Transvaginal sonography (TVS)-guided oocyte retrieval is an assisted reproductive technology commonly performed for in vitro fertilization. This report presents the case of a 42-year-old primigravida, who presented in the second trimester of pregnancy with vaginal bleeding and left iliac fossa pain. Magnetic resonance imaging and TVS revealed a pseudoaneurysm in the left parametrium. To avoid radiation exposure to the fetus, TVS-guided embolization was planned for the patient. Under TVS guidance, a Chiba needle was advanced into the pseudoaneurysm sac, and lyophilized thrombin powder reconstituted in calcium chloride solution was injected. Immediate thrombosis of the pseudoaneurysm was observed. Her abdominal pain reduced after the procedure, and she did not have any further episodes of vaginal bleeding. Follow-up TVS performed after one month showed persistent occlusion of the pseudoaneurysm.
经阴道超声引导下取卵是一种常用于体外受精的辅助生殖技术。本报告介绍了一名42岁初产妇的病例，该患者在妊娠中期出现阴道出血和左髂窝疼痛。磁共振成像和经阴道超声显示左侧子宫旁有一个假性动脉瘤。为避免胎儿受到辐射，计划对该患者进行经阴道超声引导下栓塞术。在经阴道超声引导下，将一根千叶针推进到假性动脉瘤囊内，并注入用氯化钙溶液复溶的冻干凝血酶粉。观察到假性动脉瘤立即形成血栓。术后她的腹痛减轻，且未再出现阴道出血情况。一个月后进行的随访经阴道超声显示假性动脉瘤持续闭塞。
