Spontaneous retroperitoneal hemorrhage (SRH) is a distinctive clinical pathology of retroperitoneal bleeding without a preceding history of trauma.

For a broader discussion, including other etiologies, please refer to the parental article on retroperitoneal hemorrhage.

Clinical presentation

Clinical presentation may be vague and varied:

no inciting history
no evidence of cutaneous bruising
back, lower abdominal or groin pain
hemodynamic instability
fall in hemoglobin

Pathology

The pathophysiology and pathogenesis of spontaneous retroperitoneal bleeding are unclear. Many hypotheses have been put forth:

diffuse vasculopathy and arteriosclerosis of small retroperitoneal vessels renders them friable and prone to rupture
anticoagulation induced immune microangiopathy may cause an unrecognised minor trauma in the microcirculation to cause a hemorrhage

Etiology

Spontaneous retroperitoneal hemorrhage is uncommon and is almost exclusively seen in association with:

rupture of aortic or visceral artery aneurysm
rupture of a pathological lesion in a retroperitoneal organ (renal and adrenal)
anticoagulation states
coagulopathies
- factor IX deficiency
- factor X deficiency
- von Willebrand disease
- antiphospholipid syndrome
haemodialysis
