Condition: Pulmonary Thromboendarterectomy · Pulmonary Embolism and Thrombosis · Sponsor: University of Sao Paulo General Hospital
Chronic thromboembolic pulmonary hypertension (CTEPH) is a condition in which old blood clots block the blood vessels in the lungs, making it harder for the heart to pump blood through the lungs. Surgery called pulmonary thromboendarterectomy can remove these clots and improve blood flow, but doctors need reliable ways to evaluate lung blood flow before and after surgery. This study will evaluate a bedside imaging method called electrical impedance tomography (EIT), which can measure how blood flows through different regions of the lungs without radiation or invasive procedures. Patients undergoing surgery for CTEPH will be monitored with EIT before and after surgery, and the results will be compared with standard lung perfusion imaging. The goal of this study is to determine whether EIT can provide useful information about lung blood flow and changes after surgery, and whether it could serve as a complementary bedside tool to help monitor patients with CTEPH.
