Many researchers have reported that the sentinel node (SN) theory has been established for lung cancer. However, sentinel node navigation surgery (SNNS) has not yet become a routine medical procedure in lung cancer surgery. SN identification is important for efficient retrieval of micrometastases. Methods for identifying SNs include the dye method and the radioisotope (RI) method, but methods such as the indocyanine green (ICG) method, computed tomographic lymphography (CTLG), and the magnetic method are also being studied...

Recent introduction of multidetector-row computed tomography(MDCT) with more than 64 scanners enabled high-speed scanning in wide range of the body. Electrocardiogram (ECG) gated scanning and 4-dimensional imaging provides precise evaluation of cardiac and vascular diseases. Fine vascular structures such as the artery of Adamkiewicz can be visualized due to improved spatial and temporal resolution of CT and magnetic resonance imaging(MRI). Interventional radiology also plays important roles in combination with surgical treatment...

BACKGROUND: Lymphaticovenular anastomosis (LVA) is generally an effective procedure for breast cancer treatment-related upper extremity lymphedema (UEL). Clinical improvement is, however, limited by the degree of sclerosis of the lymphatic vessels. We have developed a method by which we use dynamic ultrasonography to depict vessels through which lymph can be propelled into the LVA under the power of the patient's natural hand movements. METHODS: We assessed the dynamic-LVA method by comparing clinical details of 15 cases of breast cancer treatment-related lymphedema treated by dynamic LVA and 15 corresponding cases treated by conventional LVA...

BACKGROUND: Evaluation of intermittent pneumatic compression (IPC) in lymphedema is classically based on measurements of circumferences and volume of the edematous limb. However, although important, it provides only a general information without insight into what proceeds under the skin with respect to hydromechanical and structural changes. AIM AND METHODS: We present the multimodal evaluation of the effectiveness of IPC device in limb edema by measuring tissue stiffness, fluid pressure, and flow volume, and lymphoscintigraphic and near-infrared fluorescence (NIRF) indocyanine green (ICG) lymphography imaging of edema fluid movement, before and after one 45-60 minute compression cycle in over 50 patients with lymphedema stage II and III...

Due to its accessible position and tissue heterogeneity, the eye is ideally suited for studying the lymphatic system. As early as the 19th century, questions about the origin and function of this system were discussed. For example, whether Schlemm's canal, which is of particular importance in the pathogenesis of glaucoma, is a lymphatic vessel, or does this vascular system begin with finger-shaped protuberances? Despite the discovery of lymphatic endothelial molecules and the use of molecular imaging technologies, these questions are still discussed controversially today...

BACKGROUND: Supermicrosurgical lymphaticovenular anastomosis (LVA) is becoming a useful treatment option for progressive lower extremity lymphedema (LEL) with its minimal invasiveness. Finding lymphatic vessel is a minimum requirement for LVA surgery, but no study has reported comprehensive analysis on factors associated with lymphatic vessel detection (LVD). METHODS: One hundred thirty-four female secondary LEL patients who underwent indocyanine green (ICG) lymphography and LVA without past history of lymphedema surgery were included...

The detection of distant metastases at the initial diagnosis of prostate cancer (PCa) establishes the treatment approach and has a prognostic value, nevertheless it is not well established. Since proposed staging approaches often contradict each other, we aimed to compare the current imaging techniques for staging of advanced PCa, including future applications of the most innovative methods. Conventional imaging techniques, including computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) have been employed for metastatic staging (both N and M staging) of men with high-risk PCa, but surgical pelvic dissection remains the gold standard for N staging...

BACKGROUND: Early detection of lymphedema gives an opportunity for effective and successful treatment of lymphedema. However, the current diagnosis methods, except the bioimpedance analysis, perometry, and indocyanine green lymphography, have limitations in detecting early stage lymphedema. Sonoelastography is a diagnostic ultrasound technique that provides an opportunity to estimate soft tissue stiffness. Shear wave elastography (SWE) is a brand new elastography technique. Unlike strain elastography, this method is conducted automatically, that is, independently of user's manual tissue compression...

BACKGROUND AND OBJECTIVES: Lymphedema is caused by insufficient lymphatic drainage leading to abnormal accumulation of interstitial fluid within soft tissues. Lympho-venous anastomosis (LVA), as a surgical option for selected patients, is widely applied. Through preoperative localization of functional lymphatics with indocyanine green, real time visualization of functioning lymphatic vessels is possible. This examination is time consuming and operator dependant and is not suitable to differentiate the ratio of fat hypertrophy to liquid edema...

Surgical laparoscopic procedures in the retroperitoneal and supramesocolic spaces are increasingly frequent. There is a high risk of iatrogenic intraoperative injury of the retroperitoneal lymphatic structures during these procedures. A precise understanding of the anatomy of the thoracic duct (TD) and the cisterna chyli (CC) is essential for safe surgical procedures in this area. However, routine imaging procedures rarely and often incorrectly visualize the CC. The objective of this study was to evaluate the feasibility of a retrograde injection of the TD to fill the CC with a contrast agent in 16 human cadavers...

BACKGROUND:  Indocyanine green (ICG) fluorescence lymphography (ICGLG) that can visualize the lymphatic vessel and its flow noninvasively and dynamically was developed in 2007. It is frequently used to observe the function and pathway of the lymphatic vessels. ICGLG is simple and easy to perform, and it is useful for understanding the condition of the lymphatic system in real time. However, its protocol is not standardized. In addition, the lymphatic flow is enhanced by an exercise load such as walking...

BACKGROUND: The lymph system plays important roles in maintaining fluid balances, the immune system, and lipid metabolism. After tissue replantation or transfer, some cases suffer long-lasting edema or lymphedema caused by interruption of main lymph flows; however, this mechanism has yet to be clarified. METHODS: The medical charts of 38 patients who underwent indocyanine green lymphography after tissue replantation or free flap transfer were reviewed to obtain data regarding clinical demographics, intraoperative findings, and postoperative indocyanine green lymphographic findings...

BACKGROUND: Vascularized lymph node transfer is a promising surgical treatment for lymphedema. This study investigated the effect of ischemia on the lymphatic drainage efficiency of vascularized lymph node flaps and the critical ischemia time of lymph nodes. METHODS: Twenty-four lymph nodes containing groin flaps in 12 Sprague-Dawley rats were dissected. Clamping of the vascular pedicle was performed for 0, 1, 3, 5, 6, or 7 hours; then, each was allowed to reperfuse by means of the vascular pedicle for 1 hour...

Background: The morphologic and histologic behavior of lymphatic vessels in lymphedema has not been well analyzed using laboratory animals. The purpose of the present study was to elucidate the regeneration process of lymphatic vessels after acute lymphedema in a rat model. Methods: The acute lymphedema was induced by an amputation and a replantation surgery on a rat hind limb. Recovery of lymphatic flow was traced using fluorescent lymphography with dye injection...
