Single cases of pericallosal posttraumatic and postsurgical aneurysms were previously reported. Herein, we report the first confirmed case of iatrogenic pericallosal artery aneurysm caused by an arterial wall injury during the endovascular treatment of another aneurysm.&lt;br \/&gt;\nA\u00a050-year-old woman with ruptured anterior communicating artery aneurysm was initially treated with balloon-assisted coiling. During the procedure the tip of a\u00a0microwire inserted into balloon catheter placed in the pericallosal artery caused a\u00a0local injury of the inner layer of the vessel wall and vasoconstriction, without bleeding, dissection, or flow disturbances visible in digital subtraction angiography (DSA). Control examination revealed dissecting peri\u00adcallosal aneurysm. After standard dual-antiplatelet oral preparation, stent-assisted coiling of the pericallosal artery aneurysm was performed with residual contrast filling of the base of the aneurysm sac in control angiography (RROC III). After 6 months the control DSA examination showed entirely cured pericallosal aneurysm (RROC I) and reconstruction of the parent artery.&lt;br \/&gt;\nSuccessful endovascular treatment of an iatrogenic pericallosal aneurysm was previously reported, and this method seems to be the first-choice treatment. In our case, endovascular stent-assisted coiling also allowed for safe exclusion from circulation of pericallosal dissecting aneurysm, and the implanted stent caused reconstruction of the parent artery, restoring the normal lumen diameter. The second endovascular treatment option considered was implantation of a\u00a0flow-diverted stent into the pericallosal artery.<\/jats:p>","DOI":"10.5114\/pjr.2021.103238","type":"journal-article","created":{"date-parts":[[2021,2,2]],"date-time":"2021-02-02T12:22:32Z","timestamp":1612268552000},"page":"50-52","source":"Crossref","is-referenced-by-count":4,"title":["Iatrogenic pericallosal artery aneurysm after endovascular procedure"],"prefix":"10.5114","volume":"86","author":[{"given":"Pawe\u0142","family":"Brzegowy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katarzyna","family":"Ciuk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bart\u0142omiej","family":"\u0141asocha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osit","family":"Chukwu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Borys","family":"Kwinta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrzej","family":"Urbanik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadeusz J.","family":"Popiela","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3061","published-online":{"date-parts":[[2021,1,18]]},"reference":[{"key":"ref-1150877","doi-asserted-by":"crossref","first-page":"626","DOI":"10.1016\/S1474-4422(11)70109-0","article-title":"Prevalence of unruptured intracranial aneurysms, with emphasis on sex, age, comorbidity, country, and time period: a systematic review and meta-analysis","volume":"10","author":"Vlak MH","year":"2011","unstructured":"Vlak MH, Algra A, Brandenburg R, et al.
