Background and Purpose: Restenosis after carotid endarterectomy (CEA) is associated with an increased risk of ipsilateral stroke. The optimal procedural modality for this indication has yet to be determined. Here, we evaluate the in-hospital outcomes of transcarotid artery revascularization (TCAR), redo-CEA, and transfemoral carotid artery stenting (TFCAS) in a large contemporary cohort of patients who underwent treatment for restenosis after CEA. Methods: We performed a retrospective analysis of all patients in the vascular quality initiative database who underwent TCAR, redo-CEA, or TFCAS after ipsilateral CEA between September 2016 and April 2020. Patients with prior ipsilateral CAS were excluded from this analysis. In-hospital outcomes following TCAR versus CEA and TCAR versus TFCAS were evaluated using multivariate logistic regression analysis. Results: A total of 4425 patients were available for this analysis. There were 963 (21.8%) redo-CEA, 1786 (40.4%) TFCAS, and 1676 (37.9%) TCAR. TCAR was associated with lower odds of in-hospital stroke/death (odds ratio [OR], 0.41 [95% CI, 0.24–0.70], P =0.021), stroke (OR, 0.46 [95% CI, 0.23–0.93], P =0.03), myocardial infarction (MI; OR, 0.32 [95% CI, 0.14–0.73], P =0.007), stroke/transient ischemic attack (OR, 0.42 [95% CI, 0.24–0.74], P =0.002), and stroke/death/MI (OR, 0.41 [95% CI, 0.24–0.70], P =0.001) when compared with redo-CEA. There was no significant difference in the odds of death between the 2 groups (OR, 0.99 [95% CI, 0.28–3.5], P =0.995). TCAR was also associated with lower odds of stroke/transient ischemic attack (OR, 0.37 [95% CI, 0.18–0.74], P =0.005) when compared with TFCAS. There was no significant difference in the odds of stroke, death, MI, stroke/death, or stroke/death/MI between TCAR and TFCAS. Conclusions: TCAR was associated with significantly lower odds of in-hospital stroke, MI, stroke/transient ischemic attack, stroke/death, and stroke/death/MI when compared with redo-CEA and lower odds of in-hospital stroke/transient ischemic attack when compared with TFCAS. Additional long-term studies are warranted to establish the role of TCAR for the treatment of restenosis after CEA.

Abstract OBJECTIVE: Clinical and experimental evidence suggests that hyperglycemia lowers the neuronal ischemic threshold, potentiates stroke volume in focal ischemia, and is associated with morbidity and mortality in the surgical critical care setting. It remains unknown whether hyperglycemia during carotid endarterectomy (CEA) predisposes patients to perioperative stroke and operative related morbidity and mortality. METHODS: The clinical and radiological records of all patients undergoing CEA and operative day glucose measurement from 1994 to 2004 at an academic institution were reviewed and 30-day outcomes were assessed. The independent association of operative day glucose before CEA and perioperative morbidity and mortality were assessed via multivariate logistic regression analysis. RESULTS: One thousand two hundred and one patients with a mean age of 72 ± 10 years (748 men, 453 women) underwent CEA (676 asymptomatic, 525 symptomatic). Overall, stroke occurred in 46 (3.8%) patients, transient ischemic attack occurred in 19 (1.6%), myocardial infarction occurred in 19 (1.6%), and death occurred in 17 (1.4%). Increasing operative day glucose was independently associated with perioperative stroke or transient ischemic attack (Odds ratio [OR], 1.005; 95% confidence interval [CI], 1.00–1.01; P = 0.03), myocardial infarction (OR, 1.01; 95% CI, 1.004–1.016; P = 0.017), and death (OR, 1.007; 95% CI, 1.00–1.015; P = 0.04). Patients with operative day glucose greater than 200 mg/dl were 2.8-fold, 4.3-fold, and 3.3-fold more likely to experience perioperative stroke or transient ischemic attack (OR, 2.78; 95% CI, 1.37–5.67; P = 0.005), myocardial infarction (OR, 4.29; 95% CI, 1.28–14.4; P = 0.018), or death (OR, 3.29; 95% CI, 1.07–10.1; P = 0.037), respectively. Median and interquartile range length of hospitalization was greater for patients with operative day glucose greater than 200 mg/dl (4 d [interquartile range, 2–15 d] versus 3 d [interquartile range, 2–7 d]; P < 0.05). CONCLUSION: Independent of previous cardiac disease, diabetes, or other comorbidities, hyperglycemia at the time of CEA was associated with an increased risk of perioperative stroke or transient ischemic attack, myocardial infarction, and death. Strict glucose control should be attempted before surgery to minimize the risk of morbidity and mortality after CEA.

