ABSTRACT
There is an increased risk of stroke and other neurological complications in human immunodeficiency virus (HIV) infected patients with no large population-based studies in the literature. We aim to evaluate the prevalence of stroke, HIV-associated neurological complications, and identify risk factors associated with poor outcomes of stroke among HIV admissions in the United States. In the nationwide inpatient sample with adult HIV hospitalizations, patients with primary cerebrovascular disease (CeVDs) and HIV-associated neurological complications were identified by ICD-9-CM codes. We performed a retrospective study with weighted analysis to evaluate the prevalence of stroke and neurological complications and outcomes of stroke among HIV patients. We included 1,559,351 HIV admissions from 2003 to 2014, of which 22470 (1.4%) patients had CeVDs (transient ischemic attack [TIA]: 3240 [0.2%], acute ischemic stroke [AIS]: 14895 [0.93%], and hemorrhagic stroke [HS]: 4334 [0.27%]), 7781 (0.49%) had neurosyphilis, 29,925 (1.87%) meningitis, 39,190 (2.45%) cytomegalovirus encephalitis, 4699 (0.29%) toxoplasmosis, 9964 (0.62%) progressive multifocal leukoencephalopathy, and 142,910 (8.94%) epilepsy. There is increased overall prevalence trend for CeVDs (TIA: 0.17%-0.24%; AIS: 0.62%-1.29%; HS: 0.26%-0.31%; pTrend < .0001) from 2003 to 2014. Among HIV admissions, variables associated with AIS were neurosyphilis (odds ratio: 4.38; 95% confidence interval: 3.21-5.97), meningitis (4.87 [4.10-5.79]), and central nervous system tuberculosis (6.72 [3.85-11.71]). Toxoplasmosis [4.27 [2.34-7.76]), meningitis (2.91 [2.09-4.06)], and cytomegalovirus encephalitis (1.62 [1.11-2.37]) were associated with higher odds of HS compared to patients without HS. There was an increasing trend of CeVDs over time among HIV hospitalizations. HIV-associated neurological complications were associated with the risk of stroke, together with increased mortality, morbidity, disability, and discharge to long-term care facilities. Further research would clarify stroke risk factors in HIV patients to mitigate adverse outcomes.

BACKGROUND AND OBJECTIVES: The Studies have suggested hypercholesterolemia is a risk factor for cerebrovascular disease. However, few of the studies with a small number of patients had tested the effect of hypercholesterolemia on the outcomes and complications among acute ischemic stroke (AIS) patients. We hypothesized that lipid disorders (LDs), though risk factors for AIS, were associated with better outcomes and fewer post-stroke complications. MATERIALS AND METHOD: We performed a retrospective analysis of the Nationwide Inpatient Sample (years 2003-2014) in adult hospitalizations for AIS to determine the outcomes and complications associated with LDs, using ICD-9-CM codes. In 2014, we also aimed to estimate adjusted odds of AIS in patients with LDs compared to patients without LDs. The multivariable survey logistic regression models, weighted to account for sampling strategy, were fitted to evaluate relationship of LDs with AIS among 2014 hospitalizations, and outcomes and complications amongst AIS patients from2003-2014. RESULTS AND CONCLUSIONS: In 2014, there were 28,212,820 (2.02% AIS and 5.50% LDs) hospitalizations. LDs patients had higher prevalence and odds of having AIS compared with non-LDs. Between 2003-2014, of the total 4,224,924 AIS hospitalizations, 451,645 (10.69%) had LDs. Patients with LDs had lower percentages and odds of mortality, risk of death, major/extreme disability, discharge to nursing facility, and complications including epilepsy, stroke-associated pneumonia, GI-bleeding and hemorrhagic-transformation compared to non-LDs. Although LDs are risk factors for AIS, concurrent LDs in AIS is not only associated with lower mortality and disability but also lower post-stroke complications and higher chance of discharge to home.

