[Pulmonary thromboendarterectomy for an elderly patient].
We describe a case of successful pulmonary thromboendarterectomy for an elderly patient. A 75-year-old female suffered from severe dyspnea in spite of administration of pulmonary vascular dilators and anticoagulants. Her pulmonary vascular resistance was 545 dyn x sec x cm(-5) and, her pulmonary angiogram and perfusion scan revealed that almost all branches of her right pulmonary artery were occluded. Pulmonary thromboendarterectomy was performed under cardiopulmonary bypass. A videoscope was employed to see inside of the pulmonary artery. Flexible aspirator chip was used to peed abnormal intima easily. A non-invasive intracranial oxygen saturation monitor was used for secure circulatory arrest. The duration of cardiopulmonary bypass was 101 minutes and minimum body temperature was 24.5 degrees C. Her symptoms improved markedly after operation, and she went back to the ordinary life. Pulmonary thromboendarterectomy was useful even for elderly patients under some modifications of the operative procedures.
