The use of an overlay autogenous tissue (OAT) patch to control intra-operative haemorrhage of the spleen.

Background: During major abdomino-pelvic surgery, there is a risk of severe haemorrhage. When routine measures at haemostasis fail, the overlay autogenous tissue (OAT) patch may be useful to control bleeding.
Case: We present a case report of the use of the use of an OAT patch to control haemorrhage of the spleen incurred during tertiary cytoreduction.
Conclusion: The OAT patch should be considered in situations where bleeding is unable to be controlled after routine measures have failed and in instances other than for vascular injury alone. This technique has implications for practice in a wide range of gynaecologic oncology surgery.
