Pulmonary artery catheter complications: report on a case of a knot accident and literature review

Complicações do cateter de artéria pulmonar: relato de caso de formação de nó verdadeiro revisão da literatura

A particular event concerning a Swan-Ganz catheter complication is reported. A 41-year-old woman was admitted at the emergency room of our hospital with massive gastrointestinal bleeding. A total gastrectomy was performed. During the postoperative period in the intensive care unit , the patient maintained hemodynamic instability. Invasive hemodynamic monitoring with a pulmonary artery catheter was then indicated. During the maneuvers to insert the catheter, a true knot formation was identified at the level of the superior vena cava. Several maneuvers by radiological endovascular invasive techniques allowed removal of the catheter. The authors describe the details of this procedure and provide comments regarding the various techniques that were employed in overcoming this event. A comprehensive review of evidence regarding the benefits and risks of pulmonary artery catheterization was performed. The consensus statement regarding the indications, utilization, and management of the pulmonary artery catheterization that were issued by a consensus conference held in 1996 are also discussed in detail.
