Data on paediatric pulmonary embolism (PE) are scarce. We sought to systematically review the current literature on childhood PE and conducted a search on paediatric PE via PubMed (1946-2013) and Embase (1980-2013). There was significant heterogeneity in reported data. Two patterns were noted: classic thromboembolic PE (TE-PE) and in situ pulmonary artery thrombosis (ISPAT). Mean age of presentation for TE-PE was 14.86 years, and 51 % of cases were males. The commonest method for diagnosis of TE-PE was contrast CT with angiography (74 % of patients)...

A Ruggiero, N J Screaton
Acute pulmonary embolism (PE) is a life-threatening condition that requires prompt diagnosis and treatment. Recent advances in imaging allow acute and rapid recognition even by the non-specialist radiologist. Most acute emboli resolve on anticoagulation without sequelae; however, some emboli fail to fully resolve becoming endothelialised with the development of chronic thromboembolic disease (CTED). Increased pulmonary vascular resistance arising from CTED may lead to chronic thromboembolic pulmonary hypertension (CTEPH) a debilitating disease affecting up to 5% of survivors of acute PE...

Massive hemoptysis is a medical emergency and needs immediate treatment. It occurs in a wide variety of pulmonary diseases and typically originates from the bronchial arteries. We herein report a very rare case of a patient bleeding from a right phrenic artery-to-pulmonary artery fistula accompanied with focal bronchiectasis in the right middle lobe of the lung. In this case, multi-detector computed tomography was useful for clarifying the etiology and the abnormal anastomosis and facilitated effective angiographic embolization...

Spectral detector computed tomography (SDCT) is a novel technology that uses two layers of detectors to simultaneously collect low and high energy data. Spectral data is used to generate conventional polyenergetic images as well as dedicated spectral images including virtual monoenergetic and material composition (iodine-only, virtual unenhanced, effective atomic number) images. This paper provides an overview of SDCT technology and a description of some spectral image types. The potential utility of SDCT for cardiovascular imaging and the impact of this new technology on radiation and contrast dose are discussed through presentation of initial patient studies performed on a SDCT scanner...

We report a case of 34-year patient who had uncomplicated elective caesarean-section. Postoperatively, she developed sudden hypotension, bradycardia, dyspnea and disseminated intravascular coagulation (DIC), all signs associated with amniotic fluid embolism (AFE). Echocardiogram showed signs of acutely increased right ventricular after load including McConell's sign, i.e. right ventricular dilatation, segmental hypokinesia (mid-right ventricular) and hypercontractile right ventricular apex and overall right ventricular dysfunction...

Current evidence suggests that for outpatients with suspected pulmonary embolism (PE), multislice computed tomographic angiography (CTPA) is sufficient to rule out PE. However, the accuracy of CTPA alone has not been established for hospitalized patients. Our goal was to determine the prevalence of deep vein thrombosis (DVT) in hospitalized patients who had PE ruled out by CTPA. We conducted a prospective cohort study of patients who developed symptoms indicative of PE, after being admitted to the hospital for any reason other than PE and were evaluated with multislice CTPA...

Patients with pulmonary embolism (PE) present with highly variable clinical symptoms and often have accompanying comorbidities. Timely diagnosis and treatment are critical to help prevent recurrence and increased morbidity/mortality. While open surgical thrombectomy was once reserved only for those with massive PE and hemodynamic compromise, it has been reevaluated with a focus on careful patient selection and early intervention. Lately, there has been increased interest in catheter-based interventions and in combining these with an open surgical component to decrease the magnitude of the intervention-for example, direct placement of large-bore thrombectomy devices directly into the right ventricle via sternotomy or subxiphoid approaches...

This 16-year-old boy presented with acute retrosternal pain possibly representing acute myocardial infarction. Cardiac enzymes were within reference ranges. There were marked increases in metanephrine to 3299 μg/24 h (reference, <400 μg/24 h), normetanephrine to 1309 μg/24 h (reference, 0-390 μg/24 h), and chromogranin A to 1605 ng/mL (reference, 0-150 μg/24 h). An incidental left adrenal mass was found during CTPA performed to exclude pulmonary embolism. I-MIBG scintigraphy was negative, and genetic screening detected SDHB (succinate dehydrogenase syndrome subunit B) gene mutation...

