Flap Perfusion

Introduction: Breast skin flap ischemia and necrosis is a serious consequence of breast reconstruction with reported incidence of 10% to 15%. Current clinical method of assessing breast skin flap perfusion includes combination of skin color, temperature, dermal edge bleeding, and capillary refill. Given the high incidence of ischemia and the presence of certain cohort of patient with greater risk, there is a need for an objective method of assessing the skin flap perfusion. Near infrared fluorescence imaging using indocyanine green is a new technique of assessing skin flap perfusion. We present a first reported case where breast skin flap ischemia was objectively identified intraoperatively by NIRF imaging, and this ischemia was reversed through active intra- and postoperative measures, which was objectively again identified by NIRF imaging. Case presentation: A 36-year-old female patient underwent bilateral nipple sparing mastectomies with immediate reconstruction using tissue expanders. Clinical assessment of the breast skin flap was equivocal. NIRF imaging using SPY imaging system (Novadaq Technologies Inc, Toronto, ON, Canada) showed poor perfusion in the periareolar region. As a result, it was decided to completely deflate the expander, actively warm the skin flap and encourage cutaneous perfusion through use of topical glycerin trinitrate patch. A repeat NIRF imaging 48 hours showed 10-fold increase in perfusion in the skin flap. Conclusion: NIRF imaging is a useful tool in assessing breast skin perfusion and to predict potential ischemia, which can aid in surgeon's management of patient.

Laparoscopic surgery for patients with a horseshoe kidney is challenging because of the location, aberrant vasculature, and difficulty with division of the isthmus with adequate hemostasis. We herein report performance of a laparoscopic heminephrectomy for left ureteral cancer in a patient with a horseshoe kidney under guidance from near-infrared fluorescence (NIRF) imaging using indocyanine green (ICG). A 62-year-old male was referred to our hospital for treatment of left ureteral cancer associated with a horseshoe kidney. We performed a laparoscopic left nephroureterectomy and bladder resection in June 2017. During the operation, the NIRF imaging system was used to evaluate the border of the kidney parenchyma isthmus after ligation of the left kidney vasculature supply. Interestingly, the dominant region of the right kidney showed strong ICG fluorescence as compared to the left kidney region. With the assistance of ICG-based NIRF imaging, isthmus division was performed with monopolar scissors and adequate hemostasis was obtained by electrocautery coagulation. This is the first report of use of an ICG-based NIRF imaging system and this novel approach can help to demarcate the left moiety isthmus from right one with more certainty.
