Abstract
Administration of acetylsalicylic acid (ASA) at early stage after surgery for spontaneous intracerebral hemorrhage (SICH) may increase the risk of postoperative intracranial bleeding (PIB), because of potential inhibition of platelet function. This study aimed to investigate whether early ASA administration after surgery was related to increased risk of PIB. This retrospective study enrolled SICH patients receiving surgery from September 2019 to December 2022 in seven medical institution. Based on postoperative ASA administration, patients who continuously received ASA more than three days within seven days post-surgery were identified as ASA users, otherwise as non-ASA users. The primary outcome was symptomatic PIB events within seven days after surgery. Incidence of PIB was compared between ASA users and non-ASA users using survival analysis. This study included 744 appropriate patients from 794 SICH patients. PIB occurred in 42 patients. Survival analysis showed no statistical difference between ASA users and non-ASA users in incidence of PIB (P = 0.900). Multivariate Cox analysis demonstrated current smoker (hazard ratio [HR], 2.50, 95%CI, 1.33-4.71, P = 0.005), dyslipidemia (HR = 3.03; 95%CI, 1.31-6.99; P = 0.010) and pre-hemorrhagic antiplatelet therapy (HR = 3.05; 95% CI, 1.64-5.68; P < 0.001) were associated with PIB. Subgroup analysis manifested no significant difference in incidence of PIB between ASA users and non-ASA users after controlling the effect from factors of PIB (i.e., sex, age, current smoker, regular drinker, dyslipidemia, pre-hemorrhagic antiplatelet therapy and hematoma location). This study revealed that early ASA administration to SICH patients after surgery was not related to increased risk of PIB.

Abstract
Intracerebral hemorrhage is a potentially fatal complication in patients with acute leukemia and contributing factors include thrombocytopenia and coagulopathy. Patients with acute leukemia may develop subdural hematoma (SDH) spontaneously or secondary to trauma. In patients with acute leukemia and SDH, the surgical evacuation of the hematoma causes significant morbidity and mortality. New approaches and strategies to reduce the need for surgical evacuation are needed to improve outcomes in patients with acute leukemia and intracerebral hemorrhage. We report two cases of acute SDH in patients with acute leukemia successfully treated with middle meningeal artery embolization, a minimally invasive interventional radiology technique, obviating the need for a surgical intervention. The first patient with acute promyelocytic leukemia (APL) presented with coagulopathy and developed an acute SDH after a fall. The second patient with acute myeloid leukemia presented with gum bleeding and also sustained an acute SDH after a fall. Both patients underwent middle meningeal artery embolization for treating their SDHs while actively receiving induction chemotherapy for acute leukemia. Both patients had resolution of their acute SDH and are in remission from their acute leukemia. Middle meningeal artery embolization is a very effective, and within the context of this setting, a novel, minimally invasive technique for management of SDH in acute leukemia patients, which can prevent the need for surgical interventions with its associated comorbidities and high risk of fatal outcomes in patients with acute leukemia and acute SDH.

Abstract
Introduction Postoperative hemorrhage after adult cranial neurosurgery is a serious complication with substantial morbidity and mortality. Research question We investigated if an extended preoperative screening and an early treatment of previously undetected coagulopathies may decrease the risk of postoperative hemorrhage. Methods A prospective study cohort of patients undergoing elective cranial surgery and receiving the extended coagulatory work-up were compared to a propensity matched historical control cohort. The extended work-up included a standardized questionnaire on the patient's bleeding history as well as coagulatory tests of Factor XIII, von-Willebrand-Factor and PFA-100®. Deficiencies were substituted perioperatively. The primary outcome was determined as the surgical revision rate due to postoperative hemorrhage. Results The study cohort and the control cohort included 197 cases each, without any significant difference in the preoperative intake of anticoagulant medication (p = .546). Most common interventions were resections of malignant tumors (41%), benign tumors (27%) and neurovascular surgeries (9%) in both cohorts. Imaging revealed postoperative hemorrhage in 7 cases (3.6%) in the study cohort and 18 cases (9.1%) in the control cohort (p = .023). Of these, revision surgeries were significantly more common in the control cohort with 14 cases (9.1%) compared to 5 cases (2.5%) in the study cohort (p = .034). Differences in mean intraoperative blood loss were not significant with 528 ml in the study cohort and 486 ml in the control cohort (p = .376). Conclusion Preoperative extended coagulatory screening may allow for revealing previously undiagnosed coagulopathies with subsequent preoperative substitution and thereby reduction of risk for postoperative hemorrhage in adult cranial neurosurgery.

Emergent surgical evacuation of traumatic intracranial hematoma in patients with preoperative thrombocytopenia: surgical risk and early outcome. Acta Neurol Belg 2023; 123:161-171. [PMID: 34426955 DOI: 10.1007/s13760-021-01786-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Accepted: 08/16/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Surgical evacuation of intracranial hematoma, including epidural, subdural, intracerebral, and intraventricular hematoma, is recommended in patients with traumatic brain injury (TBI) for prevention of cerebral herniation and possible saving of life. However, preoperative coagulopathy is a major concern for emergent surgery on patients with severe TBI. METHODS We reviewed 65 consecutive patients with severe TBI who underwent emergency craniotomy for intracranial hematomas. RESULTS Univariate analysis showed preoperative pupil abnormality, absence of pupil light reflex, respiratory failure, preoperative thrombocytopenia (< 100 × 109/L), increased activated partial thromboplastin time (> 36 s), low fibrinogen (< 150 mg/dL), platelet transfusion, red cell concentrate transfusion, and presence of brain contusion and traumatic subarachnoid hemorrhage (SAH) on computed tomography were correlated with poor outcome (death or vegetative state). Multivariate analysis revealed that pupil abnormality (p = 0.001; odds ratio [OR] 0.064, 95% confidence interval [CI] 0.012-0.344), preoperative thrombocytopenia (p = 0.016; OR 0.101, 95% CI 0.016-0.656), and traumatic SAH (p = 0.021; OR 0.211, 95% CI 0.057-0.791) were significant factors. Investigation of the 14 patients with preoperative thrombocytopenia found the emergency surgery was successful, with no postoperative bleeding during hospitalization. However, half of the patients died, and almost a quarter remained in the vegetative state mainly associated with severe cerebral edema. CONCLUSIONS Emergent craniotomy for patients with severe TBI who have preoperative thrombocytopenia is often successful, but the prognosis is often poor. Emergency medical care teams and neurosurgeons should be aware of this discrepancy between successful surgery and poor prognosis in these patients. Further study may be needed on the cerebral edema regulator function of platelets.

