artery,

blood vessel that conveys blood away from the heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

. Except for the pulmonary artery, which carries deoxygenated blood from the heart to the lungs, arteries carry oxygenated blood from the heart to the tissues. The largest arterial trunk is the aortaaorta
, primary artery of the circulatory system in mammals, delivering oxygenated blood to all other arteries except those of the lungs. The human aorta, c.1 in. (2.54 cm) in diameter, originates at the left ventricle of the heart.

, microscopic blood vessel, smallest unit of the circulatory system. Capillaries form a network of tiny tubes throughout the body, connecting arterioles (smallest arteries) and venules (smallest veins).

, the latter connecting with the veinsvein,
blood vessel that returns blood to the heart. Except for the pulmonary vein, which carries oxygenated blood from the lungs to the heart, veins carry deoxygenated blood. The oxygen-depleted blood passes from the capillaries to the venules (small veins).

). Other important arteries are the subclavian and brachial arteries of the shoulder and arm, the carotid arteries that lead to the head, the coronary arteries that nourish the heart itself, and the iliac and femoral arteries of the abdomen and lower extremities. The walls of the large arteries have three layers: a tough elastic outer coat, a layer of muscular tissue, and a smooth, thin inner coat. Arterial walls expand and contract with each heartbeat, pumping blood throughout the body. The pulsating movement of blood, or pulsepulse,
alternate expansion and contraction of artery walls as heart action varies blood volume within the arteries. Artery walls are elastic. Hence they become distended by increased blood volume during systole, or contraction of the heart.

The patient's dorsal compartment pressures were measured at 120 mmHg, confirming a diagnosis of ACS of the foot and a disruption of the anterior tibial artery.
Thereafter, the posterior tibial artery was catheterized distal to the pseudoaneurysm with a 185 cm 0.
Interestingly, exception being the posterior tibial artery diameter in Judo female athletes, which presented no statistical significant difference (p > 0.
In addition, if a mean systolic pressure of 125 mm Hg was found in the right dorsal pedis artery, but a mean systolic pressure of 130 mm Hg was found in the right posterior tibial artery, the posterior tibial mean systolic pressure should be used when using the following ratio to calculate ABI.
The tibial head receives an artery that branches off the posterior tibial artery before or after tibiofibular bifurcation.
The aorta, common iliac artery (CIA), external iliac artery (EIA), common femoral artery (CFA), superficial femoral artery (SFA), deep femoral artery (DFA), popliteal artery (PA), anterior tibial artery (ATA), tibio-peroneal trunk (TPT), peroneal artery (PEA) and posterior tibial artery (PTA) were examined in each leg.
Reversed island flaps such as the peroneal artery flap, anterior tibial artery flap, and posterior artery flap have the disadvantage of major leg artery sacrifice.
The inflow artery was common femoral artery superficial femoral artery popliteal artery and posterior tibial artery in 7 (17.
We also aim for revascularization targeted to the angiosomal territory of the tissue loss, such as a non-healing wound or gangrene in the setting of tibial artery occlusion.
Abnormal pedal pulses Dorsal pedis and posterior tibial artery pulses either absent or 1 present and 1 weak.
