Abstract
OBJECTIVE Antiplatelet medications are increasingly being used for primary and secondary prevention of ischemic attacks owing to the increasing prevalence of ischemic stroke occurrences. Currently, many patients receive antiplatelet therapy (APT) to prevent thromboembolic events. However, long-term use of APT might also lead to an increased occurrence of intracerebral hemorrhage (ICH) and affect the prognosis of patients with ICH. Furthermore, some research suggest that restarting APT for patients who have previously experienced ICH may result in rebleeding events. The precise relationship between APT and ICH remains unknown. METHODS We searched PubMed for the most recent related literature and summarized the findings from various studies. The search terms included "antiplatelet," "intracerebral hemorrhage," "cerebral microbleeds," "hematoma expansion," "recurrent," and "reinitiate." Clinical studies involving human subjects were ultimately included and interpreted in this review, and animal studies were not discussed. RESULTS When individuals are administered APT, the risk of thrombotic events should be weighted against the risk of bleeding. In general, for some patients' concomitant with risk factors of thrombotic events, the advantages of antiplatelet medication may outweigh the inherent risk of rebleeding. However, the use of antiplatelet medications for other patients with a higher risk of bleeding should be carefully evaluated and closely monitored. In the future, a quantifiable system for assessing thrombotic risk and bleeding risk will be necessary. After evaluation, the appropriate time to restart APT for ICH patients should be determined to prevent underlying ischemic stroke events. According to the present study results and expert experience, most patients now restart APT at around 1 week following the onset of ICH. Nevertheless, the precise time to restart APT should be chosen on a case-by-case basis as per the patient's risk of embolic events and recurrent bleeding. More compelling evidence-based medicine evidence is needed in the future. CONCLUSION This review thoroughly discusses the relationship between APT and the development of ICH, the impact of APT on the course and prognosis of ICH patients, and the factors influencing the decision to restart APT after ICH. However, different studies' conclusions are inconsistent due to the differences in quality control. To support future clinical decisions, more large-scale randomized controlled trials are required.

Abstract
Introduction and importance Subarachnoid hemorrhage (SAH) is mostly associated with head trauma. Non-traumatic subarachnoid hemorrhage is mostly due to vascular abnormalities: either hemorrhage from ruptured aneurysm or bleeding from arteriovenous malformation. Aneurysmal hemorrhage is the biggest cause in non-traumatic cases. Warfarin is associated with cerebral intraparenchymal hemorrhage, but it is rarely associated with SAH. Case presentation Here, we report the case of a 45-year-old male patient who was admitted to the neurology ward of our hospital due to acute ischemic stroke. The patient was treated with a vitamin K antagonist (warfarin). However, on the third day, his condition deteriorated (his GCS regressed from 11/15 to 5/15). His pupils were anisocoric. Brain CT showed extensive subarachnoid hemorrhage without intraparenchymal involvement. Cerebral magnetic resonance angiography ruled out aneurysmal rupture. The patient was intubated and transferred to the intensive care unit. Due to his poor condition, neurosurgical intervention could not be done. The patient was managed conservatively, but the patient passed away 4 days later in the intensive care unit. Clinical discussion Non-traumatic SAH is mostly caused by aneurysmal rupture. Warfarin increases the risk of intracranial hemorrhage and mostly causes intraparenchymal hemorrhage. Isolated warfarin-related SAH without parenchymal involvement is a rare event. Here we present a young male patient with an isolated warfarin-induced SAH. Conclusion Warfarin is rarely associated with isolated subarachnoid hemorrhage. This case highlights a young male patient with spontaneous SAH after warfarin therapy for acute ischemic stroke. Aneurysmal rupture and trauma should be excluded before a diagnosis of warfarin-induced SAH is made.

Abstract
Hematoma volume is the strongest predictor of morbidity and mortality after intracerebral hemorrhage. Protection against early hematoma growth is therefore the mainstay of therapeutic intervention for acute intracerebral hemorrhage, but the current armamentarium is restricted to early blood pressure lowering and emergent reversal for anticoagulant agents. Although intensive lowering of systolic blood pressure to <140 mmHg appears likely to prevent hematoma growth, two recent randomized trials, INTERACT-2 and ATACH-2, demonstrated non-significant trends of reduced hematoma enlargement by intensive blood pressure control, with only a small magnitude of benefit or no benefit for clinical outcomes. While oral anticoagulants can be immediately reversed by prothrombin complex concentrate, or the newly developed idarucizumab for direct thrombin inhibitor or andexanet for factor Xa inhibitors, the situation regarding reversal of antiplatelet agents is not yet quite as advanced. However, considering at most the approximately 10% rate of anticoagulant use among patients with intracerebral hemorrhage, what is most essential for patients with intracerebral hemorrhage in general is early hemostatic therapy. Tranexamic acid may safely reduce hematoma expansion, but its hemostatic effect was insufficient to be translated into improved functional outcomes in the TICH-2 randomized trial with 2,325 participants. In this context, recombinant activated factor VII (rFVIIa) is a candidate to be added to the armory against hematoma enlargement. The FAST, a phase 3 trial that compared doses of 80 and 20 μg/kg rFVIIa with placebo in 841 patients within 4 h after the stroke onset, showed a significant reduction in hematoma growth with rFVIIa treatment, but demonstrated no significant difference in the proportion of patients with severe disability or death. However, a post hoc analysis of the FAST trial suggested a benefit of rFVIIa in a target subgroup of younger patients without extensive bleeding at baseline when treated earlier after stroke onset. The FASTEST trial is now being prepared to determine this potential benefit of rFVIIa, reflecting the pressing need to develop therapeutic strategies against hematoma enlargement, a powerful but modifiable prognostic factor in patients with intracerebral hemorrhage.

