Thoracic Endovascular Aortic Repair for Perigraft Seroma After Ascending Aorta Replacement

We report on a successful thoracic endovascular aortic repair for perigraft seroma (PGS) after ascending aorta replacement (AAR). An 82-year-old man underwent AAR. Two years after the operation, computed tomography showed a 75-mm PGS around the ascending aorta. The Valiant Navion thoracic stent graft system was deployed along the ascending aorta because of a minimally invasive procedure. Computed tomography showed that the diameter of the PGS had decreased to 68 mm. Two years after discharge, the diameter of the PGS was unchanged. It may be prudent to consider thoracic endovascular aortic repair for PGS after AAR.
