Intravascular air after fibrin sealing by spray gun in cardiovascular surgery

During an operation for an ascending aortic aneurysm with implantation of a
saphenous vein graft to the left coronary artery into a prosthesis, we
occasionally observed air bubbles in the graft after application of fibrin
glue to the anastomosis to control bleeding. In an experimental study in a
pig, a vascular prosthesis was anastomosed to the descending aorta. The
aorta and the prosthesis were transected and reanastomosed. Air bubbles
were collected in a glass flask placed at the end of the prosthesis. Fibrin
glue was applied with a spray catheter on all anastomoses at varying
distances and with different air pressures. Small amounts of air were
collected in the glass flask when an air pressure of 3 or 4 bar was used.
This study demonstrates that the use of fibrin glue in cardiovascular
surgery can introduce air into the vascular system with subsequent air
emboli as a possible side- effect.
