Abstract
Posebne mikromorfološke karakteristike vaskularizacije trigeminalnog nerva i gangliona i bliski neurovaskularni odnosi sa okolnim sudovima, kao i njihov mogući klinički značaj bili su prvi razlozi ove studije. Drugi cilj studije bio je da se prouče morfološke i imunohistohemijske karakteristike ektopičnih i ganglijskih neurona u trigeminalnom nervu i ganglionu. Krvni sudovi 25 trigeminalnih nerava odraslih osoba, posle injiciranja mešavine tuša i želatina u arterijski sistem, mikrodisekovani su i proučavani pod stereomikroskopom. Četrdeset humanih trigeminalnih nerava i gangliona poreklom od 20 osoba, dobijenih rutinskom obdukcijom, proučavani su posle histološkog bojenja metodom Klüver-Barrera, trihromnih bojenja Azan i Masson tehnikom i imunohistohemijskih reakcija na neke od neuronskih markera, neuropeptida i neurotransmitera. Trigeminalne grančice namenjene nervu, od dve do pet, polazile su od dve ili tri od sledećih arterija: superolateralna pontinska (92%), a. cerebelli inferior ...anterior (ACIA) (88%), inferolateralna pontinska (72%) i a. cerebelli superior (ACS) (12%). Trigeminalne arterijice su bile prosečnog prečnika od 0,220 mm. Jedan sud je vaskularizovao bilo motorni deo trigeminalnog stabla, ili senzorni deo ili oba. Trigeminalni sudovi su formirali proksimalni i distalni arterijski prsten oko nerva. Proksimalni prsten se nalazio u nivou spoja korenog dela nerva i ponsa. Njegove centralne grane su pratile trigeminalni nerv na putu ka glavnom senzornom i motornom jedru, dok su periferne longitudinalne grančice pratile snopove nerva ka ganglionu. Distalni arterijski prsten, često nekompletan, obuhvatao je središnji deo nerva, neposredno pre njegovog ulaska u arahnoidni omotač. Najčešće uočen neurovaskularni kontakt trigeminalnog nerva bio je sa ACS (20%), sa petroznom ili Dendijevom venom (24%) i sa ACIA (12%). Inferolateralno stablo i meningohipofizialno stablo, koja polaze od unutrašnje karotidne arterije, kao i grane srednje moždanične arterije su bili glavni sudovi koji su vaskularizovali trigeminalni ganglion. Trigeminalne arterijice koje su od njih polazile su bile prosečnog prečnika od 0,220 mm...

Specific micromorphological characteristics of the trigeminal nerve and ganglion blood supply and close neurovascular relationships with surrounding vessels, as well as their possible clinical significance were the first reasons for this study. The second aim of this study was to examine the morphology and the immunohistochemical features of displaced and ganglion cells in the trigeminal nerve and ganglion. The vasculature of 25 adult trigeminal nerves and ganglions were microdissected and examined under the stereoscopic microscope, after injecting their arteries with a mixture of India ink and gelatin. Forty human trigeminal nerves and ganglions of twenty persons, obtained during routine autopsy, were examined following Klüver-Barrera, Azan and Masson trichrome histological stainings, and immunohistochemical reactions against certain neuronal markers, neuropeptides and neurotransmitters. The trigeminal nerve vessels, which varied between two and five in number, arose from two or three... of the following arteries: the superolateral pontine (92%), anterior inferior cerebellar (AICA) (88%), inferolateral pontine (72%), and superior cerebellar (SCA) (12%). The trigeminal vascular twigs had a mean diameter of 0.220 mm. A single vessel may supply either the motor portion of the nerve root, or the sensory portion or both. The trigeminal vasculature formed the proximal and distal rings. The proximal ring was located at the trigeminal root entry zone. Its central branches extended along the trigeminal nerve to the principal sensory and motor trigeminal nuclei while its peripheral longitudinal twigs followed the trigeminal nerve fascicles. The incomplete distal arterial ring embraced the middle portion of the trigeminal nerve before the level of its entrance into the arachnoid sleeve. The most frequent contact of the trigeminal nerve was noticed with the SCA (20%), the petrosal or Dandy’s vein (24%), and the AICA (12%). The inferolateral trunk, the meningohypophyseal trunk, branches of the internal carotid artery, and the middle meningeal artery were the main vessels supplying the trigeminal ganglion...
