Super-selective renal artery embolization (SRAE) for iatrogenic and traumatic renal hemorrhage.
Article in BMC surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 present the radiological and clinical outcomes of super-selective transcatheter renal artery embolization in patients with renal injury hemorrhage, and share our experience.
methods43 patients with renal injury hemorrhage who underwent 46 SRAEs were enrolled in this retrospective review study. Records, images, and outcomes were reviewed. The individual embolic method and its observed effects were investigated.
resultsAngiography showed free extravasation in 25 angiograms, pseudoaneurysm in 15 angiograms, and arteriovenous fistulas in 1 angiogram. Most patients achieved initial clinical success (38/43, 88.4%), and 41 patients achieved final clinical success (41/43, 95.3%). 9/11 patients who adopted empirical embolization achieved initial clinical success (81.8%). In our study, the combination of PVA particles and micro-coils has emerged as the most commonly utilized material combination (24/46, 52.2%). Significant differences in hemoglobin levels were observed before and after the embolization procedure (p = 0.026, 95%CI: 1.03-15.54). Post-embolization clinical follow-up showed no evidence of recurrent hematuria, progression of hematoma, hypertension, and no reflux of the embolic agent.
conclusionThough SRAE showed satisfactory results across a broad range of renal injury hemorrhage, there are still some aspects that need attention: (1) Surgical procedure should be understood, including the surgical site, access routes, and placement of implants, such as double-J stents. (2) In cases where identifying the bleeding point proves challenging, consider the possibility of an accessory renal artery.
