Description
  • The detailed spatial arrangement of the vasa vasorum (VV) of the human great saphenous vein (HGSV) was demonstrated in qualitative and quantitative terms. Materials and Methods: Segments of the HGSV taken from cadavers 12-24 h post mortem and from patients undergoing aortocoronary bypassing were studied by light microscopy of India-ink-injected specimens and by scanning electron microscopy of vascular corrosion casts. Results: Arterial feeders were found to approach the HGSV from nearby arteries every 15 mm forming a rich capillary network within the adventitia and the outer two thirds of the media in normal HGSV, while in HGSV with intimal hyperplasia capillary meshes extended into the inner layers of the media. Within the media, capillary meshes ran circularly. Postcapillary venules drained centrifugally towards the adventitial venous vessels which finally formed venous drainers running adjacent to the arterial feeders. Three-dimensional morphometry of vascular corrosion casts of VV revealed that di

  • Detailní prostorové uspořádání vasa vasorum (VV) lidské vena saphena magna (HGSV) bylo studováno kvalitativně a kvantitativně. Materiál a metoda: Segmenty HGSV získané jak postmortálně, tak peroperačně z pacientů indikovaných k aortokoronárním bypassům, byly studovány světelně mikroskopicky po nástřiku cév tuší, a v rastrovacím elektronovém mikroskopu po injekcích pryskyřice. Výsledky: U zdravých žil přicházejí přívodné cévy k HGSV v intervalech kolem 15 mm a přecházejí do bohaté kapilární sítě uložené v adventicii a zevnéch dvou třetinách medie. U HGSV s intimální hyperplázií prorůstá kapilární síť do nejhlubších vrstev medie, v níž mají oka kapilární sítě převážně cirkulární orientaci. Postkapilární venuly se postupně sbírají do adventiciálních žil, majících stejnou úpravu jako arteriální větve. 3D morfometrie korozivních preparátů VV ukázala, že průsvit arteriálních VV kolísal mezi 11,6 a 36,6 ?m, kapiláry byl silné 4,7-11,6?m a žíly 11,6-200,3?m. Závěr: Uspořádání VV svědčí pro vysokou metabolicko (cs)
