Single-institution experience with Shape medical polymer sponge embolization as adjunct therapy for rapid aortic remodeling in the multi-modal management of complex persistent large false lumens following 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
Persistent false lumen (FL) pressurization after endovascular repair of aortic dissection is associated with increased aortic morbidity and mortality. Shape memory polymer sponge devices (IMPEDE-FX, Shape Medical) have shown promise in promoting sac regression after endovascular aortic repair in abdominal aortic aneurysms in ongoing trials. Here, we report the adjunct use of these devices as part of a multimodal approach to achieve FL occlusion in three patients (average age, 59 years; male = 2, female = 1) with limited options for the management of their persistent large FL following type A (n = 1) and type B (n = 2) aortic dissections between March and December 2024. FL thrombosis and aortic remodeling were achieved in all three patients based on postoperative imaging within 1 to 6 months after intervention. There was one mortality in a Marfan's patient secondary to Zone 0 aortic rupture 2 months postoperatively, distant from areas of previous intervention. Our early clinical experience with the Shape memory sponge in managing large, complex persistent FL is encouraging, but further prospective studies are needed.
