Endovascular Treatment with Sandwich Technique for Thoracoabdominal Aortic Aneurysm Treatment

Abstract

Crawford type V thoracoabdominal aortic aneurysm (TAAA) was detected in a 76-year-old male. His metastatic liver tumor had been treated by chemotherapy. The maximum dimension of the aneurysm was 67 mm. The distance from the distal end of the TAAA to celiac axis (CA) was only 5 mm. Preserving blood flow of the CA, TEVAR was performed with the sandwich technique. The postoperative course was uneventful. No symptoms of splanchnic ischemia were observed. Postoperative CT showed no endoleak. The blood flow of CA was maintained. Although the long-term prognosis has not been well documented, this could be a minimally invasive and feasible treatment for TAAA.
