To date, no ideal imaging modality exists for tracking patency of the LVA postoperatively. We hypothesize that laser angiography utilizing indocyanine green (ICG) via the SPY system (Lifecell Corp.) would be a useful methodology for assessing the patency of the LVA and lymphatic recovery postoperatively. Methods A prospective trial was performed on patients with stage II lymphedema who underwent LVA from 2013 to 2014 by a single surgeon. All candidates underwent preoperative and postoperative lymphatic mapping using ICG-SPY angiography. Postoperative analyses were performed at 1 month and at 9 months after surgery and assessed for patency at the site of the LVAs and for changes in lymphatic pattern. Results Five patients underwent LVA, 3 for upper extremity and 2 for lower extremity stage II lymphedema. The number of LVAs per extremity was 1 to 3 (total, 11). One month postoperative ICG-SPY angiography demonstrated flow through 9 of 11 anastomoses. Evaluation at 9 months postoperative showed improvement in lymphatic drainage. Conclusions Indocyanine green-SPY angiography may be used to objectively evaluate the surgical outcome of LVA. Supplemental digital content is available in the text.
