Prognostic dynamic nomogram integrated with metabolic acidosis for in-hospital mortality and organ malperfusion in acute type B aortic dissection patients undergoing thoracic endovascular aortic repair

Table 3 Multivariable predictors of in-hospital mortality and organ malperfusion (derivation cohort)

Variables	Multivariate
Variables	OR	95% CI	P value
Base excess*			< 0.001
Moderate risk versus low risk	4.98	2.01–12.32	0.001
High risk versus low risk	8.40	2.09–33.84	0.003
Renal dysfunction	3.99	1.62–9.81	0.003
D-dimer ≥ 5.44 μg/mL	3.82	1.55–9.46	0.004
Albumin ≤ 30 g/L	4.51	1.88–10.80	0.001
Diameter ≥ 55 mm	6.51	1.89–22.45	0.003

The predictive model was adjusted by pH, lactate, bicarbonate, decreased peripheral arterial pulse, hypertension, coronary artery disease, stroke, anemia, estimated glomerular filtration rate < 60 mL/min/1.73 m², extent of the dissection, blood supply of visceral arteries (coeliac artery, superior mesenteric artery, left renal artery and right renal artery)
OR, odds ratio; CI, confidence interval
*Base excess was divided into low risk group (> − 5), moderate risk group (− 10 to − 5) and high risk group (≤ − 10)
