BACKGROUND: Few studies have investigated the characteristics and long-term outcomes of type B aortic dissection (BAD) patients with simple renal cysts (SRC) after thoracic endovascular aortic repair (TEVAR).
METHODS: A multi-center retrospective cohort study was performed, including 718 BAD patients undergoing TEVAR from 2003 to 2016. The prevalence of SRC was 34.5% (n = 248). After propensity score matching, 214 matched pairs were selected for further analysis. Primary outcomes were long-term aortic-related adverse events (ARAEs). The effects of SRC in each subgroup of interest and their interactions were analyzed.
RESULTS: BAD patients with SRC were older and had a greater prevalence of comorbidities, including hypertension, coronary artery disease and chronic occlusive pulmonary disease. In addition, the SRC group presented a greater proportion of pleural effusion and aortic calcification. Compared with the non-SRC group, a significantly higher maximal diameter of ascending aorta was observed in the SRC group. Apart from the timing of the operation, no differences were found in the medication regime or intra-operative parameters. In the matched population, patients with SRC were at a higher risk of ARAEs in the long term. The multivariable Cox model indicated that SRC was an independent predictor of long-term ARAEs (hazard ratio: 1.84, 95% confidence interval: 1.13-3.00). The interaction between SRC and hypertension on rupture after TEVAR was statistically significant (p = 0.023).
CONCLUSIONS: Compared with the non-SRC group, BAD patients with SRC experienced a higher risk of long-term ARAEs after TEVAR. Among the SRC subgroup, hypertensive patients had the highest risk of rupture after TEVAR.