Abstract
Background Delirium is characterized by acute brain dysfunction. Although delirium significantly affects the quality of life of patients with brain metastases, little is known about delirium in patients who undergo craniotomy for brain metastases. This study aimed to identify the factors influencing the occurrence of delirium following craniotomy for brain metastases and determine its impact on patient prognosis. Method A total of 153 patients who underwent craniotomy for brain metastases between March 2013 and December 2020 were evaluated for clinical and radiological factors related to the occurrence of delirium. Statistical analysis was conducted by dividing the patients into two groups based on the presence of delirium, and statistical significance was confirmed by adjusting the clinical characteristics of the patients with brain metastases using propensity score matching (PSM). The effect of delirium on patient survival was subsequently evaluated using Kaplan–Meier analysis. Results Of 153 patients, 14 (9.2%) had delirium. Age (P = 0.002), sex (P = 0.007), and presence of postoperative hematoma (P = 0.001) were significantly different between the delirium and non-delirium groups. When the matched patients (14 patients in each group) were compared using PSM, postoperative hematoma showed a statistically significant difference (P = 0.036) between the delirium and non-delirium groups. Kaplan–Meier survival analysis revealed that the delirium group had poorer prognosis (log-rank score of 0.0032) than the non-delirium group. Conclusion In addition to the previously identified factors, postoperative hematoma was identified as a strong predictor of postoperative delirium. Also, the negative impact of delirium on patient prognosis including low survival rate was confirmed.

Abstract
OBJECTIVE Surgical evacuation of chronic subdural hematoma (SDH) in cancer patients is often contraindicated owing to refractory thrombocytopenia. Middle meningeal artery embolization (MMAE) recently emerged as a potential alternative to surgical evacuation for patients with chronic SDH. The goal of this study was to evaluate the safety and efficacy of MMAE for chronic SDH in cancer patients with refractory thrombocytopenia. METHODS A multiinstitutional registry was reviewed for clinical and radiographic outcomes of cancer patients with transfusion-refractory thrombocytopenia and baseline platelet count < 75 K/µl, who underwent MMAE for chronic SDH. RESULTS MMAE was performed on a total of 31 SDHs in 22 patients, with a mean ± SD (range) platelet count of 42.1 ± 18.3 (9-74) K/µl. At the longest follow-up, 24 SDHs (77%) had reduced in size, with 15 (48%) showing > 50% reduction. Two patients required surgical evacuation after MMAE. There was only 1 procedural complication; however, 16 patients (73%) ultimately died of cancer-related complications. Median survival was significantly longer in the 16 patients with improved SDH than the 6 patients with worsened SDH after MMAE (185 vs 24 days, p = 0.029). Length of procedure, technical success rate, SDH size reduction, and complication rate were not significantly differ between patients who underwent transfemoral and transradial approaches. CONCLUSIONS Transfemoral or transradial MMAE is a potential therapeutic option for thrombocytopenic cancer patients with SDH. However, treatment benefit may be marginal for patients with high disease burden and limited life expectancy. A prospective trial is warranted to address these questions.

Abstract
BACKGROUND A paucity of data exists on safe platelet and international normalized ratio (INR) thresholds for hip fracture surgery. Recent work has called into question the safety of preoperative INRs < 1.5 for total knee arthroplasty, and optimal platelet thresholds are unknown. The purpose of this study was to identify the risk of 30-day postoperative morbidity and mortality in patients with thrombocytopenia or elevated INRs undergoing hip fracture surgery. METHODS The National Surgical Quality Improvement Program database was queried for patients undergoing surgical treatment of a native hip fracture from 2012 to 2017 (N = 86,850). Patient demographic, laboratory, and complication data were collected. Patients with preoperative platelet counts or INRs within one day of surgery were included for analysis. Preoperative platelet counts and INRs were divided into four groups (<50 k/μL, ≥50 k to 100 k/μL, ≥100 k to 150 k/μL, ≥150 k/μL, and ≤1.0, >1.0 to 1.5, >1.5 to 2.0, and >2.0, respectively). Multivariable logistic regressions were used to assess the independent association between platelet count and INR on bleeding complications requiring transfusion, wound complications, reoperations, readmissions, and deaths. RESULTS A total of 72,306 and 56,027 patients were included for analysis of preoperative platelet and INR levels, respectively. In reference to platelet levels ≥150 k/μL, a notably increased risk of bleeding events was observed for patients with platelet counts ≥100 k to 150 k/μL (odds ratio [OR] 1.21, 95% confidence interval 1.15 to 1.27), ≥50 to 100 k/μL (OR 1.85, 1.69 to 2.03), and <50 k/μL (OR 1.60, 1.25 to 2.04). Decreasing platelet counts were associated with a stepwise increased risk of mortality from OR 1.12 (1.02 to 1.22) for platelet counts ≥100 k to 150 k/μL to OR 1.63 (1.41 to 1.90) and OR 1.59 (1.06 to 2.39) for platelet counts ≥50 k to 100 k/μL and <50 k/μL, respectively. Elevated INR was associated with an increased risk of reoperations, readmissions, and death (P < 0.001 for all), with largest effect sizes observed starting at INRs >1.5. DISCUSSION The results of this study suggest that preoperative platelet thresholds of <100,000/μL and INR thresholds of 1.5 serve as an important risk factor for complications after hip fracture surgery. Future work is warranted to determine whether preoperative platelet transfusions and/or INR reversal will improve outcomes for these patients. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
Objective The purpose of this study was to assess the risk of hemorrhagic complications in thrombocytopenic patients after Ommaya reservoir placement. Methods Between 2009 and 2017, 192 patients were identified on the National Neoplastic Meningitis Registry and had undergone Ommaya reservoir placement for intrathecal chemotherapy. A retrospective chart review was performed to collect the preoperative and postoperative platelet levels, whether or not the patient received any transfusion of platelets, neurological exams, and whether a postoperative head CT was obtained. Using generally accepted recommendations, a platelet level less than 100,000/μL was considered clinically significant and used as our threshold for thrombocytopenia. Results Seven patients (3.6%) were identified as thrombocytopenic in our patient population with platelet counts ranging from 54,000 to 99,000/μL. Primary diagnoses for the seven patients included leukemia, prostate cancer, primary brain cancer (four patients), and lung cancer (non-small-cell lung carcinoma). One patient received platelet transfusions preoperatively. Three patients had a routine head CT obtained postoperatively with no abnormal findings noted. There were no changes in the neurological exam noted in all of the patients included in this study. No clinically significant hemorrhages were identified in our patients. Conclusions From our single institutional experience, we found that thrombocytopenia is fairly uncommon, found in only 3.6% of our patients undergoing placement of Ommaya reservoirs. We did not encounter any increased risks of postoperative hemorrhage in studied thrombocytopenic patients.

