Objective: Ultrasound-guided percutaneous vascular access for endovascular procedures is well established in surgical practice. Despite this, rates of complications from venous and arterial access procedures remain a significant cause of morbidity. We hypothesized that the use of a new technique of vascular access using an ultrasound with a novel needle-guidance positioning system (GPS) would lead to improved success rates of vascular puncture for both in-plane and out-of-plane techniques compared with traditional ultrasound.

Introduction: Purpose of this phantom study was to compare the accuracy of needle placement using a multi-axis, C-arm-based, flat-panel, cone-beam computed tomography system (CBCT guidance) with that under multi-detector computed tomography guidance (MDCT guidance).
Materials And Methods: In an abdominal phantom, eight lesions (six lesions in the liver and two in the renal pelvises, respectively) were each punctured in-plane and off-plane with a 20G needle under CBCT and MDCT guidance. Access paths were initially defined and reproduced identically on the two systems. Read More

Purpose: The application of ultrasound-guidance for peripheral venous access is gaining popularity. It is possible to produce a short axis or a long axis sonographic view of the target vessel and apply an out-of-plane or in-plane needle tip approach. Our aim was to present the dynamic needle tip positioning technique and to estimate which approach is the most accurate for inserting the needle tip into the center of the target vessel. Read More

Objective: The purpose of this phantom study was to assess a new real time electromagnetically-guided navigation system and compare it to standard computed tomography (CT) guidance.
Material And Methods: A prospective, randomized, comparative study was carried out over a two-day period. Operators without prior experience on the new navigation system sequentially attempted to puncture two 6 mm-diameter targets (one attempt for each target) with out-of-plane trajectories using both the standard CT-guided method and the new navigation station (NAV method).