Abstract
As intracerebral hemorrahge becomes more frequent as a result of an aging population with greater comorbidities, rapid identification and reversal of precipitators becomes increasingly paramount. The aformentioned population will ever more likely be on some form of anticoagulant therapy. Understanding the mechanisms of these agents and means by which to reverse them early on is critical in managing the acute intracerebral hemorrhage.

Abstract
SummaryAcute venous thromboembolism (VTE) is treated with parenteral administration of heparin or derivatives, in conjunction with oral vitamin K antagonists (VKAs) to reach and maintain INR values between 2.0 and 3.0 for at least 3 months; the duration of a further period of treatment for secondary prevention of recurrences is still matter of debate. If bleeding occurs during treatment the decision will be based on: a) type of bleeding (major or minor), and b) thrombotic risk if anticoagulation is withheld (characteristics of patients and time elapsed from the index VTE). In case of major bleeding anticoagulation should be stopped and reversed. A first but insufficient measure is i.v. vitamin K administration. Fresh frozen plasma is widely used; however, large volumes are needed (at least 15 mL/kg body weight) with risk for fluid overload. Prothrombin complex concentrate infusion, with 3 or (better) the 4 pro-coagulant factors, is a more efficient (fast and safe) measure. In patients at high thrombotic risk (first month or other conditions) and absolute contraindication for anticoagulation a caval filter is recommended, to avoid as much as possible lifethreatening pulmonary embolism.

Abstract
: When patients on anticoagulation present with intracranial bleeding, stopping the bleeding is paramount. Despite the availability of multiple options to reverse anticoagulation, no study has directly compared the effectiveness of the procoagulants recombinant activated factor VII (rFVIIa), the rFVIIa and 3-factor prothrombin complex concentrate (PCC) combination, and 4-factor PCC on improving patient outcomes compared with a control. This study examined the medical records of 197 warfarin patients with intracranial hemorrhage, an initial international normalized ratio (INR) greater than 1.5, and who received rFVIIa (26), the combination (84), 4-PCC (50), or no procoagulant, the control group (37). Mortality, length of stay, location discharged, change in INR prior to and postdrug administration, plasma use, and number of thromboembolic complications were used to assess effectiveness. Although INR decreased in all groups (1.31 rFVIIa vs. 2.04 combination vs. 1.41 4-PCC vs. 1.20 control, P = 0.07), the combination group had the greatest percentage to reach an INR of less than 1.3 (46.2 vs. 73.8 vs. 58.0 vs. 43.2%, P = 0.004). The combination and control groups experienced a high, though nonsignificant, number of thromboembolic complications (5.6 vs. 19.0 vs. 7.7 vs. 12.9%, P = 0.533). The rFVIIa group used the most plasma and had the longest length of stay. Mortality did not differ significantly among groups. Although the combination improved INR compared with control, this had a high number of complications. Judicious use of procoagulants is recommended due to their expense and lack of significant improvement in outcomes compared with control.

Abstract
Purpose—
Symptomatic intracranial hemorrhage (sICH) is the most feared complication of intravenous thrombolytic therapy in acute ischemic stroke. Treatment of sICH is based on expert opinion and small case series, with the efficacy of such treatments not well established. This document aims to provide an overview of sICH with a focus on pathophysiology and treatment.
Methods—
A literature review was performed for randomized trials, prospective and retrospective studies, opinion papers, case series, and case reports on the definitions, epidemiology, risk factors, pathophysiology, treatment, and outcome of sICH. The document sections were divided among writing group members who performed the literature review, summarized the literature, and provided suggestions on the diagnosis and treatment of patients with sICH caused by systemic thrombolysis with alteplase. Several drafts were circulated among writing group members until a consensus was achieved.
Results—
sICH is an uncommon but severe complication of systemic thrombolysis in acute ischemic stroke. Prompt diagnosis and early correction of the coagulopathy after alteplase have remained the mainstay of treatment. Further research is required to establish treatments aimed at maintaining integrity of the blood-brain barrier in acute ischemic stroke based on inhibition of the underlying biochemical processes.

Abstract
SummaryProthrombin complex concentrates (PCC) can rapidly normalise prolonged prothrombin time, induced by vitamin K antagonists (VKA). We conducted a multicentre retrospective study to investigate whether reversal of VKA coagulopathy with 4-factor PCC improves the survival of patients with VKA-related intracerebral haemorrhage as compared to plasma. We included 135 consecutive patients with VKA-related intracerebral haemorrhage treated either with plasma (mainly in Canada) or 4-factor PCC (The Netherlands and Sweden) for the reversal of VKA. Data on characteristics of the patients and the haemorrhage were collected. The volume of intracerebral haematoma was calculated from the first computed tomography (CT) scan. The unadjusted and adjusted odds ratio (OR) for 30-day all-cause mortality in both treatment groups was compared using logistic regression. Patients who received plasma (n=35, median 4 units) more often had diabetes, antiplatelet therapy, and intraventricular haemorrhage on the initial CT scans than patients who received PCC (n=100, median 22.5 IU/kg [interquartile range 20–26 IU], median of total dose 1,700 IU). The volume of intracerebral haematoma was larger in the plasma-treated group compared to the PCC-treated group (haematoma, mean 64.5 vs 36.0 cm3; p=0.021). The unadjusted OR for all-cause 30-day mortality in the PCC group was 0.40 (95% confidence interval, 0.18–0.87; p=0.021) compared to the plasma group. After adjusting for the haematoma volume, bleeding localisation and age, the effect of PCC on mortality became non-significant. In conclusion, treatment with 4-factor PCC for VKA reversal in patients with intracerebral haemorrhage does not seem to reduce the 30-day all-cause mortality compared to plasma.

