Frozen elephant technique has been used to treat extensive aortic pathology (EAP) in either one or two stage procedures. Rapid expansion of the downstream aorta following frozen elephant technique was not reported. A 28-year-old man was referred to our clinic with a dilated abdominal aorta. He had a family history of Marfan syndrome. Contrast-enhanced computed tomography of the body revealed an EAP, including annuloaortic ectasia, an aortic aneurysm in the distal thoracic aorta, and a thoracoabdominal aortic aneurysm (Crawford type IV). Transthoracic echocardiography demonstrated mild aortic regurgitation. The patient underwent aortic root replacement (Bentall procedure) and total arch replacement (TAR) with the frozen elephant technique using a FROZENIX-open stent-graft. On postoperative day 8, the patient reported backache; computed tomography of the chest revealed the expansion of the descending aorta and pericardial effusion. We suspected an impending rupture of the thoracic aortic aneurysm and cardiac tamponade. He underwent an emergent reoperation, including a pericardial window for drainage and thoracic endovascular aortic repair (TEVAR) for the rapid expansion of the thoracic descending aorta. The postoperative course was uneventful. To the best of our knowledge, this is the first case of rapid expansion of the descending aortic aneurysm following TAR with the frozen elephant technique, which was successfully treated with an additional endovascular re-intervention. Endovascular re-intervention could be safely completed because of the stented graft used for the frozen elephant technique. Although frozen elephant technique (FET) is technically favorable for additional TEVAR, close follow-up of all patients undergoing