BACKGROUND: The current guidelines do not recommend increasing the dose of intravenous recombinant tissue plasminogen activator (IV rt-PA) for ischemic stroke patients weighing >100 kg. Obese patients are therefore receiving an IV rt-PA dose <0.9 mg/kg; however, the consequences of such underdosing are unknown. Our goal was to determine the relationship between obesity and clinical outcomes among acute ischemic stroke patients receiving IV rt-PA. METHODS: Data from all patients admitted to US hospitals between 2002 and 2009 who were treated with IV thrombolysis and who had a primary discharge diagnosis of stroke were included. The effect of obesity on rates of intracerebral hemorrhage and discharge outcomes was analyzed after adjusting for potential confounders using logistic regression analysis. RESULTS: Of the 81,579 patients with ischemic stroke treated with IV rt-PA, 5174 (6.3%) were categorized as obese. The intracerebral hemorrhage rates in obese and nonobese patients were significantly different (4.5% v 6.3%; P = .01). After adjusting for age, sex, presence of hypertension, diabetes mellitus, location/teaching status and All Patient Refined Diagnosis Related Group severity scale, there was no difference in the rates of no to minimal disability between obese and nonobese patients (odds ratio [OR] 1.0; 95% confidence interval [CI] 0.8-1.2; P = .8). Obese patients had lower odds of in-hospital mortality (OR 0.6; 95% CI 0.5-0.8; P = .001) but also more likely to be discharged with moderate to severe disability (OR 1.2; 95% CI 1.01-1.3; P = .03). CONCLUSIONS: Obese patients receiving IV rt-PA treatment for acute ischemic stroke appear to have a higher survival rate most likely related to their decreased rates of intracerebral hemorrhage.

BACKGROUND: Due to pro-inflammatory and hypercoagulation states, COVID-19 infection is believed to increase the risk of stroke and worsen the outcomes of the patients having pre-existing cerebrovascular diseases (CeVD). There is limited literature on prevalence of pre-existing CeVD in COVID-19 patients, and outcomes are unknown. The objective of this meta-analysis is to evaluate the outcomes of COVID-19 patients with pre-existing CeVD. METHODS: English full-text-observational studies having data on epidemiological characteristics of COVID-19 patients were identified searching PubMed, Web of Science, and Scopus using MeSH-terms COVID-19 OR coronavirus OR SARS-CoV-2 OR 2019-nCoV from December 1, 2019 to April 30, 2020. Studies having CeVD or stroke as one of the pre-existing comorbidities and described outcomes including intensive care unit (ICU) admission, mechanical ventilation utilization, and mortality were selected with consensus of three reviewers. Following MOOSE protocol, 11 studies were included. The pooled prevalence of CeVD and outcomes were calculated. Meta-regression was performed, and correlation coefficient (r) and odds ratio (OR) were estimated to evaluate the effects of pre-existing CeVD on outcomes of COVID-19 patients. Meta-analysis with random-effects model was used to calculate OR along with its 95% CI from the studies containing data on composite poor outcome. RESULTS: Out of 8/11 studies showing data on mortality and mechanical ventilation, and 7/11 on ICU admission, pooled prevalence of pre-existing CeVD was 4.4% (244/4987). In age-adjusted meta-regression analysis, pre-existing CeVD was associated with ICU admission [r: 0.60; OR: 1.82 (1.25-2.69)], mechanical ventilation [r: 0.29; OR: 1.33 (1.09-1.63)], and mortality [r: 0.35; OR: 1.42 (1.14-1.77)] amongst COVID-19 hospitalizations. 9/11 studies reported data on binary composite outcomes, the pooled prevalence of pre-existing CeVD was 4.3% (155/3603) and 7.46% (83/1113) amongst COVID-19 hospitalizations and COVID-19 hospitalization-related poor outcomes, respectively. In meta-analysis, COVID-19 patient with pre-existing CeVD had 2.67-fold (1.75-4.06) higher odds of poor outcomes. CONCLUSION: COVID-19 patients with pre-existing cerebrovascular disease have poor outcomes and extra precautions should be taken in managing such patients during the ongoing pandemic.

