A 56-year-old woman with right hemiplegia for recent cerebral bleeding suddenly complained of dyspnea and chest pain with hypoxia during rehabilitation. Eight days after this first attack, she suffered prolonged right heart failure and hypoxia due to recurrent pulmonary embolism. Arterial blood gas analysis of room air showed 34.5 mmHg of PaO2 and 29.2 mmHg of PaCO2. Echocardiography showed enlargement of the right atrium and ventricle with pulmonary hypertension. Enhanced chest computed tomography revealed pulmonary emboli from the main pulmonary artery to the periphery. Despite intensive treatment, heart failure and hypoxia did not improve. We conducted pulmonary embolectomy under cardiopulmonary bypass requiring percutaneous cardiopulmonary bypass support for 2 days due to right heart failure. She is currently doing well in the 9 months following surgery.

Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by chronic thrombi in the pulmonary arteries, causing pulmonary hypertension and right heart failure. Early and accurate diagnosis are essential for successful treatment but are often difficult because clinical signs and symptoms can be nonspecific and risk factors, such as history of venous thromboembolism, may not always be present. Here, we report a case involving a 76-year-old woman who demonstrated paradoxical cerebral embolism as the initial manifestation of CTEPH. She developed right hemiplegia without dyspnea or edema. Brain magnetic resonance imaging revealed multiple fresh infarctions, while transesophageal echocardiography revealed a patent foramen ovale. Based on these findings, she was diagnosed as having paradoxical cerebral embolism. During the search for the embolic source, right heart catheterization showed significant pulmonary hypertension and pulmonary angiography revealed chronic thrombi in the peripheral pulmonary arteries, consistent with a diagnosis of CTEPH. To our knowledge, this is the first case of CTEPH to be diagnosed with the onset of paradoxical cerebral embolism. Because CTEPH is the only potentially curable form of pulmonary hypertension, clinicians should consider paradoxical cerebral embolism as a possible initial manifestation of CTEPH.
