No cases have described injury to only the small vessels of the feet. We present a case of a 20\u2010year\u2010old male presenting with painful dusky digits of both feet who was initially thought to have a small\u2010vessel vasculitis, but instead found on histopathological examination to have acute thrombotic vasculopathy causing cutaneous ischaemia. He was subsequently found to have a patent foramen ovale (PFO) but no thrombosis elsewhere. This case underscores the importance of transthoracic echocardiography (TTE) in patients presenting with small\u2010vessel ischaemia, even in the absence of deep venous thromboses.<\/jats:p>","DOI":"10.1155\/crrh\/8840496","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T09:18:30Z","timestamp":1741684710000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Small\u2010Vessel Thrombotic Vasculopathy Secondary to Paradoxical Emboli Traversing a Patent Foramen Ovale: A Vasculitis Mimic"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-9999-1947","authenticated-orcid":false,"given":"Trevor","family":"Kwan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven","family":"Tu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1159-2323","authenticated-orcid":false,"given":"Carlos","family":"El-Haddad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,2,26]]},"reference":[{"key":"e_1_2_12_1_2","volume-title":"Paradoxical Embolism","author":"Hakman E.
