BACKGROUND: Venous thromboemboli tend to recur. However, the causative factors underlying pulmonary embolism recurrence are not well defined. AIMS: To explore the factors associated with pulmonary embolism recurrence. PATIENTS AND METHODS: Patients diagnosed with pulmonary emboli between 2004 and 2013 at our institution were enrolled. Duration of anticoagulant therapy, new episodes of venous thromboembolism, and deaths were recorded. RESULTS: Pulmonary embolism was diagnosed in 528 patients (median age: 76 years, interquartile range [IQR]: 16; male: 45%)...

BACKGROUND: For some posterior inferior cerebellar artery (PICA) aneurysms, there is no constructive endovascular or direct surgical clipping option. Intracranial bypass is an alternative to a deconstructive technique. OBJECTIVE: To evaluate the clinical features, surgical techniques, and outcome of PICA aneurysms treated with bypass and obliteration of the diseased segment. METHODS: Retrospective review of PICA aneurysms treated via intracranial bypass was performed...

INTRODUCTION: The specific protein composition of stroke-causing emboli is unknown. Because ischemic stroke has a varied etiology, it is possible that the composition of the thrombus from which an embolus originated will have distinctive molecular characteristics reflective of the underlying pathophysiology. We used mass spectrometry to evaluate the protein composition of retrieved emboli from patients with differing stroke etiologies and correlated the protein levels to serum predictors of atherosclerosis...

We present a 65-year-old diabetic patient with a complex liver abscess and bacteraemia from Lactobacillus paracasei The abscess resulted in a prolonged hospital stay due to ongoing sepsis despite ultrasound-guided drainage and broad-spectrum antibiotics. Furthermore, the patient developed several secondary complications including a right-sided pleural effusion, an inferior vena cava thrombus and septic lung emboli. The abscess was eventually managed successfully with a prolonged course of antibiotics and multiple ultrasound-guided drainage procedures...

We report on a 34-yr-old male elite volleyball player with symptomatic emboli in the spiking hand from a partially thrombosed aneurysm of the posterior circumflex humeral artery (PCHA) in his dominant shoulder. At initial diagnosis and follow-up, a combination of time-resolved and high-resolution steady state contrast-enhanced magnetic resonance angiography (CE-MRA) enabled detailed visualization of: (1) emboli that were not detectable by vascular ultrasound; and (2) the PCHA aneurysm, including compression during abduction and external rotation (ABER provocation)...

Inflammatory breast cancer (IBC) is rare, but it is the most aggressive subtype of breast cancer. IBC has a unique presentation of diffuse tumor cell clusters called tumor emboli in the dermis of the chest wall that block lymph vessels causing a painful, erythematous, and edematous breast. Lack of effective therapeutic treatments has caused mortality rates of this cancer to reach 20%-30% in case of women with stage III-IV disease. Plasmonic nanoparticles, via photothermal ablation, are emerging as lead candidates in next-generation cancer treatment for site-specific cell death...

The ALARIS MSIII Infusion Pump (CareFusion, San Diego, CA) uses 3 separate alarms designed to prevent air emboli: "check air sensor," "air in lower tubing," and "air in line." It is assumed that ambient pressure changes cause air emboli that lead to pump failure although evidence to support this is limited. In this small study, the MSIII proved to be highly resilient and able to maintain function even after large repetitive emboli. Although unproven, it is more likely that these alarms are usually caused by loosening of the intravenous tubing within the pump's collar...

IMPORTANCE: Retinal artery occlusion (RAO) is a medical emergency associated with a high risk of cerebral vascular accident and other cardiovascular events. Among patients with non-arteritic RAO, a retinal embolus is observed in approximately 40% of cases. Fundus examination and retinography are not reliable to predict the nature of the emboli. OBSERVATIONS: We report three consecutive cases of central and branch RAO that were investigated with fundus autofluorescence, fluorescein angiography and color retinal photographs...

Choriocarcinoma is a highly malignant neoplasm arising from the trophoblast of a human pregnancy, which may have distant spread to multiple organs, particularly to the lung. We report a case of a pulmonary arteriovenous fistula that developed after chemotherapy within a choriocarcinoma metastasis. A 24-year-old female with a history of uterine choriocarcinoma presented with multiple hypervascular pulmonary nodules on the initial chest computed tomography (CT) scan, consistent with lung metastases. Four months after chemotherapy, follow-up chest CT revealed a decrease in the size and vascularity of the lung metastases, except for 1 nodule that persisted with marked contrast enhancement and developed a communication with a pulmonary artery and vein...

