Algorithm for assessing the shagginess of the abdominal aorta lumen based on three-dimensional analysis of its morphology

An approach is proposed for quantitative assessment of the shagginess of the lumen of a pathologically altered aorta, taking into account the three-dimensional morphology of its internal surface. An algorithm for assessing local shagginess has been developed and implemented, and an integral criterion for shaggyness in the anatomical region has been proposed. The algorithm was tested on data from two patients with a shaggy and a smooth lumen. The results obtained are in good agreement with the results of visual assessment by expert surgeons and are confirmed by clinical outcomes during surgery.
