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.

Comparative StudyUS-guided placement and tip position confirmation for lower-extremity central venous access in neonates and infants with comparison versus conventional insertion.
To describe experience with the use of ultrasound (US)-guided placement and tip position confirmation for direct saphenous and single-incision tunneled femoral noncuffed central venous catheters (CVCs) placed in neonates and infants at the bedside. ⋯ US-guided placement and tip position confirmation of lower-extremity CVCs at bedside for critically ill neonates and infants is a safe and feasible method for central venous access, with similar complications and catheter outcomes in comparison with CVCs placed by using fluoroscopic guidance in the IR suite.

Direct translumbar inferior vena cava ports for long-term central venous access in patients with cancer.
To evaluate the indications, complications, and long-term results of translumbar port placements to the inferior vena cava for long-term central venous access in a single tertiary center. ⋯ Translumbar inferior vena cava port placement is a technically feasible and safe alternative method for long-term central venous access.

Efficacy and safety of portal vein embolization for two-stage hepatectomy in patients with colorectal liver metastasis.
To examine the efficacy and safety of portal vein embolization (PVE) when used during two-stage hepatectomy for bilobar colorectal liver metastases (CLM). ⋯ PVE effectively and safely induced a significant DH in the FLR during two-stage hepatectomy in patients with CLM.
