Background and Aim: Swan-Ganz catheterization is an important technique for
monitoring perioperative and postoperative cardiac pressures during open h
eart surgery. However, although a rare condition, resistance may be encount
ered while removing the catheter postoperatively and its removal must be ac
complished through surgery. Methods: Between May 1988 and February 2000, we
observed Swan-Ganz catheter entrapment complications in 10 cases subjected
to open heart surgery. All the cases had valve replacement. Five cases wer
e male, while five were female. The Swan-Ganz catheter was retained in the
vena cava cannulation suture in four cases, in the right atriotomy in three
cases, in a left atriotomy suture in one case, and looped around the right
ventricular papillary muscle in one case. In the last case, it was looped
around chordae tendinea between the tricuspid valve conal papillary muscle
and septal leaflet. Although cardiopulmonary bypass equipment was prepared,
it was not utilized in any of the cases. The catheter was released and rem
oved by placing a pursestring suture on the vena cava cannulation site in f
our cases, by placing a matrix suture on the proximal and distal part of th
e left or right atria] suture line and a pursestring suture on the site of
the entrapment in four cases, and by digital palpation from the right atria
[ appendage in two cases. Results: All patients were taken to the intensive
care unit postoperatively and to the wards the next day without complicati
ons. Conclusions: When performing open heart surgery, the surgeon should no
t leave the Swan-Ganz catheter in the suture while closing the right or lef
t atriotomy or during venous cannulation. In addition, the catheter should
be moved after suturing to ensure that there is no entrapment.
