Correlation of Pulmonary Embolism Severity Index and Pulmonary Artery Involvement in Ct Pulmonary Angiogram- Experience in a Tertiary Care Centre

BACKGROUND embolism is a common and life-threatening condition. Most of the mortality due to pulmonary embolism occurs the first few hours of the event. Despite improvement in diagnostic techniques, delays in diagnosis of pulmonary embolism common. As an aetiology of sudden death, massive pulmonary embolism is second only to sudden cardiac death. In current , it is underdiagnosed. Even though, the diagnosis is established, the choice of treatment decides the prognosis. So, PESI (pulmonary embolism severity index), we can categorise patients into low-risk group and high-risk group and it with CTPA (computed tomography pulmonary angiogram) imaging for level of pulmonary artery involvement. AND METHODS is a retrospective study for a period of 3 years from January 2013 to June 2016. Total of 50 patients were included in this . In acute pulmonary embolism, patients who underwent CTPA, PESI clinical score was calculated and correlation was in between these two. of 50 patients, 38 are in high-risk group and 12 are in low-risk group. Main pulmonary artery, right/left pulmonary artery involved in 70% of high-risk group patients, which shows a statistically significant association between risk group (class) involvement of level of arteries by CT pulmonary angiography (p value 0.001).  By simply using this, 11 variable PESI score, one can predict the patients who are at high risk in the emergency department .  We can decide, which patient should undergo thrombolization according to the risk score.  Patients with high-risk score with immediate thrombolysis will have better results.
