Ultrasonographic findings on postoperative day 13 (hospital day-22): A. long-axis and B. short-axis color Doppler image showing an anechoic mass without blood flow immediately above the anastomosis. In both images, a fibrous capsule around the mass was shown (cyan arrowheads). C. long-axis image showing a ligation-induced venous stenosis 1.3 mm in diameter (yellow arrowheads). (Se: seroma, Ra; radial artery, An: anastomosis, Ce: cephalic vein)

Initial and follow-up ultrasonography: A. on postoperative day 13 (hospital day 22) and B. postoperative day 26 (hospital day 35) showing little changes in size or echogenicity. (A: 4.0 cm × 1.5 cm × 0.5 cm, B: 3.7 cm × 1.4 cm × 0.5 cm) (Se: seroma, Ce: cephalic vein)
