Role of intravascular ultrasound use in patients undergoing endovascular aortoiliac aneurysm repair.

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
backgroundThis study aimed to assess the accuracy of aortic measurements obtained by intravascular ultrasound (IVUS) compared with intra-arterial contrast agents (IACA), and to evaluate the role of IVUS in endovascular repair of abdominal aortic aneurysms (EVAR), particularly in patients with chronic kidney disease (CKD). PATIENTS AND
methodsThis prospective single-center study which was conducted in vascular surgery departments at Al-Azhar university hospitals from December 2017 to December 2022. It included eighty patients complaining of infrarenal abdominal aortic aneurysm (AAAs). According to treatment policy, patients were divided into two groups: Group A: treated by EVAR with an intra-arterial contrast agent. Group B: treated by EVAR with intravascular ultrasound;
resultsReceiver operating characteristic (ROC) curve analysis showed that access artery diameter (right or left iliac) measured by IVUS significantly predicted aneurysm sac size reduction after EVAR (AUC = 0.88, P = 0.003). At a cut-off > 14 mm, the access artery diameter yielded 100% sensitivity, 80% specificity, positive predictive value (PPV) of 83.3%, and negative predictive value (NPV) of 100%. A moderate agreement was observed between computed tomography angiography (CTA) and IVUS in assessing aortic dimensions. Larger access artery diameters (> 14 mm) were associated with less sac regression, possibly due to suboptimal distal sealing and increased risk of type Ib endoleaks.
conclusionIVUS is a valuable and accurate imaging tool compared to CTA for aortic measurements during EVAR, especially beneficial for patients with renal impairment by reducing contrast load and radiation exposure.
