Abstract
Periferna arterijska bolest je stenozirajuća, aneurizmatska ili okluzirajuća bolest krvnih žila ekstremiteta nastala kao posljedica ateroskleroze-sužavanja promjera stijenke krvne žile zbog nakupljanja plaka kojeg čine štetni produkti iz krvi. Obično je bolest starije populacije i osnovni su joj rizični čimbenici nezdrav način života, izloženost stresu, pušenje, genetska predispozicija, šećerna bolest i hipertenzija. Klinički se bolest očituje klasičnim simptomima klaudikacija, ali ako se ne liječe na vrijeme mogu dovesti do značajnijih posljedica kao što su ishemija ili nekroza tkiva. Bolest se dijagnosticira klasičnim fizikalnim pregledom i laboratorijskim testovima uz mjerenje ABI koji višestruko olakšava dijagnozu i potvrđuje moguću pojavu nekih drugih krvožilnih poremećaja. Uz tehnike koje koriste zračenje kao što su CT ili DSA, mogu se koristiti MR ili ultrazvučni pregled prilikom kojih se pacijent ne izlaže zračenju. Ultrazvuk je neinvazivna, brza, jednostavna i učinkovita metoda za dokazivanje periferne arterijske bolesti. Ne koristi ionizacijsko zračenje i ne pokazuje štetan učinak na tkivo, stoga se pretraga može ponavljati. Primarno se koristi duplex utrazvuk kao kombinacija pulsnog dopplera i B - moda uz kolor doppler. Njime se mjeri brzina i smjer protoka krvi, a prikazuje se spektralnom krivuljom. Njezin je oblik shematski prikaz stupnja stenoze u patološki promjenjenoj krvnoj žili. B -modom prikazuje se dvodimenzionalna slika izgleda krvne žile u različitim nijansama sive što ovisi o intenzitetu refleksije ultrazvučnoga vala. Kolor dopplerom pokazuje se smjer kretanja krvi u bojama koje se dogovorno određuju tako da se krv veće frekvencije, koja ide prema sondi označi jednom (najčešće crvena), a ona od sonde, manje frekvencije drugom bojom (plava). Crvena predstavlja arterijsku, plava vensku krv. Najvažniji je dio ultrazvuka sonda ili pretvarač koja služi kao emiter i apsorber UZV valova, a za prikaz krvnih žila koriste se visokofrekventne linearne sonde. PAB se liječi konzervativnim putem-promjenom stila života, konzumacijom lijekova i hodanjem, endovaskularnim putem ili kirurškim putem uz postojanje jasne indikacije.
Abstract (english)
Peripheral arterial disease includes stenosis disease, occlusive disease or aneurysmatic disease that are caused by atherosclerosis-narrowing the diameter of the blood vessel wall because of plaque which is produced by products from the blood. PAD is usually presented between older people and the main risk factors are unhelthy lifestyle, stress, smoking, genetic predisposition, diabetes and a hypertension. This disease is presented with tipical simptoms of claudication, but if it is not treated in time it causes serious complications such as ischemia or necrosis. PAD can be diagnosed with normal clinical review or laboratory tests, but sometimes it includes ABI test that is a great option for making diagnose of some other vascular disorders too. Instead of using techniques with ionization such as CT or DSA we can use other ones like MRI or ultrasonography without exposure patient to unnecessary radiation. Ultrasound methods are noninvasive, fast, simple and effective methods for diagnosing PAD. They do not use radiation or show some negative effects on the tissue, so that is a reason why it can be repeated. Normally professionals use duplex ultrasound which is a combination of B-mode and pulse doppler while using color doppler. It is used for measuring direction and flow velocity. In the end , it is showed like a spectral graph. This graph is showing stenosis size or shape in patologic condition of blood vessel. B-mode is used for making a planar picture review in different shades of gray and that depends on reflection intensity by ultrasound. Direction of blood flow is showed by color doppler. It uses colors for checking out a frequency of the blood. One with a higher frequency which is moving to probe is arterial (red), and other one with a lower frequncy and movement from the probe is venious (blue). The most important part of ultrasound device is a probe. That is a transmitter and reciever of ultrasonic waves.Usually, we use high frequency linear probes. PAD is treated with different ways such as changing lifestyle, taking medication therapy or walking, using endovascular methods or by surgery (do not forget indications).
