Interventional treatment of peripancreatic aneurysms: can one strategy fit all?
Article in CVIR endovascular, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo identify the frequency and association of visceral arterial (VA) stenosis in peripancreatic aneurysms (PPAs) and to develop a uniform, more detailed treatment strategy for PPAs in case of accompanying VA stenosis, as current guidelines do not adequately address this constellation. MATERIALS AND
methodsPatients with PPAs diagnosed at a tertiary care hospital were retrospectively analyzed. In case of multiple PPAs, the aneurysm with the highest aneurysm-to-vessel ratio (AVR) within the celiac-mesenteric collateral circulation was classified as the primary aneurysm and categorized as "critical" or "non-critical" based on the risk of organ ischemia. Celiac artery and superior mesenteric artery stenoses were graded as low (< 50%), high (> 50%), or total occlusion. Treatment strategies were based on VA stenosis severity, aneurysm classification, and morphology. Treatment strategies included endovascular, surgical and watch-and-wait management.
resultsThirty-one patients with PPAs were included with a total of 53 aneurysms; mean aneurysm size: 12.5 ± 7.9 mm (range 5-38 mm), AVR: 3.5 ± 2.1 (range 1-11.3). The superior and inferior pancreaticoduodenal arteries as well as the pancreaticoduodenal arcade were affected in most cases (67.9%). AVR was significantly higher in cases of aneurysm rupture (6.2 ± 2.8; p = 0.031). Celiac artery stenosis was present in 87.1%. Aneurysm size and occurrence of active bleeding did not correlate (p = 0.925). 11 patients presented with critical aneurysms, with 10 patients requiring individually tailored treatment. Non-critical aneurysms were treated with coil embolization in most cases.
conclusionCA stenosis, aneurysm position, and AVR significantly influence treatment decisions. Individualized approaches based on anatomical and hemodynamic factors are needed in PPA treatment.
