RESUMO
Background White matter hyperintensity (WMH) has been linked to poor clinical outcomes after acute ischemic stroke. Purpose To assess whether the WMH burden on pretreatment MRI scans is associated with an increased risk for symptomatic intracranial hemorrhage (sICH) or poor functional outcome in patients with acute ischemic stroke treated with endovascular thrombectomy (EVT). Materials and Methods In this retrospective study, consecutive patients treated with EVT for anterior circulation acute ischemic stroke at a comprehensive stroke center (where MRI was the first-line pretreatment imaging strategy; January 2015 to December 2017) were included and analyzed. WMH volumes were assessed with semiautomated volumetric analysis at fluid-attenuated inversion recovery MRI by readers who were blinded to clinical data. The associations of WMH burden with sICH and 3-month functional outcome (modified Rankin Scale [mRS] score) were assessed. Results A total of 366 patients were included (mean age, 69 years ± 19 [SD]; 188 women [51%]). Median total WMH volume was 3.61 cm3 (IQR, 1.10-10.83 cm3). Patients demonstrated higher mRS scores with increasing WMH volumes (odds ratio [OR], 1.020 [95% CI: 1.003, 1.037] per 1.0-cm3 increase for each mRS point increase; P = .018) after adjustment for patient and clinical variables. There were no significant associations between WMH severity and 90-day mortality (OR, 1.007 [95% CI: 0.990, 1.024]; P = .40) or the occurrence of sICH (OR, 1.001 [95% CI: 0.978, 1.024]; P = .94). Conclusion Higher white matter hyperintensity burden was associated with increased risk for poor 3-month functional outcome after endovascular thrombectomy for large-vessel occlusive stroke. © RSNA, 2022 Online supplemental material is available for this article.

OBJECTIVES: To establish whether collateral circulation was associated with functional outcome in stroke patients with large infarct size (Alberta Stroke Program Early CT Score [ASPECTS] ≤ 5) undergoing endovascular thrombectomy (EVT) METHODS: Consecutive patients with acute ischemic stroke due to large-vessel occlusion in the anterior circulation and an ASPECTS of ≤ 5 were analyzed. Quantification of collateral circulation was performed using a fluid-attenuated inversion recovery vascular hyperintensity (FVH)-ASPECTS rating system (score ranging from 0 [no FVH] to 7 [FVHs abutting all ASPECTS cortical areas]) by two independent neuroradiologists. Good functional outcome was defined by modified Rankin Scale (mRS) score of 0 to 3 at 3 months. We determined the association between FVH score and clinical outcome using multivariable regression analyses. RESULTS: A total of 139 patients (age, 63.1 ± 20.8 years; men, 51.8%) admitted between March 2012 and December 2017 were included. Good functional outcome (mRS 0-3) was observed in 65 (46.8%) patients, functional independence (mRS 0-2) was achieved in 43 (30.9%) patients, and 33 (23.7%) patients died at 90 days. The median FVH score was 4 (IQR, 3-5). FVH score was independently correlated with good outcome (adjusted OR = 1.41 [95% CI, 1.03-1.92]; p = 0.03 per 1-point increase). CONCLUSIONS: In stroke patients with large-volume infarcts, good collaterals as measured by the FVH-ASPECTS rating system are associated with improved outcomes and may help select patients for reperfusion therapy. KEY POINTS: ⢠Endovascular thrombectomy can allow almost 1 in 2 patients with large infarct cores to achieve good functional outcome (modified Rankin Scale [mRS] of 0-3) and 1 in 3 patients to regain functional independence (mRS 0-2) at 3 months. ⢠The extent of FVH score (as reflected by FLAIR vascular hyperintensity [FVH]-Alberta Stroke Program Early CT Score [ASPECTS] values) is associated with functional outcome at 3 months in this patient group.

BACKGROUND AND PURPOSE: White matter hyperintensity (WMH), a marker of chronic cerebral small vessel disease, might impact the recruitment of leptomeningeal collaterals. We aimed to assess whether the WMH burden is associated with collateral circulation in patients treated by endovascular thrombectomy for anterior circulation acute ischemic stroke. METHODS: Consecutive acute ischemic stroke due to anterior circulation large vessel occlusion and treated with endovascular thrombectomy from January 2015 to December 2017 were included. WMH volumes (periventricular, deep, and total) were assessed by a semiautomated volumetric analysis on fluid-attenuated inversion recovery-magnetic resonance imaging. Collateral status was graded on baseline catheter angiography using the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology grading system (good when ≥3). We investigated associations of WMH burden with collateral status. RESULTS: A total of 302 patients were included (mean age, 69.1±19.4 years; women, 55.6%). Poor collaterals were observed in 49.3% of patients. Median total WMH volume was 3.76 cm3 (interquartile range, 1.09-11.81 cm3). The regression analyses showed no apparent relationship between WMH burden and the collateral status measured at baseline angiography (adjusted odds ratio, 0.987 [95% CI, 0.971-1.003]; P=0.12). CONCLUSIONS: WMH burden exhibits no overt association with collaterals in large vessel occlusive stroke.

