Abstract

Minimalno invazivni endovaskularni zahvati u domeni intervencijske radiologije obuhvaćaju perkutane intervencije na aorti, njezinim glavnim ograncima te drugim perifernim arterijama. Ovi zahvati najčešće se koriste u endovaskularnom popravku aneurizmi aorte, no koriste se i u drugim vaskularnim patologijama kao što su pseudoaneurizme, disekcije, okluzije i rupture. Nakon ovakvih zahvata nužna je redovna radiološka kontrola bolesnika radi utvrđivanja uspješnosti učinjenog zahvata te detekcije mogućih komplikacija radi potrebe za sekundarnim intervencijama. Trenutačni općeprihvaćeni zlatni standard u radiološkoj kontroli i praćenju bolesnika nakon endovaskularnih zahvata jest kompjuterizirana tomografska angiografija (CTA) s magnetskom rezonancijom (MRA) kao suplementarnom metodom. Ove dijagnostičke slikovne metode su iznimno skupe, nisu uvijek primjenjive u svih pacijenata, koriste potencijalno štetne kontrastne medije za funkciju jetre i bubrega u bolesnika. CTA izlaže bolesnike štetnom ionizirajućem zračenju, a MRA se ne može primijeniti u bolesnika s metalnim implantatima ili u klaustrofobičnih. Usavršavanjem ultrazvučnih metoda i neškodljivih ultrazvučnih kontrastnih medija ova široko dostupna, jednostavna i neionizirajuća dijagnostička metoda te njezini razni modaliteti mogu se koristiti kao jednakovrijedna zamjena standardnim slikovnim metodama.

Abstract (english)

The minimal invasive endovascular interventions in the field of intervention radiology include perkutaneous interventions on the aorta, its main branches and other peripheral arteries. These procedures are most commonly used in endovascular repair of aortic aneurysms, but are also used in other vascular pathologies such as pseudoaneurisms, dissections, occlusions and ruptures. Following these interventions, a regular radiological control of the patient is necessary to determine the effectiveness of the performed procedure and to detect possible complications in the need of secondary interventions. The current commonly accepted gold standard for radiotherapy and follow-up of patients after endovascular procedures is computed tomography angiography (CTA) with magnetic resonance angiography (MRA) as a supplemental method. These diagnostic imaging methods are quite expensive, not applicable in all patients and they demand potentially harmful contrast media for patients liver and kidney function. CTA exposes patients to harmful ionizing radiation, and MRA can not be used in patients with metal implants or fear of confined spaces. Further improvements of ultrasonography methods and ultrasound contrast agents this widely available, simple and non-radiating diagnostic method and its various modes can be used as an equivalent replacement for standard imaging modalities.
