ABSTRACT=Background: To investigate the effect of ADAPT versus Solumbra technique in the treatment of acute intracranial atherosclerosis-related large vessel occlusion (LVO). 
Methods: Patients with acute atherosclerosis-related LVO who had undergone endovascular treatment were retrospectively enrolled into two groups: the Solumbra and ADAPT group. The clinical data were analyzed. 
Results: 104 patients were enrolled with 48 in the Solumbra and 56 in the ADAPT group. The mean time from femoral access to recanalization was significantly (P<0.05) shorter in the ADAPT than the Solumbra group. The recanalization time at the first pass line was significantly shorter in the ADAPT group than in the Solumbra group (17±10.21 vs. 26±15.55 min, P=0.02). However, the rate of switching to the alternative was significantly higher in the ADAPT group than that in the Solumbra group (46.42% vs. 33.33%, P=0.01). Eighty-two patients had eventual recanalization, resulting in a final recanalization rate of 78.85%. At three-month clinical follow-up for all patients, the good prognosis rate reached 51.92% with good prognosis in 24 patients (50%) in the Solumbra and 30 (53.57%) in the ADAPT group. The rate of symptomatic intracranial hemorrhage was 14.5818.75% (n=9) in the Solumbra and five 19.64% (n=11) in the ADAPT group. The mortality rate was 21.15% (22/104). Among 80 (76.92%) patients who had angiographic follow-up (3-30 months), five (6.25%) patients experienced instent stenosis, and two (2.5%) experienced asymptomatic stent occlusion. 
Conclusion: In patients with acute intracranial atherosclerosis-related large vessel occlusion, clinical outcomes treated using the ADAPT technique are comparable with those using the Solumbra technique, and more patients need additional remedial measures if treated with the ADAPT technique.