OBJECTIVES: To establish whether imaging assessments of irreversibly injured ischemic core and potentially salvageable penumbral volumes and collateral circulation were associated with functional outcome in nonagenarians (90 years or older) undergoing endovascular thrombectomy (EVT). METHODS: Data from a prospectively maintained institutional registry of consecutive stroke patients treated with EVT from January 2012 to December 2018 were retrospectively analyzed. Functional outcome was evaluated with the modified Rankin scale (mRS) at 3 months. mRS score of 0-3 was defined as a good clinical outcome. Ischemic core and penumbral volumes were calculated using the RAPID software. Quantification of collateral circulation was performed using a fluid-attenuated inversion recovery vascular hyperintensity (FVH)-Alberta Stroke Program Early CT Score (ASPECTS) rating system. RESULTS: Among 85 patients (age, 92.4 ± 2.6 years; men, 30.6%) treated with EVT, good outcome (mRS 0-3) was achieved in 29 (34.1%) patients and 31 (36.5%) patients died at 90 days. The median estimated ischemic core volume was 15 mL (IQR, 7-27 mL). The median mismatch volume was 83 mL (IQR, 43-120 mL). The median FVH score was 4 (IQR, 3-4). FVH score was independently associated with good functional outcome (adjusted OR = 1.96 [95% CI, 1.16-3.32]; p = 0.01 per 1-point increase) and mortality (adjusted OR = 0.54 [95% CI, 0.34-0.85]; p = 0.007 per 1-point increase). Ischemic core and mismatch volumes were associated with neither good outcome nor mortality. CONCLUSIONS: In nonagenarians with anterior circulation large-vessel ischemic stroke, good collaterals as measured by the FVH-ASPECTS rating system are independently associated with improved outcomes and may help select patients for reperfusion therapy in this frail population. KEY POINTS: ⢠Endovascular thrombectomy can allow at least 1 in 3 patients older than 90 years of age to achieve good functional outcome (modified Rankin scale of 0-3) at 3 months. ⢠Functional outcome at 3 months is associated with pre-stroke status (number and severity of patients' comorbidities). ⢠A higher FVH score (as reflected by higher FLAIR vascular hyperintensity [FVH]-Alberta Stroke Program Early CT Score [ASPECTS] values) is independently associated with better 3-month functional outcome and mortality in nonagenarians with anterior circulation ischemic stroke.

BACKGROUND AND PURPOSE: The benefit of endovascular thrombectomy (EVT) among nonagenarians (90 years or older) is poorly documented. We aimed to investigate the clinical and imaging factors associated with good outcomes and mortality at 90 days in nonagenarians undergoing EVT for acute ischemic stroke (AIS). METHODS: Data from a prospectively maintained institutional registry of consecutive AIS patients treated with EVT from January 2012 to December 2018 were retrospectively analysed. Comorbid conditions were classified with a modified version of the Charlson Comorbidity Index (CCI). The degree of disability was assessed by the modified Rankin Scale (mRS). Outcomes included good functional outcome (mRS scores of 0-3) and mortality at 90 days. RESULTS: Among 110 patients (age, 92.3 ± 2.5 years; men, 28.2%) treated with EVT, good outcome was achieved in 39 (35.5%) patients, successful reperfusion (modified Thrombolysis in Cerebral Infarction grades of 2b-3) was achieved in 78 (70.9%) patients and 38 (34.5%) patients died at 90 days. The functional outcome at 3 months was associated with pre-stroke status (CCI and pre-stroke mRS score). Successful reperfusion (adjusted odds ratio [OR], 11.6; 95% CI, 1.3-104.2; P = 0.03) and early neurologic improvement at 24 h (adjusted OR, 16.4; 95% CI, 5.2-51.5; P < 0.001) were independent predictors of a good outcome. Early neurological improvement (adjusted OR, 0.06; 95% CI, 0.02-0.23; P < 0.001) was an independent predictor of 90-day mortality. CONCLUSIONS: Successful reperfusion therapy improves the functional outcome of nonagenarians who should not be excluded from EVT. The presence and severity of comorbidities should be considered in the procedural management of this vulnerable population.

