a 30-year-old female with end-stage renal disease was a candidate for dual lumen catheter placement. after catheter insertion, o2 saturation measurement of the aspirated blood from the catheter was similar to that of arterial blood. they referred the patient to our hospital after 48 hours. diagnostic procedures revealed that the tip of the catheter had entered the pleural cavity. catheter remov...

BACKGROUND N-butyl 2-cyanoacrylate (NBCA) remains the standard embolic agent for spinal dural arteriovenous fistula (SDAVF) treatment. Treatment of SDAVF with ethylene-vinyl alcohol copolymer (Onyx, ev3-Covidien, Irvine CA, USA) is currently not well established. Although several cases have reported the use of Onyx to embolize an intracranial dural arteriovenous fistula using a dual-lumen micro...

INTRODUCTION Small intravascular volume, pathophysiological hemorheology, and/or low cardiac output [CO] are assumed to reduce available blood flow rates via common dual-lumen catheters (except for those with a right atrium catheter tip position) in the critically ill patient. We performed an experimental animal study to verify these assumptions. METHODS Anesthetized, ventilated pigs (35 to 5...

BACKGROUND AND PURPOSE Liquid embolic agents are increasingly used to treat vascular malformations. We sought to assess embolization with these agents by using a dual-lumen balloon catheter in an experimental setting. MATERIALS AND METHODS Eighteen injections of liquid embolic agents were performed in the rete mirabile of swine. We used 3 methods to control liquid embolic agent reflux: 1) dua...

Introduction: Percutaneously inserted double-lumen central venous hemodialysis catheters provide the nephrologist with an excellent temporary access for an immediate hemodialysis treatment and preserve the peripheral veins for the future creation of a permanent arteriovenous vascular access. Unfortunately catheterrelated infections are usually common. In this study, the impact of intra luminal ...

Extracorporeal membrane oxygenation (ECMO) is a therapeutic option used increasingly in the treatment of severe acute respiratory distress syndrome (ARDS). Choosing an adequate cannula type and insertion site can be a challenge. The insertion of a bi-caval dual lumen (Avalon®) catheter in the superior vena cava instead of two venous single-lumen catheters facilitates mobilisation and physiother...

To the Editor: With great interest we read the article by Cooper et al (1), published in a recent issue of Critical Care Medicine. In this article, frequent deep vein thrombosis after extracorporeal membrane oxygenation (ECMO), especially in patients with dual-lumen catheters, is reported. Neither Cooper et al nor Shafii et al (2) reported any thromboembolic event related to post-ECMO thrombosi...
