Retrograde carotid fat pad flip method for carotid exposure during carotid endarterectomy.

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: Exposure of the distal internal carotid artery (ICA) during carotid endarterectomy (CEA) can be challenging in anatomically difficult cases. We present the retrograde carotid fat pad (CFP) flip method, a cranial-first, layer-oriented exposure strategy based on preservation of the fibro-fatty layer overlying the carotid sheath. Methods: The CFP was used as a surgical descriptor for the fibro-fatty tissue overlying the carotid sheath within the carotid triangle. In this method, the cranial CFP boundary is established first along the posterior belly of the digastric muscle, after which the preserved CFP is mobilized and flipped laterally with the carotid sheath. We retrospectively reviewed 61 consecutive patients who underwent CEA using this planned exposure strategy between 2022 and 2024. Results: The cohort included 6 high carotid bifurcations and 2 twisted ICAs. Carotid exposure was completed as planned in all patients, with no conversion. The mean carotid system exposure time was 66.0 ± 13.6 min, the mean operative time was 144.7 ± 25.4 min, and the median estimated blood loss was 5 mL. Great auricular nerve dysfunction occurred in 3 patients, was limited to lower auricular sensory disturbance, and resolved by the 6-month follow-up. No stroke, myocardial infarction, or death occurred within 30 days. Conclusion: The retrograde CFP flip method is a feasible cranial-first exposure strategy for CEA. It may help create a shallow, wide, fat-free field toward the distal ICA when early cranial orientation and stable distal ICA exposure are desirable.
