Super-selective arterial embolization in the therapy of non-ischemic priapism-a single-center study and literature review.
Article in CVIR endovascular, 2026. 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
backgroundThe goal of our analysis is to provide technical information and clinical long-term data on arterial embolization for non-ischemic priapism. Furthermore, this study presents a comprehensive literature review.
methodsWe analyzed patient data from June 2005 to June 2025 at a large university hospital, focusing on patients with non-ischemic priapism lasting over 1 week, unresponsive to conservative treatment, and referred for arterial embolization. Age, symptom etiology, initial diagnostic modality, embolic agent, uni- or bilateral arterial supply of the fistula/pseudoaneurysm, technical success, clinical outcome, need for a second attempt, erectile dysfunction, adverse events, and mean follow-up time needed were assessed. Findings were contextualized with studies from the past two decades.
resultsA total of 15 male patients with non-ischemic priapism due to blunt, penetrating trauma or of idiopathic origin, were included in this analysis. The embolic agents chosen included gelatin sponge, polyvinyl alcohol particles, autologous clot, microcoils, and a combination of microcoils with gelatin sponge or polyvinyl alcohol particles. Technical success was achieved in 14 patients (93.3%). A second or third intervention was needed in three cases (20.0%) to achieve clinical success. Documented adverse events included procedure-related findings such as penile skin changes and deviation in two patients (13.3%). No new cases of erectile dysfunction were reported (0%).
conclusionOur findings support super-selective arterial embolization as a safe, technically successful, and minimally invasive therapy option for non-ischemic priapism after conservative measures fail. Moreover, our data suggest that arterial embolization is associated with long-term symptom improvement without significantly impairing sexual function.