Abstract
OBJECTIVES The goal of this study was to evaluate clinical predictors of abnormal preoperative laboratory values in pediatric neurosurgical patients. METHODS Data obtained in children who underwent a neurosurgical operation were extracted from the prospective National Surgical Quality Improvement Program-Pediatrics (NSQIP-P, 2012-2013) registry. Multivariable logistic regression evaluated predictors of preoperative laboratory values that might require further evaluation (white blood cell count < 2000/μl, hematocrit < 24%, platelet count < 100,000/μl, international normalized ratio > 1.4, or partial thromboplastin time > 45 seconds) or a preoperative transfusion (within 48 hours prior to surgery). Variables screened included patient demographics; American Society of Anesthesiologists (ASA) physical designation classification; comorbidities; recent steroid use, chemotherapy, or radiation therapy; and admission type. Predictive score validation was performed using the NSQIP-P 2014 data. RESULTS Of the 6556 patients aged greater than 2 years, 68.9% (n = 5089) underwent laboratory testing, but only 1.9% (n = 125) had a critical laboratory value. Predictors of a laboratory abnormality were ASA class III-V; diabetes mellitus; hematological, hypothrombotic, or oncological comorbidities; nutritional support; recent chemotherapy; systemic inflammatory response syndrome; and a nonelective hospital admission. These 9 variables were used to create a predictive score, with a single point assigned for each predictor. The prevalence of critical values in the validation population (NSQIP-P 2014) of patients greater than 2 years of age was 0.3% with a score of 0, 1.0% in those with a score of 1, 1.6% in those with a score of 2, and 6.2% in those with a score ≥ 3. Higher score was predictive of a critical value (OR 2.33, 95% CI 1.91-2.83, p < 0.001, C-statistic 0.76) and with the requirement of a perioperative transfusion (intraoperatively or within 72 hours postoperatively; OR 1.42, 95% CI 1.22-1.67, p < 0.001) in the validation population. Moreover, when the same score was applied to children aged 2 years or younger, a greater score was predictive of a critical value (OR 2.47, 95% CI 2.15-2.84, p < 0.001, C-statistic 0.76). CONCLUSIONS Critical laboratory values in pediatric neurosurgical patients are largely predicted by clinical characteristics, and abnormal preoperative laboratory results are rare in patients older than 2 years of age without comorbidities who are undergoing elective surgery. The NSQIP-P critical preoperative laboratory value scale is proposed to indicate patients with the highest odds of an abnormal value. The scale can assist with triaging preoperative testing based on the surgical risk, as determined by the treating surgeon and anesthesiologist.

Postoperative subdural hematoma with blood flow from an epidural hematoma through a tear at the suture point of an artificial dura substitute. Acta Neurochir (Wien) 2019; 161:755-760. [PMID: 30762126 DOI: 10.1007/s00701-019-03830-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Accepted: 01/31/2019] [Indexed: 10/27/2022]
Abstract
OBJECTIVE We have recently seen cases of postoperative epidural and subdural hematomas after duraplasty with an artificial dura substitute. In these cases, the epidural hematoma flowed into the subdural space through a tear at the suture point of the artificial dura substitute. In this study, whether such hematomas are specific to a certain artificial dura substitute was investigated, and the cause and risk factors were examined. METHODS In our institute, 46 patients underwent brain tumor extirpation with duraplasty with an artificial dura substitute; Gore-Tex and SEAMDURA were used as the artificial dura substitutes. Patients with postoperative hemorrhage after brain tumor extirpation with duraplasty with an artificial dura substitute were retrospectively analyzed. Moreover, suture strength was compared experimentally between Gore-Tex and SEAMDURA. RESULTS In patients who underwent brain tumor extirpation with duraplasty with an artificial dura substitute, the rate of postoperative hemorrhage was 8.6%. Epidural and subdural hematomas were seen in four patients after tumor extirpation with duraplasty with SEAMDURA, but there were none with Gore-Tex. Exposure of the superior sagittal sinus at craniotomy, older age, and longer operative time were seen more frequently in patients with hematoma than in patients without hematoma. The strength of the suture point was significantly weaker with SEAMDURA than with Gore-Tex (P = 0.00016). CONCLUSIONS Postoperative epidural and subdural hematomas seem to be specific for SEAMDURA and may be caused by the weak suture strength of SEAMDURA. In cases of duraplasty, a nonabsorbable artificial dura substitute may be suitable.

