Sažetak
Uvod. Na gornjoj strani zadnjeg luka prvog vratnog pršljena (atlas) nalazi se žleb kojim prolazi kičmena arterija na svom putu ka lobanjskoj duplji, a praćena je potpotiljačnim živcem. Prisustvom koštane varijacije, žleb može biti pretvoren u nepotpuni/potpuni kanal, što može dovesti do kompresije struktura koje njime prolaze, a tako i pojave simptoma vertebrobazilarne insuficijencije. Cilj rada bio je da se odrede učestalost i dimenzije morfoloških varijacija na zadnjem luku atlasa. Materijal i metode. Istraživanje je sprovedeno na 41 atlasu koji pripadaju Osteološkoj zbirci Zavoda za antomiju Medicinskog fakulteta Univerziteta u Novom Sadu i Medicinskog fakulteta Univerziteta u Nišu. Atlasi su prema izgledu gornje strane zadnjeg luka klasifikovani u tri klase, a potom su merene maksimalna širina i visina nepotpunog/potpunog kanala kojim prolazi kičmena arterija. Merenja su vršena u javno dostupnom programu za analizu i obradu slika ImageJ. Rezultati. Najzastupljeniji su atlasi klase I, na čijem je zadnjem luku prisutan žleb kičmene arterije (78,05%), dok su najmanje zastupljeni pršljenovi klase III, sa žlebom koji je pretvoren u potpuni koštani kanal (7,32%). Ne postoji statistički značajna razlika između merenih parametara sa desne i leve strane posmatranih atlasa. Zaključak. Morfometrijskom analizom gornje strane zadnjeg luka atlasa pokazano je da postoje varijacije izgleda žleba kičmene arterije čiji je značaj opisan u radu.
