The role of postintervention pullback pressure gradient in percutaneous transluminal angioplasty for central vein stenosis in dialysis patients.

Purpose: The severity of residual stenosis (RS) sometimes cannot be accurately measured by angiography during central vein intervention. This study evaluated the role of pullback pressure measurement during central vein stenosis (CVS) intervention.

Methods: A retrospective review enrolled 94 consecutive dialysis patients who underwent CVS interventions but not stenting procedures.

Feasibility and safety of a transradial approach in intervention for chronic total occlusion of coronary arteries: a single-center experience.

Background: The transradial approach for cardiac catheterization has become popular; however, its application in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) has rarely been reported. This study examines the feasibility and safety of this approach for performing PCI for CTO lesions.

Method: We retrospectively evaluated 419 consecutive patients who underwent PCI for CTO lesions between February 1998 and December 2003 in our hospital; a transradial artery approach was used in 400 patients and a transfemoral artery approach in 19.

Bilateral cardiac catheterizations: the safety and feasibility of a superficial forearm venous and transradial arterial approach.

The transradial approach for left heart catheterization has become increasingly popular recently because of its clinical benefits. We examined the safety and feasibility of a transforearm approach for bilateral cardiac catheterizations, using the radial artery and a superficial forearm vein (the cephalic, basilic, or median antecubital vein). Between August 2002 and October 2003, 296 right heart catheterizations were performed in our hospital.

The safety and feasibility of transradial cutting balloon angioplasty: immediate results, benefits, and limitations.

Cutting balloon angioplasty can reduce the restenosis rate more than conventional balloon angioplasty, but is traditionally performed through a femoral artery. However, it is not clear how useful a transradial approach would be for cutting balloon angioplasty. This study was conducted to examine the safety, feasibility, and limitations of transradial as opposed to transfemoral cutting balloon angioplasty.