Abstract
BACKGROUND Reoperation has been increasingly utilized as a metric evaluating quality of care. OBJECTIVE To evaluate the rate of, reasons for, and predictors of unplanned reoperation after craniotomy for tumor in a nationally accrued population. METHODS Patients who underwent cranial tumor resection were extracted from the prospective National Surgical Quality Improvement Program registry (2012-2014). Multivariate logistic regression examined predictors of unplanned cranial reoperation. Predictors screened included patient age, sex, tumor location and histology, functional status, comorbidities, preoperative laboratory values, operative urgency, and time. RESULTS Of the 11 462 patients included, 3.1% (n = 350) underwent an unplanned cranial reoperation. The most common reasons for cranial reoperation were intracranial hematoma evacuation (22.5%), superficial or intracranial surgical site infections (11.9%), re-resection of tumor (8.4%), decompressive craniectomy (6.1%), and repair of cerebrospinal fluid leakage (5.6%). The strongest predictor of any cranial reoperation was preoperative thrombocytopenia (less than 100 000/μL, odds ratio [OR] = 2.51, 95% confidence interval [CI]: 1.23-5.10, P = .01). Thrombocytopenia, hypertension, emergent surgery, and longer operative time were predictors of reoperation for hematoma (P ≤ .004), while dependent functional status, morbid obesity, leukocytosis, and longer operative time were predictors of reoperation for infection (P < .05). Although any unplanned cranial reoperation was not associated with differential odds of mortality (OR = 1.68, 95% CI: 0.94-3.00, P = .08), hematoma evacuation was significantly associated with thirty-day death (P = .04). CONCLUSION In this national analysis, unplanned cranial reoperation was primarily associated with operative indices, rather than preoperative characteristics, suggesting that reoperation may have some utility as a quality indicator. However, hypertension and thrombocytopenia were potentially modifiable predictors of reoperation.

Abstract
Dengue fever (DF) is an arboviral disease caused by a positive-sense RNA virus of the genus Flavivirus. The overall incidence of DF has increased exponentially worldwide over the last three decades. The atypical clinical manifestations of DF grouped under expanded dengue syndrome (EDS), have also been reported more frequently for the last decade. These unusual manifestations are usually associated with coinfections, comorbidities, or complications of prolonged shock. Intracranial hemorrhage (ICH) is one of the rare manifestations of the central nervous system involvement by dengue as a part of EDS. The pathogenesis and treatment of this manifestation also remain controversial. Therefore, we report a case of a previously healthy 65-year-old female who developed ICH as a part of EDS along with a brief review of literature.

Abstract
We present the management of a 15-year-old girl with acute myeloid leukemia who presented with massive hyperleukocytosis and neurological deficit due to intracerebral hemorrhage. Surgical intervention was considered but ultimately not undertaken because of the presence of massive hyperleukocytosis, thrombocytopenia, hypokalemia, and considerable discrepancy between the oxygen saturation values determined mechanically and by peripheral oximetry. Aggressive treatment of the hyperleukocytosis was immediately started, which improved the patient's overall condition and rendered surgical intervention unnecessary. This report shows that immediate treatment of massive hyperleukocytosis and critical interpretation of laboratory results in patients with hyperleukocytosis are warranted.

Abstract
Dengue fever has been a major cause of morbidity and mortality in subtropical and tropical countries. We report a rare case of severe dengue with spontaneous intracranial hemorrhage. A search of literature through PubMed revealed that the largest series analyzed so far only included five cases. A 47-year-old man presented with 7 days history of fever, headache, myalgia, and vomiting with hematemesis. On the day of presentation, he had reduced consciousness and an episode of generalized tonic-clonic seizure. His Glasgow Coma Scale was E1V1M3 with anisocoria. Postresuscitation computed tomography of the brain revealed a right subdural and left thalamic hemorrhage. His blood investigations revealed thrombocytopenia, dengue virus type 1 nonstructural protein antigen test was positive, dengue IgM negative, and dengue IgG positive. A right decompressive craniectomy was done. Unfortunately, the patient died soon after. Spontaneous intracranial hemorrhage in patients with dengue fever is an uncommon entity but usually carry a grave prognosis. To date, there has been no clear management guideline for such cases, as both operative and nonoperative approaches have their own inherent risks.

Abstract
Background: Mild hemophilia without spontaneous bleeding can remain undiagnosed for a lifetime. However, intracranial hemorrhage is one of the most serious complications for patients with hemophilia. In addition, hemorrhagic complications after emergency surgery tend to arise from coagulopathy. Case Description: An 80-year-old man was admitted with left hemiparesis and disturbed consciousness. He had no history of trauma, fever, or drug and alcohol intake. Computed tomography imaging upon admission disclosed a hemispheric subdural hematoma with a midline shift. No vascular abnormalities were identified as a source of the hemorrhage. The hematoma was removed on an emergency basis with external decompression. However, a large subcutaneous hematoma was again evident on the following day. Insufficient hemostatic maneuvers during surgery were considered the cause of this hemorrhagic complication. A second operation was performed to achieve hemostasis of the subcutaneous and muscle tissue. Thereafter, he was rehabilitated without treatment for hemophilia as he had no bleeding episodes. Cranioplasty proceeded using artificial bone at 40 days after the first operation. However, epidural hematoma developed again on postoperative day 1. His neurological status did not worsen so a repeat procedure was unnecessary. Close scrutiny uncovered a diagnosis of mild hemophilia A. Conclusions: Accurate diagnosis is important for the management of postoperative hemorrhagic complications caused by pathologies of the coagulation system. Sufficient hemostasis of hemorrhage from subcutaneous and muscle tissue is essential even during emergency surgery to avoid postoperative complications. A diagnosis of hemophilia should be considered in the face of prolonged activated partial thromboplastin time (APTT).

