RESUMO
This systematic review was performed to understand better the myriad presentations, various therapeutic options, response to therapy, and its clinical outcomes in hyperphosphatemic tumoral calcinosis (HTC). Full texts were selected according to strict inclusion criteria. All case reports of HTC wherein baseline phosphate was measured, treatment offered was mentioned, and information on follow-up and response to therapy that were available were included. A total of 43 of 188 eligible studies (N = 63 patients) met the inclusion criteria. A list of desired data was extracted and graded for methodological quality. A total of 63 individuals (Males = 33) were included from the 43 eligible case studies. The median age of the patients was 18 (IQR 8-32) years. The most frequently involved sites were the hip/gluteal region (34/63; 53.9%) followed by the elbow/forearm (26/63; 41.2%), and the shoulder (18/63; 28.5%). Three patients had conjunctival calcific deposits. The mean (SD) phosphate was 6.9 (1.1) mg/dL. Among the subjects, 36/63 (57.1%) underwent surgical excision with some form of medical therapy. Two patients underwent only surgical excision (2.1%). One patient was maintained on follow-up (1.6%) and 24/63 (38.1%) patients were treated with medical measures. The median (IQR) follow-up duration was 3 (1-9) years. Regression or reduction in lesion size was reported in 19/63 (30.2%) subjects; 20/63 (31.7%) showed progression, 24/63 (38.1%) had features of stable disease, and mortality was reported in 3 patients (4.7%). We report for the first time a detailed description of the clinical and therapeutic response of HTC. A combination of medical measures aimed at lowering serum phosphate appears to be the cornerstone of treatment, although clinical responses may vary.
RESUMO
BACKGROUND: While endovascular thrombectomy (EVT) is beneficial for patients with acute large vessel occlusion ischemic strokes, a significant portion of patients still do poorly despite successful recanalization. Identifying patients at high risk for poor outcomes can be helpful for future clinical trial design and optimizing acute stroke triage. METHODS: Consecutive EVT patients were identified from 2016 to 2021 at a Comprehensive Stroke Center, and clinical information was recorded. Poor outcome was defined as a 90-day modified Rankin Scale (mRS) of 4 or greater despite achieving a modified thrombolysis in cerebral infarction (mTICI) score of 2b or greater. Multivariable regression analyses were used to identify risk factors for poor outcomes, and a scoring system was constructed. RESULTS: 483 patients with successful recanalization were identified. From a randomly selected training cohort (n = 357), the 10-point BAND score was constructed from independent risk factors for poor outcomes: baseline disability (1 point: baseline mRS ≥ 2), age (1 point: 60-69 years, 2 points: 70-79 years, 3 points: 80-84 years, 4 points: 85 years or older), NIHSS (2 points: 13-17, 3 points: 18-22, and 4 points: ≥ 23), and delay from last known normal (1 point: ≥ 6 h). The BAND score was significantly associated with rates of poor outcomes (p < 0.001), and it achieved an area under the receiver-operating characteristic curve (AUC) of 0.80 (95 %CI 0.76-0.85) in our training cohort and 0.78 (95 %CI 0.70-0.86) in our validation cohort (n = 126). Overall, the BAND score had a significantly higher AUC value than the widely validated THRIVE score and the THRIVE-EVT calculation (p = 0.001 and 0.029, respectively). Among patients with high BAND scores (7 or higher), 88.2 % had poor outcomes. CONCLUSION: The BAND score is a simple tool to predict poor outcomes despite successful recanalization. Future studies are needed to confirm the BAND score's external validity.

Intraventricular hemorrhage (IVH) is a clinical challenge observed among 40-45% of intracerebral hemorrhage (ICH) cases. IVH can be classified according to the source of the hemorrhage into primary and secondary IVH. Primary intraventricular hemorrhage (PIVH), unlike secondary IVH, involves only the ventricles with no hemorrhagic parenchymal source. Several risk factors of PIVH were reported which include hypertension, smoking, age, and excessive alcohol consumption. IVH is associated with high mortality and morbidity and several prognostic factors were identified such as IVH volume, number of ventricles with blood, involvement of fourth ventricle, baseline Glasgow Coma Scale score, and hydrocephalus. Prompt management of patients with IVH is required to stabilize the clinical status of patients upon admission. Nevertheless, further advanced management is crucial to reduce the morbidity and mortality associated with intraventricular bleeding. Recent treatments showed promising outcomes in the management of IVH patients such as intraventricular anti-inflammatory drugs, lumbar drainage, and endoscopic evacuation of IVH, however, their safety and efficacy are still in question. This literature review presents the epidemiology, physiopathology, risk factors, and outcomes of IVH in adults with an emphasis on recent treatment options.
RESUMO
The video highlights a challenging case of bilateral vertebral artery dissection presenting with subarachnoid hemorrhage. The patient was found to have a critical flow-limiting stenosis in his dominant right vertebral artery and a ruptured pseudoaneurysm in his left vertebral artery. A single-stage endovascular treatment with stent reconstruction of the right vertebral artery and coil embolization sacrifice of the left side was performed. The case highlights the rationale for treatment and potential alternative strategies.The video can be found here: https://youtu.be/e0U_JE2jISw.

