Incidence du coeur pulmonaire aigu et de la thrombose veineuse profonde dans l'embolie pulmonaire aiguë [Incidence of acute cor pulmonale and deep venous thrombosis in acute pulmonary embolism]

OBJECTIVE: Ultrasounds are a useful tool when looking for indirect evidence in favor of pulmonary embolism. The aim of this study was to determine the incidence of acute cor pulmonale and deep venous thrombosis revealed by ultrasonographic techniques in a population of patients presenting with pulmonary embolism. METHODS: 96 consecutive patients with a mean (+/- SD) age of 65 +/- 15 years, admitted to our hospital for pulmonary embolism were included in this study. The diagnosis of pulmonary embolism was made either by spiral computed tomography or selective pulmonary angiography. Each patient subsequently underwent both trans-thoracic echocardiography and venous ultrasonography. The diagnostic criterion used for defining acute cor pulmonale by echocardiography was the right to left ventricular end-diastolic area ratio over (or equal to) 0.6. Diagnosis of deep venous thrombosis was supported by the visualization of thrombi or vein incompressibility and/or the absence of venous flow or loss of flow variability by venous ultrasonography. RESULTS: Using ultrasounds, an acute cor pulmonale was found in 63% of our patients while 79% were found to have deep venous thrombosis and 92% of the patients had either acute cor pulmonale or deep venous thrombosis or both. All of the patients with proximal pulmonary embolism had acute cor pulmonale and/or deep venous thrombosis. The presence of acute cor pulmonale on echocardiography was significantly higher in patients with proximal pulmonary embolism (p < 0.0001). CONCLUSION: This study emphasizes the potential value of ultrasonographic techniques in the diagnosis of acute pulmonary embolism.

Fissures du labrum glénoïdal postérieur et lésions associées de l'épaule: une étude en arthroscanner [Fissures of the posterior labrum and associated lesions: CT arthrogram evaluation]

PURPOSE: To describe osseous, chondral and tendinous lesions associated with fissures of the posterior labrum. To better understand the pathological processes leading to fissure of the posterior labrum. Materials and methods. Retrospective study of 43 CT arthrograms performed in 43 patients that showed a fissure of the posterior labrum. The following associated lesions were noted: osseous and chondral remodeling of the humeral head and/or glenoid and articular surface fissures of the rotator cuff. Based on type of associated lesions, patients were separated into one of four pathological subgroups: posterior instability, posterosuperior or internal impingement, anterior instability and isolated fissure of the posterior labrum. RESULTS: Sixteen patients (37.2%) of patients showed posterior instability, 12 (27.9%) showed lesions of internal impingement, and 11 (25.6%) showed lesions of anterior instability. Only 4 patients (9.3%) had an isolated fissure of the posterior labrum. CONCLUSION: Posterior instability, internal impingement and anterior instability are the main pathologies leading to fissure of the posterior labrum, which seldom occurs in isolation. Evaluation of these associated lesions allows understanding of the underlying pathological processes leading to fissure of the posterior labrum.
