Ultrasound-Guided vs Non-Ultrasound-Guided Angio-Seal Vascular Hemosasis After Endovascular Treatment for Peripheral Artery Disease: An Observational Study.

Ultrasound visualization of vascular closure devices during endovascular access closure leads to a significant decrease in overall and major post interventional access site complications. This non-invasive and often readily available imaging technique could therefore lead to an important decrease in morbidity and subsequent overall health care costs when added to the standard intervention protocol. With the increasing use of endovascular techniques to treat peripheral artery disease, the addition of ultrasound-techniques in closure of endovascular access sites could potentially have a large clinical impact, both on patient outcomes as well as financial outcomes.

Emergency embolization of a massive life-threatening placenta percreta bleeding following delivery by Cesarean section.

The rise in the number of Cesarean sections (CS) worldwide has increased the incidence of the placenta accreta spectrum disorders in the past years. About 5% of patients undergoing a CS develop placenta percreta. A 30-year-old woman, G2P1 with previous uncomplicated CS delivery had an elective CS delivery at 37w6d.

Solvation force and adsorption isotherm of a fluid mixture in nanopores of complex geometry based on fundamental measure theory.

A novel method based on the fundamental measure theory is developed to calculate the solvation force and adsorption isotherm of a Lennard-Jones fluid mixture in complex geometries. Fast Fourier transform and 3D-voxel discretization are used for accurately computing the confined fluid densities in a closed pore of arbitrary geometry. Given the fluid densities, the solvation force distribution at the solid surface can be calculated using a new formulation from either mechanical or thermodynamic approach.

Ultra-small superparamagnetic iron oxides for metastatic lymph node detection: back on the block.

In the past 15 years, encouraging clinical results for the detection of small lymph node metastases was obtained by the use of Combidex-enhanced MRI (CEM, also known as magnetic resonance lymphography). Withdrawal of the European Medicines Agency approval application by the manufacturer made it impossible for patients to benefit from this agent; a loss, especially for men with prostate cancer. Current conventional imaging techniques are not as accurate as CEM is, thus a surgical diagnostic exploration (extended lymph node dissection) is still the preferred technique to evaluate the lymph nodes, resulting in peri- and postoperative complications.
