Safety and efficacy of prothrombin complex concentrate (PCC) for anticoagulation reversal in patients undergoing urgent neurosurgical procedures: a systematic review and metaanalysis. Neurosurg Rev 2020; 44:1921-1931. [PMID: 33009989 DOI: 10.1007/s10143-020-01406-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 08/28/2020] [Accepted: 09/28/2020] [Indexed: 12/31/2022]
Abstract
Anticoagulant therapy poses a significant risk for patients undergoing emergency neurosurgery procedures, necessitating reversal with prothrombin complex concentrate (PCC) or fresh frozen plasma (FFP). Data on PCC efficacy lack consistency in this setting. This systematic review and metaanalysis aimed to evaluate efficacy and safety of PCC for anticoagulation reversal in the context of urgent neurosurgery. Articles from PubMed, Embase, and Cochrane databases were screened according to the PRISMA checklist. Adult patients receiving anticoagulation reversal with PCC for emergency neurosurgical procedures were included. When available, patients who received FFP were included as a comparison group. Pooled estimates of observational studies were calculated for efficacy and safety outcomes via random-effects modeling. Initial search returned 4505 articles, of which 15 studies met the inclusion criteria. Anticoagulants used included warfarin (83%), rivaroxaban (6.8%), phenprocoumon (6.1%), apixaban (2.2%), and dabigatran (1.5%). The mean International Normalized Ratio (INR) prePCC administration ranged from 2.3 to 11.7, while postPCC administration from 1.1 to 1.4. All-cause mortality at 30 days was 27% (95%CI 21, 34%; I2 = 44.6%; p-heterogeneity = 0.03) and incidence of thromboembolic events was 6.00% among patients treated with PCC (95%CI 4.00, 10.0%; I2 = 0%; p-heterogeneity = 0.83). Results comparing PCC and FFP demonstrated no statistically significant differences in INR reversal, mortality, or incidence of thromboembolic events. This metaanalysis demonstrated adequate safety and efficacy for PCC in the reversal of anticoagulation for urgent neurosurgical procedures. There was no significant difference between PCC and FFP, though further trials would be useful in demonstrating the safety and efficacy of PCC in this setting.

Abstract
Vitamin K antagonist therapy is associated with an increased bleeding risk, and clinicians often reverse anticoagulation in patients who require emergency surgical procedures. Current guidelines for rapid anticoagulation reversal for emergency surgery recommend four-factor prothrombin complex concentrate and vitamin K coadministration. The authors reviewed the current evidence on prothrombin complex concentrate treatment for vitamin K antagonist reversal in the perioperative setting, focusing on comparative studies and in the context of intracranial hemorrhage and cardiac surgery. The authors searched Cochrane Library and PubMed between January 2008 and December 2017 and retrieved 423 English-language papers, which they then screened for relevance to the perioperative setting; they identified 36 papers to include in this review. Prothrombin complex concentrate therapy was consistently shown to reduce international normalized ratio rapidly and control bleeding effectively. In comparative studies with plasma, prothrombin complex concentrate use was associated with a greater proportion of patients achieving target international normalized ratios rapidly, with improved hemostasis. No differences in thromboembolic event rates were seen between prothrombin complex concentrate and plasma, with prothrombin complex concentrate also demonstrating a lower risk of fluid overload events. Overall, the studies the authors reviewed support current recommendations favoring prothrombin complex concentrate therapy in patients requiring vitamin K antagonist reversal before emergency surgery.

Abstract
Objective: The number of patients presenting with warfarin-associated intracranial bleeding and needing neurosurgical intervention is growing. Prothrombin complex concentrate (PCC) is commonly used for anti-coagulation reversal before emergent surgery. We present our experience with PCC use in patients presenting with coagulopathy and needing urgent craniotomy. Methods: We retrospectively identified all patients presenting with intracranial bleeding and coagulopathy due to warfarin use, requiring urgent neurosurgical procedures, from January, 2014 (implementation of 4-PCC therapy) until December, 2016. For coagulation reversal, all patients received 4-PCC (Octaplex) and vitamin K. Results: Thirty-five consecutive patients (17 men; median age 72 years) were administered 4-PCC before emergent neurosurgical procedures. The majority of patients presented with traumatic subdural hematoma (62%) and spontaneous intracerebral hemorrhage (32%). All patients were taking warfarin. Median international normalized ratio (INR) on admission was 2.94 (range: 1.20 to 8.60). Median 4-PCC dose was 2000 I.U. (range: 500 I.U. to 3000 I.U.). There was a statically significant decrease in INR (p < 0.01), PT (p < 0.01), and PTT (p = 0.02) after 4-PCC administration. Postoperative INR values were ≤3.00 in all patients, and seven (20%) patients had normal INR values. There were no 4-PCC related complications. Four (11%) patients developed subdural/epidural hematoma and 20 (57%) patients died. Mortality was associated with lower Glasgow coma scale (GCS) score. Conclusions: The 4-PCC facilitates INR reversal and surgery in patients presenting with warfarin-associated coagulopathy and intracranial bleeding requiring urgent neurosurgical intervention.

