Purpose: Chest radiography is normal in approximately 20-40% of acute pulmonary embolism (PE) patients without cardiopulmonary disease. The aim of this study was to determine whether there is any difference between the patients with normal chest X-ray and those with pathological findings in terms of clinical severity and prognosis. Methods: 178 of PE patients were included in the study. 110 patients had no parenchymal pathology, whereas group 1 (n = 110); group 2 (n = 68) had various pathological parenchymal findings in 68 patients. Clinical and radiological parameters were compared between these groups. Following the diagnosis of PE, the cases were recorded in the fifth year. Results: In 178 participants; those with normal chest X-ray (group 1), with parenchymal pathological findings on the chest X-ray (group 2); echocardiographic systolic pulmonary artery pressure (sPAP) (p = 0.68), gender (p = 0.9) and thrombus type (p = 0.41) were similar. The patients in group 1 were not different in terms of central thrombus detected in computed tomography pulmonary angiogram compared to the patients in group 2; however, the chest radiograph of the patients in group 1 had no parenchymal pathology. Central thrombus group 1, group 2, respectively; 97 (89.0%), 53 (77.9%), p = 0.07. There was no significant difference between the two groups in terms of mortality which was followed up in fifth year (p > 0.05). Conclusions: Normal chest X-ray in PE can determine mortality and may involve increased risk of massive PE. |
