Transcranial Doppler detection of anterior cerebral artery vasospasm.

The performance of transcranial Doppler in the detection of anterior cerebral artery vasospasm and vasospasm in patients after subarachnoid haemorrhage was analysed. Transcranial Doppler and cerebral angiography were performed within the same 24 hours on each of 41 patients with acute subarachnoid haemorrhage. Sensitivity and specificity of transcranial Doppler to classify middle cerebral arter...

Transcranial Doppler detection of vertebrobasilar vasospasm following subarachnoid hemorrhage.

BACKGROUND AND PURPOSE Transcranial Doppler sonography is of established value in the detection and monitoring of middle cerebral artery vasospasm. Little information exists on the utility of transcranial Doppler for detection of posterior circulation vasospasm. METHODS Cerebral angiography and conventional hand-held transcranial Doppler sonography were compared to determine sensitivity and s...

Transcranial Doppler Detection of Circulating Cerebral Emboli

Background: The identification of gaseous emboli using Doppler ultrasound was described as early as the 1960s. Recently it has been demonstrated that this method can also detect solid emboli such as thrombi and platelet aggregates. This may make this technology useful in a large number of patients with, or at risk of, embolic stroke. Summary of Review: Emboli appear as short-duration, high-inte...