BACKGROUND: Pediatric stroke is a debilitating disease. There are several risk factors predisposing children to this life-threatening disease. Although, published literature estimates a relatively high incidence of pediatric stroke, treatment guidelines on intravenous tissue plasminogen activator and endovascular thrombectomy utilization remain a dilemma. There is a lack of large population-based studies and clinical trials evaluating the efficacy and safety outcomes associated with these treatments in this unique population. AIM: We sought to determine the prevalence of risk factors, concurrent utilization of intravenous tissue plasminogen activator and endovascular thrombectomy, and associated outcomes in pediatric stroke hospitalizations. METHODS: We performed a retrospective analysis of the Nationwide Inpatient Sample data (2003-2014) in pediatric (1-21 years of age) acute ischemic stroke hospitalizations using ICD-9-CM codes. The multivariable survey logistic regression model was weighted to account for sampling strategy, evaluate predictors of hemorrhagic conversion, and treatment outcomes (mortality, morbidity, and discharge disposition) amongst pediatric stroke hospitalizations. RESULTS: In this analysis, 9109 patients between 1 and 21 years of age were admitted during 2003-2014 for acute ischemic stroke. Of these 9109 patients, 119 (1.30%) received endovascular thrombectomy alone, 256 (2.82%) intravenous recombinant tissue plasminogen activator, and 69 (0.75%) both endovascular thrombectomy and intravenous recombinant tissue plasminogen activator. We found overall high prevalence of conditions like epilepsy (19.59%), atrial septal defect (11.76%), sickle cell disease (8.63%), and moyamoya disease (5.41%) in pediatric acute ischemic stroke patients. Unadjusted analysis showed high prevalence of all-cause in-hospital mortality in combined endovascular thrombectomy and intravenous recombinant tissue plasminogen activator utilization group, and higher prevalence of hemorrhagic conversion and morbidity in endovascular thrombectomy utilization group compared to other groups (p < 0.0001). Multivariate adjusted analysis showed that children with endovascular thrombectomy utilization (aOR: 19.19; 95% CI: 2.50-147.29, p = 0.005), intravenous recombinant tissue plasminogen activator utilization (aOR: 8.85; 95% CI: 1.92-40.76, p = 0.005), and both (endovascular thrombectomy and intravenous recombinant tissue plasminogen activator) utilization (aOR: 7.55; 95% CI: 1.16-49.31, p = 0.035) had higher odds of hemorrhagic conversion compared to no-treatment group. CONCLUSION: We found various risk factors associated with pediatric stroke. The early identification can be useful to formulate preventive strategies and influence the incidence of pediatric stroke. Our study results showed that use of intravenous recombinant tissue plasminogen activator and endovascular thrombectomy increase risk of mortality and hemorrhagic conversion, but we suggest to have more clinical studies to evaluate the idea candidates for utilization of intravenous recombinant tissue plasminogen activator and endovascular thrombectomy based on risk: benefit ratio.

Introduction Approximately 5-10% of strokes occur in adults of less than 45 years of age. The rising prevalence of stroke risk factors may increase stroke rates in young adults (YA). We aimed to compare risk factors and outcomes of acute ischemic stroke (AIS) among YA. Methods Adult hospitalizations for AIS and concurrent risk factors were found in the Nationwide Inpatient Sample database. Weighted analysis using chi-square and multivariable survey logistic regression was performed to evaluate AIS-related outcomes and risk factors among YA (18-45 years) and older patients. Results A total of 4,224,924 AIS hospitalizations were identified from 2003 to 2014, out of which 198,378 (4.7%) were YA. Prevalence trend of YA with AIS showed incremental pattern over time (2003: 4.36% to 2014: 4.7%; pTrend<0.0001). In regression analysis, the risk factors associated with AIS in YA were obesity (adjusted odds ratio {aOR}: 2.26; p<0.0001), drug abuse (aOR: 2.56; p<0.0001), history of smoking (aOR: 1.20; p<0.0001), infective endocarditis (aOR: 2.08; p<0.0001), cardiomyopathy (aOR: 2.11; p<0.0001), rheumatic fever (aOR: 4.27; p=0.0014), atrial septal disease (aOR: 2.46; p<0.0001), ventricular septal disease (aOR: 4.99; p<0.0001), HIV infection (aOR: 4.36; p<0.0001), brain tumors (aOR: 7.89; p<0.0001), epilepsy (aOR: 1.43; p<0.0001), end stage renal disease (aOR: 2.19; p<0.0001), systemic lupus erythematous (aOR: 3.76; p<0.0001), polymyositis (aOR: 2.72; p=0.0105), ankylosis spondylosis (aOR: 2.42; p=0.0082), hypercoagulable state (aOR: 4.03; p<0.0001), polyarteritis nodosa (aOR: 5.65; p=0.0004), and fibromuscular dysplasia (aOR: 2.83; p<0.0001). Conclusion There is an increasing trend in AIS prevalence over time among YA. Both traditional and non-traditional risk factors suggest that greater awareness is needed, with prevention strategies for AIS among young adults.