PURPOSE: Computerized tomography urogram is recommended when investigating patients with hematuria. We determined the incidence of urinary tract cancer and compared the diagnostic accuracy of computerized tomography urogram to that of renal and bladder ultrasound for identifying urinary tract cancer. MATERIALS AND METHODS: The DETECT (Detecting Bladder Cancer Using the UroMark Test) I study is a prospective observational study recruiting patients 18 years old or older following presentation with macroscopic or microscopic hematuria at a total of 40 hospitals. All patients underwent cystoscopy and upper tract imaging comprising computerized tomography urogram and/or renal and bladder ultrasound. RESULTS: A total of 3,556 patients with a median age of 68 years were recruited in this study, of whom 2,166 underwent renal and bladder ultrasound, and 1,692 underwent computerized tomography urogram in addition to cystoscopy. The incidence of bladder, renal and upper tract urothelial cancer was 11.0%, 1.4% and 0.8%, respectively, in macroscopic hematuria cases. Patients with microscopic hematuria had a 2.7%, 0.4% and 0% incidence of bladder, renal and upper tract urothelial cancer, respectively. The sensitivity and negative predictive value of renal and bladder ultrasound to detect renal cancer were 85.7% and 99.9% but they were 14.3% and 99.7%, respectively, to detect upper tract urothelial cancer. Renal and bladder ultrasound was poor at identifying renal calculi. Renal and bladder ultrasound sensitivity was lower than that of computerized tomography urogram to detect bladder cancer (each less than 85%). Cystoscopy had 98.3% specificity and 83.9% positive predictive value. CONCLUSIONS: Computerized tomography urogram can be safely replaced by renal and bladder ultrasound in patients who have microscopic hematuria. The incidence of upper tract urothelial cancer is 0.8% in patients with macroscopic hematuria and computerized tomography urogram is recommended. Patients with suspected renal calculi require noncontrast renal tract computerized tomography. Imaging cannot replace cystoscopy to diagnose bladder cancer.

OBJECTIVE The Pipeline embolization device (PED) is frequently used in the treatment of anterior circulation aneurysms, especially around the carotid siphon, with generally excellent results. However, the PED has its own unique technical challenges, including the occurrence of device foreshortening or migration leading to prolapse into the aneurysm. The authors sought to determine the incidence of this phenomenon, the rescue strategies, and outcomes. METHODS Four institutional databases of neuroendovascular procedures were reviewed for cases of intracranial aneurysms treated with PEDs. Patient and aneurysm data as well as angiographic imaging were reviewed for all cases involving device prolapse into the aneurysm. RESULTS A total of 413 intracranial aneurysms were treated with PEDs during the study period, by 5 neurointerventionalists. Large and giant aneurysms (≥ 2 cm) accounted for 32 of these aneurysms. Among these 32 PEDs, prolapse into the aneurysm occurred in 3 patients, with 1 of these PEDs successfully rescued and the other 2 left in situ. No patients suffered any severe complications. The 2 patients in whom the PEDs were left in situ remained on antiplatelet therapy. CONCLUSIONS The PED may foreshorten or migrate during or after deployment, leading to prolapse into the aneurysm. This phenomenon appears to be associated with large and giant aneurysms, vessel tortuosity, short landing zones, and use of balloon angioplasty. Future study and follow-up is needed to further evaluate this phenomenon, but some of the observations and techniques described in this paper may help to prevent or salvage prolapsed devices.

