1 Assessment of internal thoracic artery graft with intraoperative color doppler ultrasonography 
Katsushi Oda, MD, Kunihiko Hirose, MD, Hideaki Nishimori, MD, Koji Sato, MD, Toshiyuki Yamashiro, MD, Shohei Ogoshi, MD, PhD  The Annals of Thoracic Surgery  Volume 66, Issue 1, Pages (July 1998) DOI: /S (98)

2 Fig 1 Comparison of the standard 2.5 MHz probe (top) and the microprobe (bottom). The Annals of Thoracic Surgery  , 79-81DOI: ( /S (98) )

3 Fig 2 Intraoperative assessment by the microprobe. Small arrows indicate the ITA graft, and the large arrow indicates the microprobe. The Annals of Thoracic Surgery  , 79-81DOI: ( /S (98) )

4 Fig 3 The internal thoracic artery graft is clearly visualized by color Doppler imaging, and patency of the graft is easily confirmed. The Annals of Thoracic Surgery  , 79-81DOI: ( /S (98) )

5 Fig 4 A typical waveform for the internal thoracic artery graft showing biphasic, diastolic-predominant flow signal in the midportion of the graft (A) and systolic-predominant flow in the proximal portion (B). (D = diastole; S = systole.) The Annals of Thoracic Surgery  , 79-81DOI: ( /S (98) )
