Abstract
Background Chronic subdural hematomas (CSDHs) usually occur late in adults and older after mild head trauma. Surgical intervention is the first treatment option in CSDH with conservative management being adopted in few cases. Case Description We report a case of a 71-year-old man who presented a spontaneous resolution of a large CSDH. He presented with a difficulty of speech and an ataxic gait. Head (computed tomography scan) showed a low-density lesion located in the right frontal-temporal-parietal region. Conclusion In this report, we discuss the spontaneous resolution of a large CSDH in elderly patients, without surgical intervention. Gradually, several successful nonsurgical therapies for the treatment of these hematomas are reported, although further studies are essential to establish the role of these nonsurgical treatments of CSDHs.

Risk factors of hospital mortality in chronic subdural hematoma: A retrospective analysis of 1117 patients, a single institute experience. J Clin Neurosci 2019; 67:46-51. [PMID: 31213382 DOI: 10.1016/j.jocn.2019.06.026] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Revised: 05/05/2019] [Accepted: 06/09/2019] [Indexed: 12/14/2022]
Abstract
Chronic subdural hematoma (CSDH) is not a benign disease in the elderly, and the mortality of CSDH is reported to be up to 32%. The study aimed to analyze hospital mortality and evaluate the risk factors in patients with CSDH. We retrospectively reviewed all patients with CSDH treated in the neurosurgery department of Renji hospital, School of Medicine, Shanghai Jiao Tong University from 10/2003 to 10/2018. Univariate and multivariate logistic regression analyses on the factors, including gender, age, Glasgow Coma Scale (GCS) on admission, main symptoms, history of head trauma, location of hematoma, density of subdural hematoma, laboratory tests on admission, et al, were performed. A total of 1117 patients with CSDH were included in the study, among which 20 patients died (mortality rate: 1.8%). Comparing the survival group and the death group, gender (p < 0.01), GCS on admission (p < 0.01), impaired consciousness as the presenting symptom (p = 0.041), history of head trauma (p = 0.02), location of hematoma (p = 0.03), platelet (p < 0.01), prealbumin (p = 0.046), albumin (p < 0.01), international normalized rate (INR) (p = 0.03), high sensitivity C-reactive protein (hsCRP) (p < 0.01), postoperative hyperthermia (p < 0.01) were shown to have significance. The logistic regression analysis revealed that GCS on admission (odds ratio [OR] 0.077, p < 0.01), bilateral CSDH (OR 0.100, p < 0.01 left CSDH as reference), prealbumin (OR 0.137, p = 0.02), INR (OR 12.959, p < 0.01) and hsCRP (OR 8.397, p < 0.01) were significantly associated with a higher mortality rate in CSDH. GCS on admission, bilateral CSDH, prealbumin, INR and hsCRP might be independent predictors of CSDH mortality.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is one of the more frequent pathologic entities in daily neurosurgical practice. Historically, CSDH was considered progressive recurrent bleeding with a traumatic cause. However, recent evidence has suggested a complex intertwined pathway of inflammation, angiogenesis, local coagulopathy, recurrent microbleeds, and exudates. The aim of the present review is to collect existing data on pathophysiology of CSDH to direct further research questions aiming to optimize treatment for the individual patient. METHODS We performed a thorough literature search in PubMed, Ovid, EMBASE, CINAHL, and Google scholar, focusing on any aspect of the pathophysiology and nonsurgical treatment of CSDH. RESULTS After a (minor) traumatic event, the dural border cell layer tears, which leads to the extravasation of cerebrospinal fluid and blood in the subdural space. A cascade of inflammation, impaired coagulation, fibrinolysis, and angiogenesis is set in motion. The most commonly used treatment is surgical drainage. However, because of the pathophysiologic mechanisms, the mortality and high morbidity associated with surgical drainage, drug therapy (dexamethasone, atorvastatin, tranexamic acid, or angiotensin-converting enzyme inhibitors) might be a beneficial alternative in many patients with CSDH. CONCLUSIONS Based on pathophysiologic mechanisms, animal experiments, and small patient studies, medical treatment may play a role in the treatment of CSDH. There is a lack of level I evidence in the nonsurgical treatment of CSDH. Therefore, randomized controlled trials, currently lacking, are needed to assess which treatment is most effective in each individual patient.

