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.

Abstract Background This study aims to directly compare measurements of tissue oxygenation obtained using the Intra.Ox (Vioptix Inc., Fremont, CA) near infrared spectrometer with the perfusion assessment of the indocyanine green (ICG)-based SPY Elite imaging system (Stryker Co., Kalamazoo, MI) in a porcine bowel model. Methods Two live minipigs underwent laparotomy and isolation of a 30-cm segment of a large bowel. Standardized oximetry measurements were taken along the segment of bowel immediately before, after, and serially for 30 minutes following transection. A 0.5 mg/kg dose of ICG was then injected intravenously and the SPY Elite system was used to visualize and quantify tissue perfusion. Pearson's correlation coefficients were calculated using the outcomes. Results Transected and ligated bowel yielded mean Intra.Ox measurements of 61% oxygenation at the proximal base of the limb and 27.8% at the distal edges. Analysis of the relative ICG fluorescence using the SPY Elite's proprietary software yielded perfusion estimates of 64.8% proximally and 6.8% distally. Intra.Ox and SPY Elite measurements demonstrate a Pearson product–moment correlation of 0.929. Repeat measurements at 15-mm intervals along the tissue yielded decreasing Intra.Ox measurements along the length of the flap that correlate to SPY Elite measurements (r = 0.645). Conclusion Both the Intra.Ox and the SPY detected clinically relevant changes in bowel oxygenation following transection and ligation. The use of intravenous ICG dye did not appear to affect measurements of tissue oxygenation obtained using the Intra.Ox.

Paraclinoid Aneurysms

Background: Paraclinoid aneurysms are a challenging type of intracranial aneurysms due to their surrounding anatomy. Residual aneurysm after microsurgical clipping carries a risk of aneurysm growth and rupture. Microscope-integrated near-infrared indocyanine green angiography (ICGA) is a new technique that allows for real-time evaluation of blood flow in the aneurysm and vessels. It is increasingly utilized to confirm optimal clip positioning across the neck and to evaluate the adjacent vasculature. Objective: To explore the intraoperative research of neuroimaging assessment of neck residuals and patency of branches for paraclinoid aneurysms using the indocyanine green angiography (ICGA) technique in the surgery. Methods: From January 2009 to December 2014, a retrospective study to evaluate the intraoperative value of ICGA in patients who underwent microsurgical clipping of paraclinoid aneurysms was performed. Intraoperative ICGA was performed using a fluorescence microscope before and after clipping. After the operation, three-dimensional CT angiography (CTA), digital substraction angiography (DSA) were used to evaluate the use of intraoperative ICGA. The presence and patency of the parent artery and perforating artery around the aneurysm, and the information of aneurysm were analyzed in the surgical field through intraoperative imaging. These findings of ICGA were compared with those of postoperative DSA or CTA. Results: The study included 69 cases of adults and three out of them were noted as having significantly changed information provided by intraoperative ICGA. After initial clip placement, neck remnants of the aneurysm were found in 1 patient, inadvertent clipping of branching vessels in 2 patients, and inadvertent clipping of perforating vessels in two patients. After adjusting the aneurysm clipping, no such unexpected findings as parent or branching artery occlusion, or aneurysm sac omission were found on postoperative angiograms. The postoperative DSA and CTA results were consistent with the intraoperative ICGA findings. Conclusions: Microscope-integrated ICGA is useful in the clipping of paraclinoid aneurysms to monitor residual aneurysm, parent artery stenosis or perforating artery occlusion during paraclinoid aneurysm clipping. A combination of ICGA and microsurgical techniques may ultimately prove to be the most effective strategy for maximizing the safety and efficacy of aneurysm surgery.
