Materials and Methods: Retrospective analysis of the distance of the tip of the microcatheter from coiled or patent non-target arteries was measured during 99mTc-MAA work-up procedure. Frequency of extrahepatic leaking during work-up and SIRT procedures was evaluated. Results: There were 85 patients who underwent 98 work-up procedures. There were 64 radioembolizations. There were 44 gastroduodenal, 51 right gastric, and 54 cystic artery embolizations performed. Extrahepatic 99mTc-MAA leaking was observed in 33 cases: 16 to gallbladder, four to a gastric wall, nine to the duodenum, one to the intestinal wall, and three to the abdominal wall. Leak in 99mTc-MAA was also related to the presence of additional arteries (p = 0.009). There were 34 proximal and 31 distal to cystic artery 99mTc-MAA injections resulting in 12 vs. four leaks, respectively (p = 0.039, RR-2.5). Mean distance of the tip of the microcatheter from the origin of the cystic artery was 20 mm (minimum of 2.1 mm and maximum of 53 mm) proximally and 10 mm (minimum 1 mm and maximum 51 mm) distally (ns). Conclusions: Leaking in 99mTc-MAA (99mTc - labelled macroaggregated albumin) was related to the presence of additional arteries. Regardless of cystic artery embolization, it is 2.5 times safer to inject microspheres distal to its origin, compared to proximal injection. Cystic artery origin relative to the right hepatic artery division usually necessitates embolization of the former.<\/jats:p>","DOI":"10.3390\/jcm8101531","type":"journal-article","created":{"date-parts":[[2019,9,25]],"date-time":"2019-09-25T03:51:18Z","timestamp":1569383478000},"page":"1531","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Gallbladder Radiation Protection in SIRT\u2014Quantitative Anatomical Study of Hepatic Vasculature"],"prefix":"10.3390","volume":"8","author":[{"given":"Piotr","family":"Piasecki","sequence":"first","affiliation":[{"name":"Department of Interventional Radiology, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krzysztof","family":"Brzozowski","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Ziecina","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marek","family":"Wierzbicki","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Budzynska","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Mazurek","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miroslaw","family":"Dziuk","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3842-6720","authenticated-orcid":false,"given":"Maciej","family":"Maciak","sequence":"additional","affiliation":[{"name":"National Centre for Nuclear Research, Andrzej Soltan 7, 05-400 Otwock, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward","family":"Iller","sequence":"additional","affiliation":[{"name":"National Centre for Nuclear Research, Radioisotope Centre POLATOM, Andrzej Soltan 7, 05-400 Otwock, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jerzy","family":"Narloch","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, Military Institute of Medicine, Szaser\u00f3w 128, 04-141 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104S","DOI":"10.2967\/jnumed.116.187229","article-title":"Radioembolization of Colorectal Liver Metastases: Indications, Technique, and Outcomes","volume":"58","author":"Boas","year":"2017","journal-title":"J.
