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).

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.

During laparoscopic cholecystectomy, dissection of a limited field is magnified on the video monitor, which indicates that a detailed anatomical knowledge of the possible variations in the anatomy of the cystic artery and its branches is very important to the surgeon (Hugh et al.
Technically, the dissection of the cystic artery and cystic duct is very precise and bleeding is easily controlled with less peri operative blood loss.
In 56% of cases (3), rupture of the cystic artery pseudoaneurysm occurs at the vesicular lumen, which clinically presents as upper gastrointestinal bleeding due to haemobilia.
The cystic artery is dealt with before cystic duct to avoid avulsion injury of the artery.
In all 33 specimen casts, the blood supply of extrahepatic bile duct was mainly obtained from the gastroduodenal artery, the proper hepatic artery, the right hepatic artery, the cystic artery and the posterior portal vein artery.
5cm cystic artery pseudoaneurysm (A) and a large collection (C) extending from the gall bladder fossa, surrounding the liver and extending down to the right paracolic gutter and into the pelvic brim.
Notable deficiency is the lack of comment on cystic duct and cystic artery dissection.
Reasons for conversion to open surgery included bleeding from avulsion of cystic artery (n=2), difficulty in controlling oozing of blood from liver bed (n=1), cholecystoduodenal fistula (n=1), adhesions/difficult anatomy at Calot's triangle (n=1), cystic duct avulsion (n=1) and common hepatic duct injury (n=1).
7,8] The course and length of the cystic artery in the Calot's triangle is variable.
Gall bladder perforation, bleeding from cystic artery and bile spillage were mostly encountered per-operative difficulties.
It is related behind to portal vein, medially to common hepatic duct and laterally to cystic artery.
Reasons for conversion were bleeding from cystic artery (n=2) liver bed bleeding (n=1) CHD injury (n=1) and chlecystoduodenal fistula (n=1).
