A trial fibrillation is the most common sustained arrhythmia worldwide (1), and catheter-based pulmonary vein isolation (PVI) is becoming a dominant approach to its management. Stroke and transient ischemic attack are known risks of PVI (2). To improve PVI safety, atrial thrombus needs to be excluded. Traditionally, patients undergo elective computed tomography angiography or magnetic resonance...

Introduction: Pulmonary embolism (PE) is a common lethal disease that its clinical symptoms may be seen in many other diseases. Computed tomography pulmonary angiography (CTPA) is a valuable diagnostic modality for detection of PE. In addition, it can accurately detect the other diseases with clinical symptoms similar to PE. The aim of this study is to evaluate the frequency of PE and nonemboli...

BACKGROUND AND OBJECTIVE Computed tomography angiography plays a major role in the diagnosis of pulmonary embolism. Radiation dose associated with it is a major concern; therefore it is important to optimize protocols and techniques to ensure minimum radiation dose. METHODS The study compares two protocols i. Conventional Timing Bolus CT protocol and Delayed Timing Bolus protocol used to assi...

background: considering the importance of using more appropriate imaging technique for accurate diagnosis of pulmonary thromboembolism (pte) with less side eff ects, we aimed to evaluate the quality of pulmonary 64-multidetector computed tomographic (mdct) angiography in pregnant and postpartum women with suspected pte in isfahan. materials and methods:in this descriptive study, radiological fi...

We present the case of a 54-year-old male patient diagnosed with a right upper lobe lung cancer and was referred for resection. Positron emission tomography-computed tomography scan showed a prominent vascular structure in the right lung, suspicious for vascular malformation. A computed tomography angiography was done, demonstrating an intercostobronchial trunk-pulmonary artery fistula. There w...

Total anomalous pulmonary venous connection (TAPVC) is a rare congenital anomaly of the pulmonary veins drainage. In this entity, the pulmonary veins, instead of draining to left atrium, connect abnormally to the systemic venous circulation. A right-to-left shunt is obligatory for survival. Based on its type and degree of pulmonary venous obstruction, TAPVC may result in pulmonary hypertension ...

lung contusion is an entity involving injury to the alveolar capillaries, without any tear or cut in the lung tissue. this results in accumulation of blood and other fluids within the lung tissue. the excess fluid interferes with gas exchange leading to hypoxia. the pathophysiology of lung contusion includes ventilation/perfusion mismatching, increased intrapulmonary shunting, increased lung wa...

conclusions invasive treatment of dialysis patients for cvc related complications is effective and durable during mid-term follow up with no re-intervention, clinical episode of vte or death. cta is a reliable mean for the diagnosis of cvc related complications. methods this is a retrospective analysis of prospectively collected data of dialysis patients treated for cvc-related complications an...
