Endovascular Therapy significantly increases symptomatic hemorrhage over Standard Medical Therapy
The rate of sICH for the EVT group was 6.8% vs. 0.7% in the medical therapy group. This difference was significant (OR, 10.36; 95% CI, 3.92–27.40; P=0.009), but should not be surprising, since EVT requires devices to be advanced directly into the occluded vessel, and the clot retrieval (regardless of technique) can damage the vessel.
