we report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. we present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery – the theories and treatments are discussed. a 85 year-old female was admitted under the care of the  cardiothoracic team with signs ...

  Background :In addition to diagnosing the acute myocardial infarction (MI), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting MI. Many studies have been conducted to predict the occlusion site by interpreting the ST segment deviations in Electrocardiogram (ECG).Additional posterior and right precor...

conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

Background: Transradial access is one of the main access techniques in angiography. This method is technically more difficult as it is associated with radial artery occlusion. Radial artery cannulation from the dorsal surface of the hand in the snuffbox area has been introduced as a suitable solution to overcome some of the disadvantages of the standard radial artery method. This study was cond...

Objective(s):The present study investigated the effect of long-term mild cerebral hypoperfusion induced by permanent unilateral (right) common carotid artery occlusion (UCO) on the dorsal hippocampal neurons in rats. Materials and Methods:Sixty four male Sprague-Dawley rats aged 4 months were divided into two groups of sham and UCO. These two groups were further divided into 4 sets of histopath...

one of the signifiant risk factor of ischemic stroke is carotid artery occlusion. although surgical treatment was disappointing in these patient but there is a growing reports of sucessful endovascular treatment recently. in this technical note 56 year-old man who suffered from bilateral carotid occlusion was revascularized. the penumbra thrombosuction system was applied to reduce the risk of d...

Collateral circulation plays an important role in protecting brain tissue from ischemic damage acute cerebral artery occlusion, and various imaging modalities are used to evaluate collateral circulation. Angiographic techniques, such as digital subtraction angiography multiphase computed tomography (CT) angiography, directly show Meanwhile, hyperintense vessels on f luid-attenuated inversion re...

Τransradial artery access has recently gained widespread acceptance as the preferred approach for coronary angiography and interventions, due to its lower incidence of bleeding vascular complications compared transfemoral access. However, thrombotic occlusion radial emerged most common complication this method, impeding use in future creation arteriovenous fistulae hemodialysis patients, or a g...

An occlusion of the artery Percheron (AOP) is a rare clinical condition that remains diagnostic challenge for physicians given its variable presentation. This infarction result an anatomical variant single vessel arising from posterior cerebral artery. Occlusion AOP results in levels alteration consciousness, vertical gaze palsy, and memory impairment. Unfortunately, due to this presentation th...
