ABSTRACT
OBJECTIVE:
The authors investigated the clinical and radiographic characteristics of patients who exhibited contrast extravasation on initial computed tomographic angiography (CTA) and assessed the its association with hematoma expansion.METHODS:
Ninety six patients who were diagnosed with intracerebral hemorrhage and who received CTA within 12 hours from initial onset of symptoms and who received a follow up brain CT within 48 hours from the initial CTA between April 2004 and March 2007 were retrospectively assessed. Contrast extravasation was defined as the presence of high-density material within the hematoma. Patients were classified into the extravasation and no extravasation groups. Clinical and radiographic variables were compared between the two groups.RESULTS:
Fifteen patients (19%) demonstrated presence of extravasation on initial CTA. A significantly higher rate of hematoma expansion was seen in the extravasation group compared to the non extravasation group (47% vs 17%, p=0.027). Mean time from onset of symptoms to initial CTA was significantly shorter in the extravasation group (3.5+/-1.3 hours vs 7.6+/-2.5 hours, p0.001).CONCLUSIONS:
Earlier detection of extravasation using CTA may help in identifying possibly life threatening complications caused by hematoma expansion. However, a larger prospective cohort is warranted to validate this result.Key words
