Abstract

Background: Surgery for acute type A aortic dissection (ATAAD) is often complicated by excessive bleeding. Recombinant factor VIIa (rFVIIa) effectively treats refractory bleeding associated with ATAAD surgery; however, adverse effects of rFVIIa in these patients have not been fully assessed. Here we evaluated rFVIIa treatment in ATAAD surgery using the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) database. Methods: This was a multicenter, propensity score-matched, retrospective study. Information about rFVIIa use was available for 761 patients, of whom 171 were treated with rFVIIa. We successfully matched 120 patients treated with rFVIIa with 120 controls. Primary endpoints were in-hospital mortality, postoperative... (More)

Here we evaluated rFVIIa treatment in ATAAD surgery using the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) database. Methods: This was a multicenter, propensity score-matched, retrospective study. Information about rFVIIa use was available for 761 patients, of whom 171 were treated with rFVIIa. We successfully matched 120 patients treated with rFVIIa with 120 controls. Primary endpoints were in-hospital mortality, postoperative stroke, and renal replacement therapy (RRT). Survival data were presented using Kaplan-Meier estimates. Results: Compared with controls, patients treated with rFVIIa received more transfusions of packed red blood cells (median, 9.0 U [4.0-17.0 U] vs 5.0 U [2.0-11.0 U]; P = .008), platelets (4.0 U [2.0-8.0 U] vs 2.0 U [1.0-4.4 U]; P <.001), and fresh frozen plasma (8.0 U [4.0-18.0 U] vs 5.5 U [2.0-10.3 U]; P = .01) underwent reexploration for bleeding more often (31.0% vs 16.8%; P = .014); and had greater 24-hour chest tube output (1500 L [835-2500 mL] vs 990 mL [520-1720 mL]). Treatment with rFVIIa was not associated with significantly increased rates of in-hospital mortality (odds ratio [OR], 0.74; 95% confidence interval [CI], 0.34-1.55; P = .487), postoperative stroke (OR, 1.75; 95% CI, 0.82-3.91; P = .163), or RRT (OR, 1.18; 95% CI, 0.48-2.92; P = .839). Conclusions: In this propensity-matched cohort study of patients undergoing ATAAD surgery, treatment with rFVIIa for major bleeding was not associated with a significantly increased risk of stroke, RRT, or mortality.
