMA) is a widely used conduit during coronary artery bypass graft (CABG) surgery because of its excellent long-term patency. Although large LIMA side branches are typically ligated during the surgery, the occurrence of a coronary steal phenomenon related to these side branches following surgery remains ...

: Previous studies have shown that extracranial-intracranial (EC-IC) bypass surgery has no preventive effect of subsequent ipsilateral ischemic stroke in patients with symptomatic atherosclerotic internal carotid occlusion and hemodynamic cerebral ischemia. However, few studies have assessed whether an urgent EC-IC bypass surgery is an effective treatment for main trunk stenosis ...

INTRODUCTION: Diagnosis of arterial ischemic stroke in pediatric patients is often delayed due to the uncertainty and variability of clinical symptoms. Early diagnosis of arterial ischemic stroke can bring a favorable prognosis with prompt thrombolytic therapy or stent insertion, via transfemoral cerebral arteriogram. Acute thrombolytic therapy is rarely attempted in ...

The success of allotransplants is critically dependent on both tissue viability and efficient removal of potentially toxic cryopreservants. In this study we analysed the dimethyl sulphoxide (Me2SO) content of cardiovascular tissue samples stored in tissue banks and optimized a washing protocol to be used before surgical implant. We compared the ...

Coronary stents, especially drug eluting stents (DES), have revolutionized the practice of interventional cardiology. Newer stents are manufactured by altering basic design characteristics to tackle complex coronary morphologies more effectively. Alteration in one particular attribute might affect other attributes adversely. Even though, reduction in the number and alteration of the ...

Intra-aortic balloon pumping increases myocardial oxygen supply and decreases myocardial oxygen demand by inflation and deflation of the balloon. This leads to increased perfusion of the coronary arteries during diastole. This technology has been used for critically ill cardiac patients for more than 30 years. The literature suggests that preoperative ...

Many patients with congenital heart disease and systemic-to-pulmonary shunts develop pulmonary arterial hypertension (PAH), particularly if the cardiac defect is left unrepaired. A persistent increase in pulmonary blood flow may lead to obstructive arteriopathy and increased pulmonary vascular resistance, a condition that can lead to reversal of shunt and cyanosis ...