INTRODUCTION: The ever expanding advances in various domains of cardiac and endovascular interventions has drawn tremendous attention toward the importance of the anatomical variability and morphometric parameters of the aortic arch (AA) and its branches. METHODS: The current study delineates the morphometry and anatomical variations of the AA branches by evaluating coronal, axial and sagittal CT multiplanar reformatted three-dimensional angiograms. Correlations between morphometric data as well as the distribution of morphometric data in relation to the anatomical variations were also illustrated. RESULTS: 35% of the examined AA showed abnormal branching patterns, the most common of which was the "bovine arch" (24%), followed by common ostium variant (6%) and aberrant left vertebral artery arising directly from AA (5%). The outer diameter of AA at its origin and its end was 33.83 and 22.06 mm, respectively. The distance between the origin of AA and the origin of brachiocephalic trunk (BCT), left common carotid artery (LCCA) and left subclavian artery (LSA) was 19.59, 23.01 and 26.01 mm, respectively. The outer diameter of BCT, LCCA and LSA was 15.7, 11.42 and 14.02 mm, respectively. The angles between the AA and the BCT, LCCA and LSA were 59.01°, 68.59° and 59.92°, respectively. The mean distance between the BCT and LCCA was 19.59 mm and the distance between the LCCA and the LSA was 23.01 mm. Significant positive and negative correlations between morphometric data as well as the distribution of morphometric parameters in relation to the anatomical variations have been identified. CONCLUSION: The illustrated anatomical variations and morphometric data provide cardinal information especially for patients undergoing aortic endovascular intervention, principally for choosing the size, shape and type of the angiographic catheters and devices to be delivered.

INTRODUCTION: Increasing administrative workload is linked with lower quality of patient care and physician burnout. Conversely, models involving pharmacists can positively impact patient care and physician well-being. Research has consistently demonstrated that pharmacist-physician collaboration can improve outcomes for chronic diagnoses. Pharmacist-managed refill services may improve provider workload measures and clinical outcomes. METHODS: This was an evaluation of a pharmacist-managed refill service at a Federally Qualified Health Center (FQHC). Under collaborative practice agreement, pharmacists addressed refill requests and recommended interventions. Data analysis evaluated effectiveness of the model, including clinical interventions, and involved descriptive statistics and qualitative approaches. RESULTS: Average patient age was 55.5 years old and 53.1% were female. Turnaround time was within 48 h for 87.8% of refill encounters. During an average of 3.2 h per week, pharmacists addressed 9.2% (n = 1683 individual requests in 1255 indirect patient encounters) of the total clinic refill requests during the 1-year study period. In 453 of these encounters (36.1%), pharmacists recommended a total of 642 interventions. 64.8% of these were need for appointment (n = 211) or labs (n = 205). Drug therapy problems and medication list discrepancies were identified in 12.6% (n = 81) and 11.9% (n = 76) of encounters, respectively. DISCUSSION AND CONCLUSIONS: The results of this study are consistent with previous literature demonstrating the value of interprofessional collaboration. Pharmacists addressed refills in an efficient, clinically effective manner in an FQHC setting. This may positively impact primary care provider workload, patients' medication persistence, and clinical care.

BACKGROUND: Evidence about the safety and the efficacy of flow diversion for distal anterior cerebral artery (DACA) aneurysms is scant. To provide further insight into flow diversion for aneurysms located at, or distal to, the A2 segment. METHODS: Consecutive patients receiving flow diversion for DACA aneurysms were retrieved from our prospective database (2014-2020). A PRISMA guidelines-based systematic review of the literature was performed. Aneurysm occlusion (O'Kelly-Marotta=OKM) and clinical outcomes were evaluated. RESULTS: Twenty-three patients and 25 unruptured saccular DACA aneurysms treated with flow diversion were included. Aneurysm size ranged from 2 mm to 9 mm (mean size 4.5 mm, SD ±1.6). Mean parent artery diameter was 1.8 mm (range, 1.2-3 mm, SD ±0.39). Successful stent deployment was achieved in all cases. Angiographic adequate occlusion (OKM C-D) at follow-up (14 months) was 79% (19/24 available aneurysms). No cases of aneurysm rupture or retreatment were reported. Univariate analysis showed a significant difference in diameter among aneurysms with adequate (4 mm) vs incomplete occlusion (7 mm) (P=0.006).There was one transient perioperative in-stent thrombosis, and three major events causing neurological morbidity: two stent thromboses (one attributable to the non-adherence of the patient to the antiplatelet therapy); and one acute occlusion of a covered calloso-marginal artery.Results from systematic review (12 studies and 107 A2-A3 aneurysms) showed 78.6% (95% CI=70-86) adequate occlusion, 7.5% (95% CI=3.6-14) complications, and 2.8%, (3/107, 95% CI=0.6-8.2) morbidity. CONCLUSIONS: Flow diversion among DACA aneurysms is effective, especially among small lesions. However, potential morbidity related to in-stent thrombosis and covered side branches should be considered when planning this strategy.

