Association between Main Pulmonary Artery Diameter and COVID-19 Severity- A Cross-sectional Study

Introduction: Long-term consequences of the Coronavirus Disease 2019 (COVID-19) pneumonia infection, like lung vessel thrombosis and pulmonary hypertension, require prompt diagnosis management. Hence, measurement Main Pulmonary Artery Diameter (MPAD) in patients with moderate to severe Computed Tomography (CT)-based severity scoring helps detect possibility complication early. In this study, Reporting Data System (CO-RADS) for suspected were done. Aim: To measure MPAD Reverse Transcription-Polymerase Chain Reaction (RT-PCR) COVID-19 positive (CO-RADS 6) highly suspicious (CO- RADS 4, 5) then associate CT Severity Score (CTSS). Materials Methods: This cross-sectional, retrospective study was conducted Department Radiodiagnosis, Father Muller Medical College, Mangalore from January 2020 2022. Total 200 patients, including 141 males 59 females, who studied. findings noted, CTSS calculated. used categorise sample into mild, moderate, categories. measured corresponding patients. The associated using Chi-square test, p-value<0.05 considered significant. Results: Considering various parameters age, gender, co- morbidities, MPAD, there no statistically significant association between former three parameters. 72 92 36 cases. found a co-morbidities (p-value=0.009) (p-value=0.024). Conclusion: could be predict future complications artery hypertension pneumonia.
