Abstract
A 77-year-old man presented with a 55-mm infrarenal aortic aneurysm associated with old myocardial infarction, severe diabetes mellitus, and an undiagnosed pleural tumor. Endovascular aortic repair (EVAR) via the femoral artery and thoracoscopic pleural biopsy was performed under general anesthesia. On EVAR, there were neither technical difficulties nor unstable circulatory dynamics such as hypotension during the procedure. After extubation in the intensive care unit, he developed paraplegia. Emergency cerebrospinal fluid drainage, steroid administration, and arterial pressure augmentation were ineffective. On postoperative computed tomography, aortic dissection and endoleak were not found but partial infarctions of the right kidney were revealed. Pathological diagnosis of pleural tumor was pleural dissemination of pulmonary large cell carcinoma.
