Recipient artery localization for assist bypass in subarachnoid hemorrhage using composite three-dimensional digital subtraction angiography/digital subtraction venography and indocyanine green videoangiography: A case report.
Article in Surgical neurology international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: In high-flow bypass (HFB) procedures for ruptured internal carotid artery (ICA) blister-like aneurysms, precise localization of the recipient artery for an assist superficial temporal artery-middle cerebral artery (STA-MCA) bypass is challenging when subarachnoid hemorrhage (SAH) is present. Case Description: A 59-year-old woman presented with SAH due to a ruptured ICA blister-like aneurysm. She underwent trapping of the ICA with HFB using the radial artery and an additional assist STA-MCA bypass. Preoperative composite images from three-dimensional digital subtraction angiography and digital subtraction venography enabled localization of the cortical recipient artery relative to identifiable veins. Intraoperative indocyanine green (ICG) videoangiography confirmed the recipient artery's flow characteristics. Both bypasses remained patent, and postoperative MRI showed no ischemic complications. The patient was discharged with modified Rankin Scale. Conclusion: The combination of composite preoperative imaging and intraoperative ICG videoangiography allowed precise identification of the cortical recipient artery and contributed to favorable surgical outcomes.
