The objective of this retrospective cohort study is to analyze the association between VW-CE and perioperative acute ischemic stroke (PAIS) occurring within 24 h after revascularization. Methods: All previously untreated MMD patients who required revascularization and who had undergone preoperative MRI with VW-CE-sequences were included. PAIS was detected by CT and\/or diffusion-weighted MRI sequences within 24 h postoperatively. Results: Of the 110 patients included (female-to-male ratio: 2.7:1, median age: 45.1 (16.6\u201369.2); n = 247 revascularizations), a priori VW-CE was present in 67.3% (mean time from MRI to first surgery: 86 days \u00b1 82 days). PAIS occurred in five patients undergoing primary revascularization (PAIS rate per revascularization: 2.1%), all of whom had a preoperative pathological VW-CE in the vascular segment corresponding to the stroke area. Two (40%) incidents of PAIS occurred in revascularized territory, while three (60%) occurred in non-revascularized vascular territory. In each case, the supplying artery exhibited VW-CE, indicating disease activity. No additional PAIS occurred during subsequent revascularizations in cases of multistage procedures (n = 38), such as ACA or PCA revascularization as a second step. Conclusions: Preoperative VW-CE in one or more vascular segments may be a marker for postoperative stroke in the respective vascular territory at the time of revascularization. VW-CE imaging should be routinely performed when planning revascularization in MMD. If VW-CE is found, strict perioperative monitoring of these high-risk patients should be performed to achieve the best results possible.<\/jats:p>","DOI":"10.3390\/brainsci14121190","type":"journal-article","created":{"date-parts":[[2024,11,27]],"date-time":"2024-11-27T04:20:12Z","timestamp":1732681212000},"page":"1190","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Coincidence of Concentric Vessel-Wall Contrast Enhancement in Moyamoya Disease and Acute Postoperative Ischemic Stroke During Revascularization Procedures"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7728-2091","authenticated-orcid":false,"given":"Patrick","family":"Haas","sequence":"first","affiliation":[{"name":"Department of Neurosurgery and Moyamoya Center, University of T\u00fcbingen, Hoppe-Seyler-Stra\u00dfe 3, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7604-3419","authenticated-orcid":false,"given":"Till-Karsten","family":"Hauser","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University of T\u00fcbingen, Hoppe-Seyler-Stra\u00dfe 3, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucas Moritz","family":"Wiggenhauser","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Moyamoya Center, University of T\u00fcbingen, Hoppe-Seyler-Stra\u00dfe 3, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4105-5131","authenticated-orcid":false,"given":"Leonie","family":"Zerweck","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, University of T\u00fcbingen, Hoppe-Seyler-Stra\u00dfe 3, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcos","family":"Tatagiba","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Moyamoya Center, University of T\u00fcbingen, Hoppe-Seyler-Stra\u00dfe 3, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadia","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Moyamoya Center, University of T\u00fcbingen, Hoppe-Seyler-Stra\u00dfe 3, 72076 T\u00fcbingen, Germany"},{"name":"Moyamoya Center, University Children\u2019s Hospital Zurich, University of Zurich, Steinwiesstrasse 75, 8032 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4487-2807","authenticated-orcid":false,"given":"Constantin","family":"Roder","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Moyamoya Center, University of T\u00fcbingen, Hoppe-Seyler-Stra\u00dfe 3, 72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"340","DOI":"10.1016\/j.jstrokecerebrovasdis.2015.10.003","article-title":"Effects of Surgery and Antiplatelet Therapy in Ten-Year Follow-Up from the Registry Study of Research Committee on Moyamoya Disease in Japan","volume":"25","author":"Yamada","year":"2016","journal-title":"J.
