Anesthetic Management of a PVC Ablation Complicated by Pericardial Tamponade and Subsequent Embolic Stroke (ASA 2025) - "Coagulopathy was treated with Kcentra, FFP, TXA, NovoSeven, and platelets to reverse anticoagulant effects and restore hemostasis. Given persistent neurological decline, extubation was delayed, prompting neuroimaging that revealed multiple acute strokes. Multimodal resuscitation and coagulation management were critical in stabilizing this patient for postoperative neurological assessment."

Management for Urgent Femur Fixation in a Post-Lung Transplant Patient on Apixaban with CKD and Distorted Neuraxial Anatomy (ASA 2025) - "As surgical timing approached the 72-hour threshold for increased hip fracture mortality, four-factor PCC (Kcentra) was administered. General anesthesia was administered, and the procedure continued uneventfully. The patient was discharged without complications."

Biochemical analysis of anticoagulant compounds in four-factor prothrombin complex concentrates (ISTH 2025) - "Aims To characterize pro- and anticoagulant content of three 4F-PCCs, Prothromplex (PKT; Takeda), Kcentra (KCT; CSL Behring), and Octaplex (OTX; Octapharma), and explore the effect of 4F-PCC heparin content on thrombin generation in vitro. Following heparin removal, PKT resulted in the highest increase in peak thrombin in normal plasma; in anticoagulated plasma, similar thrombin levels were observed for all 4F-PCCs.

Temporal Effects of 4F-PCC and ATIII in Mitigating TBI Induced BBB Permeability and Hemorrhage (ISTH 2025) - "Methods In Vitro: The trans-endothelial electrical resistance of thrombin challenged brain microvascular endothelial cell (BEC) monolayers was measured after treatment with 4F-PCC (Kcentra, CSL Behring) or Antithrombin-III (ATIII; Kybernin, CSL Behring)...One way ANOVA, Holm-Sidak’s post-hoc multiple comparison test, comparisons as indicated on the graph, ***p<0.001 n=5-10 per group.

Use of Andexanet Alpha Versus Standard of Care Among Patients Hospitalized With Upper and Lower Gastrointestinal Bleeding: A Retrospective, Multicenter, Comparative Effectiveness Study (ATS 2025) - "Patients who present with a gastrointestinal bleed (GIB) while on rivaroxaban or apixaban may receive reversal agents such as protein complex concentrate (PCC; KCentra) or Andexanet alfa (AA). In this retrospective, multicenter comparative effectiveness study, there were no differences in time to mortality in patients who received AA compared to those who received PCC. However, effect estimates for mortality, thromboembolic events, and need for transfusion all favored PCC over AA. Figure 1."

Successful Urgent Liver Transplantation in a High-Risk Patient on Therapeutic Apixaban: A Complex Case of End-Stage Liver Disease and Hepatocellular Carcinoma with Portal Vein Thrombosis (IARS-SOCCA 2025) - "Their suggestion was low molecular weight heparin as first line and vitamin K antagonists (Warfarin) be used as second line...Given apixaban use and the patient's ESLD and CKD3b, a multidisciplinary team discussed apixaban reversal with anti-inhibitor coagulant complex (FEIBA) vs prothrombin complex concentrate [human] (Kcentra); our institution has removed the FDA approved reversal agent for Xa inhibitors (recombinant Factor Xa) from formulary...Once the portal clamp was removed, one gram of tranexamic acid was administered...This case highlights the complexities of managing therapeutic anticoagulation with apixaban in urgent LT. Patients with ESLD are at high risk for any major surgery due to significant coagulopathy; however, in the setting of liver transplantation, a fine balance exists. In the prehepatic and anhepatic phases, it is important to minimize blood loss from the surgical perspective as well as adequately resuscitate without exacerbating venous..."

EFFICACY AND SAFETY OF HIGH-DOSE FOUR-FACTOR PROTHROMBIN COMPLEX CONCENTRATE: LEX-209 SUBANALYSIS (SCCM 2025) - P3 | "Introduction: The LEX-209 Phase 3 randomized controlled trial of investigational four-factor prothrombin complex concentrate (4F-PCC; Octaplex®/Balfaxar®, Octapharma) demonstrated hemostatic non-inferiority to the FDA-approved control 4F-PCC (Beriplex®/Kcentra®, CSL Behring) in rapid vitamin K antagonist (VKA) reversal before urgent surgery (p< 0.001). Investigational 4F-PCC, administered at the maximum permitted dose, appeared to be safe and effective for rapid VKA reversal in urgent surgery patients with significant bleeding risk. These findings further support the use of high-dose 4F-PCC for surgical patients needing rapid VKA reversal."

