Surgical treatment of a giant aneurysm of the superior mesenteric artery in a patient with systemic lupus erythematosus.

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
Visceral artery aneurysms (VAAs) are rare, representing ˂2% of all arterial aneurysms in adults, with superior mesenteric artery aneurysms (SMAAs) being the third most common type. Systemic lupus erythematosus (SLE) is associated with vascular complications, including vasculitis and antiphospholipid syndrome, which may contribute to aneurysm formation. However, SMAAs in SLE patients are seldom reported. A 45-year-old male patient with SLE and chronic abdominal pain was presented to our clinic. Imaging revealed a 56-mm SMAA with thrombosis and stenosis. Due to rupture risk, open surgical repair was performed using a reversed saphenous vein graft, successfully revascularizing four mesenteric branches. Recovery was uneventful. Although endovascular techniques are less invasive, open surgical repair remains the preferred approach for complex aneurysms involving multiple branches. This case underscores the role of SLE-related vasculitis in aneurysm formation and highlights the need for early diagnosis and intervention.
