Ultrasound Doppler scan revealed a large left iliofemoral deep vein thrombosis and the patient was diagnosed with phlegmasia cerulea dolens. After 24\u2009hours of treatment with unfractionated heparin, there were minimal improvements in her symptoms. Catheter-directed thrombolysis was performed, following multidisciplinary consultation with the patient. An underlying May-Thurner lesion was identified and successfully stented. Radiation exposure to the fetus was minimised with the use of intravenous ultrasound and very low-dose fluoroscopy. Total radiation exposure to the fetus is 1.38 mGy, which is equivalent to 8 months of background radiation exposure. No immediate complication occurred and patient\u2019s symptoms completely resolved. On further follow-up, her iliofemoral veins remained patent with good flow and there were no recurrence of symptoms. A healthy infant was successfully delivered at 40 weeks gestation.<\/jats:p>","DOI":"10.1136\/bcr-2017-223105","type":"journal-article","created":{"date-parts":[[2018,2,27]],"date-time":"2018-02-27T14:43:33Z","timestamp":1519742613000},"page":"bcr-2017-223105","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Should catheter-directed thrombolysis be the standard of care for pregnancy-related iliofemoral deep vein thrombosis?"],"prefix":"10.1136","volume":"2018","author":[{"given":"Tze Hung","family":"Siah","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Chapman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,2,27]]},"reference":[{"key":"2025042702564686000_2018.feb26_1.bcr-2017-223105.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2005.11.008"},{"key":"2025042702564686000_2018.feb26_1.bcr-2017-223105.2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-143-10-200511150-00006"},{"key":"2025042702564686000_2018.feb26_1.bcr-2017-223105.3","doi-asserted-by":"publisher","DOI":"10.1503\/cmaj.091692"},{"key":"2025042702564686000_2018.feb26_1.bcr-2017-223105.4","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-149-10-200811180-00004"},{"key":"2025042702564686000_2018.feb26_1.bcr-2017-223105.5","unstructured":"National Institute for Clinical Excellence.