PURPOSE: Although the incidence of myelomeningocele (MMC) has declined over the past decades with folic acid supplementation and prenatal screening, neural tube defects remain the most common birth defect in the USA. A majority of affected neonates require surgical repair. To characterize US trends in the epidemiology and hospital utilization of MMC repair over the past decade, we analyzed a nationally representative database. METHODS: We queried the Healthcare Cost and Utilization Project (HCUP) Kid's Inpatient Database (KID) for all discharges with procedure code for MMC repair for the years 2000, 2003, 2006, and 2009. The cohorts from these time points were compared for their demographic and in-hospital variables. Results are reported as estimated frequencies and means with 95 % confidence intervals (CI). RESULTS: Sex, race, insurance status, family income level, and mortality of affected infants have not changed significantly over the decade. A majority of neonatal MMC repairs occur in larger hospital bed size and more specialized children's hospital centers. Of patients, 52.3 to 60 % receive VPS placement during the same admission as the primary MMC repair. Total hospital costs for the MMC hospitalizations have remained relatively stable from 42,843 dollars in 2003 to 46,749 dollars in 2009 (adjusted to 2009 dollars). CONCLUSION: Demographics of children having MMC repair have not changed significantly over the past decade, while these surgeries have become more concentrated in pediatric-specialized centers. There appears to be a plateau in public health and access advances with relatively stable cost of MMC hospital care.

PURPOSE: Vertebral hemangiomas are common benign vascular tumors of the spine. It is very rare for these lesions to symptomatically compress neural elements. If spinal cord compression does occur, it usually involves only a single level. Multilevel vertebral hemangiomas causing symptomatic spinal cord compression have never been reported in the pediatric population to the best of our knowledge. METHODS: We report the case of a 15-year-old boy presenting with progressive paraparesis due to thoracic spinal cord compression from a multilevel thoracic hemangioma (T5-T10) with epidural extension. RESULTS: Because of his progressive neurological deficit, he was initially treated with urgent multilevel decompressive laminectomies from T4 to T11. This was to be followed by radiotherapy for residual tumor, but the patient was unfortunately lost to follow-up. He re-presented 3 years later with recurrent paraparesis and progressive disease. This was treated with urgent radiotherapy with good response. As of 6 months follow-up, he has made an excellent neurological recovery. CONCLUSIONS: In this report, we present the first case of a child with multilevel vertebral hemangiomas causing symptomatic spinal cord compression and review the literature to detail the pathophysiology, management, and treatment of other cases of spinal cord compression by vertebral hemangiomas.

This report outlines the innovative use of augmented reality (AR) in the surgical planning and treatment of a spinal dural arteriovenous fistula (dAVF) via a minimally invasive technique. AR technology by way of an Apple Vision Pro headset was employed to enhance preoperative visualization and understanding of the pathology, leading to successful surgical ligation of the AVF. This case describes a 56-year-old male presenting with progressive weakness and thoracic myelopathy who showed marked improvement postoperatively, highlighting AR's potential to improve surgical approach and outcomes.
RESUMO
Spinal cord ischemia remains a persistent challenge after endovascular aortic aneurysm repair. We present a novel direct aorta to segmental artery bypass before aneurysm repair in a 64-year-old woman presenting with an enlarging aneurysm following dissection. Through an eighth intercostal incision, a polyester graft was sewn into the aorta using pledgeted sutures. An entry needle was used to directly access the previously treated aortic segment, and the opening was stented and angioplasty was performed to create inflow. Anastomoses were performed to a prominent left T10 segmental artery with a harvested saphenous vein. The patient remained neurologically intact postoperatively and the 1-month follow-up angiography demonstrated bypass patency.
RESUMO
BACKGROUND: Large vessel recanalization (LVR) before endovascular therapy (EVT) for acute large vessel ischemic strokes is a poorly understood phenomenon. Better understanding of predictors for LVR is important for optimizing stroke triage and patient selection for bridging thrombolysis. METHODS: In this retrospective cohort study, consecutive patients presenting to a comprehensive stroke center for EVT treatment were identified from 2018 to 2022. Demographic information, clinical characteristics, intravenous thrombolysis (IVT) use, and LVR before EVT were recorded. Factors independently associated with different rates of LVR were identified, and a prediction model for LVR was constructed. RESULTS: 640 patients were identified. 57 (8.9%) patients had LVR before EVT. A minority (36.4%) of LVR patients had significant improvements in National Institutes of Health Stroke Scale. Independent predictors for LVR were identified and used to construct the 8-point HALT score: hyperlipidemia (1 point), atrial fibrillation (1 point), location of vascular occlusion (internal carotid: 0 points, M1: 1 point, M2: 2 points, vertebral/basilar: 3 points), and thrombolysis at least 1.5 hours before angiography (3 points). The HALT score had an area under the receiver-operating curve (AUC) of 0.85 (95% CI 0.81 to 0.90, P<0.001) for predicting LVR. LVR before EVT occurred in only 1 of 302 patients (0.3%) with low (0-2) HALT scores. CONCLUSIONS: IVT at least 1.5 hours before angiography, site of vascular occlusion, atrial fibrillation, and hyperlipidemia are independent predictors for LVR. The 8-point HALT score proposed in this study may be a valuable tool for predicting LVR before EVT.

