Fig 1 This figure demonstrates the relative change in maximal descending thoracic aortic diameter after thoracic endovascular aortic aneurysm repair (TEVAR) for chronic type B aortic dissection (cTBAD) with aneurysm. The differential impact of partial vs complete thrombosis of the false lumen (FL) led to significant differences (P = .02) in average diameter reduction after endograft repair.

Fig 2 This demonstrates a comparison of the average maximal thoracic aortic diameter change after thoracic endovascular aortic aneurysm repair (TEVAR) for chronic type B aortic dissection (cTBAD) with aneurysm formation as a function of residual false lumen (FL) patency. Patients with isolated infrarenal FL patency vs visceral aortic segmental patency vs distal descending thoracic aortic FL patency are compared. A significant difference (P < .0005) in diameter outcome is noted and primarily impacted by persistent perfusion of the FL in the distal descending thoracic aorta resulting in progression of aneurysm size.

Fig 3 Kaplan-Meier curve with 95% confidence intervals (CIs) of secondary intervention after thoracic endovascular aortic aneurysm repair (TEVAR) for chronic type B aortic dissection (cTBAD) with aneurysm. All displayed intervals have ≤10% standard error of the mean.

Fig 4 Life table estimate of long-term survival with 95% confidence intervals (CIs) after thoracic endovascular aortic aneurysm repair (TEVAR) for chronic type B aortic dissection (cTBAD) for aneurysm. All displayed intervals have ≤10% standard error of the mean.

Fig 5 This figure compares the proportion of patients surviving between cohorts requiring reintervention and those who did not. No statistically significant difference was noted between the two subgroups (log-rank, P = .48). All displayed intervals have ≤10% standard error of the mean.

Fig 6 Kaplan-Meier estimates of survival dichotomized by presence or absence of favorable aortic remodeling. Favorable aortic remodeling was defined as a ≥5 mm decrease in maximal descending thoracic aortic diameter and no need for aortic reintervention either at the intended treatment zone or remote aortic sites. No difference in estimated long-term survival is present between the two groups (log-rank, P = .18). All displayed intervals have ≤10% standard error of the mean.
