Preliminary report of contrast-enhanced computed tomography for patients with a percutaneous cardiopulmonary support system.

The purpose of this study was to investigate a suitable protocol of contrast-enhanced computed tomography (CECT) in cases with a cardiopulmonary support system. Contrast-enhanced computed tomography with intra-arterial injection (IAI) of contrast medium (CM) via a perfusion cannula showed sufficient contrast enhancement in 2 cases of cardiac decompensation (CD). Contrast-enhanced computed tomography with intravenous injection of CM showed insufficient and delayed contrast enhancement of the aorta in 2 cases of CD and 3 cases of pulseless electrical activity. We encourage administration of CM by means of IAI.
