Abstract
Aim: To evaluate whether pulmonary artery size is indicator of pulmonary hypertension in patients with interstitial lung disease.Objective: To measure main pulmonary artery size in interstitial lung disease on CT. To compare these measurements with 2Decho findings in diagnosing the pulmonary hypertension.Materials and Methods Type of study: Prospective studyDuration of study: 1st June 2021 to 1st September 2022 Results and Conclusion: 30 patients with interstitial lung disease with suspicion of pulmonary hypertension were subjected to CT scan Among the 22 patients with dilated pulmonary artery, 64% were found to show signs of probable pulmonary hypertension on 2DEcho and remaining 36% patients were found to be negative.In the remaining 8 patients who were not having dilated pulmonary artery, only one patient showed signs of pulmonary hypertension on 2 Decho. Dilated pulmonary artery was correlated positively with 2Decho findings in pearson correlation of coefficient.Thus, dilated pulmonary artery can raise a suspicion of pulmonary hypertension in interstitial lung diseases. Therefore, pulmonary artery diameter is key for screening of suspected pulmonary hypertension
