In eight cases, the balloon catheter was placed immediately following local and\/or <jats:styled-content style=\"fixed-case\">IM MTX<\/jats:styled-content> treatment, either because of bleeding or prophylactically; in eight cases, the catheter was placed as part of a two\u2010step protocol, with patients first treated with local and <jats:styled-content style=\"fixed-case\">IM MTX<\/jats:styled-content> injection, then suction aspiration on Day 4 or 5, followed by planned insertion of a balloon catheter; in one patient the balloon was placed on Day 21 after local and <jats:styled-content style=\"fixed-case\">IM MTX<\/jats:styled-content> treatment, due to sudden bleeding; and in one case of a heterotopic pregnancy, one intrauterine and one cervical, the balloon was placed due to severe bleeding. Human chorionic gonadotropin (<jats:styled-content style=\"fixed-case\">hCG<\/jats:styled-content>) levels were evaluated weekly following <jats:styled-content style=\"fixed-case\">MTX<\/jats:styled-content> injection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Gestational ages at balloon placement ranged between 5 and 12\u2009+\u20092\u2009weeks. All embryos\/fetuses, with the exception of the cervical heterotopic one, had heart activity and catheter placement was well\u2010tolerated by all women. The balloon tamponade effectively reduced or prevented maternal vaginal bleeding in all except one patient; this woman had a heterotopic <jats:styled-content style=\"fixed-case\">CxP<\/jats:styled-content> and required abdominal robotic cerclage to control the bleeding. Catheters were kept in place for a mean of 3.6 (range, 1\u20136) days. <jats:styled-content style=\"fixed-case\">hCG<\/jats:styled-content> levels returned to low or zero levels within 19\u201382 days following <jats:styled-content style=\"fixed-case\">MTX<\/jats:styled-content> injection.
