A case report of an absence of the left inferior thyroid artery with the thyroid IMA artery compensating.

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
purposeThe inferior thyroid artery is an artery of the anterolateral neck and supplies blood to the thyroid gland and surrounding structures in the neck. Here, we report an anatomical variation of the left inferior thyroid artery in a male cadaver. We aimed to enrich the data on these anomalies, which can have implications for surgical interventions and clinical outcomes. CASE PRESENTATION: During routine neck dissection of a 64-year-old male donor, the inferior thyroid artery was identified bilaterally. On the left side, the inferior thyroid artery was absent and replaced by the thyroid IMA artery. The thyroid IMA artery formed a U-shaped course and gave branches to the lower part of the thyroid gland. In addition, the thyroid IMA artery arose from the brachiocephalic trunk. Furthermore, the branch of the thyroid IMA artery ascended parallel to the left recurrent laryngeal nerve. There was no anatomical variation of the right inferior thyroid artery.
conclusionsThe current study describes a significant anatomical variation as the absence of the left inferior thyroid artery compensated by the thyroid IMA artery. This variation has significant implications for clinical practice and surgical procedures, particularly for surgery in the neck, axilla, and superior mediastinum. Preoperative imaging and surgical panning should be considered to avoid the likelihood of complications during clinical practice and surgery.
