Some imaging modalities have been reported to be useful for intraoperative identification of the lymphatic vessels, but they have limitations. In this article, we present new capabilities of intraoperative laser tomography, which was used to evaluate the lumen of the lymphatic vessel and to validate the patency of anastomosis.<\/jats:p><jats:p>Methods\u2003Fifty-two patients with upper extremity lymphedema secondary to breast cancer treatment underwent indocyanine green (ICG) lymphography and real-time laser tomography imaging of ICG-enhanced lymphatic vessels intraoperatively before transecting the vessels during LVA. The imaging findings of the lymphatic vessels in laser tomography were investigated. Time required for scanning of the lymphatic vessels was compared between laser tomography and ultrasonography. The correlation between the thickness of the lymphatic vessel wall measured with laser tomographic imaging and the histologically measured thickness of the lymphatic vessel wall was examined. The patency of anastomosis sites was determined based on the image using laser tomography immediately after establishment of LVA.<\/jats:p><jats:p>Results\u2003A total of 132 ICG-enhanced lymphatic vessels were scanned with laser tomography showing clear lumen with surrounding vessel wall. The required time for lymphatic vessel scanning was significantly shorter with laser tomography than with ultrasonography (1.6\u2009\u00b1\u20090.3 vs. 4.8\u2009\u00b1\u20091.2\u2009minutes; p\u2009=\u20090.016). Strong correlation was seen between the thickness of the lymphatic vessels wall measured using laser tomography and the histologically measured thickness of the lymphatic vessel wall (r\u2009=\u20090.977, 95% confidence interval: 0.897\u20130.992, p\u2009&lt;\u20090.001). The quality of patency was evaluated immediately after anastomosis, which assisted in deciding whether reanastomosis was needed.<\/jats:p><jats:p>Conclusion\u2003Microscope-integrated laser tomography provides real-time images of the lymphatic vessels in extremely high resolution and enables evaluation of lymphatic lumen condition and objective post-LVA anastomosis status.<\/jats:p>","DOI":"10.1055\/s-0040-1718549","type":"journal-article","created":{"date-parts":[[2020,10,15]],"date-time":"2020-10-15T05:19:55Z","timestamp":1602739195000},"page":"427-435","source":"Crossref","is-referenced-by-count":21,"title":["Intraoperative Real-Time Visualization of the Lymphatic Vessels Using Microscope-Integrated Laser Tomography"],"prefix":"10.1055","volume":"37","author":[{"given":"Akitatsu","family":"Hayashi","sequence":"additional","affiliation":[{"name":"Department of Lymphedema Center, Kameda General Hospital, Chiba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidehiko","family":"Yoshimatsu","sequence":"additional","affiliation":[{"name":"Department of Plastic Surgery, Cancer Institute Hospital of the JFCR, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0041-5420","authenticated-orcid":false,"given":"Giuseppe","family":"Visconti","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, University Hospital \u201cA.
