The aim of the present study was to investigate the characteristics and value of 3D dynamic contrast-enhanced magnetic resonance pulmonary angiography (3D-DCE-MRPA) for the diagnosis of pulmonary embolism (PE). Among patients suspected with PE, 30 cases were scheduled for 3D-DCE-MRPA [magnetic resonance imaging (MRI) group], and 30 cases were examined using multislice computed tomographic pulmonary angiography (msCTPA) [computed tomography (CT) group]. Direct signs including location, number, morphology of emboli, and indirect signs such as pulmonary infarction, pneumonia and pleural effusion, were analyzed. Pulmonary artery enhancement was observed. Image quality was contrasted, branches of the pulmonary artery revealed, and differences in sensitivity, specificity and signal-to-noise ratio (SNR) were compared. The number and morphology of emboli in the two groups were compared, and there were no significant differences (P>0.05). In the MRI group, significantly more emboli were located in segmental and subsegmental bronchi (P<0.05). The indirect signs in the two groups were compared and the differences were not statistically significant (P>0.05). The difference in image quality between the two groups was not statistically significant (P>0.05). Levels 5 and 6 of the pulmonary artery branch were more evident in the MRI group compared to the CT group. The SNR and carrier-to-noise ratio in the MRI group were significantly higher than those in the CT group (P<0.05). Twenty-six cases of PE were diagnosed in the CT group, with a sensitivity of 90.5% and specificity of 86.7%. Twenty-five cases were diagnosed in the MRI group, with a sensitivity of 92.3% and specificity of 84.2%. In conclusion, 3D-DCE-MRPA surpassed msCTPA in revealing segmental and subsegmental pulmonary artery PE.
- Spontaneous right whole-lung torsion secondary to bronchial carcinoma: a case report. [Journal Article]
- J Cardiothorac Surg 2016; 11(1):107JC
- CONCLUSIONS: To our knowledge this is the first reported case of a patient presenting with lung torsion as the first symptom of lung cancer. When lung torsion is suspected rapid diagnosis is crucial in order to prevent hemorrhagic lung infarction.

Left ventricular pseudoaneurysm is a rare complication of acute myocardial infarction, associated with high mortality. However, it can present in a non-specific manner, complicating and delaying the diagnosis. The authors present the case of a 65-year-old patient, hypertensive, with no other known relevant medical history, who presented with chest pain, cough and left pleural effusion, initially attributed to a pulmonary process. However, these were in fact the result of a left ventricular pseudoaneurysm following silent acute myocardial infarction. The diagnosis was suspected on echocardiography and confirmed by cardiac magnetic resonance imaging, and the patient underwent successful surgical pseudoaneurysm repair. This case illustrates an atypical presentation of a left ventricular pseudoaneurysm, in which the manifestations resulted from pericardial and pleural extension of the inflammatory process associated with contained myocardial rupture. The case demonstrates the need for a high index of suspicion, and the value of imaging techniques to confirm it, in order to proceed with appropriate surgical treatment, and thus modify the course of the disease.
- A massive haemothorax as an unusual complication of infective endocarditis caused by Streptococcus sanguinis. [Journal Article]
- Acta Clin Belg 2016; 71(4):253-7AC
- CONCLUSIONS: When treating infective endocarditis caused by S. sanguinis, clinicians should include haemothorax in the differential diagnosis of patients complaining of sudden chest pain.

Objective The aim of the study was to analyze respiratory system function after minimally invasive aortic valve replacement through right anterior minithoracotomy (RAT-AVR). Methods An observational study of 187 patients electively scheduled for RAT-AVR between January 2010 and December 2013. Pulmonary complications were analyzed and spirometry examinations were performed preoperatively, 1 week, 1 month, and 3 months after surgery. Results Hospital mortality was 1.1%. A double-lumen intratracheal tube was used in 88.2% and single-lumen intratracheal tube was used in 11.8% of patients. Pulmonary complications occurred in 10.8% of the patients. Prolonged (>24 hours) mechanical ventilation time was present in five patients (2.7%). The reasons were stroke (n = 1), perioperative myocardial infarction (n = 2), and pneumothorax (n = 2). Right pleural effusion, which occurred in 7.7% (n = 14) of patients, was the most frequent respiratory system complication. One week after surgery, the spirometry parameters decreased in comparison to the preoperative period, then after 3 months statistically significant improvement occurred; however, the spirometry parameters still had not returned to preoperative values. Multivariable median regression analysis shows that the presence of chronic obstructive pulmonary disease and pulmonary complications were associated with lower values of forced expiratory volume in 1 second after surgery. There was no statistically significant difference regarding spirometry values or incidence of pulmonary complications after surgery between patients in whom single-lung or double-lung ventilation was applied. Conclusion Pulmonary functional status measured with spirometry parameters was diminished after RAT-AVR surgery. Single-lung ventilation did not result in a higher rate of respiratory complications after RAT-AVR surgery.
- The prognostic significance of serum troponin T levels in Crimean-Congo Hemorrhagic Fever patients. [Journal Article]
- J Med Virol 2015 Dec 22JM
- CONCLUSIONS: An increased troponin T level may be a prognostic risk factor for hemorrhage in CCHF patients. This marker should therefore be borne in mind in determining treatment strategy in these patients. This article is protected by copyright. All rights reserved.

We describe the case of a 23-year-old man presenting with recurrent pleuritic chest pain and prolonged fever after electrophysiology testing and placement of an implantable cardioverter-defibrillator because of a suspected arrhythmogenic right ventricular dysplasia. The clinical suspicion was initially directed toward pneumonia with pleural effusion and later toward an infection of the cardiac device complicated by septic pulmonary embolism. The definitive diagnosis of pulmonary embolism and infarction was suggested by a point-of-care thoracic sonography, performed at the bedside by a clinician caring for the patient, and then confirmed by contrast enhanced computed tomography, which also showed thrombosis of the left iliofemoral vein, site of percutaneous puncture for cardiac catheterization. Prolonged fever was attributable to a concomitant Epstein-Barr virus primary infection that acted as confounding factor. The present report confirms the value of bedside thoracic sonography in the diagnostic evaluation of patients with nonspecific respiratory symptoms.
- Pulmonary manifestations in a group of patients with Behcet's disease. [Journal Article]
- Int J Rheum Dis 2015 Sep 9IJ
- CONCLUSIONS: The higher frequency of pulmonary manifestations in our patients (73.3%) and the higher frequency of PAA (33.3%) could be related to the fact that this study was conducted on a group of patients who were admitted to the hospital with more severe illnesses.
- Frequency of nonthromboembolic imaging abnormalities in pregnant women referred for computed tomography pulmonary arteriography. [Journal Article]
- Can Assoc Radiol J 2015; 66(1):24-9CA
- CONCLUSIONS: Pulmonary embolism occurs in 5% of pregnant women referred for CTPA. In pregnant women without embolism on CTPA, potential alternative causes for patient symptoms are seen on CT in 12% of cases.

- Detailed statistical analysis plan for the pulmonary protection trial. [Randomized Controlled Trial]
- Trials 2014; 15:510T
- CONCLUSIONS: The pulmonary protection trial investigates the effect of pulmonary perfusion during cardiopulmonary bypass in chronic obstructive pulmonary disease patients. A preserved oxygenation index following pulmonary perfusion may indicate an effect and inspire to a multicenter confirmatory trial to assess a more clinically relevant outcome.