OBJECTIVE: To determine whether pretreatment cerebral microbleeds (CMBs) presence and burden are correlated with an increased risk of intracranial hemorrhage (ICH) or poor functional outcome following endovascular thrombectomy (EVT) for acute ischemic stroke (AIS). METHODS: Consecutive patients treated by EVT for anterior circulation AIS were retrospectively analyzed. Experienced neuroradiologists blinded to functional outcomes rated CMBs on T2*-MRI using a validated scale. We investigated associations of CMB presence and burden with ICH and poor clinical outcome at 3 months (modified Rankin Scale score >2). RESULTS: Among 513 patients, 281 (54.8%) had a poor outcome and 89 (17.3%) had ≥1 CMBs. A total of 190 (37%) patients experienced ICH; 66 (12.9%) were symptomatic. CMB burden was associated with poor outcome in a univariable analysis (odds ratio [OR], 1.18; 95% confidence interval [CI], 1.03-1.36 per 1-CMB increase; p = 0.02), but significance was lost after adjustment for sex, age, stroke severity, hypertension, diabetes mellitus, atrial fibrillation, prior antithrombotic medication, IV thrombolysis, and reperfusion status (OR, 1.05; 95% CI, 0.92-1.20 per 1-CMB increase; p = 0.50). Results remained nonsignificant when taking into account CMB location or presumed underlying pathogenesis. CMB presence, burden, location, or presumed pathogenesis were not independently correlated with ICH. CONCLUSIONS: Poor functional outcome or ICH were not correlated with CMB presence or burden on pre-EVT MRI after adjustment for confounding factors. Excluding such patients from reperfusion therapies is unwarranted. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that in patients with AIS undergoing EVT, after adjustment for confounding factors, the presence of CMBs is not significantly associated with clinical outcome or the risk of ICH.

BACKGROUND: Clinical and hemodynamic consequences of flow diverters extending from the M1 to the internal carotid artery (ICA), covering the A1 segment, have rarely been investigated. We aimed to provide angiographic and clinical data about flow modifications on the covered A1. METHODS: Consecutive patients receiving M1-ICA flow diverters for unruptured aneurysms were collected from our prospective database (2014-2020). RESULTS: 42 A1 arteries covered with a single device were studied. All patients had an angiographic detected contralateral flow from the anterior communicating artery (AcomA). Immediately after flow diversion, 20 (47.6%) covered A1 showed slow flow. During a mean angiographic follow-up of 14 months, 13 (31%) and 22 (52.3%) A1 arteries were occluded and narrowed, respectively. Flow changes were asymptomatic in all cases. Vascular risk factors, sex, oversized compared with not oversized stents, immediate A1 slow flow, age, diameter of the A1, length of follow-up, and platelet inhibition rate were tested as prognosticators of A1 occlusion. Length of the angiographic follow-up was the only predictor of A1 occlusion (p=0.005, OR=3, CI=1.4 to 6.7). There were two device related ischemic events with a 2.3% rate of morbidity (one basal ganglia infarct after coverage of the M1 perforators and one transient acute instent thrombosis). CONCLUSIONS: Covering the A1 segment during M1-ICA flow diversion seems relatively safe, if the contralateral flow is assured by the AcomA. Approximately 31% and 52% of the covered A1 showed asymptomatic occlusions and narrowing, respectively. The likelihood of flow modification was proportional to the length of follow-up. Morbidity associated with flow diversion in the ICA terminus region was 2.3%.

