Incidence of Visualized Thyroid Abnormalities During Carotid Duplex EvaluationsBend Memorial Clinic Vascular Laboratory, 1501 NE Medical Center Drive, Bend, OR 97701. rpscissons{at}hotmail.com
Bend Memorial Clinic Vascular Laboratory, Bend, Oregon
Vascular Laboratory, Providence Surgical Care, Providence, Rhode Island. The objective of this study was to determine the incidence of thyroid abnormalities detected in patients referred for clinically indicated carotid duplex Doppler sonography examinations. Data from 327 consecutive initial carotid sonography examinations performed at two institutions were analyzed. Institution A was a vascular surgery office in the eastern United States; Institution B was a multispecialty clinic in the western United States. Visualized thyroid abnormalities in Institution A represented 51 of 192 patients (27%); females had the majority (65%), and 18% (9/51) described a prior history of thyroid disease. Thyroid anomalies in Institution B were 47 of 135 patients (35%), with near-equal gender distribution (49% female; 51% male), and 26% (12/47) had a prior history of thyroid disease. Most affected patients were not aware of their thyroid abnormalities. The reporting of incidental findings may seriously affect patient management and therefore should not be overlooked.
