In an acute stroke setting, transcranial Doppler (TCD) and transcranial color-coded duplex (TCCD) have an important diagnostic utility in the monitoring of an arterial occlusion and microemboli detection. In addition, TCD has proven to be a very useful tool in the detection and progression of cerebral vasospasm in patients with subarachnoid hemorrhage. TCD/TCCD may have an important role in defining collateral blood flow (CF) in stroke patients. It is a noninvasive technique and can be utilized repeatedly allowing for changes in the blood flow dynamics as treatment is delivered. In this review, we outlined the evolving role of TCD/TCCD in defining CF in patients with an acute ischemic stroke, predicting clinical outcome and monitoring the treatment's efficacy of the CF augmentation.

“…Proximal artery stenosis could induce more primary/secondary collateral blood ow to compensate for the loss of main blood circulation. Secondary collaterals such as leptomeningeal anastomoses could dilate and leak contrast material [30]. In this case, meningeal enhancement could be considered a predictor of the risk for proximal stenosis.…”

Purpose: This study aimed to find predictors of stroke in patients with tuberculous meningitis.Methods: This systematic review and meta-analysis were done using literature searches through online databases up to April 30th, 2022. Three independent authors performed literature screening, data extraction, and critical appraisal of the studies. Eight studies involving 1535 samples were included.Results: We analyzed data regarding demographic, comorbidity, clinical presentation, radiologic, and laboratory parameters. Overall, clinical presentation that showed outcome difference was found in patients with findings of vomiting (OR = 2.71, 95% CI: 1.30-5.63), cranial nerve deficit (OR = 4.10, 95% CI: 1.83-9.21), focal deficit (OR = 5.56, 95% CI: 2.24-13.79), and altered consciousness (OR = 1.90, 95% CI: 1.24-2.92). Some comorbidities showed significant differences such as diabetes mellitus (OR = 2.58, 95% CI: 1.51-4.41), hypertension (OR = 5.73, 95% CI: 3.36-9.77), ischemic heart disease (OR = 2.18, 95% CI: 1.02-4.63), and smoking (OR = 2.65, 95% CI: 1.22-5.77). Two radiological changes shown to have significantly higher proportions are hydrocephalus (OR = 2.50, 95% CI: 1.74-3.58) and meningeal enhancements (OR = 3.99, 95% CI: 1.73-9.20).Conclusion: Our analysis indicated that clinical presentations of vomiting, cranial nerve deficit, focal deficit, altered consciousness; comorbidity of diabetes mellitus, hypertension, smoking history, ischemic heart disease; and radiological findings of meningeal enhancement and hydrocephalus showed significant association with stroke incidence in tuberculous meningitis.

Points 1. TCD/TCCD may have an important role in defining collateral blood flow (CF) in stroke patients and monitoring of CBF. 2. It is a noninvasive technique and can be utilized repeatedly allowing for changes in the blood flow dynamics as treatment is delivered. 3. The criteria of CBF on TCD and TCCD have been developed and verified. 4. TCD/TCCD is unique monitoring tool of CBF in an acute stroke setting. 5. TCD/TCCD has an evolving role as monitoring tool of therapeutic efficacy in CBF augmentation.
