BACKGROUND Hyperdense middle cerebral artery sign is an appearance of the middle cerebral artery on non-contrast-enhanced computed tomography. Embolic occlusion of the pulmonary arterial system is referred to as pulmonary embolism. When pulmonary embolism coexists with a patent foramen ovale, increased pressure in the right atrium may result in widening of the foramen and consequently, cause se...

The objective of this case study is to discuss a rare case of proven paradoxical thromboembolism captured in-transit. A 23-year-old female with a diagnosis of right internal jugular deep vein thrombus who developed acute onset chest pain, dyspnea and hypotension, was selected for the study. Sub-massive PE and STEMI were diagnosed. Transthoracic echocardiogram revealed a left ventricular (LV) ma...

background: pregnancy causes a small increase in risk of venous thromboembolism (vte), but a large increase in concern upon presentation during cesarean section with symptoms of pulmonary embolism (pe). pulmonary embolism clinical manifestations during spinal anesthesia could be misleading. we have presented 2 interesting cases of pregnant women underwent spinal anesthesia for cesarean section ...

A 21-year-old female patient was transferred to our hospital after being diagnosed with massive pulmonary thromboembolism (PTE). Three years prior to admission, she underwent transcatheter closure of the secundum ASD with a 33 mm CardioSEAL-StarFLEX occluder (NMT Medical, Boston, MA, USA). A year ago, she was involved in a car accident and sustained significant blunt chest trauma. Transthoracic...

Pulmonary thromboembolism is a very rare event in children, but the mortality rate is reported to be approximately 10%. The majority of children with thromboemboli have multiple risk factors, such as a catheter-related thrombosis, an infection, and a congenital prothrombotic disorder. Hypereosinophilia is very rarely associated with pulmonary emboli in adults; however, this condition has not be...

The risk of venous thromboembolic complications among pregnant women and puerperas is higher than in the general population, which due to traditional factors, as well physiological anatomical changes that occur during pregnancy. Symptoms signs pregnancy are often nonspecific may coincide with consequences changes, including dyspnea, limb edema, tachycardia. D-dimer levels be elevated ongoing pr...

OBJECTIVE To estimate the incidence and determine the characteristic features of venous thromboembolism in the Hong Kong Chinese population. DESIGN Retrospective study. SETTING Regional hospital, Hong Kong. SUBJECTS AND METHODS Data were collected during a period of four years (1997-2000). Patients with duplex doppler ultrasonography or venography-documented venous thromboembolism and new...

The main goal of this report was to share with clinicians an atypical presentation of pulmonary thromboembolism (PTE) in a young male`s post-appendectomy, whom he had no significant predisposing factors for such disease. The case also introduced for re-examining the challenges of PTE clinical manifestations which may mimic other differential diagnosis. PTE is an abrupt blockage of the pulmonary...

Pulmonary thromboembolism is a common condition. Its diagnosis usually requires pulmonary scintigraphy, computed angiotomography, pulmonary arteriography and, in order to rule out other diagnoses, the measurement of D-dimer levels. Due to the fact that these diagnostic methods are not available in most Brazilian hospitals, the validation of other diagnostic techniques is of fundamental importan...

Treatment goals for deep venous thrombosis include stopping clot propagation and preventing the recurrence of thrombus, the occurrence of pulmonary embolism, and the development of pulmonary hypertension, which can be a complication of multiple recurrent pulmonary emboli. About 30 percent of patients with deep venous thrombosis or pulmonary embolism have a thrombophilia. An extensive evaluation...