Abstract
Primary intracerebral hemorrhage (ICH) is a common, devastating disease that lacks an effective specific treatment. Mortality is high, functional outcomes are poor, and these have not substantially changed for decades. There is, therefore, considerable opportunity for advancement in the management of ICH. In recent years, a significant amount of research has begun to address this gap. This article is aimed at updating neurologists on the most clinically relevant contemporary research.

Abstract
Spontaneous non-traumatic intracerebral hemorrhage (ICH) is associated with high morbidity and mortality throughout the world with no proven effective treatment. Majority of hematoma expansion occur within 4 h after symptom onset and is associated with early deterioration and poor clinical outcome. There is a vital role of ultra-early hemostatic therapy in ICH to limit hematoma expansion. Patients at risk for hematoma expansion are with underlying hemostatic abnormalities. Treatment strategy should include appropriate intervention based on the history of use of antithrombotic use or an underlying coagulopathy in patients with ICH. For antiplatelet-associated ICH, recommendation is to discontinue antiplatelet agent and transfuse platelets to those who will undergo neurosurgical procedure with moderate quality of evidence. For vitamin K antagonist-associated ICH, administration of 3-factor or 4-factor prothrombin complex concentrates (PCCs) rather than fresh frozen plasma to patients with INR >1.4 is strongly recommended. For patients with novel oral anticoagulant-associated ICH, administering activated charcoal to those who present within 2 h of ingestion is recommended. Idarucizumab, a humanized monoclonal antibody fragment against dabigatran (direct thrombin inhibitor) is approved by FDA for emergency situations. Administer activated PCC (50 U/kg) or 4-factor PCC (50 U/kg) to patients with ICH associated with direct thrombin inhibitors (DTI) if idarucizumab is not available or if the hemorrhage is associated with a DTI other than dabigatran. For factor Xa inhibitor-associated ICH, administration of 4-factor PCC or aPCC is preferred over recombinant FVIIa because of the lower risk of adverse thrombotic events.

Abstract
BACKGROUND Because patients with warfarin-associated intracerebral hemorrhage (WAICH) have a high risk of ongoing bleeding, disability, and death, urgent coagulopathy reversal should be considered. On the other hand, thromboembolism may occur with reversal or withholding of anticoagulant therapy. The current status of acute hemostatic treatments and clinical outcomes in WAICH patients was investigated. METHODS WAICH patients admitted within 3 days of onset were prospectively enrolled in 10 stroke centers. Thromboembolic and hemorrhagic complications and functional outcomes were followed-up for one year. RESULTS Of 50 WAICH patients (31 men, 73 ± 9 years old) enrolled, all stopped warfarin on admission. Elevated prothrombin time-international normalized ratios (PT-INR) were normalized in 43 (86%). Anticoagulant therapy was resumed with intravenous full-dose unfractionated heparin followed by warfarin in 9 (18%), intravenous low-dose unfractionated heparin followed by warfarin in 14 (28%) and warfarin alone in 14 (28%) at a median of 2.5 (IQR 1.25-9), 4 (2-5.5) and 6 (3-11) days after onset, respectively, after emergent admission. Onset-to-admission time (per 1-hour increase; OR 0.55, 95% CI 0.19-0.84) was inversely associated with hematoma expansion. Anticoagulant therapy was resumed with intravenous full-dose unfractionated heparin in 9 (18%), low-dose heparin in 14 (28%) and warfarin alone in 14 (28%) at a median of 2.5, 4 and 6 days after onset, respectively. During one-year follow-up (n=47), 11 thromboembolic and 6 hemorrhagic complications were documented. Twenty four patients showed unfavorable outcomes, corresponding to a modified Rankin Scale score of 4-6. Thromboembolic complications (OR, 10.62; 95% CI, 1.05-227.85), as well as advanced age (per 1 year; OR, 1.27; 95% CI, 1.10-1.61) and higher National Institutes of Health Stroke Scale (NIHSS) score (per 1 point; OR, 1.24; 95% CI 1.07-1.55), were independently associated with unfavorable outcome. CONCLUSIONS PT-INR normalization on admission and early anticoagulant resumption were common in WAICH patients. Thromboembolic complications were independently associated with unfavorable outcome.

Abstract
Intravenous recombinant tissue plasminogen activator was first approved for the treatment of acute ischemic stroke in the United States in 1996. Thrombolytic therapy has been proven to be effective in acute ischemic stroke treatment and shown to improve long-term functional outcomes. Its use is associated with an increased risk of symptomatic intracerebral hemorrhage as well as orolingual angioedema. Our goal is to outline the management strategies for these postthrombolysis complications.

