RESUMO
BACKGROUND AND IMPORTANCE: Chordomas are centrally located, expansile soft tissue neoplasms that arise from the remnants of the embryological notochord. Hemorrhagic presentation is exceedingly rare and can resemble pituitary apoplexy. Moreover, a purely intrasellar location of a chordoma is extremely uncommon. We report a case of a hemorrhagic intrasellar chordoma in an adult male, which presented similarly to pituitary apoplexy and was resolved with surgical resection. CLINICAL PRESENTATION: A 69-year-old male presented with a 4 week history of acute onset headache and concurrent diplopia, with significantly reduced testosterone and slightly reduced cortisol. His left eye demonstrated a sixth cranial nerve palsy. Magnetic resonance imaging of the brain showed a large hemorrhagic mass in the pituitary region with significant compression of the left cavernous sinus and superior displacement of the pituitary gland. The patient underwent an endoscopic endonasal transsphenoidal approach for the resection of the lesion. Near total resection was achieved. Final pathology revealed chordoma with evidence of intratumoral hemorrhage, further confirmed by immunopositive stain for brachyury. Post-operatively, the patient had improved diplopia and was discharged home on low dose hydrocortisone. At 3-month follow-up, his diplopia was resolved and new MRI showed stable small residual disease. CONCLUSIONS: Apoplectic chordomas are uncommon given chordoma's characteristic lack of intralesional vascularity and represent a diagnostic challenge in the sellar region. Our unique case demonstrates that despite our initial impression of pituitary apoplexy, this was ultimately a case of apoplectic chordoma that responded well to endoscopic endonasal surgery.

BACKGROUND: Lacunar strokes (LS) are ischemic strokes of the small perforating arteries of deep gray and white matter of the brain. Frailty has been associated with greater mortality and attenuated response to treatment after stroke. However, the effect of frailty on patients with LS has not been previously described. OBJECTIVE: To analyze the association between frailty and outcomes in LS. METHODS: Patients with LS were selected from the National Inpatient Sample (NIS) 2016-2019 using the International Classification of Disease, 10th edition (ICD-10) diagnosis codes. The 11-point modified frailty scale (mFI-11) was used to group patients into severely frail and non-severely frail cohorts. Demographics, clinical characteristics, and complications were defined. Health care resource utilization (HRU) was evaluated by comparing total hospital charges and length of stay (LOS). Other outcomes studied were discharge disposition and inpatient death. RESULTS: Of 48,980 patients with LS, 10,830 (22.1%) were severely frail. Severely frail patients were more likely to be older, have comorbidities, and pertain to lower socioeconomic status categories. Severely frail patients with LS had worse clinical stroke severity and increased rates of complications such as urinary tract infection (UTI) and pneumonia (PNA). Additionally, severe frailty was associated with unfavorable outcomes and increased HRU. CONCLUSION: Severe frailty in LS patients is associated with higher rates of complications and increased HRU. Risk stratification based on frailty may allow for individualized treatments to help mitigate adverse outcomes in the setting of LS.

BACKGROUND: Previous literature has identified a survival advantage in acute ischemic stroke (AIS) patients with elevated body mass indices (BMIs), a phenomenon termed the "obesity paradox." OBJECTIVE: The aim of this study was to evaluate the independent association between obesity and clinical outcomes following AIS. METHODS: Weighted discharge data from the National Inpatient Sample were queried to identify AIS patients from 2015 to 2018. Multivariable logistic regression and Cox proportional hazards modeling were performed to evaluate associations between obesity (BMI ≥ 30) and clinical endpoints following adjustment for acute stroke severity and comorbidity burden. RESULTS: Among 1,687,805 AIS patients, 216,775 (12.8%) were obese. Compared to nonobese individuals, these patients were younger (64 vs. 72 mean years), had lower baseline NIHSS scores (6.9 vs. 7.9 mean score), and a higher comorbidity burden. Multivariable analysis demonstrated independent associations between obesity and lower likelihood of mortality (adjusted odds ratio [aOR] 0.76, 95% confidence interval [CI]: 0.71, 0.82, p < 0.001; hazard ratio 0.84, 95% CI: 0.73, 0.97, p = 0.015), intracranial hemorrhage (aOR 0.87, 95% CI: 0.82, 0.93, p < 0.001), and routine discharge to home (aOR 0.97, 95% CI: 0.95, 0.99; p = 0.015). Mortality rates between obese and nonobese patients were significantly lower across stroke severity thresholds, but this difference was attenuated among high severity (NIHSS > 20) strokes (21.6% vs. 23.2%, p = 0.358). Further stratification of the cohort into BMI categories demonstrated a "U-shaped" association with mortality (underweight aOR 1.58, 95% CI: 1.39, 1.79; p < 0.001, overweight aOR 0.64, 95% CI: 0.42, 0.99; p = 0.046, obese aOR 0.77, 95% CI: 0.71, 0.83; p < 0.001, severely obese aOR 1.18, 95% CI: 0.74, 1.87; p = 0.485). Sub-cohort assessment of thrombectomy-treated patients demonstrated an independent association of obesity (BMI 30-40) with lower mortality (aOR 0.79, 95% CI: 0.65, 0.96; p = 0.015), but not with routine discharge. CONCLUSION: This cross-sectional analysis demonstrates a lower likelihood of discharge to home as well as in-hospital mortality in obese patients following AIS, suggestive of a protective effect of obesity against mortality but not against all poststroke neurological deficits in the short term which would necessitate placement in acute rehabilitation and long-term care facilities.

