Abstract
|
|
|
Chronic thromboembolic pulmonary hypertension is the result of single or recurrent pulmonary emboliarising from sites of venous thrombosis. For reasons still unknown, the emboli in chronic thromboembolic pulmonary hypertension patients do not
resolve
completely. The vessels involved are the central elastic vessels such as main, lobar and/or segmental arteries. Such patients should be considered separately from acute pulmonary embolism because their thrombi are potentially removable by
surgical
thromboendarterectomy.
The prevalence of deep vein thrombosis and pulmonory embolism seems to be low in Korea.
But, we experienced 3 cases of chronic thromboembolic pulmonary hypertension in a year recently. They complained of progressive exertional dyspnea for a few months to years. Lung perfusion scan revealed multiple segmental perfusion defects and
pulmonary
angiography, spiral CT reveal multiple defects in main and lobar pulmonary arteries.
One patient(case 1) died of low output cardiac failure while waiting for operation, and another patient(case 2) has been treated medically at OPD, one(case 3) was treated by right main pulmonary artery thromboendarterectomy and his pulmonary
arterial
pressure was sucessfully dropped from 60/39 mmHg to 26/18 mmHg.
We reported 3 cases of chronic thromboembolic pulmonary hypertension with review of literatures.
