Physician-modified fenestrated/inner-branched endovascular aortic repair for distal aortic arch aneurysm after stent graft migration: a case report.
Article in General thoracic and cardiovascular surgery cases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundsOpen surgical repair remains the gold standard for aortic arch aneurysms, and endovascular treatment options are limited in high-risk patients. We report successful treatment of a distal aortic arch aneurysm using physician-modified fenestrated/inner-branched endovascular aortic repair (PM-F/iBEVAR), suggesting its feasibility as an alternative strategy. CASE PRESENTATION: A 50-year-old man presented with a distal aortic arch aneurysm enlargement after stent graft migration following preemptive thoracic endovascular aortic repair. The patient had significant neurological sequelae with impaired activities of daily living and was considered unsuitable for conventional arch replacement after multidisciplinary discussion. PM-F/iBEVAR was performed, and an inner branch was sutured only to the left subclavian artery in this patient. Although a type II endoleak was detected on postoperative day 3, the type Ia endoleak had resolved, and patency of the arch branch vessels was well maintained. The patient was discharged without any complications. At 6 months, the aneurysm remained stable without enlargement.
conclusionsThis case report suggests that PM-F/iBEVAR may be a feasible option for patients at high risk for open surgical repair with anatomically challenging distal aortic arch aneurysms.
