1 Intraoperative ultrasonographic localization of pulmonary ground-glass opacities 
Ryoichi Kondo, MD, PhD, Kazuo Yoshida, MD, PhD, Kazutoshi Hamanaka, MD, Masahiro Hashizume, MD, Toshiki Ushiyama, MD, Akira Hyogotani, MD, Makoto Kurai, MD, Satoshi Kawakami, MD, Mana Fukushima, MD, Jun Amano, MD, PhD  The Journal of Thoracic and Cardiovascular Surgery  Volume 138, Issue 4, Pages (October 2009) DOI: /j.jtcvs Copyright © 2009 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 A CONSORT flow diagram for the criteria used to enroll patients in this study. Twenty-nine of the patients who agreed to participate could not subsequently be examined by intraoperative ultrasonography because the ultrasonogram device was unavailable. Forty-four patients were eventually enrolled. GGOs, Ground-glass opacities; CT, computed tomography; VATS, video-assisted thoracic surgery; COPD, chronic obstructive pulmonary disease.

3 Figure 2 Intraoperative ultrasonographic image of an entirely deflated lung in which the structures of the lung parenchyma could be visualized. The pulmonary arterioles and venules revealed a homogeneous hypoechoic area. Asterisks indicate bronchioles that appear as hyperechoic spots in the vicinity of the pulmonary arterioles.

4 Figure 3 A, Intraoperative ultrasonographic image of a ground-glass opacity. The white arrow indicates forceps placed near to the edge of the tumor. B, Electrocautery marking on the visceral pleura was performed around the target lesions using ultrasonographic views of the ground-glass opacity.
