Retrieval of embolized central venous catheters by a Dormia ureteral stone dislodger with straight filiform tip.

Two cases are presented in which a Dormia ureteral stone dislodger with straight filiform tip was used to retrieve broken central venous pressure catheters from the right side of the heart and vena cavae. It should be emphasized that this particular model is more easily passed into the vascular system and more easily manipulated within the vascular system. The delicate filiform tip also contributes to greater safety. It should also be emphasized that entrapment of the proximal tip of a fractured central venous pressure catheter is most ideal prior to extraction.