Abstract
INTRODUCTION Fresh frozen plasma (FFP) is a frequently used human blood product to reverse the effects of vitamin K antagonists. While FFP is relatively economical, its large fluid volume can lead to hospitalization complications, therefore increasing the overall cost of use. MATERIALS & METHODS A recently published article by Sarode et al., in Circulation, described the rate of volume overload associated with FFP use for reversal of vitamin K antagonists. This condition, described as transfusion-associated circulatory overload, has a defined rate of intensive care admission, which also has a well-reported average cost. The additional monetary value of intensive care unit admission and caring for fluid overload is then compared to the cost of another product, four-factor prothrombin complex concentrates, which does not, as per the Sarode paper, result in fluid overload. RESULTS The increased costs attributed to FFP-associated fluid overload for vitamin K antagonist reversal partly defrays the increased upfront cost of four-factor prothrombin complex concentrates. DISCUSSION FFP is commonly used to acutely reverse the effects of vitamin K antagonists. However, its use requires significant time for infusion, may lead to fluid overload, and is not fully effective in compete anticoagulation reversal. One alternative therapy for anticoagulant reversal is use of prothrombin complex concentrates, which are rapidly infused, are not associated with fluid overload, and are effective in complete reversal of coagulation measurements. This should be considered for patients with acute bleeding emergencies.

Use of prothrombin complex concentrate in warfarin anticoagulation reversal in the emergency department: a quality improvement study of administration delays. BMC Health Serv Res 2015; 15:106. [PMID: 25880097 PMCID: PMC4365812 DOI: 10.1186/s12913-015-0775-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2013] [Accepted: 03/02/2015] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Quick reversal of warfarin anticoagulation is important in life threatening bleeding. The aim of this study is to improve the administration delay when using Prothrombin Complex Concentrate (PCC) for the emergent reversal of warfarin anticoagulation in the emergency department. METHODS An audit and feedback quality improvement project was conducted in three phases: a retrospective audit phase, an analysis and feedback phase and prospective evaluation phase. The charts of all eligible patients in a single Emergency Department (ED) in Québec, Canada, who received PCC since the introduction of this product in 2009 until October 31, 2011, were retrospectively audited. The administration delay of PCC was calculated from the time of prescription to the time of administration. With the data, we determined where improvements could be attained, and jointly with all stakeholders in the ED and the blood bank, we created an action plan to ensure the timely administration of PCC. The action plan was then implemented and a six-month prospective evaluation study was conducted to determine any improvement. RESULTS Seventy-seven charts were reviewed in the retrospective chart audit. The mean administration delay was 73.6 minutes (STD [34.1]) with a median of 70.0 minutes (25-75% IQR [45.0-95.0]). We found that this delay was principally due to the following barriers: communication problems between the ED and the blood bank as well as delivery inefficiencies. An action plan that involved a flowchart to remind all clinicians how to order PCC and a new delivery method from the blood bank to the ED were developed. During the 6 months following the implementation of our action plan, 39 patients received PCC and the mean administration time decreased to 33.2 minutes (STD [14.2])(p < .0001) with a median of 30.0 minutes (25-75% IQR [24.3-38.8]). CONCLUSION By implementing an action plan comprising of a flowchart and a new delivery process, this audit and feedback quality improvement project reduced the administration time of PCC by more than half. Future studies to measure the impact of a similar audit and feedback process involving an action plan in other centers should be conducted before this type of quality improvement process is implemented on wider scale.

Abstract
IMPORTANCE Intravenous thrombolysis remains the mainstay treatment for acute ischemic stroke. One of the most feared complications of the treatment is thrombolysis-related symptomatic intracerebral hemorrhage (sICH), which occurs in nearly 6% of patients and carries close to 50% mortality. The treatment options for sICH are based on small case series and expert opinion, and the efficacy of recommended treatments is not well known. OBJECTIVE To provide an overview on the rationale and mechanism of action of potential treatments for sICH that may reverse the coagulopathy before hematoma expansion occurs. EVIDENCE REVIEW Evidence-based peer-reviewed articles, including randomized trials, case series and reports, and retrospective reviews, were identified in a PubMed search on the mechanism of action of intravenous recombinant tissue plasminogen activator and the rationale of various potential treatments using the coagulation cascade as a model. The search encompassed articles published from January 1, 1990, through February 28, 2014. FINDINGS The current treatments may not be sufficient to reverse coagulopathy early enough to prevent hematoma expansion and improve the outcome of thrombolysis-related hemorrhage. CONCLUSIONS AND RELEVANCE Given the mechanism of action of intravenous recombinant tissue plasminogen activator, clinical studies could include agents with a fast onset of action, such as prothrombin complex concentrate, recombinant factor VIIa, and ε-aminocaproic acid, as potential therapeutic options.

Abstract
The increased use of anticoagulants for the prevention and treatment of thromboembolic diseases has led to a rising incidence of anticoagulant-related intracranial hemorrhage (AICH) in the aging western population. High mortality accompanies this form of hemorrhagic stroke, and significant and debilitating long-term consequences plague survivors. Although management guidelines for such hemorrhages are available for the older generation anticoagulants, they are still lacking for newer agents, which are becoming popular among physicians. Supportive care, including blood pressure control, and reversal of anticoagulation remain the cornerstone of acute management of AICH. Prothrombin complex concentrates are gaining popularity over fresh frozen plasma, and reversal agents for newer anticoagulation agents are being developed. Surgical interventions are options fraught with complications, and are decided on a case-by-case basis. Our current state of understanding of this condition and its management is insufficient. This deficit calls for more population-based studies and therapeutic trials to better evaluate risk factors for, and to prevent and treat AICH.

