Abstract

Intervencijski zahvati pod nadzorom ultrazvuka poboljšavaju preciznost i sigurnost izvođenja
različitih medicinskih zahvata. Pružaju više prednosti u usporedbi s tradicionalnim metodama,
kao što su vizualizacija anatomskih struktura u realnom vremenu, manji rizik za razvoj
komplikacija, minimalno invazivni pristup koji dovodi do manje traume tkiva i kraćeg
postoperativnog oporavka pacijenata, smanjena izloženost zračenju i cijena izvođenja. Neka od
ograničenja ultrazvuka su ovisnost o znanju i vještinama operatera i slabija mogućnost prikaza
koštanog tkiva i drugih tkiva kroz koja ultrazvučni valovi slabije prodiru.

Još jedna od prednosti široki je raspon zahvata u kojima se može primijeniti ultrazvuk. Rade se
endovaskularni pristupi postavljanja katetera, stentova i širenja suženja krvnih žila balonskom
dilatacijom. Biopsije tkiva primjenjuju se u dijagnostičke svrhe, poput otkrivanja karcinoma.
Postupcima perkutane ablacije destruiraju se tumorske mase. Drenažnim zahvatima odstranjuju
se nakupine tekućina, apscesi ili ciste iz abdomena, prsišta, zglobova i drugih dijelova tijela.

Ultrazvuk se može koristiti i kao pomoćna metoda u drugim zahvatima. Intravaskularni
ultrazvuk napredna je slikovna metoda putem koje se kateterom uvedenim izravno u krvnu žilu
vizualizira njezina unutrašnjost i dobiva uvid u morfologiju kakvu nije moguće prikazati drugim
tradicionalnim metodama. Intravaskularni ultrazvuk značajno je utjecao u radu intervencijske
kardiologije pružajući bolje razumijevanje vaskularnih bolesti i poboljšavajući sigurnost i
uspješnost koronarnih intervencija.

Abstract (english)

Ultrasound-guided interventional procedures enhance the accuracy and safety of various
medical interventions. They offer several advantages compared to traditional methods, such as
real-time visualization of anatomical structures, lower risk of complications, minimally
invasive approach leading to less tissue trauma and shorter recovery for patients, reduced
radiation exposure and lower costs. Some limitations of ultrasound include dependence on
knowledge and skills of the operator and reduced ability to image bone and other tissues that
ultrasound waves penetrate poorly.

Another advantage is the wide range of procedures in which ultrasound can be applied.
Endovascular approaches include catheter placement, stent insertion and balloon dilation to
widen narrowed blood vessels. Tissue biopsies are used for diagnostic purposes, such as
detecting cancer. Percutaneous ablation procedures destroy tumor masses. Drainage procedures
remove fluid collections, abscesses or cysts from the abdomen, chest, joints and other parts of
the body.

Ultrasound can also be used as an auxiliary method in other procedures. Intravascular
ultrasound is an advanced imaging technique where a catheter introduced directly into the blood
vessel visualizes its interior and provides insights into the morphology that cannot be depicted
by other traditional methods. It has significantly impacted interventional cardiology by
providing a better understanding of vascular diseases and improving the safety and efficacy of
coronary interventions.
