Signs and symptoms may include:
Retroperitoneal bleeds are most often caused by major trauma, such as from a traffic collisions or a fall.[3] Less common non-traumatic causes including:
Retroperitoneal bleeds may also be iatrogenic, caused accidentally during medical procedures. Such procedures include cannulating the femoral artery for cardiac catheterization or for interventional radiology,[3][5] and the administration of a psoas compartment nerve block.[5]
As well as initial symptoms, the accumulation of blood in the retroperitoneal space also compresses the femoral nerve. This may lead to weakness in extending the knee (with reduced patellar reflex) and weakness in flexing the hip.[8]
A magnetic resonance imaging (MRI) scan may be used to identify the collection of blood, although this is often not performed if bleeding is a medical emergency.[3]
The management will depend on the location of the bleeding, the stability of the patient and the cause. Thus, the patient needs to be closely monitored and the etiology investigated. The initial management must include adequate fluid resuscitation. Treatment options for a retroperitoneal bleed may range from angiographic embolization to surgery in severe cases. [9]
