We report two cases of graft migration during open stent grafting, detected by transesophageal echocardiography (TEE). The incidence was 3.7% in our series. The length of landing zone was reduced from 45 mm to 25 mm in case 1 and from 50 mm to 22 mm in case 2 before chest closure. Aneurysmal protrusion on the greater curvature with thin mural thrombus were findings common in both cases. Although additional intervention was not done based on the TEE findings of no endoleak and thrombus formation in the aneurysm, and postoperative course was uneventful, meticulous imaging check-up was needed.
