Unmasking of a missed right hepatic artery pseudoaneurysm by biliary decompression following Roux-en-Y hepaticojejunostomy for Strasberg type E3 bile duct injury.

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
Bile duct injuries (BDI) after cholecystectomy often coexist with vascular injuries, but hepatic artery pseudoaneurysms may be missed on initial imaging. We report a right hepatic artery (RHA) pseudoaneurysm that manifested as haemobilia only after biliary decompression by Roux-en-Y hepaticojejunostomy for a Strasberg type E3 injury. A 28-year-old man presented 4 weeks after open cholecystectomy with obstructive jaundice. Magnetic resonance imaging confirmed a Strasberg type E3 stricture and identified a missed 8-mm RHA pseudoaneurysm. Following hepaticojejunostomy, haematemesis occurred on postoperative day 3. Computed tomography angiography demonstrated enlargement of the pseudoaneurysm to 12-mm with arteriobiliary communication. Covered stenting was followed by recurrent bleeding requiring glue-lipiodol embolization, complicated by non-target splenic embolization and an abscess requiring percutaneous drainage. The patient recovered and remained asymptomatic at three months. This case suggests that relief of biliary hypertension can unmask contained pseudoaneurysms and reinforces the importance of routine preoperative arterial-phase imaging in complex BDI.