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rapidly progressive and often fatal pulmonary disease induced by tumor emboli within the small pulmonary arteries. PTTM presents clinically as progressive hypoxia and pulmonary hypertension. Most cases of PTTM are caused by an adenocarcinoma of the stomach. We present the first case report of PTTM caused by cervical squamous cell carcinoma. An 82-year-old woman presented with vaginal bleeding and exertional dyspnea. A cervical mass biopsy showed squamous cell carcinoma...

Staphylococcus aureus is able to disseminate from vascular device biofilms to the blood and organs, resulting in life-threatening infections such as endocarditis. The mechanisms behind spreading are largely unknown, especially how the bacterium escapes immune effectors and antibiotics in the process. Using an in vitro catheter infection model, we studied S. aureus biofilm growth, late-stage dispersal, and reattachment to downstream endothelial cell layers. The ability of the released biofilm material to resist host response and disseminate in vivo was furthermore studied in whole blood- and phagocyte survival assays, and in a short-term murine infection model...

In the setting of blunt trauma, the rapid assessment of internal injuries is essential to prevent potentially fatal outcomes. Computed tomography is a useful diagnostic tool for both screening and diagnosis. In addition to trauma, acute chest syndromes often warrant emergent computed tomographic angiography, looking for etiologies such as aortic aneurysms or complications of aortic aneurysms, or both, pulmonary emboli, as well as other acute vascular process like aortic dissection and Takayasu aortitis. With continued improvements in diagnostic imaging, computed tomographic angiography of the chest, abdominal and pelvis proves to be an effective modality to image the aorta and other major vascular structures...

INTRODUCTION: Endovascular aneurysm repair (EVAR) is the most commonly used approach for treatment of abdominal aortic aneurysms (AAA). Testicular infarction is a rare complication of EVAR. A novel case of acute global testicular infarction post-EVAR from cholesterol embolisation mimicking torsion is presented. REPORT: A 75 year old man developed acute right testicular ischaemia requiring orchidectomy following EVAR of an infrarenal aortic aneurysm. The patient was initially diagnosed with testicular torsion as the aetiology of the infarction; however, on re-analysis of histopathology it was found to be secondary to cholesterol emboli...

OBJECTIVE/BACKGROUND: This report presents a superior mesenteric artery (SMA) embolism managed by percutaneous mechanical thrombectomy (PMT). METHODS: A 61 year old woman diagnosed with SMA embolism was admitted. Emboli were found in the middle and distal segments of the SMA on abdominal computed tomography angiography. Under local anaesthesia, a 6 F Rotarex system was used to remove the emboli via left brachial artery access. Emboli were successfully removed and patency was restored to the SMA and its branches...

A 44-year-old woman presented with marked erythema over right mastectomy scar, while on Herceptin therapy. She had neoadjuvant chemotherapy, modified radical mastectomy, and radiotherapy less than one year earlier for the treatment of invasive ductal carcinoma. On physical examination, no palpable masses were detected in the erythematous skin. A biopsy revealed permeation of the skin lymphatics by emboli of metastatic ductal carcinoma, similar to what is seen in inflammatory carcinoma. The involved skin was excised, followed by immediate reconstruction with transverse rectus abdominis muscle (TRAM) flap...

BACKGROUND Pulmonary arterial hypertension (PAH) results from proliferative vasculopathy involving all layers of the blood vessel. Similar findings may be present in pulmonary hypertension (PH) associated with microscopic tumor embolism, which are thought to be related to the phenomenon of pulmonary tumor thrombotic microangiopathy (PTTM). PTTM is associated with the activation of the coagulation system at the surface of the tumor emboli, resulting in stenosis or occlusion of the vessel. CASE REPORT A 49-year-old man with stage IV gastro-esophageal junction adenocarcinoma presented with complaints of cough and shortness of breath...

BACKGROUND: DNA methylation changes occurring in cancer cells are featured with both promoter CpG island hypermethylation and diffuse genomic hypomethylation. Long interspersed element-1 (LINE-1) is repeated in an interspersed manner with an estimated 500,000 copies per genome. LINE-1 has its CpG sites of the 5' untranslated region methylated heavily in normal cells and undergoes demethylation in association with cancerization. However, little information is available regarding LINE-1 hypomethylation and its prognostic implication in intrahepatic cholangiocarcinomas...
