Spontaneous Thrombosis of a Long-Segment Hepatic Artery Aneurysm During Conservative Management: A Case Report on an 11-Year Follow-Up.
Article in Cureus, 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
Hepatic artery aneurysms (HAAs) can rupture, yet the management of small, asymptomatic, long-segment lesions remains controversial. We report a 64-year-old man with an incidentally detected, long-segment aneurysmal change extending from the proximal common hepatic artery to the distal proper hepatic artery (approximately 80 mm). CT showed irregular, multilobulated ectasia with a focal saccular component (17 mm), an intimal flap, and mural thrombus, suggesting aneurysmal degeneration after dissection; a subtle dissection-like change was also suspected in the celiac trunk. Given the small maximal diameter, absence of symptoms, and concern for hepatic/biliary ischemia with intervention, close imaging surveillance was chosen. Progressive thrombosis led to complete occlusion at 5.5 years, with preserved hepatic enhancement and a more prominent left-gastric-right gastric collateral pathway. The aneurysm remained stably thrombosed without ischemic complications over 11 years. This case highlights that carefully selected, asymptomatic, anatomically complex HAAs may be managed conservatively with strict long-term follow-up.