Objective To assess the application of high-pitch CT pulmonary angiography (CTPA) at 70 kV tube voltage with 15 ml contrast medium using third-generation dual-source CT. Methods A total of 70 patients with clinically suspected pulmonary embolism were randomly divided into two groups: group A (n=35) underwent CTPA on conventional scanning mode (120 kV,80 ml contrast medium);and group B (n=35) underwent CTPA on high-pitch scanning mode at 70 kV tube voltage with 15 ml contrast medium. The CT values and standard deviations of the main pulmonary artery,apical segment of right upper pulmonary lobe (S1),and posterior basal segment of the right lower pulmonary lobe (S10),anterior thoracic air,and back muscles were measured...

The optimal approach to assess right ventricular (RV) function in patients with acute symptomatic pulmonary embolism (PE) lacks clarity. METHODS: This study aimed to evaluate the optimal approach to assess RV function in normotensive patients with acute symptomatic PE. Outcomes assessed through 30-days after the diagnosis of PE included all-cause mortality and complicated course. RESULTS: Eight hundred forty-eight patients were enrolled. Multidetector computed tomography (MDCT) and transthoracic echocardiography agreed on the presence or absence of RV overload in 449 (53%) patients...

Klippel-Trenaunay syndrome (KTS) is a congenital disorder characterized by venous malformations and a predisposition to pulmonary embolism. We reviewed the imaging findings of 7 adult patients with KTS who underwent thoracic CT. While the superficial manifestations of KTS predominantly affect the extremities, patients frequently develop abnormalities of the pulmonary arterial system, particularly chronic thromboembolic pulmonary hypertension. Additionally, some patients are seen to develop pulmonary arteriolar aneurysms; the physiologic significance of this finding is unknown at this time...

The pulmonary veins (PVs) are the most proximal source of arterial thromboembolism. Pulmonary vein thrombosis (PVT) is a rare but potentially lethal disease; its incidence is unclear, as most of the literature includes case reports. It most commonly occurs as a complica-tion of malignancy, post lung surgery, or atrial fibrillation and can be idiopathic in some cases. Most patients with PVT are commonly asymptomatic or have nonspecific symptoms such as cough, hemoptysis, and dyspnea from pulmonary edema or infarction...

Women are at increased risk of venous thromboembolism (VTE) during pregnancy and VTE remains one of the main causes of maternal mortality in developed countries (Konstantinides SV, et al. Eur Heart J 2014; 35(43):3033-69, 69a-69k). Although an accurate diagnosis of acute pulmonary embolism (PE) in pregnant patients is thus of crucial importance, the diagnostic management of suspected PE is challenging for this specific patient category. As D-dimer levels increase physiologically throughout pregnancy, the optimal D-dimer threshold to rule out PE during pregnancy remains unknown...

Venous thoracic outlet syndrome (vTOS) usually results from compression of the subclavian vein classically as a result of narrowing of the costoclavicular space. We report two rare cases of soft tissue neoplasms resulting in apparent vTOS. The first case is a 46-year old female with a two-year history intermittent unilateral shoulder pain, who was initially diagnosed with intervertebral disk herniation. Cervical fusion was performed, however her symptoms progressed and she additionally developed paresthesias and venous congestion...

Ectopic thyroid tissue is a rare entity and when discovered it is typically along the pathway of embryologic migration of the thyroid. We present a case of incidental finding of ectopic thyroid tissue within mediastinum in a 61-year-old female patient with a history of total thyroidectomy for thyroiditis and nodules. The patient presented to emergency room with cough and right chest pain and underwent a chest computed tomographic angiogram (CTA) to exclude pulmonary embolism as part of chest pain workup. One right paratracheal mediastinal soft tissue nodule was visualized on the images of CTA...

A 76-year-old woman, diagnosed 5 years previously with an asymptomatic mediastinal bronchogenic cyst, was referred to our department as the mass had grown slightly larger. Contrast-enhanced computed tomography and magnetic resonance imaging scans revealed an azygous vein aneurysm with a pulmonary arterial thromboembolism. The patient was treated with heparin for 5 days, and anticoagulation therapy with edoxaban was continued for 12 months. The thrombus resolved, and the aneurysm remained unchanged. An azygous vein aneurysm is a very rare condition that causes pulmonary arterial thromboembolism...

A 77-year-old man with a progressively dry cough (two months duration) was admitted with hemoptysis. Chest computed tomography (CT) revealed left lingular lobe consolidation and one thick-walled cavity lesion over the left lower lobe, which was accompanied by satellite micro-nodules in a tree-in-bud pattern. CT-guided biopsy confirmed mycobacterial infection, and subsequent culture yielded Mycobacterium avium complex (MAC). Unremitting hemoptysis was present despite treatment (14 days) with ethambutol, rifampin, clarithromycin, and streptomycin...