With its recent release, the Apple Vision Pro (Apple Inc., Cupertino, CA) represents a promising technological advancement of mixed reality in the field of neurosurgery and medicine more broadly. With all new technologies, it is critical to facilitate early use and assessment of the technology to facilitate adoption by the larger medical community. A 44-year-old female with a history of ruptured intracranial aneurysm status post anterior communicating artery aneurysm clipping presented with worsened confusion and intermittent headache. CT imaging revealed evidence of hydrocephalus due to the malfunction of a previous right parietal ventriculoperitoneal (VP) shunt. Prior to the case, the Apple Vision Pro was used in the operating room to visualize and interact with a 3D model of the patient's anatomy for the patient undergoing a VP shunt placement. A visualization of the 3D model through the headset was used to plan the approach and entry point. At the conclusion of the procedure, all clinicians and operating staff who used the technology for planning completed a survey about their initial impressions of the headset. Overall, users felt the 3D models felt realistic (4.5/5), that the display of the user's real-world view felt natural (4.3/5), and that the headset did not cause eye strain or fatigue (4.5/5). The majority of users responded that they would continue to use the headset for cases (4/5). This represents one of the first known clinical uses of the Apple Vision Pro. It is a cutting-edge technology that will likely provide immense value for healthcare providers as it becomes more integrated into clinical care.
RESUMO
BACKGROUND: The optimal recanalization goal and number of endovascular thrombectomy (EVT) passes for elderly patients with large vessel occlusion strokes is unclear. METHODS: Consecutive patients 80 years or older undergoing EVT were identified from 2016 to 2022 at a single center. Clinical information, procedural details, and modified treatment in cerebral ischemia (mTICI) scores were collected. Primary outcome was modified Rankin scale (mRS) at 90 days. Bivariate and multivariable analyses were conducted to assess associations between mTICI scores, EVT passes, and 90-day outcomes. RESULTS: One hundred twenty-six patients were identified. At 90 days, mTICI 2b recanalization resulted in high rates of poor outcomes (8.7% functional independence and 60.9% mortality) not significantly different from mTICI 0, 1 or 2a (median mRS 6 vs. 6, P = 0.61). Complete recanalization (mTICI 2c or 3) led to significantly better mRS outcomes at 90 days compared to mTICI 2b (median mRS 4 vs. 6, adjusted P = 0.038), with 26.8% functional independence and 37.8% mortality. In multivariable analysis, complete recanalization was significantly associated with better 90-day outcomes than mTICI 2b or lower recanalization (odds ratio 4.24 [95% Confidence interval 1.46-12.3]; P = 0.002), while the number of passes was not independently associated with worse outcomes (P = 0.98). CONCLUSIONS: For octogenarians, mTICI 2b recanalization yields limited clinical benefit and results in poor 90-day outcomes. In contrast, complete recanalization is independently associated with significantly better outcomes. Thus, once the decision is made to pursue EVT in the elderly, mTICI 2c or better recanalization should be the angiographic goal. Providers should not withhold thrombectomy passes based on age alone.

