["Erroneous orthograde" direction of flow in the supratrochlear artery as a cause of Doppler ultrasound diagnostic error in severe (filiform; 90%) stenosis of the carotid bifurcation].
Author reports on mistake in Ultrasound-Doppler-Sonography by an neurologist. A 82-year-old women with leftside Amaurosis fugax was referred by her family doctor, internist. Neurological examination, above all Doppler-Sonography, results in "normal findings". Examination by author however detected filiforme stenosis of left internal carotid artery in spite of "orthograde" direction of blood-flow in final branches of ophthalmic artery. This perhaps was the cause of neurological misdiagnosis.