Abstract
Introduction Prothrombin complex concentrate (PCC) and recombinant Factor VIIa (rFVIIa) have been used for emergent reversal of warfarin anticoagulation. Few clinical studies have compared these agents in warfarin reversal. We compared warfarin reversal in patients who received either 3 factor PCC (PCC3) or low-dose rFVIIa (LDrFVIIa) for reversal of warfarin anticoagulation. Methods Data were collected from medical charts of patients who received at least one dose of PCC3 (20 units/kg) or LDrFVIIa (1000 or 1200 mcg) for emergent warfarin reversal from August 2007 to October 2011. The primary end-points were achievement of an INR 1.5 or less for efficacy and thromboembolic events for safety. Results Seventy-four PCC3 and 32 LDrFVIIa patients were analyzed. Baseline demographics, reason for warfarin reversal, and initial INR were equivalent. There was no difference in the use of vitamin K or fresh frozen plasma. More LDrFVIIa patients achieved an INR of 1.5 or less (71.9% vs. 33.8%, p =0.001). The follow-up INR was lower after LDrFVIIa (1.25 vs. 1.75, p < 0.05) and the percent change in INR was larger after LDrFVIIa (54.1% vs. 38.8%, p = 0.002). There was no difference in the number of thromboembolic events (2 LDrFVIIa vs. 5 PCC3, p = 1.00), mortality, length of hospital stay, or cost. Conclusions Based on achieving a goal INR of 1.5 or less, LDrFVIIa was more likely than PCC3 to reverse warfarin anticoagulation. Thromboembolic events were equivalent in patients receiving PCC3 and LDrFVIIa.

Abstract
AIMS There are no data regarding management and outcomes of major bleeding events in patients treated with oral factor Xa inhibitors. METHODS AND RESULTS Using data from ROCKET AF, we analysed the management and outcomes of major bleeding overall and according to the randomized treatment. During a median follow-up of 1.9 years, 779 (5.5%) patients experienced major bleeding at a rate of 3.52 events/100 patient-years with a similar event rate in each arm (n = 395 rivaroxaban vs. n = 384 warfarin). The median number of transfused packed red blood cells (PRBC) per episode was similar in both arms [2 (25th, 75th: 2, 4) units]. Overall, few transfusions of whole blood (n = 14), platelets (n = 10), or cryoprecipitate (n = 2) were used. Transfusion of fresh frozen plasma (FFP) was significantly less in the rivaroxaban arm (n = 45 vs. n = 81 units) after adjustment for covariates [odds ratio (OR) 0.43 (95% CI 0.29-0.66); P < 0.0001]. Prothrombin complex concentrates (PCC) were administered less in the rivaroxaban arm (n = 4 vs. n = 9). Outcomes after major bleeding, including stroke or non-central nervous system embolism (4.7% rivaroxaban vs. 5.4% warfarin; HR 0.89; 95% CI 0.42-1.88) and all-cause death (20.4% rivaroxaban vs. 26.1% warfarin; HR 0.69, 95% CI 0.46-1.04) were similar in patients treated with rivaroxaban and warfarin (interaction P = 0.51 and 0.11). CONCLUSION Among high-risk patients with atrial fibrillation who experienced major bleeding in ROCKET AF, the use of FFP and PCC was less among those allocated rivaroxaban compared with warfarin. However, use of PRBCs and outcomes after bleeding were similar among patients randomized to rivaroxaban or to warfarin.

Abstract
INTRODUCTION Central nervous system (CNS) hemorrhage is a potentially life-threatening condition, especially in patients with acquired coagulopathy. In this setting, treatment of CNS bleeding includes hemostatic therapy to replenish coagulation factors. There is currently a debate over the hemostatic efficacy of plasma in many clinical settings, alongside increasing concern about transfusion-associated adverse events. Despite these concerns, plasma is widely used. Moreover, plasma transfusion practice is variable and there is currently no uniform approach to treatment of traumatic, surgical or spontaneous CNS hemorrhage. This study addresses the need for guidance on the indications and potential risks of plasma transfusion in these settings. An Expert Consensus Panel was convened to develop recommendations guiding the use of plasma to treat bleeding and/or coagulopathy associated with CNS hemorrhage. The panel did not advise on the best treatment available but rather proposed recommendations to be used in the formulation of local procedures to support emergency physicians in their decision-making process. METHODS Evidence was systematically gathered from the literature and rated using methods established by the Scottish Intercollegiate Guidelines Network. The evidence was used to develop graded consensus recommendations, which are presented along with the evidence-based rationale for each in this report. RESULTS Sixty-five articles were identified covering both vitamin K antagonist-anticoagulation reversal and treatment of bleeding/coagulopathy in non-anticoagulated patients. Recommendations were then developed in four clinical scenarios within each area, and agreed on unanimously by all members of the panel. CONCLUSION The Panel considered plasma to be reasonable therapy for CNS hemorrhage requiring urgent correction of coagulopathy, although physicians should be prepared for potential cardiopulmonary complications, and evidence suggests that alternative therapies have superior risk-benefit profiles. Plasma could not be recommended in the absence of hemorrhage or coagulopathy. Consideration of the absolute risks and benefits of plasma therapy before transfusion is imperative.

Abstract
Life-threatening warfarin-associated hemorrhage is common, with a high mortality. In the United States, the most commonly used therapies--fresh frozen plasma and vitamin K--are slow and unpredictable and can result in volume overload. Outside of the United States, prothrombin complex concentrates are often used instead; these pooled plasma products reverse warfarin anticoagulation in minutes rather than hours. This article reviews the literature relating to warfarin reversal with fresh frozen plasma, prothrombin complex concentrates, and recombinant factor VIIa and provides elements for a management protocol based on this literature.