OBJECTIVE: Limited evidence exists characterizing the incidence, risk factors, and clinical associations of cerebral vasospasm following traumatic intracranial hemorrhage (tICH) on a large scale. Therefore, the authors sought to use data from a national inpatient registry to investigate these aspects of posttraumatic vasospasm (PTV) to further elucidate potential causes of neurological morbidity and mortality subsequent to the initial insult. METHODS: Weighted discharge data from the National (Nationwide) Inpatient Sample from 2015 to 2018 were queried to identify patients with tICH who underwent diagnostic angiography in the same admission and, subsequently, those who developed angiographically confirmed cerebral vasospasm. Multivariable logistic regression analysis was performed to identify significant associations between clinical covariates and the development of vasospasm, and a tICH vasospasm predictive model (tICH-VPM) was generated based on the effect sizes of these parameters. RESULTS: Among 5880 identified patients with tICH, 375 developed PTV corresponding to an incidence of 6.4%. Multivariable adjusted modeling determined that the following clinical covariates were independently associated with the development of PTV, among others: age (adjusted odds ratio [aOR] 0.98, 95% CI 0.97-0.99; p < 0.001), admission Glasgow Coma Scale score < 9 (aOR 1.80, 95% CI 1.12-2.90; p = 0.015), intraventricular hemorrhage (aOR 6.27, 95% CI 3.49-11.26; p < 0.001), tobacco smoking (aOR 1.36, 95% CI 1.02-1.80; p = 0.035), cocaine use (aOR 3.62, 95% CI 1.97-6.63; p < 0.001), fever (aOR 2.09, 95% CI 1.34-3.27; p = 0.001), and hypokalemia (aOR 1.62, 95% CI 1.26-2.08; p < 0.001). The tICH-VPM achieved moderately high discrimination, with an area under the curve of 0.75 (sensitivity = 0.61 and specificity = 0.81). Development of vasospasm was independently associated with a lower likelihood of routine discharge (aOR 0.60, 95% CI 0.45-0.78; p < 0.001) and an extended hospital length of stay (aOR 3.53, 95% CI 2.78-4.48; p < 0.001), but not with mortality. CONCLUSIONS: This population-based analysis of vasospasm in tICH has identified common clinical risk factors for its development, and has established an independent association between the development of vasospasm and poorer neurological outcomes.