Abstract
OBJECTIVE We aimed to characterize the occurrence of postoperative hematoma (POH) after neurosurgery overall and according to procedure type and describe the prevalence of possible confounders. METHODS Patient data between 2010 and 2012 at the Department of Neurosurgery in Helsinki University Hospital were retrospectively analyzed. A data search was performed according to the type of surgery including craniotomies; shunt procedures, spine surgery, and spinal cord stimulator implantation. We analyzed basic preoperative characteristics, as well as data about the initial intervention, perioperative period, revision operation and neurologic recovery (after craniotomy only). RESULTS The overall incidence of POH requiring reoperation was 0.6% (n = 56/8783) to 0.6% (n = 26/4726) after craniotomy, 0% (n = 0/928) after shunting procedure, 1.1% (n = 30/2870) after spine surgery, and 0% (n = 0/259) after implantation of a spinal cord stimulator. Craniotomy types with higher POH incidence were decompressive craniectomy (7.9%, n = 7/89), cranioplasty (3.6%, n = 4/112), bypass surgery (1.7%, n = 1/60), and epidural hematoma evacuation (1.6%, n = 1/64). After spinal surgery, POH was observed in 1.1% of cervical and 2.1% of thoracolumbar operations, whereas 46.7% were multilevel procedures. 64.3% of patients with POH and 84.6% of patients undergoing craniotomy had postoperative hypertension (systolic blood pressure >160 mm Hg or lower if indicated). Poor outcome (Glasgow Outcome Scale score 1-3), whereas death at 6 months after craniotomy was detected in 40.9% and 21.7%. respectively, of patients with POH who underwent craniotomy. CONCLUSIONS POH after neurosurgery was rare in this series but was associated with poor outcome. Identification of risk factors of bleeding, and avoiding them, if possible, might decrease the incidence of POH.

Abstract
Coagulopathy is common in intensive care units (ICUs). Many physiologic derangements lead to dysfunctional hemostasis; these may be either congenital or acquired. The most devastating outcome of coagulopathy in the critically ill is major bleeding, defined by transfusion requirement, hemodynamic instability, or intracranial hemorrhage. ICU coagulopathy often poses complex management dilemmas, as bleeding risk must be tempered with thrombotic potential. Coagulopathy associated with intracranial hemorrhage bears directly on prognosis and outcome. There is a paucity of high-quality evidence for the management of coagulopathies in neurocritical care; however, data derived from studies of patients with intraparenchymal hemorrhage may inform treatment decisions. Coagulopathy is often broadly defined as any derangement of hemostasis resulting in either excessive bleeding or clotting, although most typically it is defined as impaired clot formation. Abnormalities in coagulation testing without overt clinical bleeding may also be considered evidence of coagulopathy. This chapter will focus on acquired conditions, such as organ failure, pharmacologic therapies, and platelet dysfunction that are associated with defective clot formation and result in, or exacerbate, intracranial hemorrhage, specifically spontaneous intraparenchymal hemorrhage and traumatic brain injury.

Abstract
INTRODUCTION Dengue fever is a global pandemic threat with increasing incidence. To date, there are no cures and the effectiveness of dengue vaccines is still uncertain. World Heath Organization introduced expanded dengue syndrome to include unusual presentations of dengue fever including severe neurologic complications. One of the deadly complications is intracranial hemorrhage (ICH). METHODOLOGY We collected data of patients with ICH diagnosed via a plain computed tomography of the brain (CT brain) with thrombocytopenia and positive Dengue virus type 1 nonstructural protein (NS1) antigen test or positive dengue serology IgM from January 2014 till June 2015 at our center. Nine patients were included and all 20 other remaining patients reported in literature so far are discussed. DISCUSSION We found that all patients in our center requiring neurosurgical intervention died. Another interesting observation is that detection of Dengue IgG usually meant more severe ICH and poorer outcomes. From our series, platelet levels did not seem to influence the outcome. CONCLUSION We recommend that for early detection of ICH, Dengue IgG should be routinely screened and a high index of suspicion be maintained. Future research should be focused on determining predictors of ICH in patients with dengue fever so that preventive steps can be taken as mortality is high and no treatment seems beneficial at the moment once severe ICH occurs.

Abstract
Objective To describe the characteristics of patients who underwent a cranial operation and postoperatively suffered an intracranial hemorrhage significant enough to require evacuation. Materials & methods 3,109 cranial operations were performed at Houston Methodist Hospital (Texas Medical Center campus) between January 2009 and December 2013. Of these, 59 cases required a second operation for evacuation of an intracranial hemorrhage. The information gathered included the patients’ age, gender, past medical history, medications and laboratory data, initial diagnosis, date/type of first and second operations, duration of hospitalization, discharge condition, and discharge destination. Results The study found a 1.90% rate of a postoperative hemorrhage significant enough to require evacuation after a cranial operation. The average age in the cohort requiring reoperation was 63 +/- 14 years with 42 male and 17 female. Hematoma evacuations were performed at various time intervals depending on the pathology treated at the initial operation. The time to second operation was 2.7 days after intraparenchymal hematoma evacuation, 6.0 days after cerebrovascular surgery, 6.2 days after tumor surgery and 9.7 days after subdural hematoma evacuation. The rate of postoperative hematoma development was 9.1% after a subdural hematoma evacuation, while it was only 1.1% in all other operations. Overall, those requiring hematoma evacuation had a 15% mortality rate, 64% were non-ambulatory, and 54% were discharged to long-term acute care facility, skilled nursing facility, rehabilitation facility or hospice. Conclusions Neurological outcomes were poor in patients who underwent a cranial operation and required a second operation to remove a hematoma. This study suggests close observation of elderly males after a cranial operation, especially after subdural hematoma evacuation, and longer observation time for patients undergoing subdural hematoma evacuation than intraparenchymal hematoma evacuation, tumor surgery or cerebrovascular surgery.

