Aim. To study effect of the level of vascular obstruction on the clinical manifestations of pulmonary embolism (PE). Material and methods. 63 patients with PE were included in this study. PE was verified by multidetector computed tomography (MSCT) with pulmonary angiography. 43 patients with high-risk PE survived the first week of the disease. In the remaining 20 patients with community-acquired pneumonia PE was diagnosed using MSCT pulmonary angiography in the first week of illness. Results. Obstruction of the trunk of the pulmonary artery or its lobar branches was detected in 34 (79.1%) patients with a high risk of PE and in only 2 (10%) ones with low-risk PE (p <0,001). The development of pneumonia complicated the course of the disease in 14 (32.6%) patients with a high risk of pulmonary embolism. The clots in the segmental branches of the pulmonary artery were identified in 9 (64.3%) patients with pneumonia. In high-risk patients with PE without pneumonia the lesion of segmental branches was detected only in 1 (3.4%) case (p <0,001). In patients with pneumonia at low risk of PE, the obstruction segmental branches was detected in 17 (85%) cases. Conclusion. The development of obstructive shock in PE is associated with a trunk embolism and/or the main pulmonary artery branches embolism. Infarction pneumonia is associated with the lesions of segmental branches of the pulmonary artery.
