Catheter replacement of the needle in percutaneous arteriography; a new technique.

Comparison of percutaneous versus open surgical techniques for placement of peritoneal dialysis catheter in children: A randomized clinical trial

  Background: This research compares the outcomes of percutaneous technique and open surgical peritoneal dialysis catheter placement in children.   Methods: In this randomized controlled trial, between 2010 and 2011,a total of 35 pediatric uremic patients were enrolled and randomized into two study groups. Follow up data included duration of operation (minute), duration of hospitalization (days...

Coronary arteriography by the single catheter percutaneous femoral technique. Experience in 6,800 cases.

Transcatheter CT arterial portography and CT hepatic arteriography for liver tumor visualization during percutaneous ablation.

PURPOSE To evaluate the feasibility of combining transcatheter computed tomography (CT) arterial portography or transcatheter CT hepatic arteriography with percutaneous liver ablation for optimized and repeated tumor exposure. MATERIALS AND METHODS Study participants were 20 patients (13 men and 7 women; mean age, 59.4 y; range, 40-76 y) with unresectable liver-only malignancies--14 with colo...

Transcatheter Aortic Valve Replacement: A Review Article

Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...

Serial arteriography of the dog: a simplified technique.

SERIAL ARTERIOGRAPHY OF THE infradiaphragmatic arterial system of the dog is useful in many chronic experimental situations. There are disadvantages to repeated arterial cannulation to obtain such arteriograms. The small fragile arteries of the dog make Seldinger needle cathet.erization difficult. Direct, exposure of the artery may be utilized but it is time-consuming, and a new site of cannula...
