A typical patient with R-MCA undergoing stenting before (top row) and after (bottom surgery. 65-year-old male severe stenosis. (a) DSA showed that stenting, the stenosis was significantly alleviated, blood flow recanalized, distal branches were well visualized. (b) DWI no obvious high signal operation. (c) Preoperative 3D pcASL low perfusion area visible in M6, postoperative had returned to nor...

Introduction: Meatal stenosis is a recognized complication of circumcision done during nappy aged boys as a late presentation. The objective of this study was to describe the incidence of documented meatal stenosis in boys circumcised in infantile period. Method: Meatal stenosis was defined as change in appearance of the delicate lips of the urinary meatus, with loss of ellipticated shape to a...

The delayed upstroke of the arterial pulse in valvular aortic stenosis has been attributed, in part, to prolonged left ventricular emptying. Left ventricular emptying rate, however, has not been measured in aortic stenosis. We assessed the rate of left ventricular emptying by computer analysis of biplane cineangiograms in seven normal subjects, six patients with mild to moderate aortic stenosis...

conclusion we conclude that coronary calcium scoring provided useful information in the management of patients. in cacs less than 100, it has a npv of 87% in excluding significant stenosis in patients with the risk of cad but it does not have enough diagnostic accuracy for surely excluding coronary stenosis, so we should perform a combination of cacs and coronary ct angiography for patients. re...

Background & Aims: The clinical value of T wave inversion (TWI) in the lead aVL in diagnosing coronary artery disease (CAD) remains unclear. Hence, we aim to evaluate the association between TWI in the aVL lead and the severity and location of coronary artery stenosis in elective coronary angiography. Material and Method: Electrocardiograms (ECGs) of 167 consecutive patients undergoing electiv...

the left ventricular aneurysm is one of the most significant complications of myocardial infarction and is defined as the expansion of the ventricular wall. the coronary artery aneurysm is characterized by an abnormal dilation of the localized portion of the coronary artery, and its main cause is atherosclerosis. we herein report an unusual case of coronary artery and left ventricular aneurysms...

Introduction: Circumcision is proposed as the world’s oldest and most controversial operation and meatal stenosis as the most common complication of neonatal circumcision. Published studies in Iran are deficient regarding this complication. This research shows the rate of meatal stenosis in children less than one year in Birjand-Iran. Methods: This descriptive study incorporated all children y...

conclusions the coronary sinus flow per minute is the most accurate parameter among the three echocardiographic parameters mentioned above for the assessment of significant stenosis of the coronary artery. results flow (ml/minute), flow/lvm (ml/minuteg) and lv (d-s) mass a-l all correlated significantly with the percentage of stenosis (r = -0.64, p < 0.001; r = -0.47, p < 0.001; r = -0.56, p < ...
