Safety of Prothombin Complex Concentrate to Control Excess Bleeding During Continuous Flow LVAD Insertion.

In cardiovascular surgery, hemostatic complexities require the provision of blood products to control bleeding as well as the use of a number of hemostatic agents, some of which cause significant morbidity. Among these agents is prothrombin complex concentrates (PCC), however there is no clear consensus on PCC use in cardiovascular surgery. To investigate the safety of PCC in patients undergoing left ventricular assist device (LVAD) placement, we reviewed our single institution experience to examine the incidence of thromboembolic events and a variety of hospital markers including morbidity and mortality. A retrospective review was conducted of patients who underwent LVAD placement between January 2010 and October 2012. Patients who received intraoperative PCC constituted the PCC group (n = 41) and those who did not constituted the non-PCC group (n = 27). The overall incidence of thromboembolic events at 3 months postoperative was 12 (29.3%) in the PCC group compared with six (22.2%) in the non-PCC group, respectively (p > 0.05). Morbidity did not differ between groups and one patient in the PCC group died. The intraoperative use of PCC in LVAD insertion does not appear to be associated with a significant increase in thromboembolic events; however, larger randomized trials are needed to confirm these findings.
