Sažetak

Moždani udar je nagli gubitak funkcije mozga koji se dešava zbog prekida cerebralne cirkulacije. Odlikuje se ekspeditivnim razvojem kliničkih simptoma tokom 24 sata, koji kod nekih pacijenata dovode do smrti. Kod više od 80% pacijenata sa moždanim udarom uzrok je vaskularna insuficijencija i ova vrsta moždanog udara je ishemijska. To je hitno stanje kod kojeg je neophodno ubrzano zbrinjavanje radi optimalne prognoze. Evaluacija ishemijskog moždanog udara u vecini slučajeva postiže se kompjuterizovanom tomografijom, bez upotrebe kontrasta, zahvaljujuci njenoj širokoj upotrebi. Detaljna pretraga literature kroz Medline i EBSCO baze podataka obavljena je korišćenjem sledecih ključnih reči: kompjuterska tomografija, akutni ishemijski moždani udar i rani znaci. lzabrani su originalni radovi, metaanalize i pregledni papiri za poslednjih 10 godina, sa pristupačnim tekstovima na engleskom jeziku, kao i značajne reference koje mogu da doprinesu shvatanju čitalaca. Nakon detaljnog pregleda literature izdvojili smo i opisali sledeće rane znake akutnog ishemijskog moždanog udara: znak insularne trake, potamnjenje nucleus lentiformisa, znak hiperdenziteta arterija, hipodenzitet hemisfera i fokalna hipoatenuacija. Ovi znaci su povezani sa posledicama celijske hipopefuzije i citotoksičnim edemom. Cilj ovog rada bio je pregled literature o ulozi kompjuterizovane tomografije kod pacijenata s ranim znacima akutnog ishemijskog moždanog udara, koja treba da posluži kao edukativni materijal koji ilustruje te nalaze.
