The following information was obtained through an article published on cardiovascular intervention and therapeutics 2021: percutaneous removal of a knotted swan-ganz catheter.A (b)(6) year-old man who had undergone aortic valve surgery one week previously became hemodynamically unstable in the intensive care unit.His physician decided to insert a swan-ganz catheter (sgc) (edwards lifesciences, (b)(6) ) without fluoroscopic guidance.The sgc was inserted via the right internal jugular vein and advanced into the right ventricle, but it could not be advanced into the pulmonary artery.After repeated attempts, the physician pulled back the sgc, but it could not be retrieved.An x-ray examination showed a knot formation in the sgc.A new 5-fr sheath was placed in the right internal jugular vein, and a 0.014 inch guidewire (cruise; asahi intecc, tokyo, japan) was passed through the center of the knot.A 6-mm balloon (rx-genity, kaneka, tokyo, japan) was inflated to expand the knot diameter; however, the knot was not completely untied.A 10 mm-diameter amplatz goose neck snare (medtronic, dublin, ireland) was then advanced to the distal end of the sgc along with the cruise wire.The tip of the sgc was grasped and pulled back, causing the untying of the knot and a successful removal of the sgc.
