Clinical benefits and risks of the wall-push technique in endovascular repair of abdominal aortic aneurysm with severely angulated neck: a case report.

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
Background: Endovascular aneurysm repair (EVAR) has become the preferred treatment for infrarenal abdominal aortic aneurysms (AAA), offering reduced morbidity and faster recovery compared with open surgery. However, patients with complex neck anatomy pose significant technical challenges, and current treatment approaches carry inherent risks. Learning from and summarizing experiences from these complex cases is crucial for advancing EVAR techniques. Case summary: An 80-year-old female with a 10-year history of conservatively managed infrarenal AAA complained of intermittent abdominal pain for 1 week. Computed tomography angiogram (CTA) demonstrated a tortuous infrarenal AAA with a tapered neck. Aneurysmal dilatation and severe calcification of bilateral iliac arteries and tortuous aortoiliac access were also shown. EVAR was performed successfully using Gore Excluder C3 stent-grafts (W.L. Gore & Associates, Flagstaff, AZ, USA). During deployment, inadvertent forward displacement of the guidewire caused an iatrogenic abdominal aortic dissection above the left renal artery. The false lumen was immediately coil-embolized with five interlock coils, successfully excluding the dissection flap and restoring antegrade flow. The procedure was completed uneventfully, with the stent-graft well positioned, patent, and free of endoleak. Discussion: The case highlights both the utility and risks of advanced EVAR techniques in complex anatomy. The wall-push technique, while useful for severe neck angulation, requires meticulous guidewire control and carries risk of vessel injury. Key preventive measures include continuous fluoroscopic monitoring, team communication, consideration of safety wires, and careful preoperative assessment. The learning curve for advanced techniques is steep, emphasizing the need for proper training, experience, and comprehensive preoperative planning using three-dimensional CTA reconstruction.
