BACKGROUND: Percutaneous vertebroplasty (PV) has recently become a very common procedure for vertebral compression fractures. Extravasation of cement, a common event associated with vertebroplasty, may lead to cement emboli in the lungs. PURPOSE: To determine the frequency of pulmonary cement embolism after percutaneous vertebroplasty. MATERIAL AND METHODS: Between 2002 and ...

Selection of patients for diagnostic tests for acute pulmonary embolism requires recognition of the possibility of pulmonary embolism on the basis of the clinical characteristics. Patients in the Prospective Investigation of Pulmonary Embolism Diagnosis II had a broad spectrum of severity, which permits an evaluation of the subtle characteristics of ...

A 78-year-old man was admitted with sudden onset of dyspnea followed by syncope. Contrast-enhanced computed tomography showed embolism in the right main pulmonary artery and left upper pulmonary artery. Echocardiography revealed a large, free-floating thrombus and cine magnetic resonance imaging showed highly mobile, low-signal intensity mass in the right atrium, ...

Fat embolism syndrome (FES) is a common complication of fractures, usually of the long bones and pelvis. Common computed tomography findings of pulmonary FES include areas of consolidation, ground-glass opacities, and small nodules of various sizes, whereas filling defects in pulmonary arteries are rarely described in nonfulminant syndromes. We present ...

BACKGROUND: Pulmonary embolism (PE) is a common condition, but the diagnostic strategy for the evaluation of suspected PE is somewhat controversial. Despite the use of various biochemical markers (such as D-dimer and C-reactive protein) and various probability calculation algorithms based on clinical findings for that purpose, there is still a ...

Use of a very low probability interpretation of ventilation/perfusion (V/Q) lung scans, if verified by prospective evaluation to have a low positive predictive value (PPV), will reduce the number of nondiagnostic interpretations of V/Q scans and may be particularly useful in patients with a relative contraindication to CT. The purpose ...

The aim of the present study was to assess the safety and implementation of a diagnostic strategy in hospitalised patients with suspected acute pulmonary embolism (PE). A diagnostic strategy was established and implemented in a general hospital. A retrospective cohort study, including 400 consecutive in-patients, was performed in order to ...

The presence of right heart thrombi appears to increase the risk of mortality compared to the presence of pulmonary thromboemboli alone. The increased use of two-dimensional echocardiography has led to increased detection of these thromboemboli, particularly in patients with suspected or confirmed pulmonary emboli. The optimal management of the right ...

Achilles tendon injury is common and surgical procedures related to it are frequently performed and are safe. The incidence of acute pulmonary embolism following these procedures is extremely rare. This case illustrates an incidence of acute pulmonary embolism following Achilles tendon repair in a 35-year-old woman. We discuss the possible ...

We present the case of a 61-year-old male patient with chronic obstructive pulmonary disease and a large cervicomediastinal multinodular hyperfunctioning goiter that made thyroidectomy a daunting task, especially considering the risk of intraoperative bleeding. The preoperative computed tomographic (CT) scan showed the right thyroid lobe very deeply rooted in the ...

Percutaneous vertebroplasty consists of injection of acrylic cement - polymethylmethacrylate - into a vertebral body to obtain pain relief and increase its mechanical stability. The procedure is indicated for painful hemangiomas and for painful vertebral compression fractures due to osteoporosis or malignancy. Although vertebroplasty is an efficient treatment, it is ...

Pulmonary embolism is a potentially fatal disease in which early recognition and institution of anticoagulant treatment can prevent mortality. The diagnostic tools available to establish whether a patient has a pulmonary embolism were limited to pulmonary angiography and ventilation-perfusion scintigraphy. Both tests have considerable limitations. Helical CT evolved as a ...

Fatal embolic chondroblastic osteosarcoma to the lung is an extremely rare phenomenon. We report a case of a 15-year-old boy who developed bilateral pulmonary embolism shortly after resection of the right distal femur for chondroblastic osteosarcoma. The patient succumbed to right-sided heart failure 8 weeks later. An autopsy revealed extensive ...

BACKGROUND AND PURPOSE: Most cement leaks during vertebroplasty are asymptomatic, but pulmonary cement embolism has been reported to cause cardiovascular disturbances and even death. Adding hydroxyapatite (HA) to polymethylmethacrylate (PMMA) cement to reduce the quantity of barium may aggravate cardiovascular deterioration in the event of cement embolism by activating coagulation. ...

Massive pulmonary embolism is a life-threatening condition to be treated with anticoagulants or even thrombolytic agents in selected cases. However, these drugs are controindicated after a recent hemorrhagic episode. We report the case of a 46-year-old patient with uncontrolled systemic hypertension who was affected by severe spontaneous cerebral hemorrhage and ...

Venous thromboembolic disease is composed of two disease entities: pulmonary thromboembolism/pulmonary embolism and deep venous thrombosis. Clinical signs and symptoms of venous thromboembolic disease often are nonspecific and, as a result, the diagnosis may be difficult. If left untreated, pulmonary embolism can lead to a potentially fatal outcome. This article ...

Pulmonary embolism represents a major public healthcare problem and it also imposes frequent clinical diagnostic issues. Despite the availability of the D-dimer tests, imaging remains the mainstay for its diagnosis. Computed tomography pulmonary angiography (CTPA) is now the most widely used diagnostic test and its utility has been well validated ...

Acute pulmonary embolism (PE) is a common, serious and potentially fatal event. Due to the serious nature of this ailment and since therapy is usually with long-term anticoagulation, it is important for the clinician to be able to diagnose or exclude acute PE. Several diagnostic options are available to the ...

Pulmonary embolism (PE) is a very serious condition causing sudden death in about one-third of the cases. Treatment with anti-clotting medications is highly effective but not without complications, while diagnosis has been missed in about 70% of the cases. A major clinical challenge, particularly in an Emergency Room, is to ...

Primary pulmonary artery leiomyosarcomas are rare, and the diagnosis is usually confused with other, more common, diseases, especially pulmonary embolism. A 52-year-old male, previously healthy, sustained a cardiac arrest. Chest CT-angiography diagnosed a "saddle embolus". Local thrombolysis was tried without any obvious success. At this point, the possibility of neoplasm ...
