Spontaneous ilio-psoas hematomas complicating intensive care unit hospitalizations.

Age, anticoagulation, a high body mass index and dialysis seem to be risk factors of developing an ilio-psoas hematoma in ICU. Iatrogenic ilio-psoas hematomas complicated by disseminated intravascular coagulopathies are more at risk of leading to death. It is noteworthy that activated partial thromboplastin time above the therapeutic range was not a good predictor of developing a hematoma for patients who received unfractioned heparin therapy.
