%X BACKGROUND: Use of recombinant activated factor VII (rFVIIa) to achieve hemostasis during cardiac surgery continues to be debated, as support for its efficacy and safety has not been consistent. We examined our experience with rFVIIa for achieving hemostasis in high-risk patients undergoing complex ascending aortic surgery.
METHODS: We reviewed patients who underwent complex ascending aortic surgery performed by a single surgeon (C. K. R.) from August 2014 to February 2019. Outcomes of patients who received rFVIIa were compared with those who did not.
RESULTS: Of 59 consecutive patients, 20 patients (33.9%) received rFVIIa, whereas 39 (66.1%) did not. Median dose was 45.4 mcg/kg. rFVIIa was administered intraoperatively to 95% of patients who received it. Most patients underwent combined aortic valve, ascending aorta, and aortic arch surgery (80.0% vs. 64.1%, p = .52). Patients receiving rFVIIa had longer mean cross clamp times (212 vs. 173 min, p = .03) and received a greater median number of intraoperative blood products (18.5 vs. 12.0, p < .001). The number of patients who needed postoperative products (75.0% vs. 60.5%, p = .39), the median number of blood products transfused postoperatively (2 vs. 2, p = .40), and chest tube output (1138 vs. 805 ml, p = .17) were similar between groups. In-hospital mortality was similar between groups (10.0% vs. 10.3%, p = 1.00). Incidences of postoperative stroke (10.0% vs. 13.5%, p = 1.00) and thromboembolic events (10.0% vs. 13.5%, p = 1.00) were similar.
CONCLUSIONS: Administration of rFVIIa intraoperatively for refractory bleeding during complex ascending aortic surgery provided hemostasis without greater in-hospital mortality or a higher risk of stroke and thromboembolic events.
