RESUMO
Frozen elephant trunk( FET) technique is an effective procedure used to repair aortic arch aneurysm and aortic dissection. We modified FET technique in order to reduce bleeding, which we named "delayed deployment technique." This procedure is performed in the following manner: 1. A tube graft is anastomosed to the proximal descending aorta using open distal method. 2. A FET is deployed within the tube graft and the descending aorta. 3. Proximal end of the inner FET and the outer tube graft is trimmed at the same position. 4. A four-branched graft is anastomosed to doubly layered distal grafts. Since the FET is directly connected to the arch graft, anastomotic site in the proximal descending aorta can be free from direct blood flow. In addition, stent portion of the FET supports the aortic anastomosis from inside. We believe this method is useful for hemostasis.

Hybrid repair of a thoracoabdominal aortic aneurysm comprising thoracic endovascular aortic repair and total renovisceral debranching is a feasible alternative to open repair, especially for high-risk patients. However, transperitoneal debranching is a relatively complicated procedure that requires deep dissection around vital abdominal organs. Therefore, we developed a new debranching technique called Chunnel debranching, which was characterized by transaortic tunneling using a covered stent between the target artery and the prosthetic graft anastomosed on the aneurysmal wall using an inclusion technique. This procedure increases the feasibility of renovisceral debranching with fewer dissections than conventional transperitoneal debranching.

CASE PRESENTATION: A 57-year-old woman was admitted to our hospital for an abnormal chest shadow found during routine chest radiography. She had no respiratory symptoms. Her medical history included dyslipidemia, and her surgical history included conization for cervical cancer at age 38 years. She was a social drinker and ex-smoker of approximately 10 cigarettes per day (from ages 20 to 30 years); she denied recreational drug use.
