Treatment of carotid stenosis has evolved significantly since the … Depending on the location of the aneurysm, ECCAs can be classified into five types.4,8 Because the surgical options vary depending on this classification, it is important to describe the location of the ECCAs in the ultrasound report. Currently, duplex ultrasound is the most cost effective screening method for carotid diagnosis. In the present case report, the maximum AP diameter of the ICA aneurysm was 562% of the AP diameter of the non-aneurysmal ICA and 244% larger than the AP diameter of the non-aneurysmal CCA. The patient underwent an elective open repair of the aneurysm with aneurysmectomy and an end-to-end arterial anastomosis between the CCA and ICA with 5–0 prolene. The transducer emits sound waves and records the echo as the waves bounce off tissues, organs and blood cells.
