Sir:

We appreciate the valuable comments and perspective of Yoshimatsu et al.1 regarding our recent article2 describing the results of axillary lymph node transplantation with noncontrast magnetic resonance lymphography in 15 patients with secondary upper limb lymphedema. In this article, we demonstrated that distal dilated lymphatic vessels in the arm were observed in four patients (Fig. 1).2

In their letter, Yoshimatsu et al. indicated that identification of dilated lymphatic vessels before lymphaticovenular anastomosis remains a challenge despite visualization of such dilated vessels with magnetic resonance lymphography. They described a new method for identification of lymphatic vessels using ultrasonography after vigorous pumping from the underlying muscles in the upper extremity.1

We definitely agree with the comments by Yoshimatsu et al. As a matter of fact, the standard of reference for detection of the lymphatic channels in the upper extremity is indocyanine green lymphography.3 However, limitations of indocyanine green lymphography include a relatively small field of view and markedly limited penetration depth.4 Therefore, indocyanine green lymphography cannot be used to analyze deep lymphatic vessels.4 Ultrasonography is uncommonly performed to demonstrate dilated lymphatic vessels in patients with lymphedema.5 In their letter, Yoshimatsu et al. propose an innovative method for improving detection of lymphatic vessels with ultrasonography by means of a pumping movement of the underlying muscles. Nevertheless, the ideal technique for identification of dilated lymphatic vessels remains elusive. We assume that a multimodality approach could be used—including magnetic resonance lymphography, indocyanine green lymphography, and ultrasonography—if the preliminary results of Yoshimatsu et al. are confirmed.1 These authors should be commended for their innovative technique.
