Case ReportsPainful pathologic fracture of the humerus: percutaneous osteoplasty with bone marrow nails under hybrid computed tomography and fluoroscopic guidance.
A case of a 75-year-old patient with a painful pathologic humeral shaft fracture, with unacceptably high surgical risk and unsatisfactory analgesia is reported. In this case, impaired arm function and persistent pain with conservative management resulted in a poor quality of life. ⋯ Because of potential cement leakage, inadequate fracture reduction, the site of the fracture, and the mobility of the joints in that area, image-guided percutaneous delivery of metallic bone marrow nails implanted together with polymethyl methacrylate (PMMA) osteoplasty was performed. This procedure achieved humeral shaft stabilization, bone fragment alignment, fracture reduction, and pain relief.

Discriminant analysis of native thoracic aortic curvature: risk prediction for endoleak formation after thoracic endovascular aortic repair.
To determine the association of native thoracic aortic curvature measured from computed tomographic (CT) angiography categorized by discriminant analysis with the development of endoleaks after thoracic endovascular aortic repair (EVAR). ⋯ Discriminant analysis of native thoracic aortic morphology measured from CT angiography is a useful tool to predict the risk of endoleak formation after thoracic EVAR and should be implemented during treatment planning and follow-up.

Photothermal ablation with the excimer laser sheath technique for embedded inferior vena cava filter removal: initial results from a prospective study.
To evaluate the safety and effectiveness of the excimer laser sheath technique for removing embedded inferior vena cava (IVC) filters. ⋯ The laser-assisted sheath technique appears to be a safe and effective tool for retrieving embedded IVC filters, including permanent types, with implantation ranging from months to > 18 years.

Comparative StudyOptional vena cava filter use in the elderly population.
To review utility, safety, and efficacy of optional inferior vena cava (IVC) filters in patients 65 years or older at a single institution over a 6-year period. ⋯ Optional filters are safe and effective in patients aged 65 years or older. Age alone is a poor predictor of a clinical opportunity to remove a filter. With appropriate patient selection and aggressive follow-up, retrieval rates comparable with those in younger populations can be achieved.

Retrievability and device-related complications of the G2 filter: a retrospective study of 139 filter retrievals.
To evaluate the retrievability and safety of the G2 filter. ⋯ The majority of G2 filters can be removed without difficulty. The most common factor affecting retrieval was severe tilting. The indwelling time had no impact on retrieval. G2 filter-related complications were frequent but most, including fractures, were clinically insignificant.
