BACKGROUND: Lymphatic mapping to guide sentinel lymph node biopsy (SLNB) typically requires lymphoscintigraphy prior to surgery. In young pediatric patients, this process often requires intubation in the nuclear medicine suite followed by transport to the operating room (OR). METHODS: We reviewed 14 pediatric cases in which a portable nuclear imaging camera was utilized to perform the entirety of the SLNB in the OR. RESULTS AND CONCLUSION: This method, utilizing intraoperative nuclear imaging, helped to confirm removal of the sentinel lymph node in real time, decreased anesthesia time, and avoided transport of a sedated or intubated child...

BACKGROUND: Once interruption of transmission of lymphatic filariasis is achieved, morbidity prevention and management becomes more important. A study in Brugia malayi filariasis from India has shown sub-clinical lymphatic pathology with potential reversibility. We studied a Wuchereria bancrofti infected population, the major contributor to LF globally. METHODS: Children aged 5-18 years from Odisha, India were screened for W. bancrofti infection and disease. 102 infected children, 50 with filarial disease and 52 without symptoms were investigated by lymphoscintigraphy and then randomized to receive a supervised single oral dose of DEC and albendazole which was repeated either annually or semi-annually...

We report the case of a 19-year-old man who presented with a 12-year history of progressive fatigue, feeling hot, excessive sweating, and numbness in the left arm. He had undergone multimodal imaging and was diagnosed as having Klippel-Trénaunay-Weber syndrome (KTWS). This is a rare congenital disease, defined by combinations of nevus flammeus, venous and lymphatic malformation, and hypertrophy of the affected limbs. Lower extremities are affected mostly. Conventional modalities for evaluating KTWS are ultrasonography, CT, MRI, lymphoscintigraphy, and angiography...

Malignant peripheral nerve sheath tumors (MPNSTs) are rare neuroectodermal tumors resulting from the malignant transformation of benign plexiform neurofibromas. The sporadic form of these tumors is rare than familial variants (seen in neurofibromatosis Type 1) and making the diagnosis difficult. We are presenting a case of 40--year-old female with the complaint of progressive swelling of lower limb with initial suspicion of lymphedema and underwent lymphoscintigraphy, magnetic resonance imaging, and finally fluorine-18-2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography scans were done to rule out mitotic etiology and extent of the disease...

This thesis is based on 10 original articles, of which 3 were previously included in the PhD thesis "Staging of women with breast cancer after introduction of sentinel node guided axillary dissection". In the PhD thesis is was shown that the introduction of sentinel lymph node dissection (SLND) in the treatment of breast cancer in Denmark has resulted in an increased identification of patients with micrometastases or isolated tumor cells (ITC) in the lymph nodes. Not all these small metastases are likely to disseminate to non-sentinel nodes...

BACKGROUND: Although genital lymphedema is a challenging disease, its mechanism is unclear. The aim of this study was to identify the lymphatic flow in genital lymphedema and establish a suitable examination for genital lymphedema. METHODS: We injected phytic acid or albumin labeled with (99m)Tc at the bilateral first web spaces of the feet of 47 patients for lymphoscintigraphy. For indocyanine green (ICG) lymphography, we injected ICG into the first web spaces of both feet and other points if necessary...

BACKGROUND: The National Comprehensive Cancer Network guidelines for Merkel cell carcinoma recommend performance of the sentinel lymph node biopsy in all patients with clinically negative nodal disease for staging and treatment. Nevertheless, sentinel lymph node biopsy in the periocular region is debated as tumors are typically smaller and lymphatic variability can make performance procedurally problematic. CASE PRESENTATION: We present a case of a Caucasian patient in their seventies who presented with a 1...

INTRODUCTION: Common protocols for the detection of sentinel lymph nodes in early breast cancer often include the injection of the tracer 1 day before surgery. In order to detect enough activity on the day of surgery, the applied activity in many protocols is as high as several hundred MBq. So far, very few protocols with an activity below 20 MBq have been reported. We developed an ultralow-dose 1-day protocol with a mean activity lower than 20 MBq in order to reduce radiation exposure for patients and staff...

BACKGROUND: The prognostic significance of multiple draining basins is controversial in melanoma because analyses have not adequately controlled for standard prognostic variables. We hypothesized that an analysis based on prognostically matched pairs of patients with multiple versus single drainage basins would clarify any independent role of basin number. STUDY DESIGN: We identified patients in our 40-year prospective database, who underwent preoperative lymphoscintigraphy, intraoperative sentinel node biopsy and wide local excision for cutaneous melanoma...

Recent advances in mesenteric science have demonstrated that the mesentery is a continuous structure with a 'watershed' area at the mesenteric apex between the right colon and terminal ileum, where lymphatic flow can proceed either proximally or distally. With this new understanding of the anatomy, functional features are emerging, which can have an impact on surgical management. Fluorescence lymphangiography or lymphoscintigraphy with indocyanine green allows real-time visualization of lymphatic channels, which highlights sentinel lymph nodes and may facilitate identification of the ideal margins for mesenteric lymphadenectomy during bowel resection for colon cancer...

Lymphedema is the chronic enlargement of tissue due to inadequate lymphatic function. Diagnosis is made by history and physical examination and confirmed with lymphoscintigraphy. The purpose of this study was to assess the accuracy of lymphoscintigraphy for the diagnosis of lymphedema and to determine characteristics of patients with false-negative tests. METHODS: Individuals referred to our lymphedema program with "lymphedema" between 2009 and 2016 were analyzed. Subjects were assessed by history, physical examination, and lymphoscintigraphy...

BACKGROUND: Intraoperative sentinel node (SN) identification in patients with head-and-neck malignancies can be challenging due to unexpected drainage patterns and anatomical complexity. Here, intraoperative navigation-based guidance technologies may provide outcome. In this study, gamma camera-based freehandSPECT was evaluated in combination with the hybrid tracer ICG-(99m)Tc-nanocolloid. MATERIALS AND METHODS: Eight patients with melanoma located in the head-and-neck area were included...

The integration of medical imaging technologies into diagnostic and therapeutic approaches can provide a preoperative insight into both anatomical (e.g. using computed tomography (CT), magnetic resonance (MR) imaging, or ultrasound (US)), as well as functional aspects (e.g. using single photon emission computed tomography (SPECT), positron emission tomography (PET), lymphoscintigraphy, or optical imaging). Moreover, some imaging modalities are also used in an interventional setting (e.g. CT, US, gamma or optical imaging) where they provide the surgeon with real-time information during the procedure...

Background -Cardiac transplantation is an excellent treatment for end-stage heart disease. However, rejection of the donor graft, particularly by chronic rejection leading to cardiac allograft vasculopathy, remains a major cause of graft loss. The lymphatic system plays a crucial role in the alloimmune response, facilitating trafficking of antigen presenting cells (APCs) to draining lymph nodes (dLN). The encounter of APCs with T lymphocytes in secondary lymphoid organs is essential for the initiation of alloimmunity...

BACKGROUND: Patients with secondary lower extremity lymphedema (LEL) often develop suprapubic lymphedema. We developed a novel surgical method of shaping the lower abdomen and debulking suprapubic lymphedema with simultaneous reconstruction of lymphatic flow in case of LEL. METHODS: A skin incision in a fleur-de-lis pattern was performed for horizontal and vertical abdominal skin and fat resection. A caudal-based isosceles triangular flap was created on the central suprapubic region to reduce wound tension at the intersection of the horizontal and vertical incisions...
