Interlobular vein

The intrarenal veins accompany the arteries. There are two types of interlobular veins draining the cortex. One type originates at the surface of the kidney as stellate veins draining the most superficial parts of the renal cortex. Most interlobular veins are of the second type, which originates in the cortex as a result of the joining of venules from the peritubular plexus. Both types accompany interlobular arteries... 

FIGURE 5.38 Pictorial presentation of the microscopic structure of the liver. The picture shows the classical liver lobulus. The functional acinus and its three zones are at the left. The acinal zones are marked by numbering them 1-3. These zones correspond to the direction of blood flow from the portal arteries (PA) to the terminal veins (TV). Zone I corresponds to the periportal area in classical liver pathology, zone 2, the interlobular region (midzone), and zone 3, centrelobular region. ... 

In the porta hepatis, the proper hepatic artery divides into the right branch (from which the cystic artery emerges) and the left branch (from which a middle hepatic artery occasionally emerges). The branches of the hepatic artery run close to the portal veins and may even (rarely) coil round them in places. An arterial sphincter is located prior to the further division of the hepatic artery into smaller branches. There are anastomoses between the arterial branches and the hepatic vein. By way of an arteriolar sphincter (46), the interlobular arteries branch into intralobular arterioles, supplying the lobules of the liver with arterial blood. The arterial blood enters the sinusoids either through terminal branches or through arterioportal anastomoses and mixes with the portal blood. The pressure in the hepatic arterioles is 30-40 mm Hg. (36, 46, 61)... 

The perivascular fibrous capsule (R Glisson, 1654) commences in the hepatic porta as a tree-like branching framework of connective tissue surrounding the interlobular vessels. It also surrounds the central hepatic vein and its small tributaries, which are joined to the parenchyma by radial fibres as well as being established in the portal tracts. This prevents a suction-induced collapse of the venous vessels as a result of respiration-dependent negative pressure in the pleural cavity. The perivascular connective tissue, known as Glisson s capsule, extends fine secondary trabeculae into the parenchyma. They contain the intralobular biliary, lymphatic and blood capillaries.

The interlobular septa extend from the pleural surface of the lung inward, and surround the secondary lobule. They consist of connective tissue, house pulmonary veins, and lymphatics and belong to the peripheral in-... 

Other rare vascular complications of sarcoidosis (limited to a few case reports) include pulmonary arterial stenoses from granulomatous involvement of the vessels, extrinsic compression of pulmonary arteries by enlarged hilar lymph nodes or fibrosing mediastinitis (6), pulmonary veno-occlusive disease (resulting from obstruction of interlobular septa veins by granulomata or perivascular...
