Proctalgia secondary to rectal arteriovenous malformation and inferior mesenteric vein stenosis in a patient post liver transplant.
Article in CVIR endovascular, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundChronic proctalgia can have a major impact upon quality of life. There are many potential aetiologies however, in some patients no cause can be identified. CASE PRESENTATION: We present a patient post liver transplant with intractable proctalgia, despite multidisciplinary management including opioids, nerve blocks and surgical intervention. An underlying rectal arteriovenous malformation (AVM) was subsequently identified and successfully treated with embolotherapy. The onset of symptoms coincided with the development of inferior mesenteric vein stenosis, likely leading to engorgement of the malformation due to impaired venous outflow. Neovascularisation secondary to the liver transplant procedure may also have contributed to growth of the lesion.
conclusionThis is a rare presentation of rectal AVM. These lesions can be treated with minimally invasive embolisation/sclerotherapy and should be considered in cases of unexplained proctalgia.
