Objective To summarize the current evidence about risk factors for the neurological outcomes for posterior stroke in Latin America patients

Background Ischemic stroke of the posterior cerebral circulation accounts for up to 25% of all cases and poses challenges because of its variable presentation, especially in the Latino population where there is a lack of evidence.

Design/Methods We systematically searched 4 databases up to July 2024 for studies evaluating patients with subsequent stroke in Latin America. The risk of bias was assessed with the Newcastle Ottawa scale and ROBINS-I.

Results

Three cohort studies (1284 patients) conducted in Chile, Brazil and Mexico were selected. One of the studies found that at 6 months, most patients had a good prognosis (mRS score 0-2) (45%; 95% CI: 34-5-56-0). Another study found that for the development of Homonymous Visual Field Defects, vertebral artery dissection (OR: 12.65; 95% CI: 1.01-157.2) and hypercoagulable states (OR: 12.30; 95% CI: 1.02-147.9) were risk factors. Another study found that in patients treated with thrombectomy, the main factors for mortality, good prognosis and intracranial hemorrhage were a baseline NIHSS > 10 (OR: 62.78; 95% CI: 1.67-2358.8), proximal basilar occlusion V4 (OR: 10.26; 95% CI: 1.45-72.15) and an expanded treatment in cerebral infarction (eTICI) of 0-2a (OR: 8.29; 95% CI: 1.06-64.45), respectively.

Conclusions

Despite the scarce evidence, neurological outcomes in patients with posterior stroke are related to factors such as elevated NIHSS, basilar occlusion, eTICI, among others; however, future studies are needed to evaluate the Latin American population.
