Fig 2 A, Color Doppler transesophageal echocardiogram (TEE) obtained after stent-graft implantation shows peri-stent leak with flow from true lumen (TL) to false lumen (FL) of aortic dissection (arrow). A1, Pulsed Doppler TEE confirms leak (high-velocity flow, 120 cm/s, with high-intensity signal). B, TEE-guided balloon inflation (arrows) seals stent graft to aortic wall. FL, False lumen. C, Color Doppler TEE shows leak resolution with initial false lumen (FL) thrombosis (marker of false lumen exclusion and successful procedure) 10 minutes after balloon inflation. TL, True lumen. C1, Pulse-Doppler TEE shows only Dacron porosity (slow-velocity flow, <50 cm/s, with poor signal intensity).
