Radiation Dose and Fluoroscopy Time of Endovascular Treatment in Patients with Intracranial Lateral Dural Arteriovenous Fistulae

Abstract: Purpose Intracranial lateral dural arteriovenous fistula (LDAVF) represents a specific subtype of cerebrovascular fistulae, harboring a potentially life-threatening risk of brain hemorrhage. Fluoroscopically guided endovascular embolization is the therapeutic gold standard. We provide detailed dosimetry data to suggest novel diagnostic reference levels (DRL). Methods Retrospective single-center study of LDAVFs treated between January 2014 and December 2019… Show more

“…Data on radiation exposure of other neuroradiological procedures re-main scarce and to our knowledge no data have been published for CCF embolization. The local DRLs for CCF embolization in our study (350 Gy cm 2 ) are substantially lower compared with published data on cranial AVM (DRL range 440-550 Gy cm 2 ) [24,25] and lateral dAVF embolization (DRL 414 Gy cm 2 ) [26], although comparison is difficult because of differences in anatomic location and endovascular treatment techniques.…”

“…The LD protocol yielded a dose reduction of 32.6%. The positive impact of this dedicated DSA protocol on radiation dose was also demonstrated in recently published papers from our institution [ 13 , 14 , 15 ].…”

“…Only in a few dosimetry studies, have intracranial DAFVs been represented as a subcategory [ 14 , 21 , 22 ]. The reported results in terms of local DRLs were quite various (414 Gy cm 2 , 507.33 Gy cm 2 and 730 Gy cm 2 ).…”
