Comparative StudyUltrahigh-pressure versus high-pressure angioplasty for treatment of venous anastomotic stenosis in hemodialysis grafts: is there a difference in patency?
Ultrahigh-pressure (UHP) balloon catheters were compared with high-pressure (HP) balloon catheters to determine if there was a difference in patency after percutaneous transluminal angioplasty (PTA) of venous anastomotic stenoses. ⋯ Routine use of UHP for PTA of venous anastomotic stenoses in synthetic hemodialysis grafts was not associated with any significant change in patency compared with routine HP balloon angioplasty.

Treatment of vertebral tumor with posterior wall defect using image-guided radiofrequency ablation combined with vertebroplasty: preliminary results in 12 patients.
To evaluate the safety and clinical benefit of vertebral tumor treatment by combined radiofrequency ablation (RFA) and vertebroplasty, for pain reduction in patients who are unable to benefit from noninvasive treatment methods. ⋯ RFA in combination with vertebroplasty for treating vertebral tumors with posterior wall defect appeared safe, and reduced pain substantially in patients who did not benefit from other noninvasive treatment methods.

Case ReportsPercutaneous osteoplasty with use of a cement-filled catheter for a pathologic fracture of the humerus.
Percutaneous osteoplasty has been used for pathologic fractures of long bones as an adjunct to orthopedic surgery. The present report describes a case of percutaneous osteoplasty with a cement-filled catheter and cement augmentation as the principal therapy to unite a painful pathologic fracture of the humerus. After the procedure, the patient experienced immediate pain relief and improved limb mobility. Percutaneous osteoplasty with this method holds promise as a treatment for pathologic fractures of the humerus that are not amenable to surgical repair.
