Clinical features and endovascular management of iliac artery fibromuscular dysplasia.
To identify the spectrum of clinical presentation of iliac artery fibromuscular dysplasia (FMD) and to evaluate the outcomes of endovascular management of iliac artery FMD for claudication. ⋯ Iliac artery FMD that is amenable to endovascular treatment may be found incidentally or may manifest with disabling claudication.

CT fluoroscopy-guided percutaneous fiducial marker placement for CyberKnife stereotactic radiosurgery: technical results and complications in 222 consecutive procedures.
To evaluate technical outcome and safety of computed tomographic (CT) fluoroscopy-guided percutaneous fiducial marker placement before CyberKnife stereotactic radiosurgery. ⋯ CT fluoroscopy-guided percutaneous fiducial marker placement can be performed with high technical success under local anesthesia in various anatomic regions. Although self-limiting in most cases, pneumothorax and pulmonary hemorrhage are frequently observed during fiducial marker implantation into lung tumors.

Case ReportsEndovascular balloon-assisted embolization of high-flow peripheral vascular lesions using dual-lumen coaxial balloon microcatheter and Onyx: initial experience.
Balloon-assisted embolization performed by delivering Onyx ethylene vinyl alcohol copolymer through a dual-lumen coaxial balloon microcatheter is a new technique for the management of peripheral vascular lesions. This technique does not require an initial reflux of Onyx to form around the tip of the microcatheter before antegrade flow of Onyx can commence. In a series of four patients who were treated with the use of this technique, the absence of significant reflux of Onyx was noted, as were excellent navigability and easy retrieval of the balloon microcatheter. However, in one patient, there was inadvertent adverse embolization of a digital artery, which was not caused by reflux of Onyx but could still be related to balloon inflation.

Externalization of tunneled hemodialysis catheter in patients with tunnel or exit-site infections and limited access options.
To evaluate the viability and effectiveness of temporary externalization of a tunneled hemodialysis (HD) catheter in catheter-dependent HD patients presenting with catheter-related tunnel or exit-site infection, documented central venous stenosis, and limited alternative venous access. ⋯ Temporary dialysis catheter externalization appears both technically feasible and effective for the treatment of exit-site and tunnel infections, while allowing preservation of the venous access site in catheter-dependent HD patients with central venous stenosis and limited alternative venous access.
