Description
Summary:Aim: To determine the value of three-dimensional (3D) digital subtraction angiography (DSA) in the detection of intracranial aneurysms and to compare 3D technique with DSA. Materials and Methods: A retrospective analysis of 50 patients with 60 intracranial aneurysms who underwent both conventional DSA and 3D-DSA for the evaluation of intracranial aneurysms was conducted. The presence of aneurysms, detection of aneurysmal neck, size, location, presence of additional and small aneurysms analyzed from the two protocols were compared. Results: Three-dimensional technique detected 54 aneurysms while conventional DSA detected 38 aneurysms. There was no correlation between aneurysm detection and aneurysm neck detection in the two technologies observed, but there was a difference in detection performance depending on the technology used. Three-dimensional technique detected 52 aneurysm necks while conventional DSA detected 24 aneurysm necks. There was a statistically significant and positive relationship between the detected size of the aneurysm using 3D technique and DSA technology. Three-dimensional technique detected 24 additional aneurysms while conventional DSA detected only six additional aneurysms. Conclusions: Three-dimensional technique are more successful in the detection of aneurysms, their necks and small aneurysms in comparison to digital subtraction angiography, but difference is not statistically significant. The size of the aneurysm statistically significant affects the aneurysm neck detection by conventional DSA. Cilj: Utvrditi vrijednost trodimenzionalne (3D) digitalne suptrakcijske angiografije (DSA) u detekciji intrakranijalnih aneurizama te usporediti 3D tehniku i DSA. Materijali i metode: Provedena je retrospektivna analiza 60 aneurizama koje su otkrivene u 50 pacijenata koji su podvrgnuti pregledu konvencionalnom DSA i 3D-DSA metodom u svrhu evaluacije intrakranijalnih aneurizama. Prisutnost aneurizme, detekcija vrata, veličine i lokacije aneurizme te prisutnost dodatnih i malih aneurizama parametri su koji su uspoređivani dvama protokolima. Rezultati: Metodom 3D tehnike detektirane su 54 aneurizme, dok je DSA metodom detektirano 38 aneurizama. U detekciji aneurizme i njezinog vrata između dviju metoda nije zabilježena statistički značajna razlika, ali je zabilježena razlika u uspješnosti u detekciji ovisno o korištenoj metodi. Statistički značajna pozitivna povezanost zabilježena je u određivanju veličine aneurizme između konvencionalne DSA
