We report the case of a 31-year-old female who was admitted to the emergency department with symptoms of cardiac arrest and ultimately died in spite of enormous resuscitation efforts. During resuscitation, pulmonary embolism was considered as a possible non-cardiac cause of cardiac arrest, and following its extremely unfavorable prognosis, the fatal outcome was not so surprising. However, since acute pulmonary emboli obstructing blood flow to a lobe or multiple lung segments was suspected, alteplase was indicated and administered...

Right ventricular (RV) myxomas are extremely rare, but may have dreadful clinical sequelae including pulmonary embolism (PE). We present a case of a patient who had an RV myxoma that was attached to the tricuspid valve, and therefore could not be resected completely during surgery, and remnants of the tumor were seen on transthoracic echocardiogram during post-operative follow-up. Five months after surgery, the patient had PE, which could be due to tumor emboli or thromboemboli. Since repeat surgical resection was not feasible, the patient was started on warfarin...

Introduction: Firearm-related injuries account for 20% of all injury-related deaths and are responsible for 105,000 injuries annually. The occurrence of bullet emboli to the heart is exceedingly rare. Given the rarity of emboli, controversy exists over management. The primary endpoint of this study is to establish a management algorithm for venous bullet emboli to the heart. Materials and methods: A literature search was performed using PubMed and Google Scholar with the following search terms: cardiac bullet embolus, cardiac missile embolus, and bullet embolus...

BACKGROUND: Heavy menstrual bleeding (HMB) is an important physical and social problem for women. Oral treatment for HMB includes antifibrinolytic drugs, which are designed to reduce bleeding by inhibiting clot-dissolving enzymes in the endometrium.Historically, there has been some concern that using the antifibrinolytic tranexamic acid (TXA) for HMB may increase the risk of venous thromboembolic disease. This is an umbrella term for deep venous thrombosis (blood clots in the blood vessels in the legs) and pulmonary emboli (blood clots in the blood vessels in the lungs)...

Paradoxical embolism due to isolated pulmonary arteriovenous malformation (AVM) is an uncommon cause of ischemic stroke, with the majority occurring in patients who have not yet been diagnosed with their malformation. We report a 32-year-old man who presented with an abrupt onset of right facial weakness and expressive aphasia. Brain magnetic resonance imaging revealed an acute infarct in the left middle cerebral artery territory and chronic infarcts in the bilateral cerebellar hemispheres. A cardioembolic mechanism was initially considered in the setting of perimyocarditis diagnosed a few months earlier...

Staphylococcus aureus is a common cause of bacteremia in the general population and can lead to serious metastatic infection particularly in immunocompromised persons. However, prompt diagnosis and management can result in favorable outcomes. In the following case report, the clinical course of an HIV-infected man is presented; he developed bloodstream infection (BSI) and associated complications: septic pulmonary embolism, right renal abscess, and ipsilateral renal vein thrombosis. Methicillin-resistant Staphylococcus aureus (MRSA) was identified as the cause of sepsis and successfully treated with surgery and antimicrobials...

INTRODUCTION: Acute pulmonary embolism is the third leading cause of cardiovascular death. Management options include anticoagulation with or without thrombolysis. Concurrent persistent hypoxemia should be a clue to the existence of an intracardiac shunt. CASE PRESENTATION: A 46-year-old man experienced acute hypoxemic respiratory failure requiring mechanical ventilation after anesthesia induction for elective hip arthroplasty. He was found to have submassive bilateral pulmonary emboli with acute right ventricular dysfunction and a coexisting patent foramen ovale with right-to-left shunt...

We herein describe a case of pulmonary tumor thrombotic microangiopathy (PTTM) with rapidly progressing colon cancer. A 61-year-old man who had been receiving treatment for type 2 diabetes mellitus for 3 years was hospitalized due to critical hypoxemia. Computed tomography, which had not shown any abnormalities 3 months previously, revealed a tumor in the ascending colon, multiple nodules in the liver, and the absence of any lung abnormalities. On day 3 of hospitalization, a sudden onset of severe dyspnea and tachycardia occurred, followed by death...

Radiological findings of pulmonary infarction have been well characterized mainly in established infarction. However, the early course CT appearance of patients who develop pulmonary infarction has not yet been fully elucidated. A 50-year-old female with a history of postmenopausal hormone replacement therapy (HRT) presented with dry cough and high-resolution computed tomography (HRCT) findings of fan-shaped segmental ground-glass opacity (GGO) in the right lower lobe. As the parenchymal density in the GGO gradually enlarged over a period of 4 weeks in spite of antibiotic treatment, the patient was referred to our hospital on clinical suspicion of bronchioloalveolar cell carcinoma...

Venous thromboembolism (deep vein thrombosis and pulmonary embolism) and bone cement implantation syndrome are major sources of embolic events in trauma patients. In these patients, embolic events due to venous thromboembolism and bone cement implantation syndrome have been detected with cardiac and vascular ultrasonography in the emergency setting, during the perioperative period, and in the intensive care unit. This article discusses the ultrasonography modalities and imaging findings of embolic events related to venous thromboembolism and bone cement implantation syndrome...

Occurrence of paradoxical arterial embolism may cause the first symptoms in patients with a coexisting hypercoagulable state and patent foramen ovale (PFO). This can result in significant morbidity and mortality depending on the location of the embolism. The risks and benefits of closure of small PFOs have not been well elucidated in prior studies. We describe a patient with a history of Factor V Leiden heterozygosity who presented with left arm pain secondary to arterial embolism. The patient was a 51-year-old male who initially presented to the emergency department after awaking from sleep with progressive, severe, burning left arm pain...

A 77-year-old Caucasian woman with recent abdominal surgery was diagnosed with multiple paradoxical systemic emboli in the mesenteric and renal circulation. Diagnosis was made by direct visualisation of a serpentine thrombus traversing both atria through patent foramen ovale (PFO) by transesophageal echocardiogram (TEE). Concomitantly, the patient was found to have deep venous thrombosis and pulmonary embolism. A decision was made to pursue cardiothoracic surgery preceded by inferior vena cava filter placement...

Paget-Schroetter syndrome, also known as effort thrombosis, is a relatively rare disease process characterized by primary thrombosis to the subclavian and axillary veins. It usually presents in younger individuals, commonly affecting the dominant side upper extremity, and the diagnosis relies on a combination of imaging, laboratory tests, and clinical presentation. Upper extremity deep vein thrombosis can also lead to pulmonary emboli, as in this case of a 20-year-old female discovered to have right sided Paget-Schroetter syndrome...

BACKGROUND: Contemporary mortality after bariatric surgery is low and has been decreasing over the past two decades. Most studies have reported inpatient or 30-day mortality, which may not represent the true risk of bariatric surgery. The objective of this study was to examine 1-year mortality and factors predictive of 1-year mortality after contemporary laparoscopic bariatric surgery. STUDY DESIGN: Using the 2008-2012 Bariatric Outcomes Longitudinal Database (BOLD), data from 158,606 operations were analyzed, including 128,349 (80...

Cavities are occasionally encountered on thoracic imaging. Their differential diagnosis is large and includes, among others, various infections, autoimmune conditions and primary and metastatic malignancies. We offer an algorithmic approach to their evaluation by initially excluding mimics of cavities then broadly classifying them according to the duration of clinical symptoms and radiological abnormalities.. An acute or subacute process (<12 weeks) suggests common bacterial and uncommon nocardial and fungal causes of pulmonary abscesses, necrotizing pneumonias, and septic emboli...
