results prediction of the rca as culprit lesion using tierala's algorithm was 86% sensitive and 50% specific. prediction of lcx occlusion based on st-elevation ≥ 1 mm in v6 was 87% specific (p = 0.005). sum of st elevation in leads v5 and v6 more than 2.5 mm, was a good marker of lcx prediction (p = 0.044). st-elevation in v4r was 48% sensitive and 89% specific for rca prediction (p = 0.004). w...

PURPOSE Myocardial infarction in children with total occlusion of a coronary artery after Kawasaki disease is rare due to multiple collateral vessels. We aimed to investigate the changes in coronary perfusion associated with coronary artery occlusion after Kawasaki disease. MATERIALS AND METHODS Eleven patients with coronary artery occlusion after Kawasaki disease were investigated. Serial co...

1024x768 normal 0 false false false en-us x-none ar-sa background and objective: numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. one physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. in this study, we can predict hem...

This is a case report of an 83-year-old female who presented to the emergency department within eight hours symptom onset. A CT angiogram revealed distal basilar artery occlusion, as well perfusion deficit in right superior cerebellar artery. Her symptoms fluctuated, and she was started on heparin drip, but later evening her worsened. mechanical thrombectomy performed by interventional radiolog...

Background. The current state of interventional cardiology is aimed at reducing the number probable complica-tions procedures and increasing patient comfort. That why there was a stage evolution changing endovascular ap-proaches from transfemoral to transradial. But despite significant benefits transradial access, it leaves behind some important complications. One such complication occlusion ra...

A patient is presented with a right central retinal artery occlusion and subjective bruit over right ear. Digital compression of the right temporal artery eliminated the bruit and release reproduced the bruit. Carotid arteriogram showed bilateral internal carotid occlusion with a prominent right temporal artery. This sign reflects compensatory hyper-perfusion of the external carotid artery due ...

Hemodynamic changes were examined with an ultrasonic Doppler flowmeter and with a sound-spectrograph in 5 patients with internal carotid giant aneurysms or with recurrent laryngeal cancer undergoing gradual carotid occlusion. The ultrasonic Doppler technique was useful for preoperative assessment of intracranial cross-filling and as a practical guide for the graded reduction of blood flow in th...

Distal embolization resulting from carotid angioplasty and stenting (CAS) occurs mainly in the cerebral hemisphere. We report a case of ophthalmic artery occlusion after carotid revascularization. A 75-year old man received emergency CAS for cervical internal carotid artery occlusion. Two months later, the patient was readmitted for decreased visual acuity. We found ophthalmic artery occlusion ...

BACKGROUND AND PURPOSE Acute basilar artery occlusion portends high risk of stroke and death. Thrombolysis or endovascular therapy has been limited to patients who present within hours of symptom onset. Without recanalization, acute basilar artery occlusion almost always results in death or severe disability. SUMMARY OF CASE We report a case of basilar artery occlusion and successful endovasc...

Objective: To elucidate the value of early computed tomographic (CT) signs of stroke in predicting the occlusion site in the cerebral arteries. Patients: 105 consecutive patients with acute embolic stroke affecting the anterior circulation. Methods: Four early signs were evaluated on cranial CT within six hours of stroke onset: loss of the insular ribbon (LIR); attenuation of the lentiform nucl...