BACKGROUND: Choroid plexus tumors are rare neoplasms that primarily occur in children. The use of the SEER (Surveillance, Epidemiology and End Results) database allows for the analysis of the relationship between prognostic factors and survival. METHODS: We analyzed the SEER database to select pediatric patients (<18 years old) with histologically confirmed diagnoses of choroid plexus papillomas (CPP; WHO Grade 0), atypical CPP (WHO Grade I) and choroid plexus carcinomas (CPC; WHO grade III). In univariate and multivariate analysis, we analyzed the relationship between demographic (age, gender, race, date of diagnosis) and treatment factors (extent of surgical resection, use of adjuvant radiation) on survival. RESULTS: Overall, 168 pediatric subjects with choroid plexus tumors were identified as follows: 75 cases of CPP, 12 cases of atypical CPP and 81 cases of CPC. The median follow-up time was 3.5 years for CPP and 7.7 years for CPC. The median age at diagnosis was 4 years for CPP (10-90th percentile 0-16 years) and 1 year for CPC (10-90th percentile 0-10 years). In univariate regression analysis, CPC histology (ß = -3.2, 95% confidence interval, CI -4.8 to -1.5, p < 0.001) was significantly associated with younger age at diagnosis in comparison to CPP. The mean tumor size was 3.7 cm for CPP and 6.0 cm for CPC (p < 0.001). A higher-grade tumor was associated with significantly increased mortality (hazard ratio, HR = 28.90, 95% CI 3.94-211.83, p = 0.001). Overall survival at 5 years was 98.7% for CPP and 58.5% for CPC (p < 0.001). Among those patients with CPC, gross total resection (GTR) was associated with a significantly lower mortality (HR = 0.21, 95% CI 0.07-0.66, p = 0.007). Overall survival at 5 years was 70.9% after GTR, significantly better than 35.9% after subtotal resection (p = 0.012) and 30% after no surgery (p = 0.003). Radiation treatment was not found to confer a survival benefit in CPC. No demographic characteristics (age, sex, race, date of diagnosis) were significantly associated with mortality. CONCLUSIONS: Analysis of a pediatric cohort of choroid plexus tumors in children in the SEER database shows that tumor grade is predictive of survival. In cases of CPC, the extent of surgical resection, especially GTR, is significantly associated with increased survival. Radiation did not confer survival benefit.

Purpose: The issue of burnout has been identified as one of the most pressing challenges in organizational management, impacting the ability of an organization to succeed as well as employee productivity. In the healthcare industry, burnout is particularly prevalent. Burnout has received increasing attention from scholars, and different models have also been proposed to address this issue. However, burnout is on the rise in healthcare, especially in developing countries, indicating the need for more research on how to mitigate burnout. Research indicates that internal corporate social responsibility (ICSR) has a significant impact on employee behavior. However, little attention has been paid to exploring how ICSR might effectively reduce healthcare burnout. This study aims to investigate how ICSR and employee burnout are related in the healthcare sector of a developing country. In addition, we tested how subjective well-being and resilience mediate and moderate the effect of ICSR on employee burnout. Methods: Data were collected from 402 healthcare employees working in different hospitals in Pakistan. In our study, we used a self-administered questionnaire as a data collection instrument. We have adapted the items in this survey from reliable and already published sources. Data collection was carried out in three waves. Results: Hypotheses were evaluated using structural equation modeling (SEM). Software such as IBM-SPSS and AMOS were used for this purpose. ICSR significantly reduces healthcare employees' burnout, according to the results of the structural analysis. The relationship between ICSR and burnout was also found to be mediated by subjective well-being, and resilience moderated the relationship between ICSR and subjective well-being. Findings: In light of our findings, hospitals can take some important steps to resolve the problem of burnout. The study specifically stresses the importance of ICSR as a contextual organizational resource for preventing burnout among healthcare employees.
RESUMO
The purpose of the study is to test the role of green bond financing on energy efficiency investment and economic growth. To achieve the study objective, fuzzy decision-making modeling technique is applied. The results revealed that bank loans are now the main source of financing for energy efficiency projects. Project-based financing might be replaced with Energy Performance Contracts (EPC) warranting energy efficiency investment. Moreover, green banks invest both public and private funds in energy efficiency promoting economic growth. The usage of green bonds for financing environmentally beneficial projects or companies is limitless. Providing for screening energy efficiency investment proposals with small payback hurdle rates might have large opportunity costs. Green bonds can be used to remove the financing barriers for green finance and sustainability tool. On this, study provides policy implications to key stakeholders; if suggested policy suggestions implemented successfully, these would help to enhance scope of green bond financing to uplift energy efficiency financing and green growth successfully.

