Two patients with liver cirrhosis and portal hypertension related to hepatitis infection were admitted to Shanghai Ruijin Hospital due to recurrent melena and hematemesis. Isolated gastric varices were observed in the gastric fundus during the retroflexion of gastroscope. We carried out endoscopic sclerotherapy successfully for bleeding gastric varices with combined cyanoacrylate and aethoxyskl...

Known commonly as "broken heart syndrome," takotsubo cardiomyopathy is a poorly understood heart condition that results in acute decompensation of cardiac function. We report a case of a 68-year-old female who developed acute shortness of breath status after chemotherapy and radiation treatment for Stage IV squamous-cell carcinoma. Computed tomography pulmonary angiogram (CTPA) revealed a singl...

In spite of high incidence pulmonary embolism (PE), its diagnosis can be challenging due to vagaries symptoms. Conversely, right shoulder pain is a relatively easy clinical presentation which mostly musculoskeletal in nature. But only case PE, has proven difficult correlation make. We here describe patient with no prior history DVT or prolonged bed rest recent surgery but admitted emergency dep...

The authors are developing a computerized pulmonary vessel segmentation method for a computer-aided pulmonary embolism (PE) detection system on computed tomographic pulmonary angiography (CTPA) images. Because PE only occurs inside pulmonary arteries, an automatic and accurate segmentation of the pulmonary vessels in 3D CTPA images is an essential step for the PE CAD system. To segment the pulm...

We describe an 81-year-old man presenting to the emergency department with an unwitnessed syncope. All initial examinations and investigations were non-diagnostic. He was admitted for observation, during which he developed type 1 respiratory failure and mild fever. Computerised tomography of pulmonary angiography (CTPA) was carried out to rule out pulmonary embolism. This revealed a foreign bod...

The purpose of this research was to study the neutralization efficacy of a universal neutralizer proposed by the CTPA on a range of antimicrobial agents and its potential toxicity for microorganisms that are used for antimicrobial preservation testing. Several types of antimicrobial agents including a mixture of methylisothiazolinone and its 5-chloro derivative, dimethylol dimethyl hydantoin, Q...

partial volume), or disease-related.3 Disease-related artefacts have been reported to include impacted mucus in the bronchi, perivascular edema, or pulmonary artery sarcoma. However, as far as we are aware, this is the first description of structural changes (such as presented by our 2 patient) causing anatomical distortion of the pulmonary arteries, that in turn produced intravascular turbulen...
