...: The role of patent foramen ovale is a field of debate and current publications have increasing controversies about the patients’ management in young undetermined stroke. Work up with echocardiography and transcranial Doppler (TCD) can aid the decision with better anatomical and functional characterization...

... and contralateral, anterior and posterior, and downstream and upstream arteries were monitored during vasospasm progression. Results: For current clinical indices that track blood velocities at vasospastic arterial segments using transcranial Doppler (TCD), we observed that velocities increased initially...

... women, age 34 ± 11 years) prospectively underwent routine history and physical exam, transcranial Doppler, brain MRI, TEE, carotid duplex, and clinical and laboratory evaluations of atherogenesis, inflammation, platelet activity, coagulation, and fibrinolysis. Subjects without stroke/TIA on enrollment...

... in patients with asymptomatic carotid stenosis including cerebrovascular reserve testing, MRI of plaque composition, ultrasound of plaque echolucency, and transcranial Doppler evaluation for microemboli. The highest quality evidence thus far in the literature includes only systematic reviews and meta-analyses...

... measurement of blood pressure together with blood flow velocities using finger plethysmography/arterial catheter and transcranial Doppler over three 10-minute recordings on days 0-2, 3-6 and ≥7 days after stroke. Transfer function analysis was applied to calculate average phase shift (PS) in the low frequency...

... of arterial BP and CBF velocity (transcranial Doppler) were performed during periods of 5 minutes, at rest, and at different levels of alveolar CO 2 pressure provided by respiratory maneuvers. The dominant frequency of CBF oscillations was determined for each patient. Dynamic CA was measured as the mean phase...

... or on cerebral blood flow impairment following the event. The aim of our study was to evaluate blood flow velocity changes in the middle cerebral arteries (MCA) after a mannitol bolus in patients with ICH. Methods: Transcranial Doppler bilateral monitoring was performed for 90 min in 20 patients with ICH, during...

... and Central America, where 18 million individuals are infected by Trypanosoma cruzi , causing congestive heart failure (CHF) and cardioembolic stroke. Transcranial Doppler (TCD) is able to detect real-time microembolic signals (MES) to the brain vessels and may represent a surrogate marker of stroke risk. We...

...-min active ECP treatment was performed. CBFV in the middle cerebral artery were detected via transcranial Doppler. CBFV were registered continuously before, during and after ECP. The protocol was repeated twice. Results: At onset of ECP, immediate changes in CBFV were observed: peak diastolic blood...

... rate and outcome in acute stroke patients. Methods: We conducted a retrospective analysis of acute stroke patients who received intravenous (IV) recombinant tissue plasminogen activator (rt-PA) and had transcranial Doppler examination within 3 h of symptom onset. The TCD findings were interpreted using...

...Jose A. Egido; Carmen Sánchez Transcranial Doppler (TCD) has become a general practice in recent years in the diagnostic study of patients with cerebral ischemia. This is due to the fact that it is a rapid, noninvasive, reproducible and dynamic examination of intracranial circulation. In the acute...

... to in the content or advertisements. Microembolic signal Transcranial Doppler Diffusion-weighted imaging The ongoing microembolic signal (MES) is an important mechanism of acute cerebral infraction in patients with large artery occlusive disease (LAOD) [ 1,2,3,4,5,6,7 ]. Emboli are associated...

... subarachnoid hemorrhage (SAH) predicts symptomatic vasospasm. However, the value of transcranial Doppler within 48 h of SAH is unknown. Methods: We analyzed 199 patients who had at least 1 middle cerebral artery (MCA) transcranial Doppler examination within 48 h of SAH onset. Abnormal MCA mean blood flow...

...Kazuto Kobayashi; Yasuyuki Iguchi; Kazumi Kimura; Yoko Okada; Yuka Terasawa; Noriko Matsumoto; Kenichirou Sakai; Jyunya Aoki; Kensaku Shibazaki Background: Contrast transesophageal echocardiography (c-TEE) and contrast transcranial Doppler (c-TCD) are useful diagnostic tools for detecting right...

...Maher Saqqur; Georgios Tsivgoulis; Carlos A. Molina; Andrew M. Demchuk; Ashfaq Shuaib; Andrei V. Alexandrov Background: We examined if transcranial Doppler (TCD) flow findings at the site of intracranial occlusions predict outcomes of stroke patients receiving intravenous rt-PA treatment. Subjects...

... of hypoperfusion. The aim of the present study was to look for predictors of carotid clamping intolerance by means of transcranial Doppler. Patients and Methods: We analysed the findings of an earlier Italian multicentre prospective study (SCITEA, Italian Cooperative Study of Transcranial Doppler in Carotid...

... whether RLS is associated with the occurrence of sudden deafness. Methods: Contrast saline transcranial Doppler ultrasonography was performed to detect RLS. Subjects comprised 23 consecutive sudden deafness patients and 46 age- and gender-matched controls. Clinical characteristics, including vascular risk...

... of 1,208 subjects aged ≧40 years, with no history of stroke, and who had undergone transcranial Doppler ultrasonography (TCD) were collected prospectively. The role of classic risk factors was assessed in the presence and severity of asymptomatic ICAS, which was determined by TCD. Results: Regarding...