ABSTRACT
BACKGROUND AND PURPOSE: The effect of coronavirus disease 2019 (COVID-19) pandemic on performance of neuroendovascular procedures has not been quantified. METHODS: We performed an audit of performance of neuroendovascular procedures at 18 institutions (seven countries) for two periods; January-April 2019 and 2020, to identify changes in various core procedures. We divided the region where the hospital was located based on the median value of total number of COVID-19 cases per 100,00 population-into high and low prevalent regions. RESULTS: Between 2019 and 2020, there was a reduction in number of cerebral angiograms (30.9% reduction), mechanical thrombectomy (8% reduction), carotid artery stent placement for symptomatic (22.7% reduction) and asymptomatic (43.4% reduction) stenoses, intracranial angioplasty and/or stent placement (45% reduction), and endovascular treatment of unruptured intracranial aneurysms (44.6% reduction) and ruptured (22.9% reduction) and unruptured brain arteriovenous malformations (66.4% reduction). There was an increase in the treatment of ruptured intracranial aneurysms (10% increase) and other neuroendovascular procedures (34.9% increase). There was no relationship between procedural volume change and intuitional location in high or low COVID-19 prevalent regions. The procedural volume reduction was mainly observed in March-April 2020. CONCLUSIONS: We provided an international multicenter view of changes in neuroendovascular practices to better understand the gaps in provision of care and identify individual procedures, which are susceptible to change.

BACKGROUND: The objective of this paper is to assess the clinical outcomes between non-traumatic intracerebral hemorrhage(ICH) in patients using direct oral anticoagulants(DOAC) versus vitamin K antagonists(VKA) for non-valvular atrial fibrillation. We also evaluated the predictors of the poor post-ICH outcomes. METHODS: We have performed pooled meta-analysis to assess long-term clinical outcomes in patients with DOAC-ICH as compared to those with VKA-ICH. A systematic literature search was conducted by searching the full-text English literature in PubMed, EMBASE, and Cochrane databases for observational studies reporting outcomes on interest. MOOSE guidelines were used to collect data till December 31, 2019 and random effects analysis was carried out to account for heterogeneity. For outcomes, risk ratios(RR) and the mean differences were pooled using a random-effects model and weighted mean differences (WMDs), respectively. RESULTS: Seventeen studies met the inclusion criteria (nâ¯=â¯25,354 patients; DOAC-ICH armsâ¯=â¯5,631; VKA-ICH armâ¯=â¯19,273). Patients with DOAC-ICH had smaller hematoma volumes (WMD=-9.59; 95%CI=-15.33--3.85; I2â¯=â¯68.6%) and reduced mortality rate at discharge (RRâ¯=â¯0.82; 95%CIâ¯=â¯0.71-0.96; I2â¯=â¯9.4%). There was no significant difference between the two groups in rate of hematoma expansion (RRâ¯=â¯0.79; 95%CIâ¯=â¯0.56-1.11; I2â¯=â¯50.9%), unfavorable functional outcome(Modified Rankin Scale) at discharge (RRâ¯=â¯0.82; 95%CIâ¯=â¯0.56-1.18; I2â¯=â¯80.2%), unfavorable outcome at 3-months (RRâ¯=â¯0.77; 95%CIâ¯=â¯0.56-1.06; I2â¯=â¯63.9), and mortality at 3-months (RRâ¯=â¯0.90; 95%CIâ¯=â¯0.73-1.10; I2â¯=â¯35â8%). Multivariate meta-regression revealed that the average age of patient population had a significantly negative correlation with(RR=-0.202; pâ¯=â¯0.017) hematoma expansion. CONCLUSION: We conclude that use of DOAC is associated with reduced hematoma volume and mortality rate at discharge. Age is a predictor of the poor outcome of hematoma expansion.