Abstract
Although the use of dabigatran and rivaroxaban are increasing, data on the reversal of their effects are limited. The lack of reliable monitoring methods and specific reversal agents renders treatment strategies empirical, and as a result, treatment consists mainly of supportive measures. Therefore, we performed a systematic search of the PubMed database to find studies and reviews pertaining to oral anticoagulation reversal strategies. This review discusses current anticoagulation reversal recommendations for the oral anticoagulants warfarin, dabigatran, and rivaroxaban for patients at a heightened risk of bleeding, actively bleeding, or those in need of preprocedural anticoagulation reversal. We highlight the literature that shaped these recommendations and provide directions for future research to address knowledge gaps. Although reliable recommendations are available for anticoagulation reversal in patients treated with warfarin, guidance on the reversal of dabigatran and rivaroxaban is varied and equivocal. Given the increasing use of the newer agents, focused research is needed to identify effective reversal strategies and develop and implement an accurate method (assay) to guide reversal of the newer agents. Determining patient-specific factors that influence the effectiveness of reversal treatments and comparing the effectiveness of various treatment strategies are pertinent areas for future anticoagulation reversal research.

Abstract
Atrial fibrillation (AF) is a common arrhythmia that is associated with an increased risk of stroke, particularly in the elderly. Traditionally, a vitamin K antagonist such as warfarin is prescribed for stroke prevention. Warfarin is effective at lowering stroke risk but has several limitations due to food restrictions, drug interactions, and a narrow therapeutic window. Various novel oral anticoagulants (NOACs) are available or under development to provide alternative treatment options. This article reviews the efficacy and safety of three NOACs (dabigatran etexilate, rivaroxaban, and apixaban) in addition to warfarin and aspirin, for prevention of stroke in patients with AF, focusing on the elderly population. Results of clinical trials demonstrate that the efficacy of NOACs for stroke prevention in patients with AF is as good as or better than that of warfarin. The NOACs are also associated with an equivalent or lower risk of bleeding. Regardless of the medication chosen, older patients with AF must be treated cautiously due to an increased risk of stroke and bleeding, as well as potential challenges related to drug interactions and monitoring requirements. NOACs may be suitable alternatives to warfarin for stroke prevention in older patients due to several advantages, including a faster onset of action, few drug or food interactions, and no requirement for regular monitoring. However, dose adjustments may be required for certain patients, such as those with severe renal impairment or in the setting of drug interactions.

Real world usage of PCC to "rapidly" correct warfarin induced coagulopathy. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2012; 11:500-5. [PMID: 23114527 DOI: 10.2450/2012.0113-12] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 06/05/2012] [Accepted: 08/09/2012] [Indexed: 11/21/2022]
Abstract
BACKGROUND Life threatening bleeding and emergency procedures in patients on vitamin K antagonists are indications for urgent reversal with prothrombin complex concentrate and vitamin K. Rapid reversal in these situations is emphasized in the literature and guidelines, but only very limited information is available on its real life use, especially on the timing of treatment in relation to presentation. MATERIALS AND METHODS We retrospectively audited emergency warfarin reversal in 131 consecutive patients. We studied the indication, use of vitamin K, time between presentation and administration of vitamin K and PCC, effectiveness in INR reduction and clinical outcome. RESULTS The median PCC dose was 26.8 IU/kg. The median INR was reduced from 3.1 to 1.2. Vitamin K (5 mg) was given in 91.6% of evaluable patients. We found significant delays in administration of PCC and vitamin K. The median time between presentation and administration of vitamin K/PCC was 3.6 and 5.2 hours respectively. The times in intracranial haemorrhage were 2.7 and 3.0 hours and in emergency procedures 17.4 and 15.9 hours respectively. Mortality related to bleeding was 7.6% overall but in patients with intracranial haemorrhage 22.8%. The thrombotic rate within 7 days of reversal was 1.5%. DISCUSSION The local protocol for reversal with PCC and vitamin K was adhered to well but the delay in pre-procedural patients, suggests that intravenous vitamin K alone may be sufficient in many cases and PCC administration can be avoided by better planning. Intracranial haemorrhage in warfarinised patients carries a high mortality. Treatment delays should be avoided by making PCC stocks available within emergency departments, simple dosing structures independent of INR and administering PCC without waiting for INR and CT scan results in those with strong suspicion of intracranial haemorrhage and clear trauma. Future reports and studies should always include the time from presentation to PCC treatment.