Out-of-Hospital Triage of Older Adults With Head Injury: A Retrospective Study of the Effect of Adding "Anticoagulation or Antiplatelet Medication Use" as a Criterion. Ann Emerg Med 2017; 70:127-138.e6. [PMID: 28238499 DOI: 10.1016/j.annemergmed.2016.12.018] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2016] [Revised: 12/08/2016] [Accepted: 12/14/2016] [Indexed: 01/09/2023]
Abstract
STUDY OBJECTIVE Field triage guidelines recommend that emergency medical services (EMS) providers consider transport of head-injured older adults with anticoagulation use to trauma centers. However, the triage patterns and the incidence of intracranial hemorrhage or neurosurgery in these patients are unknown. Our objective is to describe the characteristics and outcomes of older adults with head trauma who are transported by EMS, particularly for patients who do not meet physiologic, anatomic, or mechanism-of-injury (steps 1 to 3) field triage criteria but are receiving anticoagulant or antiplatelet medications. METHODS This was a retrospective study at 5 EMS agencies and 11 hospitals (4 trauma centers, 7 nontrauma centers). Patients aged 55 years or older with head trauma who were transported by EMS were included. The primary outcome was the presence of intracranial hemorrhage. The secondary outcome was a composite measure of inhospital death or neurosurgery. RESULTS Of the 2,110 patients included, 131 (6%) had intracranial hemorrhage and 41 (2%) had inhospital death or neurosurgery. There were 162 patients (8%) with steps 1 to 3 criteria. Of the remaining 1,948 patients without steps 1 to 3 criteria, 566 (29%) had anticoagulant or antiplatelet use. Of these patients, 52 (9%) had traumatic intracranial hemorrhage and 15 (3%) died or had neurosurgery. The sensitivity (adjusted for clustering by EMS agency) of steps 1 to 3 criteria was 19.8% (26/131; 95% confidence interval [CI] 5.5% to 51.2%) for identifying traumatic intracranial hemorrhage and 34.1% (14/41; 95% CI 9.9% to 70.1%) for death or neurosurgery. The additional criterion of anticoagulant or antiplatelet use improved the sensitivity for intracranial hemorrhage (78/131; 59.5%; 95% CI 42.9% to 74.2%) and death or neurosurgery (29/41; 70.7%; 95% CI 61.0% to 78.9%). CONCLUSION Relatively few patients met steps 1 to 3 triage criteria. For individuals who did not have steps 1 to 3 criteria, nearly 30% had anticoagulant or antiplatelet use. A relatively high proportion of these patients had intracranial hemorrhage, but a much smaller proportion died or had neurosurgery during hospitalization. Use of steps 1 to 3 triage criteria alone is not sufficient in identifying intracranial hemorrhage and death or neurosurgery in this patient population. The additional criterion of anticoagulant or antiplatelet use improves the sensitivity of the instrument, with only a modest decrease in specificity.

Abstract
OBJECTIVE Prehospital provider assessment of the use of anticoagulant or antiplatelet medications in older adults with head trauma is important. These patients are at increased risk for traumatic intracranial hemorrhage and therefore field triage guidelines recommend transporting these patients to centers capable of rapid evaluation and treatment. Our objective was to evaluate EMS ascertainment of anticoagulant and antiplatelet medication use in older adults with head trauma. METHODS A retrospective study of older adults with head trauma was conducted throughout Sacramento County. All 5 transporting EMS agencies and all 11 hospitals in the county were included in the study, which ran from January 2012 to December 2012. Patients ≥55 years who were transported to a hospital by EMS after head trauma were included. We excluded patients transferred between two facilities, patients with penetrating head trauma, prisoners, and patients with unmatched hospital data. Anticoagulant and antiplatelet use were categorized as: warfarin, direct oral anticoagulants (DOAC; dabigatran, rivaroxaban, and apixaban), aspirin, and other antiplatelet agents (e.g., clopidogrel and ticagrelor). We calculated the percent agreement and kappa statistic for binary variables between EMS and emergency department (ED)/hospital providers. A kappa statistic ≥0.60 was considered acceptable agreement. RESULTS After excluding 174 (7.6%) patients, 2,110 patients were included for analysis; median age was 73 years (interquartile range 62-85 years) and 1,259 (60%) were male. Per ED/hospital providers, the use of any anticoagulant or antiplatelet agent was identified in 595 (28.2%) patients. Kappa statistics between EMS and ED/hospital providers for the specific agents were: 0.76 (95% CI 0.71-0.82) for warfarin, 0.45 (95% CI 0.19-0.71) for DOAC agents, 0.33 (95% CI 0.28-0.39) for aspirin, and 0.51 (95% CI 0.42-0.60) for other antiplatelet agents. CONCLUSIONS The use of antiplatelet or anticoagulant medications in older adults who are transported by EMS for head trauma is common. EMS and ED/hospital providers have acceptable agreement with preinjury warfarin use but not with DOAC, aspirin, and other antiplatelet use.