Abstract
OBJECT Postoperative epidural hematoma (EDH), a blood collection between the inserted galeal flap and the overlying skull flap (epigaleal flap hematoma), is a frustrating complication of the surgical treatment of moyamoya disease (MMD) in pediatric patients. The symptoms of postoperative EDH are often similar to those of postoperative cerebral ischemia, and may cause confusion during clinical decision making. The authors designed this study to evaluate the incidence, clinical presentation, risk factors, and treatment outcomes of postoperative EDH in pediatric patients with MMD. METHODS A retrospective review of 148 pediatric patients with 250 craniotomies who underwent indirect bypass revascularization surgery between January 2002 and December 2006 was performed. This group consisted of 60 male and 88 female patients, and the mean age at surgery was 7.5 years (range 1-18 years). RESULTS Of the 250 craniotomies, postoperative EDH was detected in 32 cases. In 12 cases of EDH, surgical treatment was necessary (4.8% of 250 craniotomies). During the same period, 743 non-MMD craniotomy operations were performed. In 6 of these 743 operations, patients developed postoperative EDH that required surgical treatment, significantly less than the percentage of EDH requiring postoperative treatment in patients with MMD (0.8%, p < 0.001). The average interval between craniotomy surgery and the detection of EDH was 1.8 days (range 0-5 days) in patients with MMD and 0.5 days (range 0-2 days; p = 0.018) in the non-MMD craniotomy group. Postoperative EDH was observed in significantly fewer cases (17 of 191) when a subcutaneous drain (SCD) was inserted over the bone flap than in cases in which an SCD was not inserted (14 of 55; p = 0.001). The mean international normalized ratio of prothrombin time in the immediate postoperative blood test was 1.27 ± 0.17 in the EDH group and 1.20 ± 0.11 in the non-EDH group (values are expressed as the mean ± SD; p = 0.008). Central galeal flap tenting suture and immediate postoperative platelet count were not related to the incidence of postoperative EDH following pediatric MMD surgery. CONCLUSIONS Postoperative EDH is more likely to be found following craniotomy in patients with MMD than in those without MMD, and may occur in a delayed fashion. Insertion of an SCD and immediate correction of an abnormal value for international normalized ratio of prothrombin time can decrease the incidence of postoperative EDH following surgery for pediatric MMD.

Abstract
Intracranial meningiomas are mainly benign lesions amenable for surgical resection. However, removal of an intracranial meningioma carries a higher risk of post-operative hemorrhage compared to surgery for other intracranial neoplasms. Because avoidance of post-operative hematoma is of vital interest for neurosurgical patients, the aim of this retrospective study was to analyze risk factors of post-operative hematoma associated with meningioma surgery. Two hundred and ninety six patients with intracranial meningiomas, operated between June 1998 and June 2002, were included in this study. Patients who developed a space-occupying post-operative intracranial hemorrhage and were treated surgically were identified. Data of patients with and without hematoma were retrospectively analyzed to identify risk factors associated with post-operative hematoma. Variables analyzed included patients' age, invasion of venous sinus by the meningioma, tumor vascularization, arachnoidal infiltration, pre-operative prophylaxis of thromboembolic events, peri-operative coagulation abnormalities, residual tumor, location and histology of the tumor. Outcome of patients with post-operative hematoma was assessed according to the Glasgow Outcome Scale (GOS) at discharge and at three months. 21 patients (7.1 %) of 296 patients developed a post-operative intracranial hematoma requiring surgical evacuation. Age was significantly higher in the hematoma group 62.4 +/- 14.0 years compared to patients without post-operative hematoma 56.1 +/- 12.0 (p < 0.05; t-test). Patients older than 70 years had a six-fold increased risk to develop a post-operative hematoma (Chi2 test, 95% CI 1.949-13.224). Patients with post-operative hemorrhage had significant lower post-operative prothrombin time, fibrinogen and platelets immediately after surgery and lower platelets at day 1. None of the other parameters, including pre-operative routine coagulation values, differed significantly between patients with and without post-operative hemorrhage. Three patients with post-operative hematoma showed platelet dysfunction and three patients showed decreased FXIII activity. Of those patients with post-operative hemorrhage at three months follow up three patients (13%) succumbed from reasons not directly related to hemorrhage, one patient remained GOS 2 (4.3%), four patients (17.4%) were GOS 3 and 15 (65.4%) patients had favorable outcome (GOS 4 [one patient] and GOS5 [14 patients]). Meningioma surgery carries a higher risk for post-operative hematoma in the elderly. Thrombocytopenia and other hemostatic disorders were frequently associated with post-operative hemorrhage after meningioma surgery, while no surgical factors could be defined. Extending coagulation tests and specific replacement therapy may prevent hematoma formation and improve the patients outcome.

Abstract
BACKGROUND Abnormalities of the hemostasis can lead to hemorrhage, and on the other hand to thrombosis. Intracranial neoplasms, complex surgical procedures, and head injury have a specific impact on coagulation and fibrinolysis. Moreover, the number of neurosurgical patients on medication (which interferes with platelet function and/or the coagulation systems) has increased over the past years. METHOD The objective of this review is to recall common hemostatic disorders in neurosurgical patients on the basis of the "new concept of hemostasis". Therefore the pertinent literature was searched to provide a structured and up to date manuscript about hemostasis in Neurosurgery. FINDINGS According to recent scientific publications abnormalities of the coagulation system are discussed. Pathophysiological background and the rational for specific (cost)-effective perioperative hemostatic therapy is provided. CONCLUSIONS Perturbations of hemostasis can be multifactorial and maybe encountered in the daily practice of neurosurgery. Early diagnosis and specific treatment is the prerequisite for successful treatment and good patients outcome.

