Abdominal compartment syndrome as a consequence of rectus sheath hematoma.

Abdominal compartment syndrome is a well-documented entity arising from multiple and various causes. The rise of intra-abdominal pressure by the increase in volume of the peritoneal and retroperitoneal contents has been shown in the resuscitation and evaluation of surgical patients. However, the incidence of constriction of the abdomen causing intra-abdominal hypertension is unknown. Previously limited to burn eschar and externally applied devices (such as MAST trousers), external compression leading to abdominal compartment syndrome has been a limited entity. We report the first documented case of an expansive abdominal wall mass, a rectus sheath hematoma, leading to impending abdominal compartment syndrome.
