Swan-Ganz catheters are routinely used for monitoring of critically ill patients. These catheters can become knotted during the process of insertion, which can pose a challenge for removal.
A 63-year-old man underwent placement of a Swan-Ganz catheter, which was knotted and could not be removed. Ultimately, removal was achieved by tightening the knot in the Swan-Ganz catheter against the inlet of its sheath. The catheter and sheath were then pulled together out of the skin in a single motion.
Multiple methods have been described to remove such knotted catheters although no consensus exists.
TAKE-HOME MESSAGE: A knotted Swan-Ganz catheter can be safely removed by tightening the knot against the inlet of its sheath to reduce the knot size and then simply pulling the catheter and sheath together out of the skin.
Swan-Ganz导管常用于危重症患者的监测。这些导管在插入过程中可能会打结，这给拔除带来挑战。
一名63岁男性接受了Swan-Ganz导管置入，导管打结且无法拔除。最终，通过将Swan-Ganz导管上的结紧压在其鞘管入口处实现了拔除。然后将导管和鞘管一起一次性从皮肤中拔出。
尽管尚未达成共识，但已有多种方法用于拔除此类打结的导管。
对于打结的Swan-Ganz导管，可通过将结紧压在其鞘管入口处来减小结的大小，然后简单地将导管和鞘管一起从皮肤中拔出，从而安全地拔除。
