2. Fig 1
Color Doppler ultrasonography of the pedicle confirms vascular flow (arrow) and shows some fluid (arrowhead) around the normal-appearing intrathoracic omental flap (*).

3. Fig 2
Longitudinal high-resolution gray-scale color Doppler ultrasonography 3 weeks later shows a normal-appearing omental flap. The pedicle could not be visualized due to calcification (arrow).

4. Fig 3
Contrast-enhanced computed tomography demonstrates the vessels in the pedicle (arrow) and calcifications that distorted the sonographic evaluation of the pedicle at 8 weeks after reconstructive surgery. The flap and vessels in the pedicle are both highly visible.

5. Fig 4
Longitudinal high-resolution gray-scale color-Doppler ultrasonography demonstrates some fluid (arrowhead) around the periphery of the still normal-appearing omental flap (*).

6. Fig 5
Transverse high-resolution gray-scale color-Doppler ultrasonography shows the normal appearance of an intrathoracic omental flap (*). Some fluid is seen on the periphery (arrowhead). The flap does not appear hyperechoic, and there are no hypoechoic structures present in the flap.

7. Fig 6
Longitudinal high-resolution gray-scale color Doppler ultrasonography shows a decrease of fluid (arrowhead) surrounding the intrathoracic omental flap (*) since the previous examination 1 week earlier.

8. Fig 7
Longitudinal color Doppler ultrasonography shows the arterial (red) and venous (blue) flow within the omental pedicle in the absence of infection (patient 2, 3 years later).
