Basilar Artery Occlusion Chinese Endovascular - BAOCHE
Contribution To Literature:
The BAOCHE trial showed that thrombectomy improved functional status; however, it resulted in more intracranial hemorrhage.
Description:
The goal of the trial was to evaluate thrombectomy compared with medical therapy among patients with acute stroke due to basilar artery occlusion.
Study Design
- Randomization
- Parallel
Patients with acute stroke due to basilar artery occlusion were randomized to thrombectomy (n = 110) vs. medical therapy alone (n = 107). Patients could receive intravenous thrombolysis according to provider discretion.
- Total number of enrollees: 217
- Duration of follow-up: 90 days
- Mean patient age: 64 years
- Percentage female: 27%
- Percentage with diabetes: 27%
Inclusion criteria:
- Patients 18-80 years of age with stroke due to acute basilar artery occlusion
- Symptom onset within the prior 6-24 hours
- Pre-stroke score of 0 or 1 on the modified Rankin scale score
Exclusion criteria:
- Intracranial hemorrhage
- Large infarct in the posterior circulation
Other salient features/characteristics:
- Thrombolysis was used in 14% of the thrombectomy group vs. 21% of the control group
Principal Findings:
The primary outcome, good functional status (modified Rankin scale score 0 to 3) at 90 days, occurred in 46% of the thrombectomy group vs. 24% of the medical therapy group (p < 0.001).
Secondary outcomes:
- Mortality at 90 days: 31% in the thrombectomy group vs. 42% in the medical therapy group (p = not significant [NS])
- Symptomatic intracranial hemorrhage: 6% in the thrombectomy group vs. 1% in the medical therapy group (p = NS)
- Procedural complications: 11% in the thrombectomy group
Interpretation:
Among patients with acute stroke due to basilar artery occlusion, thrombectomy was associated with improvement in good functional status. However, thrombectomy was also associated with increased symptomatic intracranial hemorrhage and procedural complications. Mortality was similar between the treatment groups.