Comparison of the Outcomes and Recurrence with Three Surgical Techniques for Chronic Subdural Hematoma: Single, Double Burr Hole, and Double Burr Hole Drainage with Irrigation. Korean J Neurotrauma 2015; 11:75-80. [PMID: 27169069 PMCID: PMC4847514 DOI: 10.13004/kjnt.2015.11.2.75] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2015] [Revised: 08/10/2015] [Accepted: 08/28/2015] [Indexed: 12/02/2022] Open
Abstract
Objective Chronic subdural hematoma (CSDH), a disease commonly encountered by neurosurgeons, is treated by burr hole drainage (BHD). However, the optimal surgical technique among the three types of BHD has not been determined. Methods We conducted a retrospective study on BHD performed on 93 patients who were diagnosed with CSDH. The subjects were divided into three groups based on the surgical technique performed: single BHD without irrigation (Group A, n=31), double BHD without irrigation (Group B, n=32), and double BHD with irrigation (Group C, n=30). The clinical factors, radiological factors and recurrences were compared between the three groups. Moreover, independent factors affecting the recurrence were analyzed. Results The change in hematoma thickness was 29.77±7.94%, 49.73±12.87%, and 75.29±4.32% for Group A, B, and C, respectively, while the change in midline shift was 40.81±15.47%, 51.78±10.94%, and 56.16±16.16%, respectively. Thus, Group C showed the most effective for resolution of hematoma and midline shift (p<0.05). Group A, B, and C had 12 cases (38.7%), 8 cases (25.0%), and 3 cases (10.0%) of recurrences, respectively. Group C had a statistically significantly fewer recurrence rate than Group A (p<0.05). Double burr hole, irrigation, and coagulopathy were each identified as independent factors that reduce recurrence (p<0.05). Conclusion Among the three techniques, the double BHD with saline irrigation resulted in the fewest recurrences. It is probably the most effective technique for preventing the recurrence of CSDH.

Abstract
Objective : To characterize patients with chronic subdural hematoma undergoing surgery and to identify prognostic indicators. Methods : We conducted a retrospective analysis of patients diagnosed with chronic subdural hematoma (CSDH) undergoing surgical treatment. We analyzed: age, period from trauma to diagnostic imaging, pre and postoperative Glasgow coma scale, type of surgery, associated comorbidities, use of postoperative drainage and outpatient treatment. Results : The sample consisted of 176 patients, 126 male and 50 female patients (ratio 2.5 : 1), ages ranged from six months to 97 years, with an average of 59.3 years. CSDH was caused by trauma in 52% of patients, with the time from trauma to imaging averaging 25.05 days; 37.7% were hypertensive patients and 20% had a neurological disease. Eighty-five (48.3%) patients were elderly and altered consciousness was present in 63% of cases. Of the 91 (51.7%) non-elderly patients, 44% presented with headache, altered consciousness occurred in 40% and motor abnormalities in 27.5%. The CSDH was located on the right in 41%, left in 43% and bilaterally in 16% of patients. Conclusion : the change of consciousness was the most common clinical alteration in the elderly and headache in non-elderly. The most associated comorbidity was the arterial hypertension and the most frequent cause, head trauma. The trepanation with two oriffices associated with a closed drainage system was the most used operating, with high efficacy and low complication rate.

Abstract
STUDY OBJECTIVE The objective was to compare neurological outcomes at 6 months in older patients with preinjury warfarin or clopidogrel use and mild traumatic intracranial hemorrhage with those without prior use of these medications. METHODS This was a retrospective study conducted at a Level 1 trauma center from April 2009 to July 2010. Patients older than 55 years with isolated mild head injury (Glasgow Coma Scale score 13-15 and Abbreviated Injury Score < 3 in nonhead body region) were included. Demographic, clinical, and outcome data were abstracted from an existing traumatic brain injury database. The primary end point of unfavorable extended Glasgow Outcome Score at 6 months was compared between patients with and without preinjury warfarin or clopidogrel use. RESULTS Seventy-seven eligible patients were identified: 27 (35%) with preinjury warfarin or clopidogrel use and 50 (65%) without. Baseline characteristics (sex, Glasgow Coma Scale score, Injury Severity Score, computed tomography score, and in-hospital mortality) were similar between cohorts, although the preinjury warfarin or clopidogrel cohort was older than the control group (P < .05). Patients in the preinjury warfarin or clopidogrel cohort were more likely to have an unfavorable outcome (16/27; 59.3%; 95% confidence interval, 40.7%-77.8%) as compared with those without (18/50; 36.0%; 95% confidence interval, 22.7%-49.3%) (P = .05). CONCLUSION Older adults with preinjury warfarin or clopidogrel use and mild traumatic intracranial hemorrhage may be at an increased risk for unfavorable long-term neurological outcomes compared with similar patients without preinjury use of these medications.

