Portal Vein Arterialization as a Lifesaving Strategy for Hepatic Artery Injury in Robotic Hepatectomy.

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
backgroundRobotic vascular resection and reconstruction is a challenging procedure. Portal vein arterialization (PVA) can offer an efficient solution in those cases in which the hepatic artery cannot be reconstructed.1.Can J Surg 64:e173-e182;2.The Paul Brousse Hospital Experience. HPB (Oxford) 16:723-738;3.J Am Coll Surg 207:e1-6; PVA increases oxygen supply to the remaining part of the liver, promotes liver regeneration, and prevents liver failure.Majlesara A, Golriz M, Ramouz A, et al. Portal vein arterialization as a salvage method in advanced hepatopancreatobiliary surgery. Br J Surg. 2024;111. In this multimedia article, we describe a patient who was treated with PVA for a robotic hepatic artery injury during robotic left-liver-first anterior radical modular orthotopic right hemihepatectomy (Rob-Larmorth).5.Ann Surg Oncol 31:5636-5637
methodsA 52-year-old male patient was admitted with epigastric pain. Further imaging showed intrahepatic cholangiocarcinoma involving the root of the right anterior branch of the portal vein. Following multidisciplinary consultation, surgical resection was recommended as the primary approach. The robotic technique was chosen in this operation, with preoperative anticipation of needing Rob-Larmorth. Unfortunately, the left hepatic artery sustained unintended damage during skeletonization of the duodenal ligaments. Anastomosis could not be performed due to severe damage to the distal end intima. We utilized PVA technology to anastomose the hepatic artery to the portal vein. Finally, Rob-Larmorth and PVA were successfully performed.
resultsThe surgery took 490 min and the estimated blood loss was approximately 300 mL. No blood transfusion was performed. Postoperatively, the patient recovered smoothly without liver failure, although percutaneous drainage was required due to bile leakage. Pathological examination revealed moderately to poorly differentiated bile duct cell carcinoma (T2N0M0, stage II). No recurrence was observed during the 12-month follow-up. DISCUSSION: PVA can be an effective solution when no other revascularization options are available. Implementing PVA as a bridging procedure increases oxygen delivery to the remnant liver, facilitating regeneration and reducing the risk of liver failure. The development of arterial collaterals is a significant concern for individuals undergoing PVA. Complications reported after PVA include early shunt thrombosis, portal hypertension, and a notable 90-day mortality rate.1.Can J Surg 64:e173-e182 However, Majlesara and colleagues found no evidence of postoperative liver damage associated with PVA. They also reported low morbidity rates and no associated mortality for both one- and two-stage embolization of the arterioportal shunt.Majlesara A, Golriz M, Ramouz A, et al.

conclusionsPVA can offer an effective solution when hepatic artery reconstruction is not feasible.
