“…The knot was cut surgically and removed. The reason pulling on the catheter caused pain is not exactly known to the authors 5. However, they believe that it was due to traction or the displacement of mediastinal structures or the shifting or stretching of the superior vena cava.…”

SUMMARYWe describe here two more radial knots that could be unravelled by counter-clockwise rotation alone. We and others have previously described radial knots that occur when trying to engage the right coronary artery (RCA). Here, we show two knots that were unravelled purely by counter-clockwise rotation. One occurred during RCA catheterisation and the other occurred during left coronary angiography via the radial route. In one of the patients, severe pain occurred in the right shoulder. This occurred even though the artery was not in spasm. We were able to move the catheter. Therefore it is possible that pain combined with the ability to move the catheter may be a marker of an intravascular knot. BACKGROUND

“…Skinner and Burroughs5 also discussed the possible causes of pain during knots. They described a 38-year-old man admitted as far back as 1959 for a suspected pulmonary arteriovenous fistula.…”

“…If more than 10 cm distance of catheter is required from the right ventricle, or more than 50 cm length from the right internal jugular vein, then catheter looping or knotting should be suspected. When the patient complains of pain during withdrawal, one must always have a suspicion that the catheter has coiled around an intracardiac structure 10. Skinner et al described a patient who had pain during manipulation of a Cournand catheter.…”

Most case reports or series describe knots in the venous system such as knots of Swan-Ganz catheters, pacing wires or thermodilution catheters. Knots during radial angiography are relatively rare. Here we describe a simple method of unravelling a radial knot via the femoral route, together with a review of the literature on knots in the catherisation laboratory and the techniques to deal with them.