Abstract
BACKGROUND Chronic subdural hematomas (CSDHs) are common in neurosurgical practice. There are no publications that report large series of the epidemiological characteristics of this pathology in Brazil. The purpose is to describe a large series of surgical cases and analyze the epidemiological and clinical characteristics. METHODS We retrospectively analyzed patients with CSDH admitted into Neurosurgical Services at the Hospital de Base do Distrito Federal, Brasília, Brazil from 2006 to 2011. Age, sex, clinical feature, etiology, surgical procedure, side, clinical outcome, and recurrence were reviewed. Statistical tests were used to analyze data, and P < 0.05 was considered statistically significant. RESULTS The series included 778 patients. There were 643 (82.6%) male patients with a mean age of 64.3 ± 15.9 (range, 14-93) years. The principal symptom was headache (58.9%). The most frequent origin was a fall (282 cases, 36.2%), but the origin remained unclear in 281 (36.1%) patients. Mild head injury occurred in 540 (69.4%) cases. Burr holes with drainage were used as the surgical procedure in 96.5% patients, and 687 (88.3%) patients had a positive outcome. Mortality was 0%. Recurrence was observed in 42 cases. CONCLUSIONS The occurrence of CSDHs is more common in elderly men. Treatment with burr holes and drainage is a simple and safe method for treatment. In our experience, CSDH presents decreased morbidity and mortality.

Abstract
OBJECTIVES Appropriate use of cranial computed tomography (CT) scanning in patients with mild blunt head trauma and preinjury anticoagulant or antiplatelet use is unknown. The objectives of this study were: 1) to identify risk factors for immediate traumatic intracranial hemorrhage (tICH) in patients with mild head trauma and preinjury warfarin or clopidogrel use and 2) to derive a clinical prediction rule to identify patients at low risk for immediate tICH. METHODS This was a prospective, observational study at two trauma centers and four community hospitals that enrolled adult emergency department (ED) patients with mild blunt head trauma (initial ED Glasgow Coma Scale [GCS] score 13 to 15) and preinjury warfarin or clopidogrel use. The primary outcome measure was immediate tICH, defined as the presence of ICH or contusion on the initial cranial CT. Risk for immediate tICH was analyzed in 11 independent predictor variables. Clinical prediction rules were derived with both binary recursive partitioning and multivariable logistic regression. RESULTS A total of 982 patients with a mean (± standard deviation [SD]) age of 75.4 (±12.6) years were included in the analysis. Sixty patients (6.1%; 95% confidence interval [CI] = 4.7% to 7.8%) had immediate tICH. History of vomiting (relative risk [RR] = 3.53; 95% CI = 1.80 to 6.94), abnormal mental status (RR = 2.85; 95% CI = 1.65 to 4.92), clopidogrel use (RR = 2.52; 95% CI = 1.55 to 4.10), and headache (RR = 1.81; 95% CI = 1.11 to 2.96) were associated with an increased risk for immediate tICH. Both binary recursive partitioning and multivariable logistic regression were unable to derive a clinical prediction model that identified a subset of patients at low risk for immediate tICH. CONCLUSIONS While several risk factors for immediate tICH were identified, the authors were unable to identify a subset of patients with mild head trauma and preinjury warfarin or clopidogrel use who are at low risk for immediate tICH. Thus, the recommendation is for urgent and liberal cranial CT imaging in this patient population, even in the absence of clinical findings.

