Noninvasive studies of the carotid bifurcation.

The accuracy of the noninvasive carotid system studies done in our laboratory during an 18-month period were reviewed. The usefulness of these procedures was found to be limited when used as a "blind" screen for extracranial vascular disease. The overall correlation with angiography was good, with few false-negatives and an accuracy rate of 86%. A comparison with cervical auscultation showed high false-positive rates for both methods.

Neurovascular syndromes of aortic dissection.

Dissecting aneurysm is the most common acute disease of the aorta. Men are more likely than women to develop aortic dissection. One-third of the cases show neurologic manifestations, which may be a clue to early diagnosis. Cerebral, spinal cord and peripheral nerve ischemia can occur. In general, the treatment of choice for dissection originating in the ascending aorta is prompt surgical intervention. Medical therapy to lower elevated blood pressure and to reduce the force of myocardial contractility is sufficient for dissection of the descending aorta.

Anatomic variations of the carotid bifurcation affecting doppler scan interpretation.

An anatomic variant for the position of the external carotid artery (ECA) at the carotid bifurcation was noted in 5.3 percent of patients studied by Doppler ultrasound and contrast angiography. The ECA is lateral to and posterior to the internal carotid artery (ICA) in these patients. Consideration of this important variant is mandatory for accurate ultrasound image correlation.
