Recurrent artery of Heubner infarction in patients with ruptured AcomA treated by microsurgical clipping. Neuroimaging studies from 3 patients with ruptured AcomA treated by microsurgical clipping are shown. Admission head CT shows SAH (arrows, first column) as hyperattenuated blood in the subarachnoid space. Vascular imaging demonstrates the AcomA (arrows, second column) in each patient by CTA. Postclipping neuroimaging demonstrates cerebral infarction in the RAH territory (arrows, third column) by fluid-attenuated inversion recovery MR imaging (patients 1 and 2) or NCCT (patient 3).

↵a Percentages refer to the number of patients with non-missing values (46 clip and 48 coil). P values are from the likelihood ratio test using propensity scores and odds ratios, and resulting 95% CIs are derived from the logistic model that includes both treatment and propensity scores (see “Materials and Methods” section).
