title: [Intrarenal veins. Study of the segmental angioarchitecture and intersegmental anastomoses].
abstract: Fifty human adult venous casts were studied in a examine of the disposition and anastomoses of the intrarenal veins. The Vinylite injection and hydrocloric acid corrosion method was used. Casts with two main venous trunks (32%), three trunks (36%) and four trunks (32%) were found. Large longitudinal and transversal anastomotic branches among the main venous trunks do not content the kidney venous segmental division, in contrast to intrarenal arteries. The longitudinal anastomoses are named of 1st. order (sinusal), of 2nd. order (pyramidal) and of 3rd. order (marginal), in relation to interlobar veins, arciform veins, and stellate veins, respectively.