Abstract
BACKGROUND To present the accumulated experience from treating chronic subdural hematomas (CSDH) in a local hospital of a third world country. METHODS One hundred and twenty-five consecutive patients with CSDH who were surgically treated in the Neurosurgical Department of the Hospital da Restauração, Recife-PE, Brazil, between January 2006 and May 2008, were retrospectively studied. Glasgow Outcome Scale (GOS) was employed to define outcome at 6 months as good (GOS 4 and 5) or poor (GOS ≤ 3). Age, admission Glasgow Coma Scale (GCS), location of hematomas (unilateral/bilateral), drainage system placement and recurrence were all analyzed for potential impact on final outcome. RESULTS The median age was 69 years, with a male/female ratio of 102/23. History of trauma was present in 60.8% of the patients. The median GCS on admission was 14. In 64 patients, the hematoma was on the left side, while in 42 patients it was on the right side. Bilateral hematomas were present in 19 cases (15.2%). Drainage systems were used in 93.6% of the cases. Recurrence occurred in 8.8% of the patients. One hundred and three patients obtained a good outcome at 6 months. The mortality rate was 11.2%. Patients with GCS ≥9 on admission presented better outcome (P < 0.05). Recurrent cases presented a poor outcome (P < 0.05). CONCLUSIONS This study suggests that the main factors associated with outcome in patients harboring CSDH are the admission GCS score and the recurrence status. Advanced age is not a contraindication for surgical treatment. This study, solely focused on the Brazilian population, is the first of its kind in the English literature, and it could serve as a useful introduction to a more complex, multivariate, debate.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is commonly seen in neurosurgical practice, and the incidence is increasing. Treatment results are highly variable with respect to recurrences and complications. OBJECTIVE To report our single-center experience with the surgical treatment of CSDH in patients on preoperative corticosteroids and to assess possible predictors of outcome. METHODS The medical reports of 496 consecutive patients with CSDHs treated with burr hole craniostomy were analyzed retrospectively. Patient demographics, medication, hematoma, treatment characteristics, and laboratory values were scored in relation to outcome. Data were analyzed with the χ(2) test, independent t test, and multivariate backward regression. RESULTS Mean age was 71.5 ± 13.3 years (range, 18.6-95.4 years); the male-to-female ratio was 3:1. A decreased Glasgow Coma Scale (GCS) was observed in 63.1%, and GCS motor score on admission was < 6 in 25.2%. Recurrence and mortality rates were 11.9% and 5.3%, respectively. Multivariate analysis showed a longer period of preoperative dexamethasone administration (odds ratio [OR], 0.93 per day; P = .02), GCS motor score within 1 week after surgery of 6 (OR, 0.54; P = .02), postoperative complications (OR, 5.3; P < .001), and a left-sided hematoma (OR, 0.42; P = 0.010) to be significantly related to recurrence risk. CONCLUSION The present data suggest that in surgical treatment of CSDH with burr hole craniostomy, extended preoperative corticosteroid administration is associated with a lower recurrence rate. The use of corticosteroids does not seem to be related to a higher incidence of complications and treatment-related death compared with the current literature.

Abstract
The main aim of this study was to investigate the influence of perioperative anticoagulation on the clinical course and outcome of 144 patients who underwent surgery for chronic subdural hematoma (CSDH). The outcome was categorized according to the modified Rankin Scale (mRS), Barthel Index and postoperative quality of life (QoL) scale. There was a significant correlation between preoperative aspirin medication and reoperation (Mann-Whitney U-test, p<0.05). Moreover, dosage and duration of postoperative low-molecular-weight heparin (LMWH) administration were associated with a higher risk of reoperation (Mann-Whitney U-test, p<0.01) and a worse outcome on the mRS (Mann-Whitney U-test, p<0.05). Intraoperative treatment with prothrombin complex concentrate led to a poor outcome on the mRS (Craddock-Flood test, p<0.05). Reoperation is the strongest predictive factor of a poor QoL after surgical treatment of CSDH. Both preoperative and postoperative anticoagulation treatment may affect reoperation rate and, thus, postoperative QoL.

