Abstract		Aortic endoprosthesis are divided according to its shape, site of application, and construction material. Regarding the shape, there are tubular, unilateral and bifurcational endoprosthesis. Tubular are used mostly for treatment the thoracic aneurysm, and less for treatment of the abdominal aneurysms. For exclusion of abdominal aneurysm the bifurcational prosthesis is mostly used. Aortic endoprostheses are made of metallic support and prosthetic part. Supportive elements are made of stainless steel or nitinol, while the prosthetic part is made of dacron or PTFE. Metallic part of prosthesis attaches prosthesis to healthy part of aorta, above and below aneurysm, like sutures. It expands and gives support to the prosthesis. The procedure is precisely described for thoracic and abdominal aortic aneurysms. We describe the possible complications and the mechanism of leakage and its diagnosis. In the study are presented two cases of patients with aneurysm of thoracic aorta and one case with abdominal aorta, successfully treated in our Institution. The follow-up results after 2 years, in the patients with thoracic aortic aneurysm, and 6 months follow up in the patient with abdominal aortic aneurysm showed no signs of clinical or imaging complications. In conslusion, we were trying, on the basis of our experiences and results that have been recently published, to evaluate this method of treatment.
Summary		Aortne endoproteze delimo po obliki, mestu aplikacije in po materialu, iz katerega so zgrajene. Po obliki so tubularne ali razcepiščne. Prve uporabljamo za premoščanje anevrizem prsne aorte in redkeje trebušne aorte. Anevrizme trebušne aorte večinoma premoščajo z razcepiščno endoprotezo. Aortne endoproteze so zgrajene iz opornega kovinskega dela in proteze. Oporni del je narejen iz nerjavečega jekla ali nitinola. Proteza je iz tkanine dakrona ali politetrafluoretilena. Oporni del pritrdi protezo na neprizadeti del aorte nad in pod anevrizmo namesto šivov. Protezo razpre in ji daje oporo. Natančno je opisan postopek uvajanja endoproteze in premoščanja anevrizme prsne in trebušne aorte. Prikazani so možni zapleti in natančno je opisan mehanizem notranjega puščanja in njegovo ugotavljanje. V naši ustanovi smo z aortno endoprotezo uspešno premostili anevrizmo aorte trem bolnikom. Pri dveh v področju descendentnega dela prsne aorte in tretjemu v področju trebušne aorte, nižje od ledvic. Prvemu bolniku smo premostili prevdoanevrizmo, ki je povzročala hripavost, drugemu zaradi drugega poznega zapleta z deformacijo endoproteze z notranjim puščanjem po dvakratnem zdravljenju z endoprotezo v tujini. Tretji bolnik se je endovaskularno zdravljenje z endoprotezo kot manj invazivno opcijo odločil zaradi prestalih operacij na odprtem srcu. V zaključku smo na osnovi naših izkušenj in objavljenih rezultatov poskušali oceniti vrednost metode.
