A 72-year-old woman is admitted to the hospital with a painful right foot. A CT scan examination reveals a thrombotic occlusion of the femoral aery in the proximal pa of the adductor canal. Which aery will most likely provide blood supply to the leg through the genicular anastomosis?,
High-Yield Explanation
The Lateral Circumflex Femoral Aery arises from the Deep Femoral (Profunda Femoris) aery of the thigh and sends a descending branch down the length of the femur to anastomose with the Superior Medial Genicular Aery and the Superior Lateral Genicular Aery. The medial circumflex femoral aery is responsible for supplying blood to the head and neck of the femur, and it does not anastomose with distal vessels at the knee. The first Perforating Aery of Deep Femoral Aery sends an ascending branch that anastomoses with the Medial Circumflex Femoral and the Inferior Gluteal Aery in the buttock. The inferior gluteal aery is a branch of the Internal Iliac; it has impoant anastomotic supply to the hip joint.
