c Right ventricular dysfunction (RVD) is the most common cause of short-term mortality in patients with acute pulmonary embolism (PE).1 Shock and hemodynamic instability, defined as systolic blood pressure below 90mmHg or a fall of more than 40mmHg, is a clinical marker of high risk and identifies patients who may benefit from early thrombolysis.2 However, in PE patients without hemodynamic com...

Early diagnosis and surgical correction is highly important for survival. In the evaluation of TAPVC, imaging methods have been used. Recent advances Total anomalous pulmonary venous connection (TAPVC) is a rare congenital cardiac anomaly in which the pulmonary veins fail to connect with the left atrium and connect directly to the right atrium or to one of the systemic veins. Early diagnosis an...

Pulmonary embolus (PE) is a life-threatening illness that can be fatal if not treated with anticoagulation in timely fashion. Without the use of CT angiography for direct visualization thrombus pulmonary arteries or downstream vessels, diagnosis PE challenging. Point-of-care ultrasound (POCUS) bedside method highly effective directly evaluating deep vein thrombosis (DVT) and indirectly PE. In t...

BACKGROUND It is unknown whether the observed increase in computed tomography pulmonary angiography (CTPA) utilization has resulted in increased detection of pulmonary emboli (PEs) with a less severe disease spectrum. METHODS Trends in utilization, diagnostic yield, and disease severity were evaluated for 4,048 consecutive initial CTPAs performed in adult patients in the emergency department ...

UNLABELLED Unilateral pulmonary artery agenesis without any cardiovascular malformation is a rare anomaly. We present the imaging findings of a patient who was diagnosed as isolated left pulmonary artery agenesis. A 27-year-old female patient was admitted to our hospital due to dyspnea during exercise for five years. Chest X-ray revealed minimally small left pulmonary hilum and left lung. She w...

Background and Aim: Pulmonary thromboembolism is an important clinical problem in the patients after major surgeries and is often difficult to diagnose because of nonspecific clinical symptoms. Diagnosis of pulmonary embolism is based on medical imaging methods. The aim of this study was to evaluate the results of CT pulmonary angiographies of the patients with primary clinical diagnosis of pul...

The patient was a 69-year-old man with progressive dyspnea during the previous 5 years and no history of thromboembolic events. By means of spiral CT scanning and multiplanar digital subtraction angiography of the pulmonary arteries, chronic thromboembolic pulmonary hypertension was diagnosed. Mean pulmonary artery pressure and pulmonary vascular resistance were elevated to 46 mm Hg and 890 dyn...