Abstract
Intracerebral hemorrhage (ICH) in patients with oral anticoagulation therapy is an increasingly prevalent problem in large part due to the aging population and the increased use of anticoagulants for patients at high risk of thrombosis. Warfarin has been virtually the only outpatient anticoagulant choice until fairly recently. The development of subcutaneously injected heparinoids, and more recently, of direct thrombin inhibitors, has made the treatment and prognostication of ICH in anticoagulated patients more difficult. In this review, we will review the current state of diagnosis, prognostication, and treatment for patients with this often-devastating type of bleeding. We will focus on warfarin therapy, because the preponderance of evidence comes from studies of warfarin treatment. Where there is evidence, we will contrast warfarin with some of the newer treatment modalities. We review the evidence of the 4 major reversal agents for warfarin, vitamin K, prothrombin complex concentrates, activated factor VII, and fresh frozen plasma as well as rational treatment choices. We offer possible treatments for the newer anticoagulants based on the limited evidence available. Finally, we review recommendations from the major societies and studies that support early and aggressive therapies in intensive care units with dedicated neurological specialists.

Abstract
BACKGROUND Recombinant factor VIIa (rFVIIa) may be used for rapid hemostasis in life-threatening hemorrhage. In warfarin-associated intracerebral hemorrhage (wICH), FVIIa use is controversial and may carry significant thromboembolic risks. We compared incidence of baseline thromboembolic risk factors and thromboembolism rates in wICH patients treated with additional rFVIIa to those treated with standard therapy of fresh frozen plasma (FFP) and vitamin K alone. METHODS We identified 45 consecutive wICH patients treated with additional rFVIIa over 5-year period, and 34 consecutive wICH patients treated with standard therapy alone as comparison group. We compared the incidence of post-hemorrhage cardiac and extra-cardiac thromboembolic complications between two treatment groups, and used logistic regression to adjust for significant confounders such as baseline thromboembolic risk factors. We performed secondary analysis comparing the quantity of FFP transfused between two treatment cohorts. RESULTS Both rFVIIa-treated and standard therapy-treated wICH patients had a high prevalence of pre-existing thromboembolic diseases including atrial fibrillation (73% vs 68%), deep venous thrombosis (DVT) or pulmonary embolism (PE) (22% vs 18%), coronary artery disease (CAD) (38% vs 32%), and abnormal electrocardiogram (EKG) (78% vs 85%). Troponin elevation following wICH was prevalent in both groups (47% vs 41%). Clinically significant myocardial infarction (MI), defined as troponin > 1.0 ng/dL, occurred in 13% of rFVIIa-treated and 6% of standard therapy-treated patients (p=0.52). Past history of CAD (p=0.0061) and baseline abnormal EKG (p=0.02) were independently associated with clinically significant MI following wICH while rFVIIa use was not. The incidences of DVT/PE (2% vs 9%; p=0.18) and ischemic stroke (2% vs 0%; p=0.38) were similar between two treatment groups. Recombinant FVIIa-treated patients had lower mean INR at 3 (p=0.0001) and 6 hours (p<0.0001) and received fewer units of FFP transfusion (3 vs 5; p=0.003). CONCLUSIONS Pre-existing thromboembolic risk factors as well as post-hemorrhage troponin elevation are prevalent in wICH patients. Clinically significant MI occurs in up to 13% of wICH patients. rFVIIa use was not associated with increased incidence of clinically significant MI or other venous or arterial thromboembolic events in this wICH cohort.

Abstract
Spontaneous intracerebral haemorrhage (ICH) is one of the most devastating types of stroke, which has considerable disease burden in "non-white" ethnic groups where the population-attributable risks of elevated blood pressure are very high. Since the treatment of ICH remains largely supportive and expectant, nihilism and the early withdrawal of active therapy influence management decisions in clinical practice. However, approaches to management are now better defined on the basis of evidence that both survival and speed (and degree) of recovery are critically dependent on the location, size, and degree of expansion and extension into the intraventricular system of the haematoma of the ICH. Although no medical treatment has been shown to improve outcome in ICH, several promising avenues have emerged that include haemostatic therapy and intensive control of elevated blood pressure. Conversely, there is continued controversy over the role of evacuation of the haematoma of ICH via open craniotomy. Despite being an established practice for several decades, and having undergone evaluation in multiple randomised trials, there is uncertainty over which patients have the most to gain from an intervention with clear procedural risk. Minimally invasive surgery via local anaesthetic applied drill-puncture of the cranium and infusion of a thrombolytic agent is an attractive option for patients requiring critical management of the haematoma, not just in low resource settings but arguably also in specialist centres of western countries. With several ongoing clinical trials nearing completion, these treatments could enter routine practice within the next few years, further justifying the urgency of "time is brain" and that active management within well-organized, comprehensive acute stroke care units includes patients with ICH.

Abstract
BACKGROUND It has been suggested that antiplatelet or anticoagulant drugs elevate the rate of intracerebral hemorrhage (ICH) in patients with cerebral microbleeds (MBs). To investigate the mechanism by which antiplatelet drugs or warfarin may contribute to deep ICH occurrences in patients with deep MBs, we prospectively analyzed deep ICH occurrences in 807 consecutive patients (351 females and 456 males; mean age ± standard deviation 69.8 ± 12.0 years) who were admitted to our hospital with strokes. METHODS Occurrence-free rate curves were generated using the Kaplan-Meier method; deep ICH occurrence-free rates were compared using the log-rank test. The follow-up period was 0.5 to 71 months (mean ± standard deviation 31.6 ± 22.2 months). RESULTS In patients with deep MBs, the rates (1.0%/year; 6 ICHs in 180 patients) of deep ICH occurrence associated with antiplatelet drugs were not significantly greater than that without the drugs (1.0%/year; 6 ICHs in 167 patients; P = .977). The incidence of deep ICHs associated with warfarin use was not significantly greater than that without warfarin use. CONCLUSIONS Multivariate analysis revealed that the use of antiplatelet drugs or warfarin did not significantly influence the occurrence of deep ICH in patients with deep MBs. Antiplatelet drugs or warfarin did not significantly elevate the rate of deep ICHs in stroke patients with pre-existing deep MBs.

