Parallel Endografting And Chimney Endovascular (PEACE) registry outcomes in emergency repair of complex abdominal aortic aneurysms.

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
backgroundChimney endovascular aneurysm repair (chEVAR) techniques have been described to manage a group of patients who are unsuitable for either open aortic aneurysm surgery or a variety of standard endovascular repair techniques. The aim of this study was to assess the long-term clinical outcomes of chEVAR in emergency settings for patients with abdominal aortic aneurysms that have complex morphology.
methodsThis was a multicentre retrospective study that included all consecutive patients undergoing urgent chEVAR with at least one chimney/parallel graft up to June 2021. Outcomes that were captured included 30-day mortality, long-term overall survival, aneurysm-related mortality, chimney-related complications, and target vessel patency.
resultsSome 118 patients (mean(s.d.) age of 77(8) years; 72.0% male) underwent urgent or emergency chEVAR, 78 (66.1%) due to aortic rupture. The mean(s.d.) number of chimneys used per patient was 1.6(0.7). Technical success was achieved in 90.6% of patients, with a 30-day mortality rate of 17.7%. The mean follow-up was 4(3) years. Estimated overall survival was 69 ± 5% at 3 years, 45 ± 6% at 5 years, and 32 ± 6% at 7 years. Freedom from aneurysm-related mortality was 58 ± 6% at 5 years and 53 ± 6% at 7 years. In patients surviving the perioperative 30-day interval, freedom from aneurysm-related mortality was 73 ± 6% at 5 years and 66 ± 7% at 7 years. Primary target vessel patency at 5 and 7 years was 87 ± 4%, with renal arteries most frequently affected. Late reinterventions occurred in 16.1% of patients, mostly for type Ia endoleaks (8 of 25 reinterventions (32%)) and type Ib endoleaks (5 of 25 reinterventions (20%)).
conclusionIn this Parallel Endografting And Chimney Endovascular (PEACE) registry study, chEVAR was associated with a high rate of technical success and acceptable early outcomes, but, in the longer term, was associated with high rates of reintervention and mortality. It appears to represent a reasonable alternative technique for patients presenting as an emergency with complex aortic aneurysm morphology when standard open and endovascular techniques are not feasible.
