During an intracranial aneurysm coiling case in ipp 9 a 3d dsa spin was performed to evaluate the aneurysm pre treatment.The 3d was non-diagnostic and we see a large amount of artifact of unknown cause and filling defects.Patients head was taped, 3cc per second for a total of 21cc was injected via power injector.The patient was intubated with respirations held during the spin and was paralyzed.A second 3d was attempted with the same problem.The patient received an additional 21cc of contrast due to this failure with still non-diagnostic imaging.Manufacturer response for bi-plane, artis q (per site reporter): when siemens was working on the system the day before, it could be possible that they did not complete the qa portion for the 3d spin.They were contacted and this was completed.After this the 3d spin was working.
