Abstract Background Indocyanine green (ICG) lymphangiography is being increasingly employed to assess the severity of lymphedema, locate the areas of patent linear lymphatics and dermal backflow and plan treatment. This study suggests a novel method of reporting ICG findings in extremities to enable easy understanding among surgeons and physiotherapists and avoid repeat testing when a patient visits a disparate lymphedema center or clinician. Methods A reporting protocol was developed in the lymphedema clinic of the plastic surgery department, and patients were asked to bring along the report in every subsequent review. The ICG findings were recorded on the fluorescence imaging system as well. The report was prepared by one and analyzed by two different clinicians without repeating the test on 10 consecutive patients. Results The interrater reliability of findings in the report was found to be 98.7% among the three clinicians. Conclusion The reporting system was found to be illustratable and reproducible

IntroductionIn-vivo fluorescence imaging techniques using indocyanine green (ICG) to identify liver tumours and hepatic segment boundaries have been recently developed. The purpose of this study is to evaluate the efficacy of fusion ICG-fluorescence imaging for navigation during hepatectomy.Methods and analysisThis will be an exploratory single-arm clinical trial; patients with liver tumours will undergo hepatectomy using the ICG-fluorescence imaging system. In total, 110 patients with liver tumours scheduled for elective hepatectomy will be included in this study. Preoperatively, ICG will be intravenously injected at a dose of 0.5 mg/kg body weight within 2 days. To detect liver tumours intraoperatively, the hepatic surface will be initially observed using the ICG-fluorescence imaging system. After identifying and clamping the portal pedicle corresponding to the hepatic segments, including the liver tumours to be resected, additional ICG will be injected intravenously at a dose of 0.5 mg/kg body weight to identify the boundaries of the hepatic segments. The primary outcome measure will be the success or failure of the ICG-fluorescence imaging system in identifying hepatic segments. The secondary outcomes will be the success or failure in identifying liver tumours, liver function indicators, operative time, blood loss, rate of postoperative complications and recurrence-free survival. The findings obtained through this study are expected to help to establish the utility of ICG-fluorescence imaging systems, and therefore contribute to prognostic outcome improvements in patients undergoing hepatectomy for various causes.Ethics and disseminationThe protocol has been approved by the Kobe University Clinical Research Ethical Committee. The findings of this study will be disseminated widely through peer-reviewed publications and conference presentations.Trial registration numberUMIN000031054 and jRCT1051180070

Introduction Fluorescence imaging with indocyanine green is used in urology for the detection of sentinel lymph nodes and identification of prostate margins in radical prostatectomy for delineation of resection zone and selective clamping of vessels in partial nephrectomy; for identification and evaluation of length of ureteral strictures; for assessment of perfusion and viability of anastomoses during reconstructive stage of cystectomy. Safety of this technique is proven, while its diagnostic value and usefulness is still controversial. Methods This pilot study of using the SPY Elite Fluorescence Imaging System for diagnostics was performed in the I.M. Sechenov First Moscow State Medical University. Ten patients were enrolled: four patients underwent retropubic RP and lymph node dissection, five patients underwent partial nephrectomy, and one patient underwent ureteroplasty. Fluorophore was injected transrectally with TRUS guidance during RP in order to assess the lymph nodes. During partial nephrectomy, the compound was injected intravenously to differentiate the tumor from parenchyma by its blood supply. During ureteroplasty, the indocyanine green solution was injected into the renal pelvis to dye the ureter and locate the stricture. Results Sensitivity of this technique for visualization of sentinel lymph nodes was 100%, and specificity was 73.3%. In patients who underwent partial nephrectomy, all lesions were malignant and hypofluorescent when compared with healthy parenchyma. SPY allowed us to determine the location and extension of the stricture during ureteroplasty. No hypersensitivity reactions or complications were observed during injection of the compound.

The authors report the case of a 78-year-old man with a craniocervical junction epidural arteriovenous fistula who presented with subarachnoid hemorrhage from a ruptured anterior spinal artery (ASA) aneurysm. Because endovascular embolization was difficult, a posterolateral approach was chosen and a novel endoscopic fluorescence imaging system was utilized to clip the aneurysm. The fluorescence imaging system provided clear and magnified views of the ventral spinal cord simultaneously with the endoscope-integrated indocyanine green videoangiography, which helped safely obliterate the ASA aneurysm. With the aid of this novel imaging system, surgeons can appreciate and manipulate complex vascular pathologies of the ventral spinal cord through a posterolateral approach, even when the lesion is closely related to the ASA.