OBJECTIVE: Studies examining the risk factors and clinical outcomes of arterial vasospasm secondary to cerebral arteriovenous malformation (cAVM) rupture are scarce in the literature. The authors used a population-based national registry to investigate this largely unexamined clinical entity. METHODS: Admissions for adult patients with cAVM ruptures were identified in the National Inpatient Sample during the period from 2015 to 2019. Complex samples multivariable logistic regression and chi-square automatic interaction detection (CHAID) decision tree analyses were performed to identify significant associations between clinical covariates and the development of vasospasm, and a cAVM-vasospasm predictive model (cAVM-VPM) was generated based on the effect sizes of these parameters. RESULTS: Among 7215 cAVM patients identified, 935 developed vasospasm, corresponding to an incidence rate of 13.0%; 110 of these patients (11.8%) subsequently progressed to delayed cerebral ischemia (DCI). Multivariable adjusted modeling identified the following baseline clinical covariates: decreasing age by decade (adjusted odds ratio [aOR] 0.87, 95% CI 0.83-0.92; p < 0.001), female sex (aOR 1.68, 95% CI 1.45-1.95; p < 0.001), admission Glasgow Coma Scale score < 9 (aOR 1.34, 95% CI 1.01-1.79; p = 0.045), intraventricular hemorrhage (aOR 1.87, 95% CI 1.17-2.98; p = 0.009), hypertension (aOR 1.77, 95% CI 1.50-2.08; p < 0.001), obesity (aOR 0.68, 95% CI 0.55-0.84; p < 0.001), congestive heart failure (aOR 1.34, 95% CI 1.01-1.78; p = 0.043), tobacco smoking (aOR 1.48, 95% CI 1.23-1.78; p < 0.019), and hospitalization events (leukocytosis [aOR 1.64, 95% CI 1.32-2.04; p < 0.001], hyponatremia [aOR 1.66, 95% CI 1.39-1.98; p < 0.001], and acute hypotension [aOR 1.67, 95% CI 1.31-2.11; p < 0.001]) independently associated with the development of vasospasm. Intraparenchymal and subarachnoid hemorrhage were not associated with the development of vasospasm following multivariable adjustment. Among significant associations, a CHAID decision tree algorithm identified age 50-59 years (parent node), hyponatremia, and leukocytosis as important determinants of vasospasm development. The cAVM-VPM achieved an area under the curve of 0.65 (sensitivity 0.70, specificity 0.53). Progression to DCI, but not vasospasm alone, was independently associated with in-hospital mortality (aOR 2.35, 95% CI 1.29-4.31; p = 0.016) and lower likelihood of routine discharge (aOR 0.62, 95% CI 0.41-0.96; p = 0.031). CONCLUSIONS: This large-scale assessment of vasospasm in cAVM identifies common clinical risk factors and establishes progression to DCI as a predictor of poor neurological outcomes.

OBJECTIVE: The authors sought to analyze a large, publicly available, nationwide hospital database to further elucidate the impact of cardiopulmonary arrest (CA) in association with subarachnoid hemorrhage (SAH) on short-term outcomes of mortality and discharge disposition. METHODS: This retrospective cohort study was conducted by analyzing de-identified data from the National (Nationwide) Inpatient Sample (NIS). The publicly available NIS database represents a 20% stratified sample of all discharges and is powered to estimate 95% of all inpatient care delivered across hospitals in the US. A total of 170,869 patients were identified as having been hospitalized due to nontraumatic SAH from 2008 to 2014. RESULTS: A total of 5415 patients (3.2%) were hospitalized with an admission diagnosis of CA in association with SAH. Independent risk factors for CA included a higher Charlson Comorbidity Index score, hospitalization in a small or nonteaching hospital, and a Medicaid or self-pay payor status. Compared with patients with SAH and not CA, patients with CA-SAH had a higher mean NIS Subarachnoid Severity Score (SSS) ± SD (1.67 ± 0.03 vs 1.13 ± 0.01, p < 0.0001) and a vastly higher mortality rate (82.1% vs 18.4%, p < 0.0001). In a multivariable model, age, NIS-SSS, and CA all remained significant independent predictors of mortality. Approximately 18% of patients with CA-SAH survived and were discharged to a rehabilitation facility or home with health services, outcomes that were most predicted by chronic disease processes and large teaching hospital status. CONCLUSIONS: In the largest study of its kind, CA at onset was found to complicate roughly 3% of spontaneous SAH cases and was associated with extremely high mortality. Despite this, survival can still be expected in approximately 18% of patients.