INTRODUCTION: Pneumonia is the most common complication after stroke, but our knowledge on risk factors and predictors of stroke-associated pneumonia (SAP) is limited. We sought to evaluate the predictors and outcomes of SAP among acute ischemic stroke (AIS) hospitalizations. METHODS: This is a cross-sectional study of the Nationwide Inpatient Sample database from the year 2003 to 2014. We identified adult hospitalizations with AIS using International Classification of Diseases, ninth revision, clinical modification (ICD-9-CM) codes. The SAP was identified by the presence of a secondary diagnosis of hospital-acquired pneumonia and ventilator-associated pneumonia. Multivariable survey logistic regression models were utilized to evaluate the predictors of SAP. RESULTS: Overall, 4,224,924 AIS hospitalizations were identified, of which 149,169 (3.53%) had SAP. The prevalence of SAP decreased from 3.72% in 2003 to 3.17% in 2014 (P<0.0001). Mortality [17.12% vs. 4.77%; adjusted odds ratio (aOR): 1.71; P<0.0001] and morbidity (22.53% vs. 3.28%; aOR: 1.86; P<0.0001) were markedly elevated in SAP group compare to non-SAP group. The significant risk factors of pneumonia among AIS hospitalization were nasogastric tube (aOR: 1.21; P=0.0179), noninvasive mechanical ventilation (aOR: 1.65; P<0.0001), invasive mechanical ventilation (aOR: 4.09; P<0.0001), length of stay between 1 to 2 weeks (aOR: 1.99; P<0.0001), >2 weeks (aOR: 3.90; P<0.0001), hemorrhagic conversion (aOR: 1.17; P=0.0002), and epilepsy (aOR: 1.09; P=0.0009). Other concurrent comorbidities which increased the risk of SAP among AIS patients were acquired immune deficiency syndrome (aOR: 1.88; P<0.0001), alcohol abuse (aOR: 1.60; P=0.0006), deficiency anemia (aOR: 1.26; P<0.0001), heart failure (aOR: 1.62; P<0.0001), pulmonary disease (aOR: 1.73; P<0.0001), diabetes (aOR: 1.29; P=0.0288), electrolyte disorders (aOR: 1.50; P<0.0001), paralysis (aOR: 1.22; P<0.0001), pulmonary circulation disorders (aOR: 1.22; P<0.0001), renal failure (aOR: 1.12; P<0.0001), coagulopathy (aOR: 1.13; P=0.0006), and weight loss (aOR: 1.39; P<0.0001). CONCLUSION: Our data underline the considerable epidemiological and prognostic impact of SAP in patients with AIS leading to higher mortality, morbidity, length of stay, and hospital cost despite advancements in care.

Several indexes are used to classify physician burnout, with the Maslach Burnout Inventory currently being the most widely accepted. This index measures physician burnout based on emotional exhaustion, detachment from work, and lack of personal achievement. The overall percentage of physicians with burnout is estimated to be around 40%, but the proportion varies between specialties. Neurology currently has the second-highest rate of burnout and is projected to eventually take the top position. The purpose of this review is to provide a comprehensive overview focusing on the causes and ramifications of burnout and possible strategies for addressing the crisis. Several factors contribute to burnout among neurologist, including psychological trauma associated with patient care and a lack of respect compared to other specialties. Various interventions have been proposed for reducing burnout, and this article explores the feasibility of some of them. Burnout not only impacts the physician but also has adverse effects on the overall quality of patient care and places a strain on the health-care system. Burnout has only recently been recognized and accepted as a health crisis globally, and hence most of the proposed action plans have not been validated. More studies are needed to evaluate the long-term effects of such interventions.
