Hemobilia due to Hepatic artery pseudoaneurysm secondary to collateral circulation formation after liver trauma: a case report.
Article in BMC surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundHemobilia due to rupture of hepatic artery pseudoaneurysm and recurrent hemorrhage caused by hepatic artery collateral circulation are both rare complications after liver trauma. There have been a number of separate reports of both complications, but no cases have been reported in which the two events occurred in the same patient. Here we report a recurrent hemorrhage in the bile duct due to hepatic artery pseudoaneurysm secondary to collateral circulation formation after hepatic artery ligation in a patient with liver trauma. CASE PRESENTATION: A 52-year-old male patient was admitted to our hospital for liver trauma (Grade IV according to the American Association for the Surgery of Trauma (AAST) grading system) with active bleeding after a traffic accident. Hepatic artery ligation was performed for hemostasis. Three months after the surgery, the patient was readmitted for melena and subsequent hematemesis. Selective angiography examination revealed the formation of collateral circulation between the superior mesenteric artery and right hepatic artery. Moreover, a ruptured hepatic artery pseudoaneurysm was observed and transcatheter arterial embolization (TAE) was performed for hemostasis at the same time. After the treatment, the patient recovered very well and had an uneventful prognosis until the last follow-up.
conclusionFor patients with hepatic trauma, the selection of the site of hepatic artery ligation and the diagnosis and treatment methods of postoperative biliary hemorrhage are crucial for the prognosis of the disease.
