percutaneous fluoroscopic removal of a knotted swan ganz Catheter in a patient with a persistent left sided superior vena cava
Journal of Medical Imaging and Radiation Oncology, 2007Co-Authors: Dinesh Ranatunga, M G Richardson, Duncan Mark BrooksAbstract:Knotting of intravascular Catheters is an uncommon but a well-recognized occurrence. The Swan-Ganz Catheter (SGC) is the one that knots most commonly. A case of a knotted SGC is described in a patient with a persistent left-sided superior vena cava, and we propose that the presence of a left-sided superior vena cava is a risk factor for knot formation not previously reported. We review the published work on the risk factors for knot formation and on the techniques used to remove knotted SGC. We describe a technique using a gooseneck snare and Omni Flush Catheter (Angiodynamics, Queensbury, NY, USA) to loosen and untie a knotted SGC.

The Journal of Thoracic and Cardiovascular Surgery / Feasibility of profound hypothermia as part of extracorporeal life support in a pig model
Elsevier, 2017Co-Authors: Sterz Fritz, Weiser Christoph, Weihs Wolfgang, Holzer Michael, Testori Christoph, Kramer Anne-margarethe, Kment Christoph, Stoiber Martin, Poppe Michael, Wallmüller ChristianAbstract:Objective To investigate the feasibility of a refined aortic Flush Catheter and pump system to induce emergency preservation and resuscitation before extracorporeal cardiopulmonary resuscitation in a normovolemic cardiac arrest swine model simulating near real size/weight conditions of adults. Methods In this feasibility study, 8 female Large White breed pigs weighing 70 to 80 kg underwent ventricular fibrillation cardiac arrest for 15 minutes, followed by 4C aortic Flush (150 mL/kg for the brain; 50 mL/kg for the spine) via a new hardware ensued by resuscitation with extracorporeal cardiopulmonary resuscitation. Results Brain temperature was lowered from 39.9C (interquartile range [IQR] 39.6-40.3) to 24.0C (IQR 20.8-28.9) in 12 minutes (IQR 11-16) with a median cooling rate of 1.3C (IQR 0.7-1.6) per minute. A median of 776 mL (IQR 673-840) per minute with a median pump pressure of 1487 mm Hg (IQR 1324-1545) were pumped to the brain. Conclusions With the new hardware, we were able to cool the brain within a few minutes in a large pig cardiac arrest model. The exact position; the design, diameter, and length of the Flush Catheter; and the brain perfusion pressure seem to be critical to effectively reduce brain temperature. Redistribution of peripheral blood could lead to sterile inflammation again and might be avoided.(VLID)485634