OBJECTIVE: The ULTRA Registry is a national multicenter prospective study designed to assess aneurysm occlusion rates and safety profiles of the Target Ultra and Nano coils in the treatment of small intracranial aneurysms (IAs). METHODS: Patients with small (≤ 5 mm) ruptured and unruptured IAs were treated exclusively with Target Ultra and Nano coils. The primary endpoints were the initial rate of complete or near-complete aneurysm occlusion, aneurysm recurrence, and need for retreatment. Secondary endpoints were device- and procedure-related adverse events, hemorrhage from the coiled aneurysm at any time during follow-up, and clinical outcomes. RESULTS: The ULTRA Registry included 100 patients with a mean ± SD age of 56 ± 11.6 years, of whom 75 were women and 48 presented after aneurysm rupture. The mean aneurysm size was (3.5 ± 0.9) × (2.8 ± 0.9) × (3.0 ± 1.0) mm, and the mean packing density was 34.4% ± 16.7%. Posttreatment complete or near-complete occlusion reported by an independent imaging core laboratory was seen in 92% of patients at baseline and in 87%, 87%, and 83% of patients at first, second, and final follow-up, respectively. At first, second, and final follow-up, 10%, 11%, and 15%, respectively, of patients were deemed to require retreatment. There were three procedural-related ischemic strokes and one intracranial hemorrhage from wire perforation of a parent artery not involved by the aneurysm. There were no coil-related adverse events, including no intraoperative aneurysm ruptures and no known aneurysm ruptures after coiling. CONCLUSIONS: This assessment of aneurysm occlusion rates and safety profiles in ULTRA Registry study participants demonstrates excellent safety and efficacy profiles for Target Ultra and Nano coils in the treatment of small IAs.

BACKGROUND: High levels of platelet inhibition have been associated with hemorrhagic complications following Pipeline embolization of intracranial aneurysms. We therefore titrate clopidogrel dosing to maintain a moderate level of platelet inhibition using the VerifyNow P2Y12 assay. However, many patients demonstrate dramatic increases in platelet inhibition following treatment despite being on a consistent antiplatelet regimen. We therefore elected to explore the incidence of this phenomenon and possible predisposing factors. METHODS: All successful Pipeline aneurysm treatments performed at our institution from 2011 to 2019 with moderate procedure-day platelet inhibition levels as indicated by a VerifyNow PRU of 60-235 were included. Patients who received glycoprotein IIb/IIIa inhibitors and those treated for ruptured/symptomatic lesions were excluded. The incidence of excessive platelet inhibition defined by a PRU<60 within 8 weeks of treatment was noted. Multivariable logistic regression was performed to determined independent predictors of the phenomenon. RESULTS: Some 190 treatments were performed in 178 qualifying patients. A post-procedure PRU <60 occurred following 79% of treatments, documented on average after 8.5 (range 1-47) days. A higher procedure day hematocrit level (P=0.003, OR 1.09, 95% CI 1.029 to 1.152) was an independent predictor of reaching a PRU <60, while intra-procedural midazolam exposure (P=0.044, OR 0.44, 95% CI 0.201 to 0.980) and a higher procedure-day PRU (P=0.047, OR 0.99, 95% CI 0.982 to 1.000) were associated with a reduced odds. Time-since-procedure and hematocrit levels were associated with excessive platelet inhibition when excluding patients who initially demonstrated hyperresponse. CONCLUSION: Elevations in platelet inhibition were frequently observed following flow diversion with Pipeline.

BACKGROUND: Peri-procedural blood loss and hemodilution occur in patients undergoing mechanical thrombectomy (MT) for ischemic stroke; however, its relationships with thrombectomy passes, procedure times, and clinical outcomes are unknown. METHODS: Consecutive patients undergoing MT for anterior circulation large-vessel occlusion ischemic strokes were identified at a Comprehensive Stroke Center. Clinical information, modified treatment in cerebral ischemia (mTICI) scores, and modified Rankin Scores (mRS) at 90 days were prospectively collected from 2012 to 2021. Hemoglobin measurements before and after MTs were collected retrospectively via chart review, and changes were quantified. Patients with new-onset severe anemia (defined as post-MT hemoglobin less than 10g/dL) were identified. Modified Rankin scale (mRS) at 90 days was used to measure clinical outcomes. RESULTS: Four-hundred and forty-five patients were identified. Hemoglobin decreased 1.27 ± 1.05â g/dL after MT on average. Greater number of thrombectomy passes and longer procedure times were associated with larger decreases in hemoglobin (p < 0.001 and p = 0.002, respectively). 11.5% (51 of 445) of patients had new-onset severe anemia, and this incidence was significantly higher with more thrombectomy passes (6.4% for one pass, 11.9% for two passes, and 17.4% for three or more passes; p = 0.010). In multivariable analyses, new-onset severe anemia was associated with significantly higher odds of 90-day poor outcomes (mRS 3-6, OR 2.70 [95%CI 1.12-6.51], p = 0.027) and death (OR 2.73 [95%CI 1.06-7.04], p = 0.037) compared to mild post-MT anemia. CONCLUSIONS: More thrombectomy passes and longer procedure times were significantly associated with larger peri-procedural decreases in hemoglobin. Patients with new-onset hemoglobin less than 10â g/dL are at risk of poor outcomes.
