Superselective anterior choroidal artery preoperative embolization of a giant choroid plexus carcinoma in an infant: case report and systematic review.

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
purposeChoroid plexus tumors (CPT), especially in pediatric patients, present a major surgical challenge due to their hypervascularity and frequent intraventricular location. Preoperative embolization has emerged as a strategy to minimize intraoperative blood loss and improve surgical outcomes, yet its application in large-volume tumors via the anterior choroidal artery (AChA) remains limited.
methodsWe report a case of a 10-month-old infant with a giant choroid plexus carcinoma (CPC) measuring 189 cm³, treated with superselective embolization through the AChA using Squid™ prior to surgical resection. A systematic review was also conducted, including 9 studies on preoperative embolization via AChA for CPTs, with attention to technique, tumor volume, agents used, and outcomes.
resultsMicrocatheterization beyond the plexal point of the AChA enabled safe delivery of the embolic agent, achieving substantial tumor devascularization without ischemic or hemorrhagic complications. Surgical resection was completed without intraoperative blood transfusion or neurological sequelae. The systematic review confirmed the rarity of embolization in tumors exceeding 100 cm³, highlighting our case as one of the largest successfully treated using this approach.
conclusionSuperselective preoperative embolization of choroid plexus tumors via the anterior choroidal artery is technically feasible and safe when performed beyond the plexal point. In high-risk pediatric cases with large-volume tumors, this strategy can significantly improve surgical safety and should be considered as part of a multimodal treatment approach.
