A case of TEVAR for acute aortic dissection after MICS AVR and retroperitoneal tumor resection.

If multiple treatments are performed within a short time, when something occurs, it is difficult to identify its cause. Here, we present a case of thoracic endovascular aortic repair (TEVAR) for acute aortic dissection (AAD) after multiple treatments. A 76-year-old woman underwent minimally invasive aortic valve replacement, transcatheter lumbar artery embolism and retroperitoneal tumor resection within a short period of time. After a series of procedures, the patient experienced sudden back pain, and computed tomography revealed an AAD Type B. Her back pain persisted; therefore, we performed TEVAR, and the post-operative course was uneventful. In this case, the relationship between AAD and treatment before AAD was unclear, but AAD should considered when performing treatments that may cause AAD.
