Doppler ultrasound assessment of the internal carotid artery following carotid endarterectomy.

Doppler ultrasound assessment of the internal carotid artery following carotid endarterectomy.

Doppler-shifted ultrasound with spectral analysis was used to assess the internal carotid arteries of 48 patients who had undergone carotid endarterectomy (58 carotid endarterectomies). Three patients died in the immediate post-operative period, therefore 45 patients, who represented 54 endarterectomies, were assessed for up to six years following surgery (mean--thirty-four months). Ultrasound ...

What happens to the external carotid artery following carotid endarterectomy?

AIMS The effect of carotid endarterectomy on the patency of the external carotid artery is unknown. We conducted a retrospective study to evaluate the long-term changes in the external carotid artery following carotid endarterectomy. METHODS Data was prospectively recorded for all patients who had carotid endarterectomy between 1997 and 2006 in our vascular surgical unit. These patients had f...

Internal Carotid Artery Web: Doppler Ultrasound with CT Angiography correlation.

We present a case of an internal carotid web, detected on duplex ultrasound and confirmed by CT angiography. To our knowledge, this is only the third reported ultrasound case in the imaging literature. This vascular abnormality can cause a clinically significant carotid stenosis and is a risk factor for recurrent embolic cerebrovascular events. Due to small size and poor awareness among radiolo...

Internal carotid artery occlusion diagnosed by Doppler ultrasound.

Internal Carotid Artery Occlusion Diagnosed by Doppler Ultrasound • Using a transcutaneous Doppler ultrasonic blood velocity detector, retrograde ophthalmic artery blood flow was demonstrated in four patients, all of whom had angiographically confirmed occluded internal carotid arteries. In three, compression of the facial artery obliterated the ophthalmic artery signal. In a fourth patient com...