Abstract
PURPOSE OF REVIEW This article provides an update on the latest diagnostic and therapeutic trials relating to the management of intracerebral hemorrhage (ICH). RECENT FINDINGS Early hematoma expansion and worsening cerebral edema may account for delayed neurologic deterioration after ICH. SUMMARY Despite advances in other areas of stroke, there has been no significant improvement in the morbidity and mortality after ICH. The cause of ICH has been shifting from chronic hypertension to other etiologies. Current understanding of the pathophysiologic processes involved with hematoma expansion and the development of secondary injury after ICH has focused the treatment strategies on prevention of these potential complications. Care for the patient after ICH includes basic medical care, prevention of hematoma expansion, and treatment of potential secondary complications. Trials are underway to evaluate the effect of acute blood pressure control on hematoma expansion and the development of cerebral edema. Similarly, new surgical techniques are being explored for clot removal, and medical therapies are being developed to prevent secondary neurotoxic damage.

Abstract
Warfarin, an oral vitamin K antagonist, is used to prevent arterial and venous thromboembolism in patients suffering from a multitude of diseases. In 2004, 31 million warfarin prescriptions were dispensed in the United States. Warfarin inhibits the activation of the vitamin K-dependent clotting factors (Factors II, VII, IX, and X) and regulatory proteins (proteins C, S, and Z). It is one of the leading drugs implicated in emergency room visits for adverse drug reactions. Annually the frequency of bleeding complications associated with overanticoagulation is 15% to 20%, with fatal bleeds measuring as high as 1% to 3%. The most effective method of warfarin reversal involves the use of Four Factor Prothrombin Complex Concentrate (PCC), which is widely used throughout Europe but is unavailable in the United States. The current therapies available to emergency room physicians in the United States are fresh frozen plasma, recombinant Factor VIIa (rFVIIa), Factor Eight Inhibitory Bypassing Activity, or Three Factor PCC concomitantly administered with vitamin K. We review the advantages and disadvantages of these therapies and recommend Three Factor PCC with small doses of rFVIIa and with vitamin K in life-threatening situations if Four Factor PCC is unavailable.

Abstract
Intracerebral hemorrhage (ICH) represents 10-15% of all cerebrovascular events, and is associated with substantial morbidity and mortality. In contrast to ischemic cerebrovascular disease in which acute therapies have proven beneficial, ICH remains a more elusive condition to treat, and no surgical procedure has proven to be beneficial. Aspects pertinent to medical ICH management include cessation or minimization of hematoma enlargement, prevention of intraventricular extension, and treatment of edema and mass effect. Therapies focusing on these aspects include prothrombotic (hemostatic) agents, antihypertensive strategies, and antiedema therapies. Therapies directed towards the reversal of antithrombosis caused by antiplatelet and anticoagulant agents are frequently based on limited data, allowing for diverse opinions and practice styles. Several newer anticoagulants that act by direct thrombin or factor Xa inhibition have no natural antidote, and are being increasingly used for various prophylactic and therapeutic indications. As such, these new anticoagulants will inevitably pose major challenges in the treatment of patients with ICH. Ongoing issues in the management of patients with ICH include the need for effective treatments that not only limit hematoma expansion but also result in improved clinical outcomes, the identification of patients at greatest risk for continued hemorrhage who may most benefit from treatment, and the initiation of therapies during the hyperacute period of most active hemorrhage. Defining hematoma volume increases at various anatomical locations that translate into clinically meaningful outcomes will also aid in directing future trials for this disease. The focus of this review is to underline and discuss the various controversies and challenges involved in the medical management of patients with primary and antithrombotic-related ICH.

Abstract
As new anticoagulants become available, and the number of anticoagulated patients continues to rise, it is necessary to know how to deal with associated bleeding complications. In this review, reversal strategies for traditional anticoagulants (warfarin and heparin) as well as newer anticoagulants are described. Prothrombin complex concentrates (PPCs) can be used to reverse vitamin K antagonists (VKA), and plasma may be used where they are not available. Recombinant activated factor VII (rFVIIa) may be useful to reverse pentasaccharide anticoagulants. 1-Desamino-8-D-arginine vasopressin (DDAVP), cryoprecipitate, PCCs, and dialysis may help to reverse direct thrombin inhibitors, while rFVIIa seems to be ineffective. The effect of direct factor Xa inhibitors may be reversed by PCCs, FVIIa, or factor Xa concentrates.

