Changes in Abdominal Artery Diameter in Patients Treated for Acute Aortic Dissection.

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
backgroundMesenteric ischemia significantly increases intraoperative mortality in patients with acute aortic dissection (AAD). The arterial diameter affects both blood flow and arterial resistance. There are no data in the literature on changes in arterial diameter in patients with AAD. It has already been demonstrated that changes in arterial diameter can be observed in patients with non-occlusive intestinal ischemia. The aim of this study was to compare the arterial branches of the abdominal aorta in patients with AAD preoperatively and postoperatively.
methodsPreoperative and postoperative contrast-enhanced computed tomography scans of 25 patients who had undergone the frozen elephant trunk procedure for the treatment of AAD were reconstructed and retrospectively analyzed with detailed medical data of the patients.
resultsIn patients without AAD at the level of the abdominal aorta, statistically significant differences were observed when comparing the diameter of the superior mesenteric artery (
conclusionSignificant changes in visceral artery diameter were observed at the abdominal aortic level in patients both with and without aortic dissection. Chronic or non-occlusive mesenteric ischemia may be associated with a lack of adjustment in arterial diameter. Patients with AAD of the abdominal aorta are more susceptible to occlusion of the inferior mesenteric artery.
