Pelvic arteriovenous fistula (AVF) is a rare vascular malformation that is most commonly congenital, post-traumatic, or iatrogenic. The link between leiomyomatosis and AVF has received little attention in the medical literature.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We provide a case series of seven patients, four of whom were from our center, who had IVL complicated by a pelvic AVF. The symptoms of right heart failure were noted as swelling in the abdomen and two legs as well as a significant amount of ascites. Coil embolization of AVFs may be beneficial in minimizing bleeding during IVL surgery. A review of all accessible literature published on IVLs from 2000 to 2020 was conducted, and data were retrieved from 78 papers totaling 262 cases. Complications and recurrence were associated with pelvic mass excision and intravascular remnant tumor, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Intravenous leiomyomatosis combined with AVF aggravates congestion symptoms of surrounding organs. It is worth noting the uncommon combination of AVF and IVL, stressing the importance of a thorough assessment and surgical approach in IVL treatment.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcvm.2022.878386","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T06:11:58Z","timestamp":1655100718000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Intravenous Leiomyomatosis Complicated by Arteriovenous Fistula: Case Series and Literature Review"],"prefix":"10.3389","volume":"9","author":[{"given":"Haoxuan","family":"Kan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuexin","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuehong","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,6,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"987","DOI":"10.1016\/0741-5214(94)90237-2","article-title":"Intravenous leiomyomatosis","volume":"20","author":"Grella","year":"1994","journal-title":"J Vasc Surg."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1240","DOI":"10.1016\/j.humpath.2010.10.015","article-title":"Intravenous leiomyomatosis of the uterus: a clinicopathologic study of 18 cases, with emphasis on early diagnosis and appropriate treatment strategies","volume":"42","author":"Du","year":"2011","journal-title":"Hum Pathol."},{"key":"B3","doi-asserted-by":"publisher","first-page":"e145","DOI":"10.1016\/j.athoracsur.2016.07.037","article-title":"Intracardiac Extension of Intravenous Leiomyomatosis","volume":"103","author":"Price","year":"2017","journal-title":"Ann Thorac Surg."},{"key":"B4","doi-asserted-by":"publisher","first-page":"91","DOI":"10.1016\/j.ijcard.2016.08.140","article-title":"A rare cause of intracardiac mass","volume":"223","author":"Caldentey","year":"2016","journal-title":"Int J Cardiol."},{"key":"B5","doi-asserted-by":"publisher","first-page":"9758302","DOI":"10.1155\/2020\/9758302","article-title":"Intravenous Leiomyomatosis of the Uterus: A Retrospective Single-Center Study in 14 Cases","volume":"2020","author":"Su","year":"2020","journal-title":"Biomed Res Int."},{"key":"B6","doi-asserted-by":"publisher","first-page":"e16","DOI":"10.1161\/CIRCULATIONAHA.108.826107","article-title":"Images in cardiovascular medicine.
