Retroperitoneal Hematoma, Christopher Mondie, Rebecca M. Rentea

Manuscripts, Articles, Book Chapters and Other Papers

Retroperitoneal hematoma is defined as bleeding into the retroperitoneal space. This clinical entity is often occult and under-recognized by clinicians and is a cause of significant morbidity and mortality. Often patients do not manifest clinically apparent signs and symptoms until a substantial amount of blood loss has occurred. It is not uncommon for patients to present in frank hemorrhagic shock due to an underlying retroperitoneal hematoma. The retroperitoneal space lies directly posterior to the peritoneal cavity. An organizational schema dividing the retroperitoneal space into three different “zones” is widely prevalent in the surgical literature. The central-medial zone (Zone I) falls …
