Cerebrovascular reserve capacity (CVRC) is a hemodynamic parameter indicating the brain’s capacity to overcome ischemia. Transcranial Doppler (TCD) is a useful device to measure CVRC, with high availability and low cost. The aim of the study is to investigate asymptomatic patients with affected CVRC, who could benefit from CEA. One hundred and forty five consecutive patients (60 symptomatic and 65 asymptomatic), with internal carotid artery (ICA) stenosis >70 % and 20 healthy individuals without internal carotid stenosis underwent TCD-inhalation CO2 tests in order to measure the CVRC in both hemispheres of each patient. CVRC between asymptomatic and symptomatic patients were significantly different in the 95 % confidence interval (CI) as well as the mean CVRC value in contralateral carotid artery. The correlation between CVRC in the carotid artery with stenosis and the existence of symptoms is significant at the 0.01 level. Additionally, symptoms and CVRC of the contralateral carotid artery are also significant at the 0.05 level and CVRC values in asymptomatic patients and the control group at the 0.01 level. None of the covariant factors, except the age, are significantly correlated with CRVC. CVRC could be an early mark-index to evaluate the risk of stroke in this group of patients and to design their therapeutic approach.

The efficacy of intravenous thrombolysis and endovascular therapy and their favorable treatment outcomes have been established in clinical trials irrespective of age. Current guidelines do not recommend an age limit in selecting eligible patients for reperfusion treatment as long as other criteria are satisfied. A 103-year-old woman was admitted at our hospital within 1 h of stroke onset secondary to a left internal carotid artery terminus occlusion. On admission, her National Institutes of Health Stroke Scale (NIHSS) score was 30, with a small left thalamic diffusion restriction lesion on MRI. Her medical history included paroxysmal atrial fibrillation, prior myocardial infarction, hypertension, chronic kidney disease, and diabetes mellitus. Her pre-stroke modified Rankin Scale score was 0, and she was fully independent before stroke. Once intravenous thrombolysis was started, the patient successfully underwent mechanical thrombectomy, and thrombolysis in cerebral infarction-3 recanalization was achieved 225 min after symptom onset. She showed dramatic recovery (NIHSS score of 5 after 48 h) and was discharged on day 7 with a modified Rankin Score of 1. To our knowledge, our patient is the second oldest documented patient who successfully underwent bridging therapy for stroke.