Abstract
May-Hegglin anomaly (MHA) is a rare type of autosomal dominant platelet disorder associated with mutations in the gene encoding nonmuscle myosin heavy chain 9 (MYH9). It is characterized by the presence of large platelets, leukocyte inclusions, and thrombocytopenia. The bleeding tendency is usually mild, but severe hemorrhages have been reported. This is the first reported case of a patient with MHA who underwent craniotomy for intractable seizure disorder of temporal lobe origin. Patients who have thrombocytopenia have a higher likelihood of developing intraoperative or postoperative intracranial hematoma and bleeding complications. The patient was administered desmopressin (DDAVP) prior to the neurosurgical procedure and had no complications. With this approach, the use of platelet concentrates could be avoided. We discuss the role of DDAVP in MHA and related platelet disorders and review the current literature.

Abstract
The authors studied the incidence of postoperative intracranial hematoma to improve care after intracranial surgery. Five years (1995-1999) of surgical records were analyzed retrospectively. Patients were included if evacuation of an intracranial postoperative hematoma was reported. A control group was randomly selected. Forty-nine patients (0.8%) had postoperative hematomas requiring evacuation. The amount of intraoperative blood loss was significantly larger in the hematoma group (762 +/-735 mL [median 500 mL]) than in the control group (415 +/-403 mL; median 300 mL) (P = 0.004). Clinical deterioration occurred within the first 24 hours in 80%, within 6 hours in 51%, and within 1 hour in 12% of the patients. Those who deteriorated within 24 hours had a faster and more life-threatening deterioration than those who had a hematoma after 24 hours. A decreased level of consciousness was found in 61% and increased focal neurologic signs were found in 33% of the patients. An elevated intracranial pressure was seen significantly more often in the hematoma group (9/10 patients, 90%) than in the control group (1/8 patients, 12.5%) (P = 0.001). In this study, a large amount of intraoperative blood loss and elevated intracranial pressure were warning signs of postoperative hematoma and should alert the clinician to the increased risk. Most hematomas occurred within 24 hours after surgery, and in this time period the deterioration was more severe compared with the hematomas that occurred later.

Abstract
Intracerebral hemorrhage is bleeding into the brain parenchyma with possible extension into the ventricles and subarachnoid space. Each year, approximately 37,000 to 52,400 people suffer from intraparenchymal hemorrhage (IPH) in the United States. This rate is expected to rise dramatically in the next few decades as a result of the increasing age of the population and a change in racial demographics. IPH accounts for 8% to 13% of all stroke cases and is associated with the highest mortality rate.

Abstract
Stroke in the postoperative period requires a certain level of sophistication in dealing not only with the patient, but also with the family and significant others. The consultant who is called in to assess the patient must deal with the delicate matter of addressing a presumably unforeseen complication; this often requires political deftness when the surgeon is reluctant to acknowledge that anything possibly could go awry. It is the ultimate hope of all involved that the patient will have a speedy and full recovery. It is important for the patient to be evaluated properly and thoroughly in an effort to prevent a minor, reversible deficit from becoming a major, irreversible neurologic disability. Family members should have all findings and the implications of such findings thoroughly explained to them. Efforts to minimize the potential ramifications of a postoperative stroke generally are not well received and can lead to questions about the integrity of the surgical team as well as the quality of care.

Abstract
Platelet transfusion is indicated when the expected benefits of increasing the number of functional platelets in the patient's circulation outweigh the potential risks generated by exposing the patient to allogeneic, manipulated and stored blood products such as platelet concentrates. Although reassuring evidence has been collected indicating that current risks associated with blood transfusion are lower than those of several voluntary and involuntary human activities, balancing benefits and risks of platelet transfusion may not be easy in a proportion of patients and in a number of conditions. To facilitate this task, guidelines have been developed, with particular attention to cancer patients. As witnessed by the most recent guidelines, over the last few years there has been a progressive, although not absolute, consensus on: (i) the routine use of platelets as a tool to prevent hemorrhage in oncohematology (the so called 'prophylactic approach') as opposed to limiting platelet transfusion to actual bleeding episodes (the so-called 'therapeutic approach') and (ii) lowering the trigger for prophylactic platelet transfusion in stable oncohematology recipients from 20 x 109 to 10 x 109 platelets/L. This has been accompanied by a reduction of platelet use per oncohematology patient of about 20%, an important outcome in view of the progressive increase of platelet demand due to more aggressive therapy in cancer patients. In selected clinical conditions, specific triggers ranging from 30 x 10(9) to 100 x 10(9) platelets/L have been recommended, with higher values when surgical procedures are required for the patient's treatment. Indications and trigger values proposed in the guidelines must be considered within the context of careful clinical evaluation of each patient, with a clear appreciation of the power of discrimination of automated platelet counters at low counts, and of the quality and local availability of platelet products for emergency.

