Spontaneous intrauterine pregnancy after unilateral placement of tubal occlusive microinsert

Objective: To present a case in which the use of a titanium/nickel microinsert in the management of unilateral hydrosalpinx contributed to a spontaneous intrauterine pregnancy. Design: Case report. Setting: University hospital. Patient(s): A 37-year-old nulligravid female with dense pelvic adhesive disease and unilateral hydrosalpinx. Intervention(s): Unilateral proximal occlusion of left fallopian tube with titanium/nickel microinsert. Main Outcome Measure(s): Pregnancy. Result(s): Spontaneous intrauterine pregnancy after confirmation via hysterosalpingogram of left tubal occlusion and right tubal patency. Conclusion(s): Transcervical proximal tubal occlusion using titanium/nickel microinserts provides an alternative in the management of hydrosalpinx in the setting of tubal factor infertility. Additionally, in the setting of a unilateral hydrosalpinx, unilateral occlusion can contribute to spontaneous intrauterine pregnancy.