OBJECTIVES: Despite the success of mechanical thrombectomy in large vessel acute ischemic stroke, recanalization may fail due to difficult anatomic access or peripheral arterial occlusive disease. In these cases, transcarotid access may be used as an alternative, but it has not gained prominence due to safety concerns. Our objective was to assess the efficacy and safety of transcarotid access for mechanical thrombectomy. MATERIALS AND METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to perform a systematic review with articles published from 2010 to 2020 summarizing pre-intervention characteristics, techniques utilized, and outcomes of patients undergoing mechanical thrombectomy via trans-carotid puncture. We performed a meta-analysis of clinical outcomes, reperfusion times and overall complications rates of trans-carotid approach. RESULTS: Six studies describing 80 total attempts at carotid access, 72 of which were successful (90% success rate), were included. Direct carotid puncture was most often used as a rescue technique (87% of patients) secondary to failed femoral access. Successful recanalization was achieved in 76% of patients. 90 day modified Rankin Scale ≤ 2 was achieved in 28% of patients. Carotid puncture-reperfusion time was 32 min (CI = 24-40, p < 0.001). Cervical complications occurred at a rate of 26.5% (95% CI = 17%-38%). Only 1.3% (1/80 patients) had a fatal outcome and 96% of complications required no intervention. CONCLUSIONS: Our results on the safety and efficacy of transcarotid access suggests that this approach is a viable alternative to failed thrombectomy when transfemoral or trans-radial access may be impractical.

BACKGROUND: A 13-year-old female patient was diagnosed with a tectal glioma (TG), a subgroup of astrocytoma that can result in obstructive hydrocephalus secondary to aqueductal stenosis. Endoscopic third ventriculostomy (ETV) is used to treat this type of hydrocephalus with a good success rate. Our institution performs ETV and Ommaya reservoir (OR) placement in these cases. The OR allows measurement of intracranial pressure (ICP) and cerebrospinal fluid (CSF) access and a method for performing ventricular dye studies to evaluate third ventricular stoma (TVS) patency. In this case, a porencephalic cyst (PC) developed around the OR's ventricular catheter (OVC) two and a half months after surgery. CONCLUSION: The PC is thought to have developed in association with TVS stoma closure and resolved after ETV revision.

Central retinal artery occlusion (CRAO) is a rare and visually debilitating vascular condition characterized by sudden and severe vision loss. CRAO is a compelling target for intravenous alteplase (tPA) and endovascular mechanical thrombectomy (MT) due to pathophysiological similarities with acute ischemic stroke; however, the utility of these interventions in CRAO remains dubious due to limited sample sizes and potential risks. To assess usage and outcomes of tPA and MT in CRAO, we queried the National Inpatient Sample database using International Classification of Disease, Ninth and Tenth edition for patients with CRAO and acute ischemic stroke between 2010 and 2019. Our cohort of 5009 CRAO patients were younger with higher rates of obesity, hypertension, long-term anticoagulant use, and tobacco use compared to acute ischemic stroke patients. CRAO patients had lower rates of tPA administration (3.41% vs 6.21%) and endovascular MT (0.38% vs 1.31%) but fewer complications, including deep vein thrombosis, pneumonia, urinary tract infection, acute kidney injury, and acute myocardial infarction (all P < 0.01). CRAO patients had lower rates of poor functional outcome (31.74% vs 58.1%) and in-hospital mortality (1.2% vs 5.64%), but higher rates of profound blindness (9.24% vs 0.58%). A multivariate regression showed no relationship between tPA and MT and profound blindness, although the limited sample size of patients receiving interventions may have contributed to this apparent insignificance. Further investigation of larger patient cohorts and alternative treatment modalities could provide valuable insights for revascularization therapies in CRAO to optimize visual restoration and clinical outcomes.

BACKGROUND: Despite the widespread use of heparin during and following endovascular procedures in the management of aneurysmal subarachnoid hemorrhage (SAH) patients, limited research has explored the incidence and impact of heparin-induced thrombocytopenia (HIT) on SAH. METHODS: Descriptive statistics, multivariate regressions, and propensity score-matching were employed to compare clinical characteristics, comorbidities, interventions, complications, and outcomes of HIT in SAH patients identified within the US National Inpatient Sample database from 2010 to 2019. RESULTS: Among 76 387 SAH patients from 2010 to 2019, 166 (0.22%) developed HIT. HIT was identified as a significant predictor of prolonged length of stay (OR 6.799, 95% CI 3.985 to 11.6, P<0.01) and poor functional outcomes (OR 2.541, 95% CI 1.628 to 3.966, P<0.01) after adjusting for relevant factors. HIT incidence was higher in patients with elevated SAH severity scores (1.42 vs 1.06, P<0.01), younger patients (58.04 vs 61.39 years, P=0.01), overweight individuals (0.4% vs 0.2%, P<0.01), those on long-term anticoagulants (10.84% vs 5.72%, P<0.01), or with a cerebrospinal fluid drainage device (external ventricular drain, ventriculoperitoneal shunt; P<0.01). HIT patients showed increased rates of endovascular coiling, ventricular drain placement, shunt placement, deep vein thrombosis, urinary tract infection, acute kidney injury, pulmonary embolism, venous sinus thrombosis, pneumonia, and cerebral vasospasm (all P<0.01). CONCLUSION: SAH patients with HIT exhibited various comorbidities and increased rates of complications, which may contribute to extended hospital stays. This nationwide study aids clinical suspicion and highlights HIT's impact on SAH patients.

