No results posted yet for this study

Summary

Identify risk factors for developing chronic thromboembolic pulmonary hypertension after acute pulmonary embolism.

Determine echocardiographic predictors of chronic thromboembolic pulmonary hypertension.

Determine the radiological predictors of chronic thromboembolic pulmonary hypertension in CT pulmonary angiography.

Conditions

  • CTEPH Predictors

Interventions

DIAGNOSTIC_TEST

v/Q scanning & CT pulmonary angiography & Echocardiography

Echocardiography ( comparative follow up of the RVSF PASP TAPSE IVC). CT pulmonary angiography with assessment of the following parameters : Intravascular web. dilated bronchail arteries. Arterial retraction. dilated pulmonary arteries. RV/LV diameter more than 1. Flattening of interventricular septum. V/Q scanning Following ESC/ERS Guideline recommendations, V/Q is the preferred and recommended test for CTEPH. It has a sensitivity of \>96% and normal V/Q scan can rule out CTEPH . V/Q lung scintigraphy was interpreted as positive for CTEPH if there was at least one segmental or two sub-segmental mismatched perfusion defects, as proposed by the European Association of Nuclear Medicine (EANM) guidelines for the diagnosis of acute PE.
