A pulmonary CT angiography was performed to evaluate recurrent pulmonary artery thrombosis on post-operative day 11.

A 43-year-old male patient, with a history of chronic thromboembolic pulmonary hypertension with progressive dyspnea and worsening functional status presented for definitive surgical treatment. He underwent thromboendarterectomy which was complicated by acute right ventricular dysfunction requiring venoarterial extracorporeal membrane oxygenation (VA ECMO). Post-operative attempts to wean the patient from VA ECMO were unsuccessful, and echocardiography revealed worsening right heart failure. A pulmonary CT angiography (CTA) was requested to assess for recurrent pulmonary artery thrombosis on post-operative day 11.

The outcomes by Siemens Healthineers customers described herein are based on results that were achieved in the customer’s unique setting. Since there is no “typical” hospital and many variables exist (e.g., hospital size, case mix, level of IT adoption) there can be no guarantee that other customers will achieve the same results.
