Segmentectomy using indocyanine green (ICG) has become a primary treatment option to achieve a complete resection and preserve lung function in early-stage lung cancer. However, owing to a lack of appropriate intraoperative imaging systems, it is a huge challenge for surgeons to identify the intersegmental plane during the operation, leading to poor prognosis. Thus, we developed a novel wireless wearable fluorescence image-guided surgery system (LIGHTEN) for fast and accurate identification of intersegmental planes in human patients...

Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG). However, the dynamic process and mechanism of fluorescence IOC have not been elucidated in previous publications. Herein, the optical properties of the complex of ICG and bile, dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated. The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration...

PATIENTS AND METHODS: A consecutive case study of 140 patients presenting with CNV was conducted in nine large referral eye centers throughout Thailand. The demographic data, fundus photographs, fundus fluorescein angiography and indocyanine green angiography of the patients were analyzed...

BACKGROUND: Superficial mycotic skin infections which are predominantly caused by Trichophyton rubrum, poorly responses to conventional therapies. A great amount of attention has focused on to find more effective treatments. The current work is aimed to compare the effectiveness of phoinactivation of Trichophyton rubrum by two relatively new photosensitizers: a phenothiazinium dye(New methylene blue) and Indocyanine green (EmunDo(®)). MATERIALS AND METHODS: A Final inoculum of T...

BACKGROUND: The radical resection of parasagittal meningiomas without complications and recurrences is the goal of the neurosurgeon. Nowadays, different managements are proposed. This study describes our surgical technique during the lesional excision and the reconstruction of the superior sagittal sinus (SSS). METHODS: The total removal (Simpson I and II) of parasagittal meningiomas (WHO grade I and II) was obtained in 75 patients from September 2000 to January 2010...

Antitumor therapy in the elderly is particularly challenging due to multiple, often chronic diseases, poly-therapy, and age-related physiological changes that affect drug efficacy and safety. Furthermore, tumors may become more aggressive and drug-resistant with advanced age, leading to poor patient prognosis. In this study, we evaluated in mice bearing medulloblastoma xenografts the effect of age on tumor progression and tumor therapy. We focused on therapeutic efficacy of two treatment modalities alone radiofrequency ablation therapy (RFA), PEGylated liposomal doxorubicin (PLD) equivalent to Doxil, and their combination...

OBJECTIVE: Currently, lymphedema (LED) is typically diagnosed clinically on the basis of a patient's history and characteristic physical findings. Whereas the diagnosis of LED is sometimes confirmed by lymphoscintigraphy (LSG), the technique is limited in both its ability to identify disease and to guide therapy. Recent advancements provide opportunities for new imaging techniques not only to assist in the diagnosis of LED, based on anatomic changes, but also to assess contractile function and to guide therapeutic intervention...

BACKGROUND: Metastatic involvement of the sentinel lymph node (SLN) represents a key prognostic factor in melanoma. The combined use of a radiocolloid (technetium-99m) and blue dye is the gold standard in sentinel lymph node biopsy (SLNB). In this context, near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) has been suggested as an alternative. The objective of the present study was to examine the potential advantages of fluorescence-guided SLNB - compared to the conventional method - with respect to the visualization of lymphatic drainage pathways and the SLN...

BACKGROUND: The inability to visualize the patient and surgical site directly, limits the use of current near infrared fluorescence-guided surgery systems for real-time sentinel lymph node biopsy and tumor margin assessment. METHODS: We evaluated an optical see-through goggle augmented imaging and navigation system (GAINS) for near-infrared, fluorescence-guided surgery. Tumor-bearing mice injected with a near infrared cancer-targeting agent underwent fluorescence-guided, tumor resection...

Most solid cancers spread to new sites via the lymphatics before hematogenous dissemination. However, only a small fraction of an intravenously administered anti-cancer drug enters the lymphatic system to reach metastatic lymph nodes (LNs). Here, we show that the enhanced permeability and retention (EPR) effect is not induced during the early stages of LN metastasis. Luciferase-expressing tumor cells were injected into the subiliac LN of the MXH10/Mo-lpr/lpr mouse to induce metastasis to the proper axillary LN (PALN)...

INTRODUCTION: Identification of lymph nodes and pathological analysis is crucial for the correct staging of colon cancer. Lymph nodes that drain directly from the tumor area are called "sentinel nodes" and are believed to be the first place for metastasis. The purpose of this study was to perform sentinel node mapping in vivo with indocyanine green and ex vivo with methylene blue in order to evaluate if the sentinel lymph nodes can be identified by both techniques. METHODS: Patients with colon cancer UICC stage I-III were included from two institutions in Denmark from February 2015 to January 2016...

Near-infrared fluorescence imaging in endocrine surgery is a new, yet highly investigated area. It involves indocyanine green use as well as parathyroid autofluorescence. Several groups have described their technique and reported on the observed utility. However, there is no consensus on technical details. Furthermore, the correlation between intraoperative findings and postoperative outcomes is unclear. With this study, we aim to review the current literature on fluorescence imaging and share our insights on technical details...

A 65-year-old Caucasian male presented to the eye emergency department with bilateral significant visual loss. He was otherwise healthy with no significant past medical history. Ophthalmic history was significant for chronic open-angle glaucoma, for which the patient was using latanoprost once daily to both eyes. There was no preceding history of trauma or ocular surgery and the patient was emmetropic. Two weeks prior to his presentation, he reported a headache, which settled spontaneously. Slit-lamp examination demonstrated bilateral keratic precipitates, bilateral significantly shallow anterior chamber, and bilaterally normal intraocular pressures of 16 mm Hg...

OBJECTIVE: To describe a new stage of multiple evanescent white dot syndrome (MEWDS), occurring at a very early phase of the disease. METHODS: Retrospective analysis of clinical, angiographic and tomographic findings in four patients with 'hyper-early' stage MEWDS. RESULTS: In four patients seen within 1 week of the onset of symptoms, fundus analysis revealed macular granity and the classic yellow-white dots, some having no corresponding hyperautofluorescent pattern...

meso-Aryl substituted expanded porphyrins have two potential key features suitable for theranostic agents, excellent absorption in near infrared (NIR) region and possible introduction of multiple fluorine atoms at structurally nearly equivalent positions. Herein, hexaphyrin (hexa) was synthesized using 2,6-bis(trifluoromethyl)-4-formyl benzoate and pyrrole and evaluated as a novel theranostic expanded porphyrin possessing the above key features. Under NIR light illumination hexa showed intense photothermal and weak photodynamic effects, which were most likely due to its low-lying excited states close to a singlet oxygen...

OBJECTIVE: To describe the anatomy of uterine lymphatic drainage following cervical or fundal tracer injection to enable standardization of a pelvic sentinel lymph node (SLN) concept in endometrial cancer (EC). METHODS: A prospective consecutive study of women with EC was conducted. A fluorescent dye (Indocyanine green) was injected into the cervix (n=60) or the uterine fundus (n=30). A systematic trans- and retroperitoneal mapping of uterine lymphatic drainage was performed...
