Acute aneurysm rupture on PED deployment. Patient 9 presented with SAH, WFNS grade 5, and a 34-mm fusiform paraclinoid aneurysm treated on day 1 with 2 PEDs. A, Anteroposterior oblique left ICA DSA demonstrates the same narrowing of the terminal ICA (black arrow) distal to the fusiform aneurysm neck. B, Two PEDs have been deployed (white arrows outlining the proximal PED, point of overlap of the 2 PEDs in the previously narrowed portion of the distal ICA, and the distal PED in the proximal MCA M1 segment). Note the aneurysm is rerupturing with contrast extravasation superior to the dome. The patient died the same day.
