BACKGROUND: Superior vena cava (SVC) syndrome is a major complication that occurs when a growing lung malignancy compresses the SVC extrinsically. Current treatment options include radiotherapy or chemotherapy to shrink the tumor or endovascular stenting of the SVC to restore flow. Herein, we report a case series treated in a single institution to demonstrate the safety, effectiveness, and outcomes of salvage and primary stenting for malignant SVC obstruction. METHODS: A total of 12 male patients with malignant superior vena cava obstruction caused by lung cancer underwent SVC stenting from October 2009 to May 2015...

We present a case of a 54-year-old patient with cirrhosis, progressive dyspnea, and platypnea. Thoracic computed tomography (CT) showed multiple pulmonary arteriovenous malformations (PAVM), confirming the diagnosis of hepatopulmonary syndrome (HPS). Besides precisely identifying the number and location of PAVM, CT also demonstrated a striking mosaic pattern of the lung parenchyma, characterized by the presence of alternating geographic areas of low attenuation (showing pulmonary vessels with a decreased diameter) with regions of relatively increased attenuation (showing pulmonary vessels with a normal diameter)...

PURPOSE: Iliac vein compression is a known culprit of deep vein thrombosis (DVT). In contrast, the compression may prevent the pulmonary embolism (PE). The aim of this study was to evaluate the anatomic and clinical risk factors of PE in patients with lower extremity DVT. METHODS: PE was evaluated using chest computed tomography in patients with lower extremity DVT. The patients were classified into group I (DVT without PE) and group II (DVT with PE) and analyzed to clarify the anatomic and clinical risk factors associated with PE in patients with DVT...

Pulmonary embolism (PE) remains a common and important clinical condition that cannot be accurately diagnosed on the basis of signs, symptoms, and history alone. The diagnosis of PE has been facilitated by technical advancements and multidetector CT pulmonary angiography, which is the major diagnostic modality currently used. Ventilation and perfusion scans remain largely accurate and useful in certain settings. Lower-extremity ultrasound can substitute by demonstrating deep vein thrombosis; however, if negative, further studies to exclude PE are indicated...

Non-invasive imaging modalities integrate the clinical and laboratory diagnostic work-up of patients admitted in emergency department for chest pain. Transthoracic echocardiography is the first-line imaging tool because it is rapidly and widely available, bedside feasible and cost-effective. Even when a comprensive exam is not feasible, a fast focused ultrasound exam should be performed. Contrast enhanced computed tomography is an easily accessible tool with specific application in patients suspected for pulmonary embolism (PE) and acute coronary syndrome (ACS) according to the pre-test risk assessment and to the clinical status...

Detection of right heart thrombi (RHT) in the context of pulmonary thromboembolism (PE) is uncommon (4-18%) and increases the risk of mortality beyond the presence of PE alone. Type A thrombi are serpiginous and highly mobile and are thought to be originated from large veins and captured in-transit within the right heart. Optimal management of RHT is still uncertain. A 79-year-old woman, with a history of recent total hysterectomy with adnexectomy and a Wells procedure, presented to the emergency department following an episode of syncope...

A 65-year-old woman with no significant medical history visited the emergency department complaining of epigastric discomfort. A computed tomography of the thorax and abdomen showed the attenuation of the pulmonary artery and a posterior mediastinal hematoma. Angiography showed a tortuous esophageal branch of the left gastric artery and a pseudoaneurysm, and during the later phase, the left lower lobe of the lung was enhanced, and finally, the left pulmonary vein was enhanced. We considered that the patient was exhibiting hypoperfusion of the left pulmonary artery arising from left pulmonary artery hypoplasia, since the left lung was supplying the systemic circulation...

Intimal sarcoma of the pulmonary artery is rare, but false diagnosis of this sarcoma as pulmonary embolism is not infrequent. The present study reports a case of pulmonary artery intimal sarcoma misdiagnosed as pulmonary artery embolism in a 37-year-old female patient. The patient was admitted to the cardiac intensive care unit of Guangdong General Hospital (Guangzhou, China) with the complaint of progressive exertional dyspnea over the past two years. Multi-slice spiral computed tomography, transthoracic echocardiography, right-heart catheterization and cardiac magnetic resonance imaging revealed mimicking severe pulmonary embolism in the pulmonary trunk and right pulmonary artery, with symptoms including chest pain, cough and breathing difficulties...

OBJECTIVES: Pulmonary embolism (PE) is seven times more common in cancer patients than non-cancer patients. Since the existing clinical prediction rules (CPRs) were validated predominantly in a non-cancer population, we decided to look at the utility of arterial blood gas (ABG) analysis and D-dimer in predicting PE in cancer patients. METHODS: Electronic medical records were reviewed between December 2005 and November 2010. A total of 177 computed tomography pulmonary angiograms (CTPAs) were performed...

Progress in pharmaceutical development is highly-dependent on preclinical in vivo animal studies. Small animal imaging is invaluable for the identification of new disease markers and the evaluation of drug efficacy. Here, we report for the first time the use of a three-dimensional fluorescence bioimager called FLuorescence Emission Computed Tomography (FLECT) for the detection of a novel recombinant fluoroprobe that is safe, easily prepared on a large scale and stably stored prior to scan. This novel fluoroprobe (Targ-Cy7) comprises a single-chain antibody-fragment (scFvTarg), which binds exclusively to activated-platelets, conjugated to a near-infrared (NIR) dye, Cy7, for detection...