ABSTRACT
BACKGROUND AND PURPOSE: On 11 March 2020, World Health Organization (WHO) declared the COVID-19 infection a pandemic. The risk of ischemic stroke may be higher in patients with COVID-19 infection similar to those with other respiratory tract infections. We present a comprehensive set of practice implications in a single document for clinicians caring for adult patients with acute ischemic stroke with confirmed or suspected COVID-19 infection. METHODS: The practice implications were prepared after review of data to reach the consensus among stroke experts from 18 countries. The writers used systematic literature reviews, reference to previously published stroke guidelines, personal files, and expert opinion to summarize existing evidence, indicate gaps in current knowledge, and when appropriate, formulate practice implications. All members of the writing group had opportunities to comment in writing on the practice implications and approved the final version of this document. RESULTS: This document with consensus is divided into 18 sections. A total of 41 conclusions and practice implications have been developed. The document includes practice implications for evaluation of stroke patients with caution for stroke team members to avoid COVID-19 exposure, during clinical evaluation and performance of imaging and laboratory procedures with special considerations of intravenous thrombolysis and mechanical thrombectomy in stroke patients with suspected or confirmed COVID-19 infection. CONCLUSIONS: These practice implications with consensus based on the currently available evidence aim to guide clinicians caring for adult patients with acute ischemic stroke who are suspected of, or confirmed, with COVID-19 infection. Under certain circumstances, however, only limited evidence is available to support these practice implications, suggesting an urgent need for establishing procedures for the management of stroke patients with suspected or confirmed COVID-19 infection.

In rural and underserved areas, there are restrictions in healthcare due to the lack of availability of neurologists; patients have to travel long distances to receive the required care. Considering the fact that neurological conditions have large mortality and disability rates, there is a need for innovative services like tele-neurology. It is an important tool in improving the health and quality of life by using different ways of communication between neurologists and patients, or neurologists and other providers. We examine the current types of facilities available in tele-neurology, as well as outcomes, barriers, limitations, legal litigations, and the multidisciplinary nature based on prior studies. We have also suggested recommendations for the future of tele-neurology including effective-accessibility and inexpensive-utilization in developing countries. There are various tele-health programs created by The Veterans Health Administration including a clinical video tele-health (CVT) system. This system allows direct patient care of veterans by neurologists. The University of South Carolina implemented a web-based tele-stroke program in which acute ischemic stroke patients were treated in the Emergency Department (ED) of rural hospitals by neurologists, after consulting with rural ED physicians. With growing technology and popularity of tele-neurology, there are now international collaborative efforts in tele-medicine that are looking to be adapted to tele-neurology. Thus, tele-neurology can provide quality neurological care with patient satisfaction, as well as time and cost savings. The tele-stroke group established by TRUST-tPA trial (Therapeutic Trial Evaluating Efficacy of Telemedicine (TELESTROKE) of Patients With Acute Stroke) has 10 community hospital-emergency rooms that were connected to a stroke center. It was found that tele-stroke is appropriate in places where there is no way for a patient to access a stroke unit within a 4.5-hour time window. Like other tele-neurology subtypes, tele-epilepsy and pediatric tele-neurology also offer more follow-up care to people of remote areas which have limited access. There are other subtypes like mental health, chronic neurological care, and hospitalist which are very effective in improving outcome and quality of life of people living in remote areas. Tele-neurology has effectively reduced travel costs and times; there is high patient satisfaction and reduced disparity for general and specialized neurological care. But there are certain limitations like large equipment costs, certain bandwidth requirement, and trained staff to use the equipment. Transmission of patient information using public internet raises the concern of legality. There should be sufficient encryption to satisfy the Health Insurance Portability and Accountability Act (HIPAA) requirements to ensure patient confidentiality and safety of personal data. The adaptation of tele-neurology is a powerful and innovative way to enhance healthcare in areas with a shortage of specialists. Implementation of this tool is limited due to cost burden, lack of expertise to implement necessary technology, legal litigations, and suitable financial and professional incentives for the users. This review focuses on the trajectory of utilization and the issues to be addressed in order to provide the full benefits of tele-neurology to undeserved communities in the future.
