Flowing emboli in the circulatory system cause fatal diseases such as stroke or pulmonary embolism. Conventional transcranial Doppler ultrasound for detection of emboli requires precise positioning by experienced examiner. In the present study, an easier emboli detection device by visualizing perspective view of blood vessel is proposed. The perspective image was obtained with continuous wave (CW) Doppler ultrasound from 2-dimensional array probe. CW Doppler signal from each element was focused by novel beam forming algorithm to obtain en face images at arbitrary depth to form perspective image...

OBJECTIVE: We sought to assess the early success and safety of catheter-directed, ultrasound-assisted (CDUA) thrombolysis for acute pulmonary embolism (PE) in patients deemed to be "high risk" for thrombolytic therapy. METHODS: A retrospective evaluation of patients who underwent CDUA pulmonary thrombolysis in our practice during 39 months is reported. There were 91 patients considered, all of whom presented with acute PE as diagnosed by computed tomography angiography...

Pulmonary embolism (PE) is a serious and prevalent cause of vascular disease. Nevertheless, optimal treatment for many phenotypes of PE remains uncertain. Treating PE requires appropriate risk stratification as a first step. For the highest-risk PE, presenting as shock or arrest, emergent systemic thrombolysis or embolectomy is reasonable, while for low-risk PE, anticoagulation alone is often chosen. Normotensive patients with PE but with indicia of right heart dysfunction (by biomarkers or imaging) constitute an intermediate-risk group for whom there is controversy on therapeutic strategy...

Pulmonary embolism (PE) is a major cause of both acute and long-term morbidity for a large number of patients worldwide, and massive PE is frequently fatal. Right ventricular (RV) dysfunction is a key determinant of prognosis in the acute phase of PE. Patients with clinically overt RV failure, that is, with cardiogenic shock or persistent hypotension at presentation (acute high-risk PE), are clearly in need of immediate reperfusion treatment with systemic thrombolysis or, alternatively, surgical or catheter-directed techniques...

Acute pulmonary embolism (PE) is a major cause of morbidity and mortality and is classified as massive (high risk), submassive (intermediate risk), or nonmassive (low risk) based on the hemodynamic status and clinical characteristics of the patient. At this time, the management of patients with submassive PE remains controversial and approaches for improving risk assessment are critical. In this review, we discuss several echocardiographic methods to assess right heart function that may aid in the risk assessment of patients with acute PE...

Zhongheng Zhang
Echocardiography is an invaluable tool in the management of patients with extracorporeal cardiopulmonary resuscitation (ECPR) and subsequent extracorporeal membrane oxygenation (ECMO) support and weaning. At the very beginning, echocardiography can identify the etiology of cardiac arrest, such as massive pulmonary embolism and cardiac tamponade. Eliminating these culprits saves life and may avoid the initiation of extracorporeal cardiopulmonary resuscitation. If the underlying causes are not identified or intrinsic to the heart (e...

Deep venous thrombosis (DVT) affecting the extremities is a common clinical problem. Prompt imaging aids in rapid diagnosis and adequate treatment. While ultrasound (US) remains the workhorse of detection of extremity venous thrombosis, CT and MRI are commonly used as the problem-solving tools either to visualize the thrombosis in central veins like superior or inferior vena cava (IVC) or to test for the presence of complications like pulmonary embolism (PE). The cross-sectional modalities also offer improved visualization of venous collaterals...

The aim of the present study was to report the case of a 55-year-old female patient with a sizeable (7.1×6.2 cm) hepatocellular carcinoma (HCC), who succumbed to massive pulmonary artery embolism. The main symptoms included sudden thoracodynia, dyspnea and transient coma. The initial diagnosis was HCC according to the typical abdominal ultrasound and triple-phase abdominal computed tomography (CT) findings, chronic hepatitis B infection and elevated α-fetoprotein levels (1,036 µg/l; normal, 0-20 µg/l). Two days following admission, the patient developed recurrent chest pain and shortness of breath...

For a long time superficial thrombophlebitis has been thought to be a rather benign condition. Recently, when duplex ultrasound technique is used for the diagnosis more and more often, the disease is proved to be more dangerous than anticipated. Thrombosis propagates to the deep veins in 6-44% and pulmonary embolism was observed on the patients in 1,5-33%. We can calculate venous thromboembolic complications on every fourth patient. Diagnosis is clinical, but duplex ultrasound examination is mandatory, for estimation of the thrombus extent, for exclusion of the deep venous thrombosis and for follow up...

INTRODUCTION: Stem cell transplantation is today's procedure of choice for management of various hematopoietic malignant and severe immunogenic disorders. High Resolution Computed Tomography (HRCT) is a common technique for the diagnosis of pulmonary complications in stem cell transplant recipients. There are a large number of complications which can complicate the post-transplant period. AIM: To study the role of HRCT chest in stem cell transplant patients developing pulmonary complications, detect any evidence of infection, detect clinical signs of lung infections, Graft versus Host Disease (GvHD) or other regimen related toxicities outlined earlier, detect any evidence of GvHD and correlate these clinical signs with radiological changes in the lungs...

PURPOSE: Inferior vena cava filters (IVCFs) are used in patients with a high risk of pulmonary embolism in situations when the use of blood thinning drugs would be inappropriate. These filters are implanted under x-ray guidance; however, this provides a dose of ionizing radiation to both patient and physician. B-mode ultrasound (US) imaging allows for localization of certain implanted devices without radiation dose concerns. The goal of this study was to investigate the feasibility of imaging the placement of absorbable IVCFs using US imaging to alleviate the dosage concern inherent to fluoroscopy...

We enjoyed the article by Nazerian et al., Diagnostic performance of Wells' Score combined with point-of-care lung and venous ultrasound in suspected pulmonary embolism [1]. We recognize the need to safely exclude the diagnosis of pulmonary embolism (PE) without the use of ionizing radiation through use of evidence-based clinical decision aids (CDAs). We agree that point-of-care ultrasound can play a role in the evaluation of suspected PE. This article is protected by copyright. All rights reserved.

We thank the Authors for their interest in our study [1] and the questions raised. Our response begins from their conclusion: "…we fear that uWells' may create more noise than signal in the already murky PE milieu". We find curious that two strongly evidence based applications of point-of-care ultrasound (POCUS) added to the clinical evaluation might create confusion rather than resolving challenging questions.

INTRODUCTION: The persistent ductus arteriosus remains a common congenital pathology. Although percutaneous closure of wide channels using an Amplatzer Duct Occluder is an attractive alternative to the surgical treatment, this prosthesis is not recommended for infants weighing less than 6kg. AIM OF THE STUDY: The objective was to evaluate the efficacy and safety of this prosthesis in low-weight children. PATIENTS AND METHODS: The records of children weighing less than 6kg who underwent closure with the Amplatzer Duct Occluder prosthesis between January 2010 and December 2014 were retrospectively analyzed...
