A Compact Measurement Setup for Material Characterization in W-Band Based on Dielectric Waveguides.

In this contribution, we present a measurement system for material characterization in the millimeter-wave range that requires extremely small amounts of sample material. With the help of a dielectric waveguide, it is possible to measure the complete S-parameters with only one port. Fundamentals regarding dielectric waveguides and algorithms are explained, which form the basis of the measurement system.

Field Representation Microwave Thermography Utilizing Lossy Microwave Design Materials.

In this contribution, we are investigating a technique for the representation of electromagnetic fields by recording their thermal footprints on an indicator material using a thermal camera. Fundamentals regarding the interaction of electromagnetic heating, thermodynamics, and fluid dynamics are derived which allow for a precise design of the field illustration method. The synthesis and description of high-loss dielectric materials is discussed and a technique for a simple estimation of the broadband material's imaginary permittivity part is introduced.

Challenging the limits in pancreatic surgery: A case report.

Introduction: Today, pancreatic surgery can be performed with low mortality and tolerable morbidity in specialized centers. Nevertheless, due to its anatomical localization and proximity to important vascular structures, surgical resection of the pancreas remains challenging in many cases.

Presentation Of Case: Here, we present the case of a young woman who presented in our department with abdominal pain and a tumor mass located at the pancreatic head.

Results from a First-in-Human Trial of a Novel Vascular Sealant.

Background: Suture hole bleeding from synthetic grafts presents a hemostatic challenge. The designs of many vascular sealants are not optimal (non-adherence to wet surfaces, excessive swelling, inflexible). PreveLeak™ (formerly ArterX ((®)) ) is a polyaldehyde-bovine serum albumin-based sealant whose efficacy, safety, and performance were evaluated in this first-in-human study.

["EVAR First" also in "Fit-for-Open-Repair" Patients? - 'CON' Statement].

Our own long-term results and the numerous published data from the literature indicate that after open surgery or endovascular treatment, there is no significant difference with regard to morbidity and lethality in the early and long-term postoperative outcome of patients with low comorbidity ("low-risk" patients or patients "fit for open repair"). The advantage of endovascular aneurysmatic "repair" (EVAR) is revealed only in risk patients resulting in the fact that patient selection has a decisive role for the prognosis. Typical EVAR-associated complications such as late ruptures and secondary conversions, the re-intervention rate post-EVAR between 20 and 30 % as well as the appropriate training of young vascular surgeons favour a not too stringent limitation, i.
