Comparative StudyTortuous iliac systems--a significant burden to conventional cannulation in the visceral segment: is there a role for robotic catheter technology?
To attempt to quantify the effect of varying degrees of iliac tortuosity on maneuverability and "torquability" of endovascular catheters in the visceral segment, comparing conventional and robotic cannulation techniques. ⋯ In cases of moderate to severe iliac tortuosity, conventional catheter manipulation and control becomes an issue. The improvement in positional control and predictability seen with advanced catheter designs may be amplified in cases of severe iliac tortuosity.

Cementoplasty of metastases of the proximal femur: is it a safe palliative option?
Percutaneous cementoplasty has proved very effective for the palliation of pain from bone metastases. However, several studies argue that it should be contraindicated for metastases that are located in the proximal femur because of inadequate bone consolidation. The aim of this study was to evaluate the risk factors for fracture despite performing cementoplasty for metastases of the proximal femur. ⋯ Percutaneous cementoplasty can be considered for patients with metastases of the proximal femur under certain conditions: cortical involvement less than 30 mm and no history of a fracture of the lesser trochanter. Otherwise, the risk of fracture is too high, and cementoplasty is contraindicated.

CT fluoroscopy-guided percutaneous osteoplasty for the treatment of osteolytic lung cancer bone metastases to the spine and pelvis.
To retrospectively assess the results of computed tomographic (CT) fluoroscopy-guided percutaneous osteoplasty (PO) of osteolytic lung cancer bone metastases, focusing on pain reduction, improved quality of life, and patient mobility. ⋯ PO was shown to be a highly effective and safe palliative therapy to reduce pain and improve quality of life and patient mobility, not only in vertebral metastases, but also in pelvic, iliac, and femoral metastases.
