This is a retrospective study from a single center involving 255 examinations. The proposed median values (P50) for thrombectomy are: 123\u00a0Gy.cm2 for air kerma-area product (PKA) and 915\u00a0mGy for air kerma (Ka,r). For middle cerebral artery (MCA) thrombectomies, the proposed DRLs are 118\u00a0Gy.cm2 for PKA and 112\u00a0Gy.cm2 for internal carotid artery (ICA). The Ka,r values for MCA and ICA are 849 and 775\u00a0mGy, respectively. It was observed that 94.9% of patients presented grade 0 on the initial modified treatment in cerebral infarction (mTICI) scale, and after thrombectomy, 63.1% of patients reached a final mTICI grade of 3. Stents were implanted in 37 patients (14.5% of cases). It was concluded that 16.1% of patients exceeded one trigger value of the Safety in Radiological Procedures' recommended parameters. Establishing DRLs is an important tool for optimizing practices and is considered a standard for quality control.<\/jats:p>","DOI":"10.1093\/rpd\/ncae200","type":"journal-article","created":{"date-parts":[[2024,10,7]],"date-time":"2024-10-07T08:59:54Z","timestamp":1728291594000},"page":"1911-1917","source":"Crossref","is-referenced-by-count":1,"title":["Establishment of typical values in cerebral thrombectomy according to the stroke anatomical region and procedure clinical outcome"],"prefix":"10.1093","volume":"200","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-5038-6415","authenticated-orcid":false,"given":"Rog\u00e9rio","family":"Lopes","sequence":"first","affiliation":[{"name":"Unidade Local de Sa\u00fade de Gaia e Espinho , Rua Concei\u00e7\u00e3o Fernandes s\/n, 4434-502 Vila Nova de Gaia ,","place":["Portugal"]},{"name":"Faculdade de Engenharia da Universidade do Porto, Universidade do Porto , Rua Dr Roberto Frias, s\/n, 4200-465 Porto ,","place":["Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joana","family":"Santos","sequence":"additional","affiliation":[{"name":"Medical Imaging and Radiotherapy, Instituto Polit\u00e9cnico de Coimbra, ESTESC \u2013 Coimbra Health School , Rua 5 de Outubro, S.
