Renal artery located above the renal vein. Supernumerary renal arteries (two or more arteries to a single kidney) are the most common renovascular anomaly, occurrence ranging from 25% to 40% of kidneys. Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys. RAS is typically diagnosed with duplex ultrasonography of the renal arteries. It is treated with the use of balloon angioplasty and stents, if necessary. Atherosclerosis can also affect the renal arteries and can lead to poor perfusion of the
Fibular artery the "perone" (pronounced pair-uh-knee) means "pin of a brooch" or "buckle". Fibular artery In anatomy, the fibular artery (also known as the peroneal artery) supplies blood to the lateral compartment of the leg. It arises from the tibial-fibular trunk. The fibular artery arises from the bifurcation of tibial-fibular trunk into the fibular and posterior tibial arteries in the upper part of the leg proper, just below the knee. It runs towards the foot in the deep posterior compartment of the leg, just medial to the fibula. It supplies a perforating branch to both the lateral and anterior compartments of the
