Two Cases with Free-Floating Thrombus in the Common Carotid Artery
نویسندگان
چکیده
Two patients had multiple embolic infarctions in the middle cerebral artery territory. Free-floating thrombi adherent to plaques were detected in the common carotid artery near the bifurcation using duplex ultrasonography. Further strokes did not occur under anticoagulation. The free-floating thrombi disappeared on follow-up sonography. Carotid duplex ultrasonography is useful for recognizing free-floating arterial thrombi and for monitoring dynamic changes. Treatment of these thrombi remains controversial; however anticoagulation alone may be sufficient to prevent further strokes.