ABSTRACT
Ipilimumab (Bristol-Myers Squibb Co., New York, NY) is a novel anticancer medication used for the treatment of metastatic melanoma. The exact mechanism of its action remains unclear; however, data from previous clinical trials postulates the immunomodulatory activity of ipilimumab to enhance therapeutic effectiveness. Ipilimumab was approved by the Food and Drug Administration (FDA) in March 2011 for use in stage III and IV of unresectable metastatic melanoma. We report a single case of acute inflammatory demyelinating polyneuroradiculopthy (AIDP) in the patient treated with ipilimumab for recurrent metastatic melanoma. The patient presented with multiple falls that started after the third infusion of ipilimumab. Other symptoms were hoarseness of voice, motor deficits in his right arms, and tingling in both hands. The deficits progressed into near complete loss of movement and sensation in all four extremities over the course of two weeks. However, his bladder and bowel functions were intact. There was no history of fever, recent travel, exposure to sick contacts, insect bites, or gastrointestinal symptoms. Along with strong immune-mediated pharmacological response towards cancer cells, ipilimumab also induces immune-related adverse events (irAEs) within normal tissues by the mechanism of molecular mimicry.
ABSTRACT
BACKGROUND: Carotid endarterectomy (CEA) is infrequently performed in patients with mild to moderate thrombocytopenia. OBJECTIVE: To determine whether preoperative thrombocytopenia is associated with a higher rate of complications after CEA. METHODS: We analyzed patient characteristics, comorbid conditions, operative details, and 30-day postoperative outcomes for patients who underwent CEA in the CEA-targeted American College of Surgeons National Surgical Quality Improvement Program Registry. Thrombocytopenia was defined based on the preprocedure platelet count of ≤150 â000 platelets/µL. The odds ratios (ORs) for selected outcomes were calculated using logistic regression with stepwise forward selection with age, sex, symptomatic status, and high-risk individuals as potential confounders. RESULTS: Thrombocytopenia was present in 896 of 8658 patients (10.3%) who underwent CEA: mild (100 000-149 000 platelets/µL) and moderate (50 000-99 000 platelets/µL) in 805 patients (89.8%) and 91 patients (10.2%), respectively. The adjusted rates of myocardial infarction/arrhythmia (3.7% vs 1.8%; OR: 1.9; 95% confidence interval [CI]: 1.3-2.8; P = .001), unplanned intubations (2.6% vs 1.2%; OR: 2.2; 95% CI: 1.4-3.5; P = .001), ventilator requirement >48 hours (1.5% vs 0.7%; OR: 2.1; 95% CI: 1.1-3.8; P = .02), deep venous thrombosis/thrombophlebitis (0.7% vs 0.2%; OR: 3.7; 95% CI: 1.4-9.7; P = .01), and surgical deep incisional infections (0.3% vs 0.1%; OR: 4.3; 95% CI: 1.1-17.4; P = .04) post-CEA were higher among patients with thrombocytopenia compared with those without thrombocytopenia. Thrombocytopenia did not significantly contribute to 1-month mortality or stroke. CONCLUSION: The higher rate of postprocedure complications in patients with preoperative thrombocytopenia needs to be recognized for adequate risk stratification before CEA.

Stroke is the leading cause of adult disability and the fifth leading cause of death in the United States. In 2010, the cost of stroke to the health care system in the United States was estimated to be $71.55 billion, and it is projected to double over the next 20 years. Cardioembolism is a leading pathophysiologic cause of stroke. Along with a careful review of the presenting history and clinical symptomatology, early radiographic studies including computed tomography (CT) and MRI, may demonstrate certain characteristics that may be suggestive of a cardioembolic origin to a stroke of concern.