Acute ischemic stroke is a leading cause of morbidity and mortality in the United States. Treatment goals remain focused on restoring blood flow to compromised areas. However, a major concern arises after reperfusion occurs. Cerebral ischemic reperfusion injury is defined as damage to otherwise salvageable brain tissue occurring with the reestablishment of the vascular supply to that region. The pool of eligible patients for revascularization continues to grow, especially with the recently expanded endovascular therapeutic window. Neurointensivists should understand and manage complications of successful recanalization. In this review, we examine the pathophysiology, diagnosis, and potential management strategies in cerebral ischemic reperfusion injury.
RESUMO
Sinus pericranii (SP) are abnormal vascular connections between extracranial scalp venous channels and intracranial dural sinuses. This vascular abnormality rarely results in significant sequelae, but in select cases, it can be symptomatic. We describe the case of a 7-year-old girl with an SP who experienced intermittent visual, motor, and sensory symptoms not previously described in the literature. Her symptoms resolved after surgical treatment of the SP. We propose a mechanism for her symptoms and the rationale for the role of neurosurgical intervention along with a review of the literature.

Frailty is an emerging concept in clinical practice used to predict outcomes and dictate treatment algorithms. Frail patients, especially older adults, are at higher risk for adverse outcomes. Aneurysmal subarachnoid hemorrhage (aSAH) is a neurosurgical emergency associated with high morbidity and mortality rates that have previously been shown to correlate with frailty. However, the relationship between treatment selection and post-treatment outcomes in frail aSAH patients is not established. We conducted a meta-analysis of the relevant literature in accordance with PRISMA guidelines. We searched PubMed, Embase, Web of Science, and Google Scholar using "Subarachnoid hemorrhage AND frailty" and "subarachnoid hemorrhage AND frail" as search terms. Data on cohort age, frailty measurements, clinical grading systems, and post-treatment outcomes were extracted. Of 74 studies identified, four studies were included, with a total of 64,668 patients. Percent frailty was 30.4% under a random-effects model in all aSAH patients (p < 0.001). Overall mortality rate of aSAH patients was 11.7% when using a random-effects model (p < 0.001). There was no significant difference in mortality rate between frail and non-frail aSAH patients, but this analysis only included two studies and should be interpreted cautiously. Age and clinical grading, rather than frailty, independently predicted outcomes and mortality in aSAH patients.
RESUMO
BACKGROUND: Intracerebral hemorrhage (ICH) carries significant morbidity and mortality. Previous single-center retrospective analysis suggests that end-stage renal disease (ESRD) is a risk factor for severe ICH and worse outcomes. This investigation aims to examine the impact of ESRD on ICH severity, complications, and outcomes using a multicenter national database. METHODS: The International Classification of Disease, Ninth and Tenth Revision Clinical Modification codes were used to query the National Inpatient Sample for patients with ICH and ESRD between 2010 and 2019. Primary endpoints were the functional outcome, length of stay (LOS), and in-hospital mortality. Multivariate variable regression models and a propensity-score matched analysis were established to analyze patient outcomes associated with baseline patient characteristics. RESULTS: We identified 211,266 patients with ICH, and among them, 7,864 (3.77%) patients had a concurrent diagnosis of ESRD. Patients with ESRD were younger (60.85 vs. 67.64, P < 0.01) and demonstrated increased ICH severity (0.78 vs. 0.77, P < 0.01). ESRD patients experienced higher rates of sepsis (15.9% vs. 6.15%, P < 0.01), acute myocardial infarction (8.05% vs. 3.65%, P < 0.01), and cardiac arrest (5.94% vs. 2.4%, P < 0.01). In addition, ESRD predicted poor discharge disposition (odds ratio [OR]: 2.385, 95% confidence interval [CI]: 2.227-2.555, P < 0.01), longer hospital LOS (OR: 1.629, 95% CI: 1.553-1.709, P < 0.01), and in-hospital mortality (OR: 2.786, 95% CI: 2.647-2.932, P < 0.01). CONCLUSIONS: This study utilizes a multicenter database to analyze the effect of ESRD on ICH outcomes. ESRD is a significant predictor of poor functional outcomes, in-hospital mortality, and prolonged stay in the ICH population.
