{"title":"Cerebral Vasomotor Reactivity Testing in the Middle Cerebral Artery Using Transcranial Doppler to Assess Brain Dysregulation in Long-haul COVID Patients","authors":"Musharaf Mohiuddin, Thomas H. Alexander, Amanda Holcomb, Kaitlyn Alexander, George Plotkin, Alan Cook","doi":"10.1177/15443167231202560","DOIUrl":"https://doi.org/10.1177/15443167231202560","url":null,"abstract":"Introduction: COVID-19 has wide-ranging physiological effects, with many patients complaining of persistent asthenia following recovery from the acute phase of the infection. The frequent term for this is “Long-Haul COVID.” While we have tools to measure effects on general physiology in human subjects, a metric for cerebral dysregulation is lacking. Cerebral blood flow is closely regulated in a healthy young person. Cerebral vasomotor reactivity (CVR) was used as a tool to assess this dysregulation. Methods: A transcranial Doppler (TCD) study for CVR was performed under the influence of Carbogen gas. A questionnaire collected prior to the procedure provided additional details on subjects’ demographics and COVID history. Cases and controls were recruited using the self-reported questionnaire. Statistics involved assessing the reproducibility of the test, as well as discovering differences between cases and control groups. Results: Cerebral vasomotor reactivity was assessed in 26 subjects (10 cases and 16 controls). Mean flow velocity in the left middle cerebral artery was analyzed at baseline, at peak Carbogen gas exposure, and in the hypercapnic phase. The reproducibility of the test was established within the longitudinal repeated measures data. The case and control groups were insignificant in difference at the base level but significant when controlled for confounders. Cerebral vasomotor reactivity was found to increase by 3.8 units in cases compared to controls. Confounders like body mass index, gender, and age were found significantly different between cases and controls. The number of COVID episodes and symptom severity was significant for CVR. Conclusion: This simple TCD bedside test was found to be effective in assessing CVR among all the subjects and was homogenous in its effect irrespective of baseline subject differences. As a preliminary test, the test showed differences among cases and control groups. The sample for the test lacked sufficient power and observations. A bigger sample size and a subsequent longitudinal follow-up may help better understand the use of CVR to screen high-risk populations for cerebrovascular anomalies.","PeriodicalId":52510,"journal":{"name":"Journal for Vascular Ultrasound","volume":"2 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135479596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Duplex ultrasound may also be used to examine stenosis type based on measurement of intimal-medial thickness (IMT). There are, as yet, no criteria in use to define the different stenosis types based on measurement of percentage IMT (%IMT). In this study, we have examined stenosis morphology using ultrasound. We have examined consecutive DUS examinations to assess the incidence and degree of IMT and correlated %IMT with volume flow as an indicator of AVF dysfunction. Methods: Duplex ultrasound was performed as per standard of care. Volume flow was measured within the ipsilateral brachial artery. Measurements of luminal diameter and vessel wall diameter were used to calculate %IMT. Results: The study group included 156 consecutive DUS examinations demonstrating a greater than 50% AVF stenosis. Mean %IMT was 45%. There were 17 (11%) lesions where there was no measurable IMT; the remainder had measurable IMT. On receiver-operating characteristic (ROC) analysis, a %IMT of 54% predicted low flow with 62.5% sensitivity and 62.7% specificity. Conclusion: Intimal-medial thickness has a moderate predictive value in predicting volume flow. Based on our results, there are 4 lesion types: (1) lesions with no measurable intimal hyperplasia, (2) a predominantly intimal hyperplastic lesion, (3) those with nonpredominant intimal hyperplasia, and (4) those with a valve type stenosis. A value based on correlation with volume flow could be considered based on our results at 54%IMT or based on morphology at 45%IMT to distinguish between predominant and nonpredominant intimal hyperplasia groups. Including measurements of %IMT in clinical trials could further our knowledge of how lesions with no measurable IMT and those with different degrees of intimal hyperplasia respond to different percutaneous interventions. This could potentially improve outcomes for patients and target more costly treatment options where there is most benefit.","PeriodicalId":52510,"journal":{"name":"Journal for Vascular Ultrasound","volume":"431 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135863993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has led to increased emphasis on screening for these lesions. In addition, these lesions may be associated with upper extremity symptoms including claudication and pain at rest. Methods: A retrospective review of patients who were referred over a 2-year period for arm pain in the setting of suspected or proven subclavian artery stenosis or occlusion was performed. This was compared to an unmatched cohort of patients who underwent carotid artery duplex with subclavian artery duplex for other reasons. Data included measuring the interbrachial systolic pressure difference (>15 and >20 mm Hg), arm-arm index, and hand acceleration time (HAT). Results: Among the172 patients studied, 48 had subclavian artery stenosis or occlusion and 26 of these had corresponding symptoms. Female gender ( P = .012), history of coronary intervention ( P = .007), hypertension ( P = .039), and arm-arm index of <0.9 ( P = .0001) were significantly associated with subclavian artery stenosis or occlusion. A HAT of >100 milliseconds was significantly associated with symptomatic subclavian artery stenosis or occlusion. Conclusions: An arm-arm index of <0.9 is a useful tool for screening for subclavian artery stenosis. In patients with subclavian artery stenosis, HAT may be useful in confirming that the arm symptoms are due to this particular lesion.","PeriodicalId":52510,"journal":{"name":"Journal for Vascular Ultrasound","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136033993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to evaluate the contribution of Doppler ultrasound of the supra-aortic trunks in the etiological evaluation of ischemic stroke. Methods: Our cross-sectional and analytical study with retrospective and prospective data collection more than 8 years from January 1, 2010, to December 31, 2017, involved patients aged at least 21 years who were hospitalized for ischemic stroke. Doppler ultrasound of the supra-aortic trunks allowed us to group carotid atherosclerotic plaques into 5 grades according to the Gray-Weal classification modified by Geroulakos. Similarly, we assessed the degree of carotid stenosis in these patients. Factors associated with atherosclerotic plaques and stenosis were determined using multivariate logistic regression. Associations with a P < 0.1 in univariate regression were included in the multivariate model. Differences were considered significant for P < .05. Results: We recruited 271 patients with a mean age of 60 ± 12 years. Hypertension, increased low-density lipoprotein, diabetes, smoking, and obesity were present in 76.8%, 74.7%, 36.5%, 9.6%, and 80.1%, respectively. Atherosclerotic carotid plaques were found in 76.0% of the patients. For the left carotid artery, Grade I, II, and III plaques were present in 32.4%, 30.5%, and 21.4% of these patients, respectively, and the results were similar in the right carotid artery. Age ≥60 years, female gender, and increased low-density lipoprotein were significantly associated with carotid atherosclerosis (odds ratio = 12.6, P = .003; odds ratio = 3.23, P = .001; and odds ratio = 4, P = .002, respectively). Carotid stenosis ≥50% was found in 5.9% of patients with plaque, and age >70 years was significantly associated with these stenoses (odds ratio = 4.74, P = .045). Conclusion: Our study showed a high prevalence of atherosclerotic carotid plaques (76.0%) and stenosis (5.9%) among patients with ischemic strokes who had Doppler ultrasound of the neck vessels. Age is a powerful risk factor associated with carotid atherosclerosis and stenosis. Female gender and dyslipidemia are also significantly associated with carotid atherosclerotic plaques.","PeriodicalId":52510,"journal":{"name":"Journal for Vascular Ultrasound","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136280534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
