Table 5:

Six-month control angiography results in regard to aneurysm size^a

Degree of Occlusion	Small	Large	Giant	Total No.	%
Total occlusion (%)	136 (93.8%)	56 (87.5%)	27 (90%)	219b	91.6b–91.2c
Still filling	9	8	3	20d	8.4%
Total	145	64	30	239a	100

^aOne patient with 1 aneurysm died after the treatment; 8 patients with 11 aneurysms (9 small and 2 large) have not yet undergone the 6-month control angiography. Therefore, a total of 12 aneurysms (4.8%) did not have control angiography.

^bIncluding 1 patient who had subarachnoid hemorrhage in the fourth month and was retreated with additional PEDs for her remaining aneurysm filling.

^cRepresents the ratio of aneurysms that were occluded in the 6-month control without retreatment.

^dSeven were retreated. Seven of the remaining showed further thrombosis with resultant aneurysm occlusion, and 6 are pending the next control after the discontinuation of the clopidogrel.
