The VAC system, as well as its modification, the V.A.C.®
Abdominal Dressing System, is a useful alternative technique
for the management of open abdomen. The advantage
of modifications B and C is the more uniform topic
negative pressure to the wound edges and the fascia of the
open abdomen. The encapsulated foam in the center of
the polyethylene sheet of the commercial available
V.A.C.® Abdominal Dressing System prevents the intraabdominal
shift of the sheet. This modification keeps
the device in position and secures the functionality of the
system. In most cases, it allows a primary closure of the
fascia thus preventing a formation of large ventral hernias
and diminishes additional risks during subsequent reconstructive
surgery of the abdominal wall. It seems that the
traction force of the negative pressure on the wall edges of
the open abdomen does not increase intraabdominal pressure.
The technique is easy to handle, is performed in short
time and can be mastered without difficulties.
