What is Cavocaval anastomosis?
What is Cavocaval anastomosis?
Cavocaval anastomoses They are the links between v. cava superior and v. cava inferior. Blood can flow in both directions, depending on the placement of the obstacle.
Which is a common site for portocaval anastomosis?
The site of this anastomosis is the upper part of the anal canal. The anastomosis between the paraumbilical veins, which run in the ligamentum teres as portal veins, and small epigastric veins, which are systemic veins. The site of this anastomosis is the umbilicus.
Where are the major Portocaval anastomoses?
A portocaval anastomosis or porto-systemic anastomosis is a specific type of anastomosis that occurs between the veins of the portal circulation and those of the systemic circulation.
Is Portacaval anastomosis harmful?
When there is a blockage of the portal system, portocaval anastomosis enable the blood to still reach the systemic venous circulation. The inferior end of the esophagus and the superior part of the rectum are potential sites of a harmful portacaval anastomosis.
What is scapular anastomosis?
The scapular anastomosis is a system connecting certain subclavian artery and their corresponding axillary artery, forming a circulatory anastomosis around the scapula. It allows blood to flow past the joint in case of occlusion, damage, or pinching of the following scapular arteries: Transverse cervical artery.
Which arteries make up the scapular anastomosis?
Scapular and shoulder anastomoses The branches of the scapular anastomoses come from the subclavian artery and the axillary artery. Those of the shoulder are derived from the different segments of the axillary artery. The first member of the scapular anastomoses arises from the thyrocervical trunk.
What is the difference between caput succedaneum and Cephalhematoma?
Caput succedaneum is similar to cephalohematoma as both involve unusual bumps or swelling on the newborn’s head. However, the main difference is that lumps caused by bleeding under the scalp is cephalohematoma, whereas lumps caused by scalp swelling due to pressure is known as caput succedaneum.
What is the clinical significance of the scapular anastomosis?
Clinical Significance. Collateral circulation via scapular anastomosis: If the subclavian and axillary arteries are blocked anywhere between 1st part of subclavian artery and 3rd part of axillary artery, the scapular anastomosis acts as a potential pathway (collateral circulation) between the first part of the subclavian artery and…
What does the dorsal scapular artery anastomose with?
The dorsal scapular artery anastomoses with the subscapular artery, providing an alternate route to the 3rd part of the axillary artery in the event of a slowly forming occlusion. The suprascapular artery branches off from the thyrocervical trunk, which in turn arises from the first part of the subclavian artery.
What is the anatomy around the scapula?
Around the body of scapula: It takes place between the: Suprascapular artery, a branch of the thyrocervical trunk from the first part of the subclavian artery, Circumflex scapular artery, a branch of the subscapular artery from the third part of the axillary artery Deep branch of the transverse cervical artery; a branch of the thyrocervical trunk.
What is the suprascapular artery?
Suprascapular artery, a branch of the thyrocervical trunk from the first part of the subclavian artery, Circumflex scapular artery, a branch of the subscapular artery from the third part of the axillary artery Deep branch of the transverse cervical artery; a branch of the thyrocervical trunk.
