abstractbackground: as fluoroscopy or different angiographies are usually evaluated using tl dosimeter. thismethod is a time-consuming procedure therefore, radiologists are usually worried and unawareof their exact radiation dose received during each fluoroscopy or angiography. in this study, anew trend for quick estimation of effective dose based on measuring air-absorbed dose of thescattered ...
conclusions our case is the first report of ivus imaging of subclavian stenosis resulting from takayasu’s arteritis and provides insight into the pathology behind such lesions. introduction takayasu’s arteritis (ta) is a chronic, idiopathic, inflammatory disease that affects large elastic arteries, including the aorta and its main branches. no consensus exists currently on the superiority of su...
congenital anomalies of coronary arteries, albeit rare, may be significant contributors to angina pectoris, hemodynamic abnormalities, and sudden cardiac death. a 47-year-old man referred to us with atypical chest pain. electrocardiography demonstrated no significant ischemic changes, but cardiac troponin i test was positive. the patient underwent coronary angiography, which revealed a single c...
large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...
a 73-year-old woman who had undergone coronary artery bypass grafting for coronary artery stenosis six years ago, presented with right lower extremity claudication. angiography revealed right external artery stenosis. elective external iliac ptca was performed complicated with simultaneous external iliac artery and vein rupture that was an exceedingly rare event. retroperitoneal laparotomy with...
although gastrointestinal bleeding is common, hemobilia due to the rupture of hepatic artery pseudoaneurysm is uncommon. we report a case of hemobilia which was successfully treated via angiography.
conclusions coronary artery aneurysm should be a differential diagnosis in cases of mediastinal cyst and mass lesion. case presentation a 32-year-old woman presented with edema of the upper and lower limbs, palpitation, and chest pain, and was diagnosed with a giant right coronary artery aneurysm that had initially mimicked a mediastinal cyst. although computed tomography (ct) suggested a media...
Introduction: angiography, lead to increase patient’s levels of anxiety. Multiple therapies are used to reduce anxiety. This study aims to investigate the effect of the pressure of (Yintang and shenmen) points on the patients’ anxiety before the coronary angiography. Methods: This Single blind randomized controlled trial study was performed on 70 patients before angiography. Af...
Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...
Introduction: Although angiography is applied as a standard method for the diagnosis of coronary heart disease, it is a stressful experience for patients. Medication therapy for mitigating the pre-operation stress includes side effects. Objective: The present study aimed to determine the effect of auriculotherapy on the level of stress before coronary angiography in male patients hospitalized...
