Novel wrapping technique with insertion of fat tissue for hemostasis in aortic surgery

The standard techniques and prosthetic materials for graft replacement in aortic surgery have been dramatically improved. However, persistent oozing and bleeding during aortic surgery sometimes occur and lead to life-threatening problems because of severe coagulopathy, which results from induced hypothermia, long cardiopulmonary bypass time, or fragile aortic walls by acute aortic dissection. Although various techniques and devices for reduction of bleeding have been already documented, these techniques are not always perfect and are sometimes complex. A new wrapping technique with insertion of fat tissue, as described in this report, is simple and provides a perfect hemostasis.
