Early diagnosis of pulmonary embolism after thoracic injury or surgery / 中国基层医药

Objective To evaluate experience for early diagnosis of pulmonary tembolism alter thoracic injury or surgery. Methods The 9 patients after thoracic injury or surgery with highly-suspected pulmonary embolism underwent chest radiograph of X-ray, helical CT pulmonary angiography, electrocardiogram, radionuclide pulmonary ventilation perfusion imaging, D dimer assay and arterial blood gas analysis respectively and the clinic data and results were analyzed. Results All patients were diagnosed and recovered after 8 patients received thrombolytic therapy and another patient received anticoagulant therapy. Conclusion If there were some symptoms such as suddenly severe dyspnea, cyanosis, with/without chest pains and the feeling of fear to death unable to be explained by original disease on those patients alter thoracic injury or surgery, it's very important for pulmonary embolism to be recognized, and early diagnosis and quickly efficient treatment is the key to prevent death. Helical CT pulmonary angiography is a safe, cheap, noninvasive and effective method for the diagnosis of pulmonary embolism with high sensitivity and specificity.

The value of diagnosis in pulmonary embolism by multislice spiral CT pulmonary angiography / 中国基层医药

Objective To evaluate the clinical value of pulmonary vessels with multi slice spiral CT pul-monary angiography(MSCTPA) in pulmonary embolism(PE). Methods MSCTPA was performed in 23 cases sus-pected patients. All the primitive images of pulmonary vessels were produced at the console workstation. The distri-bution of pulmonary vessels emboli was evaluated from different angle. Results Spatial relationship and anatomical details of pulmonary arteries and veins could exactly be shown on all pulmonary vessels three-dimensional images in above-mentioned patients. On the basis of MSCTPA, PE could be diagnosed definitely, in addition, collateral circula-tion formation could be clearly demonstrated. Of 23 patients, PE were found in 16 cases by MSCTPA. Two hun-drends and sixty-four emboli were demonstrated in total, among which there are 149 embolilocated in segmental ater-ies and 115 in subsegmental ateries(grade 5～6 branches). The minimal diameter of pulmonary atery with thrombus was 1mm. Conclusion MSCTA has very high clinical value in detecting segmental and aubsegrnental pulmonary thrombi in PE patients, and provides useful inforrnation for the diagnosis and treatment of pulmonary vascular dis-eases.