Abstract
OBJECT Intracerebral hemorrhage (ICH) is the most serious bleeding complication of vitamin K antagonist (VKA) therapy, carrying a high mortality. Rapid reversal of VKA in ICH is critical. Plasma therapy, the standard of care in the US, is not optimal. The ideal prothrombin complex concentrate (PCC) containing all vitamin K-dependent factors (VKDFs) is not available in the US. Therefore, the authors developed a Trauma Coumadin Protocol (TCP) consisting of a 3-factor PCC available in the US (which contains insufficient factor VII [FVII]) with a low-dose recombinant FVIIa to rapidly reverse VKA. METHODS Forty-six patients treated with the TCP were retrospectively analyzed. Fourteen patients had pre- and post-TCP plasma samples collected to assess their VKDF increment. Eleven patients had measurable intraparenchymal hematomas, which were evaluated for expansion. RESULTS The mean pre- and post-TCP international normalized ratios (INRs) were 3.4 (median 2.9) and 1.0 (median 0.9), respectively. Once corrected, INR was maintained at < 1.3 during a patient's hospital stay. The pre-TCP median values of FII, FVII, FIX, and FX were 28%, 21%, 45%, and 20%, respectively; post-TCP median values increased to 144%, 417%, 102%, and 143%, respectively. Four of the 11 patients with measurable intraparenchymal hemorrhage had expansion at 24 hours after TCP. One patient probably (8 hours post-TCP) and 1 patient possibly (3 days post-TCP) had thrombotic complications. CONCLUSIONS The TCP was very effective in rapidly reversing VKA-associated coagulopathy; however, this protocol should be used cautiously in patients at high risk for thrombosis.

Abstract
Study objective The acute management of patients on warfarin with spontaneous or traumatic intracranial hemorrhage continues to be debated in the medical literature. The objective of this paper was to conduct a structured review of the medical literature and summarize the advantages and risks of the available treatment options for reversing warfarin anticoagulation in patients who present to the emergency department with acute intracranial hemorrhage. Methods A structured literature search and review of articles relevant to intracranial hemorrhage and warfarin and treatment in the emergency department was performed. Databases for PubMed, CINAHL, and Cochrane EBM Reviews were electronically searched using keywords covering the concepts of anticoagulation drugs, intracranial hemorrhage (ICH), and treatment. The results generated by the search were limited to English- language articles and reviewed for relevance to our topic. The multiple database searches revealed 586 papers for review for possible inclusion. The final consensus of our comprehensive search strategy was a total of 23 original studies for inclusion in our review. Results Warfarin not only increases the risk of but also the severity of ICH by causing hematoma expansion. Prothrombin complex concentrate is statistically significantly faster at correcting the INR compared to fresh frozen plasma transfusions. Recombinant factor VIIa appears to rapidly reverse warfarin's effect on INR; however, this treatment is not FDA-approved and is associated with a 5% thromboembolic event rate. Slow intravenous dosing of vitamin K is recommended in patients with ICH. The 30-day risk for ischemic stroke after discontinuation of warfarin therapy was 3-5%. The risks of not reversing the anticoagulation in ICH generally outweigh the risk of thrombosis in the acute setting. Conclusions Increasing numbers of patients are on anticoagulation including warfarin. There is no uniform standard for reversing warfarin in intracranial hemorrhage. Intravenous vitamin K in addition to fresh frozen plasma or prothrombin complex concentrate is recommended be used to reverse warfarin-associated intracranial hemorrhage. No mortality benefit for one treatment regimen over another has been shown. Emergency physicians should know their hospital's available warfarin reversal options and be comfortable administering these treatments to critically ill patients.

Abstract
In patients on high-level anticoagulant therapy (prothrombin time-international normalized ratio [PT-INR] ≥ 4.5), surgical procedures can be carried out with bridging therapy using heparin. However, surgical treatment options are severely limited in patients on high-level anticoagulant therapy and who have heparin-induced thrombocytopenia (HIT), as heparin use is contraindicated. We performed tooth extraction using prothrombin complex concentrate (PCC) in 2 HIT patients on high-level anticoagulation therapy (PT-INR ≥ 4.5). Five hundred units of PCC were administered intravenously, and after 15 minutes, it was confirmed that PT-INR was less than 2.0. Tooth extraction was then performed and sufficient local hemostasis was achieved. At 3 hours after tooth extraction, PT-INR was 2.0 or higher and later increased to 4.0 or higher, but postoperative bleeding was mostly absent. When performing tooth extraction in HIT patients on high-level anticoagulant therapy, favorable hemostatic management was achieved through sufficient local hemostasis and transient warfarin reversal using PCC.

Abstract
BACKGROUND Emergency reversal of the international normalized ratio (INR) in patients who develop nontraumatic subdural hemorrhage (SDH) due to oral anticoagulants (OAC) represents a primary treatment strategy but it is difficult to predict the amount of prothrombin complex concentrate (PCC) needed for reversal treatment. Moreover, repeated INR testings in central laboratories (CL) are time consuming. The usefulness of point-of-care INR coagulometers (POC) to test the success of INR reversal in OAC-SDH has not yet been investigated. METHODS Prospectively, INR reversal was performed by administering PCC to patients suffering from acute SDH-OAC using a predefined dosing schedule. Accuracy and time gained by using POC were assessed and compared with CL measurements. RESULTS A total of 10 patients were treated according to the protocol (male: 5). Bland-Altman analysis between POC and CL revealed a mean INR deviation of 0.013 for initial INR values and of 0.081 during reversal treatment. Using POC, the median initial net time gain (accounting for clinical examination and CT) for the start of PCC was 21 min. Median total time for POC-documented reversal was 27 min, as compared to 70 min for CL. The shortest interval between head CT and start of emergency SDH evacuation surgery was 37 min. By employing stepwise POC-guided reversal of the anticoagulatory effect of OAC, the calculated PCC dose could be reduced by 25% in the median. CONCLUSIONS Using POC to measure INR values and patient-adapted PCC administration is a fast and economic method to reverse anticoagulation in patients with acute OAC-SDH.