Leg Movements

Background: Periodic leg movements during sleep (PLMS) have been associated with an increased risk for cardiovascular diseases and there is a high prevalence of PLMS found in patients with obstructive sleep apnea syndrome (OSAS). We evaluated patients with transient ischemic attack (TIA) for PLMS and respiratory related leg movements (RRLM), versus a control group without TIA. Methods: Twenty-five patients with TIA and 34 patients with no vascular diagnosis were referred for polysomnography. Diagnosis of PLMS was made if the periodic leg movement index (PLMI) was ≥5 and clinical significant as PLMI ≥15. Results: There was no significant difference in PLMI ≥5 and ≥15 between patients with and without TIA. In the absence of OSAS, 2 out of 5 TIA patients (40%) had a PLMI ≥15 compared to 1 of the 19 patients without TIA (5%; p = 0.037). There was no increase in RRLMs when OSAS was present. Conclusions: TIA patients did not have higher PLMI compared to controls, and in the presence of OSAS, there was no increase in RRLMs compared to patients without TIA. In selective patients, PLMS could be associated with cardiovascular diseases, since PLMS was clinically more often found in the TIA group without OSAS.

Objective Carotid stenosis with crescendo-transient-ischemic-attack (cTIA) requires a prompt intervention to reduce the stroke risk. Few data are reported in literature about cTIA suggesting a different perioperative risk compared with patients with single TIA (sTIA). This study aimed to compare the outcome of carotid endarterectomy (CEA) in patients with TIA (single/crescendo) and evaluate the outcome risk-factors. Methods Data from two tertiary hospitals for vascular treatment were analyzed from 2007 to 2016. All patients with TIA subjected to CEA were considered, comparing the 30-day postoperative stroke and stroke/death in patients with cTIA and sTIA, particularly in the urgent (≤48 h) setting. Results On a total of 3866 CEA, 888 (23%) were performed in symptomatic patients and 515 for TIA: 365 (71%) patients with sTIA and 150 (29%) with cTIA. When compared with sTIA, cTIA patients were younger and less frequently affected by coronary disease, dyslipidemia, and chronic pulmonary disease; however, contralateral carotid occlusion was more common (20% vs. 10%, P = .004; 56% vs. 46, P = .03; 16% vs. 7%, P = .01; >80 years 26% vs. 16%, P = .01 and 2% vs. 10%, P = .001; respectively). Postoperative stroke and stroke/death were significantly higher in cTIA compared with sTIA (5.3% vs. 1.6%, P = .02 and 6.0% vs. 2.2%, P = .03; respectively). Urgent CEA was performed in 58% ( n: 87) cTIA and in 11% ( n: 56) sTIA( P<.01). The urgent setting did not influence the stroke and stroke/death rate of CEA for sTIA (3.6% vs. 1.3%, P = .21 and 3.6% vs. 1.9%, P = .44, respectively), but was associated with lower rate of events in cTIA (1.1%vs. 11.1%, P = .01 and 2.3% vs. 11.1%, P = .03, respectively). This beneficial effect in patients with cTIA treated within 48-h was confirmed also by multivariate analysis (OR: 0.09, 95% CI: 0.76–0.01, P=.02). Conclusions cTIA subjected to CEA have a higher stroke and stroke/death risk compared with patients with sTIA. The urgent setting seems to reduce the stroke/death rate cTIA; for sTIA with a stable neurological condition, the timing of CEA did not influence the outcome.