Abstract
OBJECTIVES The objective was to compare outcomes in emergency department (ED) patients with preinjury warfarin use and traumatic intracranial hemorrhage (tICH) who did and did not receive recombinant activated factor VIIa (rFVIIa) for international normalized ratio (INR) reversal. METHODS This was a retrospective before-and-after study conducted at a Level 1 trauma center, with data from 1999 to 2009. Eligible patients had preinjury warfarin use and tICH on cranial computed tomography (CT) scan. Patients before (standard cohort) and after (rFVIIa cohort) implementation of a protocol for administering 1.2 mg of rFVIIa in the ED were reviewed. Glasgow Coma Scale (GCS) score, Revised Trauma Score (RTS), Injury Severity Score (ISS), INR, and Marshall score were collected. Outcome measures included mortality, thromboembolic complications, and INR normalization. RESULTS Forty patients (median age=80.5 years, interquartile range [IQR]=63.5-85) were included (20 in each cohort). Age, GCS score, ISS, RTS, initial INR, and Marshall score were similar (p>0.05) between the two cohorts. Survival was identical between cohorts (13 of 20, or 65.0%, 95% confidence interval [CI]=40.8% to 84.6%). There were no differences in rate of thromboembolic complications in the standard cohort (1 of 20, 5.0%, 95% CI=0.1% to 24.9%) than the rFVIIa cohort (4 of 20, 20.0%, 95% CI=5.7% to 43.7%; p=0.34). Time to normal INR was earlier in the rFVIIa cohort (mean=4.8 hours, 95% CI=3.0 to 6.7 hours) than in the standard cohort (mean=17.5 hours, 95% CI=12.5 to 22.6; p<0.001). CONCLUSIONS In patients with preinjury warfarin and tICH, use of rFVIIa was associated with a decreased time to normal INR. However, no difference in mortality was identified. Use of rFVIIa in patients on warfarin and tICH requires further study to demonstrate important patient-oriented outcomes.

Abstract
PURPOSE OF REVIEW Recombinant factor VIIa (rFVIIa) and thromboelastography have acquired increasing importance in patients with severe bleeding and coagulopathy. This article reviews the current opinions regarding their use, with the purpose of clarifying the ambiguities that exist in dealing with trauma patients. RECENT FINDINGS Recent evidence encourages the early use of rFVIIa and thromboelastography in the severe trauma patient with hemorrhagic shock, as a component of the damage control strategy. rFVIIa may decrease short-term mortality and the rate of required blood components during resuscitation, with no apparent increase in thromboembolic complications. Thromboelastometry enables better and earlier recognition of the coagulopathy accompanying such trauma patients. In patients with traumatic brain injury and coagulopathy, rFVIIa may delay or even halt the need for surgery, with no proven decrease in mortality. In those who needed urgent neurosurgical intervention, rFVIIa may rapidly correct the coagulopathy, enabling earlier and safer surgical intervention. SUMMARY Thromboelastometry may guide the medical staff when and to whom rFVIIa could be administered. Evidence also encourages the use of rFVIIa in traumatic brain injury. More research is required to prove decreases in mortality using both thromboelastography and rFVIIa in trauma, with a focus on clear end points and goal-directed therapy.

Coagulopathic patients with traumatic intracranial bleeding: defining the role of recombinant factor VIIa. ACTA ACUST UNITED AC 2008; 63:725-32.

Abstract
BACKGROUND The combination of coagulopathy and intracranial bleeding (ICB) is a well-recognized cause of morbidity and mortality in the neurosurgical patient because of the risk of hematoma expansion. Although recombinant factor VIIa (rFVIIa) has been shown to be useful in intracerebral hemorrhage, its use in other forms of ICB such as subdural hematomas (SDHs) has rarely been described. METHODS The clinical and laboratory features of a prospectively followed up case-series of 15 patients with traumatic ICB (mainly isolated SDHs) and coagulopathy international normalized ratio (INR) >1.3 treated with rFVIIa in our institution are presented, along with a review of the literature regarding the role of rFVIIa in neurosurgical patients with ICB. RESULTS All 15 patients suffered a SDH (4 of 15 had a combined ICB) and coagulopathy (mean INR, 2.34 +/- 0.83; thrombocytopenia rate, 20%), which was attributed to anticoagulants in 46.7%. The mean INR decreased to 1.5 +/- 0.14 after standard therapy and 0.92 +/- 0.1 after rFVIIa therapy. There was no evident progression of bleeding in any patient treated with rFVIIa. In three patients, neurosurgery was obviated by rFVIIa therapy, whereas the other 12 patients underwent neurosurgery safely and successfully. None required subsequent surgery for continuing hemorrhage, and no adverse events secondary to FVIIa administration were observed. Based on our experience and the reviewed literature, a proposed algorithm for a stratified approach to rFVIIa administration in traumatic ICB is discussed. CONCLUSIONS rFVIIa is an inducer of hemostasis, which successfully controlled potentially devastating bleeding in all of 15 coagulopathic neurosurgical patients with ICB. The use of rFVIIa lowered the INR into the operable range in all patients, allowing surgery, and in some cases, obviated the need for surgery. Randomized, placebo-controlled clinical trials are needed to further assess the efficacy and cost-effectiveness of this approach in this setting.