BACKGROUND: It is debated whether endovascular treatment is indicated for a symptomatic chronically occluded internal carotid artery (COICA). OBJECTIVE: To assess outcomes after endovascular treatment of COICA. METHODS: We performed a systematic search of three databases (PRISMA guidelines), including endovascular series of COICA. Outcomes were analyzed with random-effects models. RESULTS: We included 13 studies and 528 endovascularly treated patients with COICA. Successful recanalization was 72.6% (347/528, 95% CI 65.4% to 79.9%, I2=68.9%). Complications were 18% (88/516, 95% CI 12.1% to 23.8%, I2=65%), with 5% (25/480, 95% CI 2% to 7%, I2=0%) of permanent events, and 9% (43/516, 95% CI 6% to 13%, I2=34%) of thromboembolisms. Treatment-related mortality was 2% (11/516, 95% CI 0.5% to 2.6%, I2=0%). Shorter duration of the occlusion was associated with higher recanalization: 80% (11/516, 95% CI 54% to 89%, I2=0%), 63% (33/52, 95% CI 49% to 76%, I2=0%), and 51% (18/35, 95% CI to 37% to 88%, I2=40%) recanalization rates for 1, 3, and >3 months occlusions, respectively. Complications were 6% (3/50, 95% CI 3% to 21%, I2=0%), 14% (4/27, 95% CI 5% to 26%, I2=0%), and 25% (13/47, 95% CI 10% to 30%, I2=0%) for 1, 3, and >3 months occlusions, respectively. Patient aged <70 years presented higher revascularization rates (OR=3.1, 95% CI 1.2 to 10, I2=0%, p=0.05). Successful reperfusion was higher (OR=5.7, 95% CI 1.2 to 26, I2=60%, p=0.02) and complications were lower (OR=0.2, 95% CI 0.6 to 0.8, I2=0%, p=0.03) for lesions limited to the cervical internal carotid artery compared with the petrocavernous segment. Successful recanalization significantly lowered the rate of thromboembolisms (OR=0.2, 95% CI 0.8 to 0.6, I2=0%, p=0.01) and mortality (OR=0.5, 95% CI 0.1 to 0.9, I2=0%, p=0.04), compared with conservative treatment. CONCLUSIONS: Endovascular treatment of COICA gives a 70% rate of successful recanalization, with 5% morbidity. Patients aged <70 years, lesions limited to the cervical internal carotid artery, and a shorter duration of the occlusion decreased the risk of complications. Successful recanalization of symptomatic lesions lowered by about 80% the likelihood of thromboembolisms, compared with medical management.

OBJECTIVES: To assess the relation of sex hormone levels in men, as measured by Free Androgen Index (FAI), with severity of erectile dysfunction (ED) and with their response to treatment. METHODS: We retrospectively reviewed the medical records of men who consecutively attended the urology clinic with the complaint of ED between March 2004 and October 2007. The Sexual Health Inventory for Men (SHIM) score was used as the main outcome measure in this study, and its variation was tested by certain variables using the Epi Info software. RESULTS: A total of 150 men were studied. The majority of patients (93%) had FAI in the normal range levels, and had shown no relation to the SHIM score even after adjustment for other factors. However, FAI was highly related to patients' response to treatment, with the higher the level the higher was the proportion of patients responded well to treatment. Age of the patient was the only factor influencing the SHIM score they could attain, as shown by the linear regression analyses. CONCLUSION: The FAI level is not related to the severity of ED. Its role however, is confined to the way patients are going to respond to medical treatment of ED. Further studies are therefore needed to assess the effectiveness of using this parameter as a reliable test of bioactive testosterone for men with ED.

BACKGROUND AND OBJECTIVE: Labor pain is one of the most severe forms of pain that women experience throughout their lifetime. Many pregnant women decide to have an epidural anesthesia to cope with labor pain. This study has focused on general awareness about epidural anesthesia among pregnant women in Jeddah, Saudi Arabia. METHODS: This was a cross-sectional hospital-based study using a self-administered questionnaire, conducted in King Faisal Specialist Hospital and Research Center and International Medical Centre. The study was carried out from July to September 2016 and included all pregnant women who were having a routine antenatal care. They were asked about four main topics that tapped their knowledge on epidural anesthesia. A total of 384 questionnaires were returned and analyzed. Data were analyzed by SPSS version 21 using chi-square and multivariate logistic regression. RESULTS: According to multivariate logistic regression, women aged between 21-35 years were more likely to opt for an epidural anesthesia (EPA) than those aged less than 20 years, but women aged >35 years were less likely to select EPA, compared with women < 20 years old. Women who were previously exposed to EPA were 2.14 times more likely to prefer EPA during their current pregnancy than those who were not previously exposed (O.R 95% C.I: 1.123-3.66, p=0.006). Those who believed that EPA was commonly used by other women in the Kingdom were also 1.41 times more likely to report their preference to EPA (O.R 95% C.I: 1.15-1.74, p=0.001). CONCLUSION: This study demonstrates a lack of knowledge about EPA in certain countries but is better than in some other countries. In an aim to fill this gap, it is recommended that information about EPA must be given to all women during the antenatal visit either by the obstetrician, anesthetist, or through flyers and brochures.