RARE CASE OF ACQUIRED CLOTTING FACTOR INHIBITOR FROM BLADDER CANCER (SCCM 2025) - "He received 7units of FFP, 2PRBC, Vitamin-K and KCENTRA over the first few days but hematuria and coagulopathy did not improve...He was started on steroids and Factor eight inhibitor bypass activity (FEIBA) treatment for ACFI...Treatment is 3 prong; 1) correct coagulopathy 2) replenish blood loss 3) stabilize/treat immune dyscrasia. Factor V inhibitors are rare but may arise from exposure to topical fibrin glues or bovine thrombin preparations that contain bovine factor V. Early recognition, confirmation and therapy initiation of ACFI is key to ensuring positive outcome and to avoid complications from life threatening bleed"

COMPARISON OF TWO DIFFERENT FIXED-DOSE FACTOR EIGHT INHIBITOR BYPASSING ACTIVITY (FEIBA) REGIMENS IN THE MANAGEMENT OF WARFARIN-ASSOCIATED COAGULOPATHIES. (WRMC 2025) - "Kcentra is the only FDA approved PCC for managing warfarin associated coagulopathies, but Factor VIII Inhibitor Bypass Activity (FEIBA) is commonly used in its place. Conclusions Our new FEIBA dosing recommendations resulted in more individuals achieving the post-FEIBA administration INR goal. Authors plan to finalize data collection and analysis in the coming months."

Rapido: Results from a UK-Wide Audit of 2477 Patients Who Received a Reversal Agent for a Direct Oral Anticoagulant (ASH 2024) - "Although a specific reversal agent for dabigatran, idarucizumab, was approved for use in the UK in 2016, the predominant option for patients taking apixaban, edoxaban, and rivaroxaban has until recently been off-licence prothrombin complex concentrate (PCC). Importantly, the data highlight delays in identification and treatment of bleeds. Further, detailed analysis of this rich dataset is on-going, and a propensity score-matched analysis of patients with GI hemorrhage will be performed to compare outcomes in patients treated with andexanet alfa, Beriplex and Octaplex."

Addition of PCC Does Not Improve the Performance of rTEG or ACT in the Measurement of Dabigatran Concentration. (ASA 2024) - "This was repeated with the addition of 1 unit/mL of PCC (KCentra, CSL Behring, Kong of Prussia, PA) to each sample. The addition of prothrombotic precursors did not improve the accuracy of either test in the determination of concentration of dabigatran. ACT or rTEG may be useful POCTs for use with dabigatran anticoagulation for CPB"

SPONTANEOUS RETROPHARYNGEAL HEMATOMA WITH THE USE OF APIXABAN (CHEST 2024) - "Given his positive history of Apixaban use, IV Decadron and Kcentra were administered...While most cases of RPHs have been associated with traumatic injuries, spontaneous cases have also been reported especially in patients on warfarin and rarely on rivaroxaban... Patients developing spontaneous RPH on warfarin are often switched to direct oral anticoagulants (DOAC). However, reinitiation of anticoagulation in patients with spontaneous RPH due to DOACs remains a challenge due to rare occurrence and hence limited literature."

Critical Hemodynamic Considerations for Adult Patients With Tetralogy of Fallot and Prior Blalock-Thomas-Taussig Shunt Surgery (ATS 2024) - "Case report: A 60-year-old male with a past medical history of TOF requiring multiple prior cardiac surgeries (Left-BT shunt; TOF repair; mechanical aortic and pulmonic valve replacement on chronic anticoagulation with warfarin) presented to the emergency department due to a several day history of black tarry stools...Given these findings, he received 5 units of packed red blood cells, a unit of fresh frozen plasma, 5 mg of vitamin K and Kcentra... This case highlights the importance of understanding the unique anatomical considerations in patients with TOF after BT shunt surgery. As a result of this procedure, a branch of the subclavian artery is connected to the pulmonary artery. Involvement of the subclavian artery for the shunt can have profound implications for hemodynamic monitoring."
