Comparison of Neurologic and Radiographic Outcomes with Solitaire versus Merci/Penumbra Systems for Acute Stroke Intervention

Table 6

The outcomes of the present study compared to the results from large mechanical thrombectomy trials.

Present study		Merci [9]	Multi-Merci [8]	Penumbra pivotal stroke [3]	SWIFT trial [10] (solitaire arm)	TREVO2 trial [7] (TREVO2 arm)
Sample, 𝑛	31	141	164	125	58	88
Recanalization, 𝑛 (%)	29 (93.5%)*	68 (48.2%)	112 (68.2%)	102 (81.6%)	48 (88.9%)	76 (86%)
symptomatic ICH, 𝑛 (%)	0 (0)	11 (7.8%)	16 (9.7%)	14 (11.2%)	1 (1.7%)	4 (4%)
3 month mortality, 𝑛 (%)	3 (10.3%)	61 (43.2%)	56 (34.1%)	31 (32.8%)	10 (17.2%)	29 (33%)
3 month mRS ≤ 2, 𝑛 (%)	20 (69%)	39 (27.6%)	59 (35.9% )	52 (41.6%)	32 (58.2%)	38/85 (40%)

∗This is the final recanalization rate which includes rescue treatment with other devices as well as iaTPA. With Solitaire FR device alone, the recanalization rate was 79.5%.
