Purpose:
Evaluation of carbon dioxide (CO2) as contrast medium for detection of intraabdominal haemorrhage.
Method:
We performed in 5 patients 7 DSA examinations (one with upper and three with lower gastrointestinal bleeding, one traumatic spleen rupture) using an iodinated contrast-medium and CO2 for the localisation of haemorrhage.
Results:
With iodinated contrast medium it was possible to localise the haemorrhage in three of 5 patients. With CO2 the localisation was possible in all cases. There were no side effects.
Conclusion:
CO2 is useful for detection of intraabdominal bleeding. Even in cases with negative angiographic results with iodinated contrast medium, CO2 may enable localisation of the bleeding vessel. Because of this, we use CO2 and iodinated contrast media in all cases of intraabdominal haemorrhage. Further studies are required.
