Multispectral Real-time Fluorescence Imaging for Intraoperative Detection of the Sentinel Lymph Node in Gynecologic Oncology
1Department of Surgery, Division of Surgical Oncology, University Medical Center Groningen, 2Helmholtz Zentrum, Technical University Munich, 3Department of Obstetrics and Gynaecology, University Medical Center Groningen
Fluorescence imaging is a promising innovative modality for image-guided surgery in surgical oncology. In this video we describe the technical procedure for detection of the sentinel lymph node using fluorescence imaging as showcased in gynecologic oncologicy. A multispectral fluorescence camera system, together with the fluorescent agent indocyanine green, is applied.

A New Single Chamber Implantable Defibrillator with Atrial Sensing: A Practical Demonstration of Sensing and Ease of Implantation
Heart Center Rostock, University Hospital of Rostock, Germany
Dual-chamber implantable cardioverter-defibrillators (ICDs) may improve detection of atrial fibrillation as well as differentiation of tachycardias. However, this advantage is undermined by complications associated with the second electrode, which is required in conventional dual chamber devices. Therefore, BIOTRONIK has developed a new electrode called the LinoxSMART S DX that, when used in conjunction with the Lumax DX ICD, offers dual-chamber detection without the risks associated with the second electrode.

Preparation and Using Phantom Lesions to Practice Fine Needle Aspiration Biopsies
1Department of Pathology, University of Wisconsin - Milwaukee, 2BioInnovation LLC
Practicing of fine needle aspiration biopsies (FNAB) by trainees is relatively challenging, due to the lack of an easily available, appropriate lesion. Preparation of an AV phantom lesion for practicing the FNAB procedure and mastering proficiency is relatively easy.

Microsurgical Venous Pouch Arterial-Bifurcation Aneurysms in the Rabbit Model: Technical Aspects
1Department of Neurosurgery, Hospital Rudolfstiftung, 2Department of Neurosurgery, Kantonsspital Aarau, 3Cerebrovascular Research Group, Department of Biomedical Research, Medical University of Vienna, 4Cerebrovascular Research Group, Department of Intensive Care Medicine, University of Berne, 5Centre for Anatomy and Cell Biology, Department of Systematic Anatomy, Medical University of Vienna, 6Department of Neurology, Paracelsus University Salzburg
An optimized technique for the microsurgical creation of arterial bifurcation aneurysms mimicking bifurcation human cerebral aneurysms is described. A venous pouch is sutured into an artificially created true bifurcation of both common carotid arteries. Facilitated microsurgical techniques and aggressive postoperative anticoagulation and analgesia lead to minimized morbidity rates and high aneurysm patency rates.

Cerenkov Luminescence Imaging (CLI) for Cancer Therapy Monitoring
Use of Cerenkov Luminescence Imaging (CLI) for monitoring preclinical cancer treatment is described here. This method takes advantage of Cerenkov Radiation (CR) and optical imaging (OI) to visualize radiolabeled probes and thus provides an alternative to PET in preclinical therapeutic monitoring and drug screening.
