Restoration of hepatopetal portal flow in a cat with left hepatic arteriovenous malformation following left hepatic division resection and staged attenuation of acquired portosystemic shunts.

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
A 5-month-old Munchkin cat was referred for hematuria. Computed tomographic angiography revealed hepatic arteriovenous malformation (HAVM) within the left lateral liver lobe and multiple acquired portosystemic shunts (APSSs), in addition to a bladder calculus. Following medical management, the cat underwent attenuation of arterioportal communications. Because ligation of the left hepatic artery did not normalize portal pressure, the left hepatic division was resected. Surgical ligation of a subset of the APSSs was performed 1 month later. Postoperatively, clinical signs improved, hepatopetal portal flow was restored, and biochemical liver function parameters normalized. The remaining APSSs regressed spontaneously. To our knowledge, based on the English-language literature, this is the first reported case of feline or canine HAVM in which liver function parameters normalized.
