Embolization of Rectal Arteries for Treating Hemorrhoidal Disease Using a Combination of Microspheres and Microcoils: A Pilot Study.
Article in Cardiovascular and interventional radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo investigate the feasibility and initial results of superior (SRA) and middle (MRA) rectal artery embolization for patients with symptomatic hemorrhoidal disease. MATERIALS AND
methodsProspective, single-center cohort that included ten consecutive patients (Goligher classification was II in 70% and III in 30%.) who underwent SRA and MRA embolization using a combination of microspheres and metallic coils, who completed a follow-up period of 12 months. Technical success was defined as embolization of SRA and MRA whenever MRA dominance was observed. Clinical success was defined as an improvement of the hemorrhoid severity score (HSS) and quality of life (QoL) scores without recurrence, with the need for additional treatment. Procedure-related adverse events (AEs) were recorded and defined according to CIRSE classification as minor or major complications.
resultsTechnical success was achieved in all patients. SRA was embolized in 100% of patients and MRA in 80%. The improvement in HSS and QoL scores was 88% and 88% (p < 0.05), respectively, without clinical recurrence in the 12-month follow-up. One patient had a major complication (level D), a rectal ischemia and perforation of the rectosigmoid leading to perforative acute abdomen with sepsis that required surgical treatment (Hartmann's procedure).
conclusionEmbolization of both SRA-MRA using a combination of microspheres and metallic coils was feasible and significantly improved HSS and QoL scores. One major complication was observed and therefore it is essential to further investigate the safety boundaries of this technique.