Hemophilia A in females accounts for few cases due to hemophilia A and B having X-linked recessive inheritance patterns. Hemostatic changes in pregnancy include an increase in coagulation factors and von Willebrand activity, placing hemophilia patients at an increased risk for Postpartum Hemorrhage (PPH). General recommendations include considering pharmacologic prophylaxis, including tranexamic acid and factor replacement when necessary. The ultimate goal is to prevent uncontrolled bleeding during vaginal or operative delivery. Benefits of prophylactic therapies must be weighed with relevant risk profiles of each intervention. We present a case where a parturient with hemophilia prophylactically treated with TXA and FVIII experienced a transient ischemic attack. We discuss the background information known regarding tranexamic acid and factor replacement, and the subsequent recommendations for their use in this patient population. We consider recommendations to expand the multidisciplinary team incorporated in the assessment and planning for the peripartum care of such a patient.

Background: Intra-arterial or intravenous platelet glycoprotein (GP) IIb/IIIa inhibitors have been used as adjunct to stent placement of carotid stenosis in patients with ischemic stroke or transient ischemic attack. Objective: To determine the proportion of patients with ischemic stroke or transient ischemic attack who received platelet GP IIb/IIIa inhibitors as adjunct to carotid stent placement and associated outcomes. Methods: We analyzed data from Cerner Health Facts® which collected data from participating facilities from January 1, 2000 to July 1, 2018. We identified patients with ischemic stroke or transient ischemic attack who underwent carotid stent placement for carotid stenosis and received Abciximab, Eptifibatide, or Tirofiban. Outcome was defined by discharge destination and classified into none to minimal disability, moderate to severe disability, or death. Results: A total of 8.4 % of 4567 patients with ischemic stroke or transient ischemic attack who underwent carotid stent placement for carotid stenosis received platelet GP IIb/IIIa inhibitors. Patients who received platelet GP IIb/IIIa inhibitors were more likely to experience cerebral ischemia (14.8% versus 7.5%) and undergo intubation/mechanical ventilation (4.4% versus 2%). There was a significant difference between patients who did or did not receive platelet GP IIb/IIIa inhibitors in terms of in hospital mortality rates (2.7% versus 1.2%, p=0.0152), none to mild disability (67.3% vs 75.7%, p=0.0003), and moderate to severe disability (30.1% vs 23.1%,p=0.0024). Conclusions: Adjunct use of platelet GP IIb/IIIa inhibitors in patients undergoing carotid stent placement for symptomatic carotid stenosis was associated with increased rates of in hospital mortality and moderate to severe disability.

Background and Purpose— We aimed to determine the long-term risks of a motor vehicle collision after a cerebrovascular event and whether the risks were similar after left- or right-hemispheric events. Methods— We used a population-based registry to identify patients diagnosed with a transient ischemic attack or stroke (hemorrhagic or ischemic) between 2003 and 2013 in Ontario, Canada. Hemispheric laterality was determined using radiological and clinical findings. We identified subsequent serious injuries involving the patient as a driver using linked administrative data. Secondary outcomes included serious injuries involving the patient as a pedestrian, as a passenger, or other traumatic events (fall, fracture, ankle sprain). We used proportional hazard models accounting for death as a competing risk to test the association of hemispheric laterality and outcomes with and without adjustment for age, sex, discharge modified Rankin Scale score, home location, and prior driving record. Patients were followed through to 2017. Results— Among 26 144 patients with hemispheric cerebrovascular events, 377 subsequent serious traffic injuries as a driver (2.2 per 1000 person-year) were identified over a median follow-up of 6.4 person-years. The rate did not differ by laterality (adjusted hazard ratio, 1.00; 95% CI, 0.82–1.23). The risk of a serious traffic injury as a pedestrian was significantly higher after a right-sided than left-sided event (adjusted hazard ratio, 1.27; 95% CI, 1.02–1.58). Subsequent risks for other traumatic injuries did not differ by laterality of cerebrovascular event. Conclusions— The risk of a serious traffic injury as a pedestrian is substantially higher after a right-hemispheric cerebrovascular event compared with a left-sided event. Walking should be promoted for exercise in survivors of a stroke or transient ischemic attack, but these vulnerable road users may benefit from additional poststroke rehabilitation to optimize safety.