Abstract
There is general consensus that a prophylactic pre-transfusion trigger at 10.000 platelets/microL in stable oncohematological patients is as safe as the traditional trigger of 20.000/microL, and that perioperative triggers at 50.000 and 100.000/microL are adequate in most surgical and neurosurgical conditions respectively. Guidelines on the trigger and other issues related to platelet transfusion can be found in nine documents published during 1987-2001 by the National Institutes of Health (NIH), the British Committee on Standardization in Hematology, the Royal College of Physicians of Edinburgh, the College of American Pathologists, the American Society of Anesthesiology and the American Society of Clinical Oncology (ASCO). Although consensus may be less evident on specific triggers for 'difficult' patients, the following triggers, listed by progressively increasing levels, have been proposed in the literature and have found general agreement: a stable oncohematological recipient: 10.000; lumbar puncture in a stable pediatric leukemic patient: 10.000; thrombocytopenia secondary to gpIIb/IIIa receptor inhibitors [corrected]:10.000; bone marrow aspiration and biopsy: 20.000; gastrointestinal endoscopy in cancer: 20.000-40.000; disseminated intravascular coagulation: 20.000-50.000; fiber-optic bronchoscopy in a bone marrow transplant recipient: 20.000-50.000; neonatal alloimmune thrombocytopenia: 30.000; major surgery in leukemia: 50.000; thrombocytopenia secondary to massive transfusion: 50.000; invasive procedures in cirrhosis: 50.000; cardiopulmonary bypass: 50.000-60.000; liver biopsy: 50.000-100.000; a nonbleeding premature infant: 60.000; neurosurgery: 100.000. The proposed values must be considered within the context of careful clinical evaluation of each individual patient, and attention should be given to the power of discrimination of platelet counters at low counts and to the prompt availability of good quality platelet products in the case of emergency.

Abstract
OBJECT Stereotactic brain biopsy has played an integral role in the diagnosis and management of brain lesions. At most centers, imaging studies following biopsy are rarely performed. The authors prospectively determined the acute hemorrhage rate after stereotactic biopsy by performing immediate postbiopsy intraoperative computerized tomography (CT) scanning. They then analyzed factors that may influence the risk of hemorrhage and the diagnostic accuracy rate. METHODS Five hundred consecutive patients undergoing stereotactic brain biopsy underwent immediate postbiopsy intraoperative CT scanning. Before surgery, routine preoperative coagulation studies were performed in all patients. All medical charts, laboratory results, preoperative imaging studies, and postoperative imaging studies were reviewed. In 40 patients (8%) hemorrhage was detected using immediate postbiopsy intraoperative CT scanning. Neurological deficits developed in six patients (1.2%) and one patient (0.2%) died. Symptomatic delayed neurological deficits developed in two patients (0.4%), despite the fact that the initial postbiopsy CT scans in these cases did not show acute hemorrhage. Both patients had large intracerebral hemorrhages that were confirmed at the time of repeated imaging. The results of a multivariate logistic regression analysis of the risk of postbiopsy hemorrhage of any size showed a significant correlation only with the degree to which the platelet count was below 150,000/mm3 (p = 0.006). The results of a multivariate analysis of a hemorrhage measuring greater than 5 mm in diameter also showed a correlation between the risk of hemorrhage and a lesion location in the pineal region (p = 0.0086). The rate at which a nondiagnostic biopsy specimen was obtained increased as the number of biopsy samples increased (p = 0.0073) and in accordance with younger patient age (p = 0.026). CONCLUSIONS Stereotactic brain biopsy was associated with a low likelihood of postbiopsy hemorrhage. The risk of hemorrhage increased steadily as the platelet count fell below 150,000/mm3. The authors found a small but definable risk of delayed hemorrhage, despite unremarkable findings on an immediate postbiopsy head CT scan. This risk justifies an overnight hospital observation stay for all patients after having undergone stereotactic brain biopsy.

Abstract
The coverage of large surface areas of the brain for electrographic monitoring purposes necessitates a craniotomy to achieve comprehensive sampling. We undertook a review and prospective analysis over 3 years of 38 patients undergoing craniotomy for electrode implantation. The indication for invasive monitoring was to determine candidacy for resective surgery in patients whose seizure focus was not well localized by scalp electroencephalography and other noninvasive testing. Prophylactic cultures from the epidural space were obtained at electrode removal. There were five positive epidural cultures. All five patients went on to seizure-free status. Two positive cultures occurred in patients without obvious infection and who were not treated with antibiotics. Other complications included individual cases of atrial fibrillation, pulmonary edema, postoperative fever, and epidural hematoma. There was no mortality or permanent neurologic morbidity related to craniotomy for electrode placement. There was a 7.9% rate of clinical infection per patient and a 5.7% rate per craniotomy side. This study has identified several factors that significantly correlate with positive epidural culture results: > 100 electrodes, more than ten cables, more than 14 days of implantation, and more than one cable exit site.

Abstract
OBJECTIVE There are few modern data on the complications of surgery for epilepsy from the neurosurgeon's point of view. A survey of complications observed in a large current epilepsy surgery series is presented to facilitate the assessment of a risk:benefit ratio, which must be known when planning for epilepsy surgery and counseling patients. METHODS A series of 429 consecutive patients operated on during 6.5 years in the newly established University of Bonn epilepsy surgery program was, in part, retrospectively, and, in larger part, prospectively analyzed for complications originating from 279 invasive diagnostic procedures and 429 therapeutic procedures. Neuropsychological and psychiatric complications as well as the rate of failure to control seizures are not addressed in this article. RESULTS Two hundred and seventy-nine temporal operations, 59 frontal operations, 22 other extratemporal operations, 33 callosotomies, 3 multilobectomies, and 33 hemispherectomies were performed. Complications were grouped into general surgical and neurological complications. No mortality resulted from 708 invasive procedures. Two hundred and seventy-nine invasive diagnostic procedures (various combinations of strip, grid, and depth electrode insertions) resulted in 3.6% transient morbidity (2.9% surgical complications, 0.7% neurological complications) and 0.7% permanent morbidity (dysphasia). During 429 therapeutic procedures, 33 surgical complications were encountered. None of these resulted in permanent morbidity, except for the necessity for permanent shunt insertion in three patients. Wound infection was the most frequent surgical complication, but we were able to demonstrate a steady decrease during the 6.5-year observation period. The total rate of neurological complications in 429 therapeutic procedures was 5.4%, with 3.03% causing transient morbidity and 2.33% causing permanent morbidity. CONCLUSION Our data indicate that epilepsy surgery can be performed with an acceptable rate of resultant morbidity. The indications for epilepsy surgery, the learning curve determined, and the results from other series are discussed in the light of these figures.
