What is Unique characteristics of the type B aortic dissection patients with malperfusion in the Vascular Quality Initiative about?

## Objective: Type b aortic dissection (tbad) complicated by malperfusion carries high morbidity and mortality. the present study was undertaken to compare the characteristics of malperfusion and uncomplicated cohorts and to evaluate the long-term differences in survival using a granular, national registry. ## Methods: Patients with tbad entered into the thoracic endovascular aortic repair/complex endovascular aortic repair module of the vascular quality initiative from 2010 to 2019 were included. the demographic, radiographic, operative, postoperative, in-hospital, and long-term reintervention data were compared between the malperfusion and uncomplicated tbad groups using t tests and χ analysis, as appropriate. overall survival was compared using cox regression to generate survival curves. ## Results: Of the 2820 included patients, 2267 had uncomplicated tbad and 553 had malperfusion. the patients with malperfusion were younger (age, 55.8 vs 61.2 years; p < .001), were more often male (79.7% vs 68.1%; p < .001), had a higher preoperative creatinine (1.8 vs 1.1 mg/dl; p < .001), had more often presented with an american society of anesthesiologists class of 4 or 5 (81.9% vs 58.4%;
