Grapefruit (Citrus × paradisi) is a citrus fruit whose rind, pith, thin inner covering and flesh provide different anatomical analogues in neurovascular bypass simulation. In the Cikla et al. 2020 distal anterior cerebral artery (dACA) side-to-side bypass trainer, a large grapefruit (12–15 cm diameter) is prepared with two longitudinal pole-to-pole rind incisions, demarcating approximately one-fifth of the fruit surface area; one strip is removed and the natural groove between sections is bluntly dissected to simulate the interhemispheric fissure.^[1]

The central column provides the path for separately inserted vessel substitutes; the grapefruit itself is not the vessel used for the anastomosis.^[1] The reported pith-to-central-column interior distance (mean 36.8±2.6 mm, n=20) approximates cadaveric brain cortex-to-corpus-callosum depth at the genu and at the level of the foramen of Monro. The study found different depths at the corpus-callosum midpoint and splenium.^[1]
