perforating arteries perforating arteries the perforating arteries are branches of the deep artery of the thigh, usually three in number, so named because they perforate the tendon of the adductor magnus to reach the back of the thigh. they pass backward near the linea aspera of the femur underneath the small tendinous arches of the adductor magnus muscle. perforating arteriesthe arteries of the gluteal and posterior femoral regions.the deep femoral artery and its major perforating branches (labeled at right center), as seen on right thigh, anterior view.detailssourcedeep femoral arteryidentifierslatinarteriae perforantesta98a12.2.16.031ta24696fma69460anatomical terminology the first perforating artery arises from the deep artery of the thigh above the adductor brevis, the second in front of this muscle, and the third immediately below it. first the first perforating artery (a. perforans prima) passes posteriorly between the pectineus and adductor brevis (sometimes it perforates the latter); it then pierces the adductor magnus close to the linea aspera. it gives branches to the adductores brevis and magnus, biceps femoris, and gluteus maximus, and anastomoses with the inferior gluteal, medial and lateral femoral circumflex and second perforating arteries. second the second perforating artery (a. perforans secunda), larger than the first, pierces the tendons of the adductores brevis and magnus, and divides into ascending and descending branches, which supply the posterior femoral muscles, anastomosing with the first and third perforating. the second artery frequently arises in common with the first. the nutrient artery of the femur is usually given off from the second perforating artery; when two nutrient arteries exist, they usually spring from the first and third perforating vessels. third/fourth the third perforating artery (a. perforans tertia) is given off below the adductor brevis; it pierces the adductor magnus, and divides into branches which supply the posterior femoral muscles; anastomosing above with the higher perforating arteries, and below with the terminal branches of the profunda and the muscular branches of the popliteal. the nutrient artery of the femur may arise from this branch. the termination of the profunda artery, already described, is sometimes termed the fourth perforating artery of elliott after the anatomist who first dissected its course. additional images cross-section through the middle of the thigh.
