  • Title: Knotting and entanglement of multiple central venous catheters.
    Author: Graff J, Gong R, Byron R, Hassett JM.
    Journal: JPEN J Parenter Enteral Nutr; 1986; 10(3):319-21. PubMed ID: 3712723.
    Abstract:
    A 53-yr-old black male was admitted with peripheral vascular disease and septic shock. Appropriate cardiopulmonary resuscitation and operative intervention required the placement of multiple central venous lines. These included two subclavicular central venous pressure (CVP) catheters and one Swan-Ganz catheter (SGC). During manipulation of the SGC, it formed a knot with the two CVP catheters entangled in it. After consideration of the variety of strategies that could be employed, the CVP catheters were manually disengaged from the knot and the knot was surgically removed. The increasing frequency and multiple central angioaccess catheters will result in a finite increase in the nature and complexity of the clinical challenges. The insistence on the use of multiple single-channel catheters for separate therapeutic functions and the duration of stay of pulmonary catheters should be reconsidered.