Introduction: Distal hyperintense vessels (DHV) detected by FLAIR imaging are not uncommon in patients with acute ischemic stroke. The presence of DHV and its predictors has been scarcely evaluated in patients with transient ischemic attack (TIA), being associated to the presence of large vessel occlusion in such patients. We assessed the hypothesis that DHV are frequent in patients with TIA and do correlate with relevant clinical and neuroimaging characteristics. Methods: We evaluated a database of consecutive patients admitted with TIA from February 2009 to June 2012 who had undergone magnetic resonance imaging within 30 h of symptoms onset and intracranial and extracranial vascular imaging. We analyzed the relationship between DHV, clinical presentation, risk factors, neuroimaging characteristics and large artery stenosis or occlusion. DHV signals were defined on FLAIR images as focal, linear or serpentine, hyperintense signals relative to gray matter. Two neuroradiologists blinded to clinical information reached consensus regarding the presence of DHV. Results: Seventy-two TIA patients were enrolled. The median time from symptoms onset to MRI was 8:39 h [4:21, 14:13]. DHV signals on FLAIR images were present in 12 (16.7 %) patients. The overall agreement between examiners was good (k 0.67). Patients with DHV had more atrial fibrillation (AF) than those without (41.7% versus 21.7%, p=0.05) and a trend towards more congestive heart failure (CHF) (8.3% versus 1.7%, p=0.2) and diabetes (41.7% versus 21.7%, p=0.1). There were no differences in the frequency of intracranial or cervical arterial stenosis, cerebral microbleeds and white matter abnormalities in patients with and without DHV. In a multivariate logistic regression analysis, only AF had a trend to be a predictor of DHV (OR=4.24, p=0.1). The statistical model to predict DHV including AF, diabetes, and CHF had a moderate fit in terms of discrimination (c statistic=0.62) Conclusion: DHV signals on FLAIR images occur in patients with TIA and might correlate with clinical variables like AF and not only with large vessel occlusion as previously described. The presence of DVH in patients with TIA and AF might be a surrogate marker for a previous large vessel occlusion spontaneously recanalized.

Introduction: Given the high prevalence of obesity around the globe, patients with coronavirus disease 2019 (COVID-19) are at an increased risk of devastating complications. Hypothesis: We hypothesize that morbid obesity is independently associated with increased risk of in-hospital mortality, upgrade to intensive care unit, invasive mechanical ventilation(IVM), and acute renal failure necessitating dialysis. Methods: A retrospective cohort study was performed to determine the association of basal metabolic index (BMI) with the above-mentioned outcomes. Independent t-test and multivariate logistic regression analysis were performed to calculate mean differences and adjusted odds ratios (aOR) with its 95% confidence interval (CI), respectively. Results: A total of 176 patients with confirmed COVID-19 diagnosis were included. The mean age was 62.2 years, with 51% of male patients. The mean BMI for non-surviving patients was significantly higher compared to patients surviving on the 7th day of hospitalization (35 vs. 30 kg/m2, p=0.022) and patients with a higher BMI had higher in-hospital mortality (21% vs. 9%, OR 3.2, 95% CI 1.3-8.2, p=0.01) compared to patients with a normal BMI. Similarly, patients requiring IMV had a higher BMI (33 vs. 29, p=0.002) compared to non-intubated patients. aOR of patients needing IMV (56% vs. 28%, OR 3.3, 95% CI 1.6-7.0, p=0.002) and upgrade to ICU (46% vs. 28%, OR 2.2, 1.07-4.6, p=0.04) were significantly higher compared to patients with a lower BMI. There was no significant difference between the two groups in terms of the need for dialysis (5% vs. 13%, OR 3.8, 13% vs. 4%, 1.1-14.1, p=0.07). Adjusted odds ratios controlled for baseline comorbidities and medications mirrored the overall results, except for the need to upgrade to ICU. Conclusions: In patients with confirmed COVID-19, morbid obesity serves as an independent risk factor of high in-hospital mortality and the need for invasive mechanical ventilation.