RESUMO
INTRODUCTION: Acute respiratory distress syndrome (ARDS) is a known predictor of poor outcomes in critically ill patients. We sought to examine the role ARDS plays in outcomes in subarachnoid hemorrhage (SAH) patients. Prior studies investigating the incidence of ARDS in SAH patients did not control for SAH severity. Hence, we sought to determine the incidence ARDS in patients diagnosed with aneurysmal SAH and investigate the predisposing risk factors and impact upon outcomes. METHODS: A retrospective cohort study was conducted using the National Inpatient Sample (NIS) database for the years 2008 to 2014. Multivariate stepwise regression analysis was performed to identify the risk factors and outcome associated with developing ARDS in the setting of SAH. RESULTS: We identified 170,869 patients with non-traumatic subarachnoid hemorrhage, of whom 6962 were diagnosed with ARDS and of those 4829 required mechanical ventilation. ARDS more frequently developed in high grade SAH patients (1.97 ± 0.05 vs. 1.15 ± 0.01; p < 0.0001). Neurologic predictors of ARDS included cerebral edema (OR 1.892, CI 1.180-3.034, p = 0.0035) and medical predictors included cardiac arrest (OR 4.642, CI 2.273-9.482, p < 0.0001) and cardiogenic shock (OR 2.984, CI 1.157-7.696, p = 0.0239). ARDS was associated with significantly worse outcomes (15.5% vs. 52.9% discharged home, 63.0% vs. 40.8% discharged to rehabilitation facility and 21.5% vs. 6.3% in-hospital mortality). CONCLUSION: Patients with SAH who developed ARDS were less likely to be discharged home, more likely to need rehabilitation and had a significantly higher risk of mortality. The identification of risk factors contributing to ARDS is helpful for improving outcomes and resource utilization.

OBJECTIVE: Patients with developmental disabilities (DD) are frequently excluded from acute ischemic stroke (AIS) randomized control trials. We sought to evaluate the impact of having DD on this patient cohort. METHODS: The National Inpatient Sample was analyzed to explore the impact of AIS and treatment on discharge dispositions in patients with DD. Clinical characteristics, treatments, and outcomes were compared to fully-abled patients with AIS. RESULTS: 1,605,723 patients with AIS were identified from 2010-2019, of whom 4094 (0.30%) had a DD. AIS patients with DD were younger (60.31 vs 70.93 years, p < 0.01), less likely to be Caucasian (66.37%vs 68.09%, p = 0.01), and had higher AIS severity (0.63 vs 0.58, p < 0.01). Tissue plasminogen activator (tPA) was administered in 99,739 (6.2%) fully-abled patients and 196 (4.79%) of patients with DD (p < 0.01). Endovascular thrombectomy (EVT) was performed in 21,066 (1.31%) of fully-abled patients and 35 (0.85%) of patients with DD (p < 0.01). The presence of developmental disabilities were predictive of lower rates of tPA (OR:0.71,CI:0.56-0.87,p < 0.01) and EVT (OR:0.24,CI:0.16-0.36,p < 0.01). In a propensity score-matched cohort of all AIS patients who underwent EVT, there was no difference in functional outcome (p = 0.41), in-hospital mortality (0.10), and LOS (p = 0.79). CONCLUSION: AIS patients with DD were less likely to receive tPA and EVT compared to fully-abled patients. Individuals with DD had higher mortality and worse discharge disposition. There was no significant difference in post-EVT outcomes between fully-abled patients and patients with developmental disabilities. In the absence of prospective clinical trials, population based cross-sectional analyses such as the present study provide valuable clinical insight.

