Emergency Reinforcement Of Cracked Paracorporeal Blood Pumps
ASAIO journal (American Society for Artificial Internal Organs : 1992)(2004)
Abstract
In a patient with biventricular paracorporeal cardiac support, severe cracks in the outer pump housing occurred for unknown reasons (possibly because of the application of solvent). Pump replacement was considered but estimated to be a very high risk for this particular patient. Therefore, it was decided to glue the ventricles. Gluing was done after pilot tests in a two stage procedure: first, with a special glue that hardens under exposure to ultraviolet light and then with a two component low exothermic epoxy resin. The procedure resulted in very satisfying stability for the remainder of the bridging period, and the patient could be transplanted successfully 59 days after the event. It is concluded that a carefully selected gluing procedure (caveats: with previously tested glue, a validated procedure, and as a last resort only) may bring less risk in such rare cases of pump cracks than a pump exchange.