BACKGROUND: Heparin induced thrombocytopenia Type II (HIT-II) is a dangerous thromboembolic complication of heparin therapy. The current literature on incidence and outcomes of HIT-II in aneurysmal subarachnoid hemorrhage (aSAH) patients remains sparse. OBJECTIVE: We report our institution's incidence and outcomes of HIT-II in aSAH patients. METHODS: We performed a retrospective cohort study at an academic medical center between June 2014 and July 2018. All patients had aSAH confirmed by digital subtraction angiography. Diagnosis of HIT-II was determined by positive results on both heparin PF4-platelet antibody ELISA (anti-PF4) and serotonin release assay (SRA). RESULTS: 204 patients met inclusion criteria. Seven patients (7/204, 3.5%) underwent laboratory testing, three of whom met clinical criteria. HIT-II incidence was confirmed in two of these seven patients (2/204, 0.98%), who had high BMI and T4 scores. CONCLUSION: Our institution's report of HIT-II incidence in aSAH patients is lower than previously reported in this population and more closely parallels HIT-II incidence in the general and surgical ICU setting. Widely-accepted American College of Chest Physicians (ACCP) clinical diagnostic criteria in conjunction with anti-PF4 and SRA testing is the gold standard of clinical diagnosis of HIT-II in aSAH patients.

Catheter-based angiography is an essential procedure for the diagnosis and treatment of vascular complications in patients. Since cerebral and coronary angiography are similar techniques that utilize the same access sites and general principles, the associated risks overlap and should be identified to help direct patient care. The purpose of this study was to determine complication rates in a combined cohort of cerebral and coronary angiography patients, as well as conduct a comparative analysis of coronary and cerebral angiography complications. The National Inpatient Sample was queried from 2008 to 2014 to identify patients who underwent coronary or cerebral angiography. After assessment of baseline characteristics, complication rates, and disposition in the combined cohort, propensity matching was utilized to create sub-cohorts of coronary and cerebral angiography patients based on demographics and comorbidities. Comparative analysis of procedural complications and disposition was then performed. A total of 3,763,651 hospitalizations were included in our study cohort (3,505,715 coronary angiographies and 257,936 cerebral angiographies). The median age was 62.9 years, with females being 46.42%. The most prevalent comorbidities in the overall cohort were hypertension (69.92%), coronary artery disease (69.48%), smoking (35.64%), and diabetes mellitus (35.13%). Propensity matching demonstrated that the cerebral angiography cohort had lower rates of acute and unspecified renal failure (5.4% vs 9.2%, OR 0.57, 95% CI, 0.53-0.61, P < 0.001), hemorrhage/hematoma formation (0.8% vs 1.3%, OR 0.63, 95% CI, 0.54-0.73, P < 0.001), and equivalent rates of retroperitoneum hematoma formation (0.03% vs 0.04%, OR 1.49, 95% CI, 0.76-2.90, P = 0.247) and arterial embolism/ thrombus formation (0.3% vs 0.3%, OR 1.01, 95% CI, 0.81-1.27, P = 0.900). Our study showed both cerebral and coronary angiography have generally low rates of procedural complications. Matched cohort analysis demonstrated that cerebral angiography patients are at no greater risk for complications than coronary angiography patients.
RESUMO
Infective Endocarditis (IE) patients are known to have a variety of complications with one of the rarest, but serious being cerebral mycotic aneurysm, which can result in subarachnoid hemorrhage (SAH). Using the National In-Patient Sample database, we sought to determine the rate of acute ischemic stroke (AIS) and outcomes in IE- patients with and without SAH. In total, we identified 82,844 IE-patients from 2010 to 2016, of which 641 had a concurrent diagnosis of SAH. IE patients with SAH had a more complicated course, higher mortality rate (OR 4.65 CI 95% 3.9-5.5, P < 0.001), and worse outcomes. This patient population also had a significantly higher rate of AIS (OR 6.3 CI 95% 5.4-7.4, P < 0.001). Overall, 41.5% of IE-patients with SAH had AIS during their hospitalization as compared to 10.1% of IE only patients. IE-patients with SAH were more likely to undergo endovascular treatment (3.6%) with 0.8% of the IE patients with AIS undergoing mechanical thrombectomy. While IE-patients are at risk for various complications, our study suggests a significant increase in the mortality and risk of AIS in those with SAH.
