RESUMO
Introduction: Cervix atresia causing hematometra usually presents at puberty with cyclic abdominal pain. The management depends upon the type and severity of cervix atresia. We present a novel technique of managing a case of cervix atresia in a 13 years old girl. Case report: A 13 years old girl presented with severe cyclic abdominal pain. Examination revealed normal external genitalia with a palpable tender mass in the suprapubic area. Ultrasonography and MRI suggested a large hematometra with a 1.5 cm long cervix atresia. Vaginoscopy performed under anesthesia showed a normal-looking vagina and a blind cervix. During vaginoscopy and dynamic ultrasound (US) guidance, a spinal needle was passed through the vagina and center of the atretic cervix into the uterine cavity containing the hemolyzed blood. Aspiration of the hemolyzed blood and US visualization confirmed the location of the needle in the uterine cavity. A three-stage (esophageal) balloon dilator was passed over a guidewire through the atretic area. The balloon dilator was dilated up to 10 mm using pressure-controlled dilatation. A satisfactory dilatation was achieved, and all the retained hemolyzed blood was drained through the newly created channel. A size 24 Foleys catheter was retained in the uterine cavity and removed after 1 week. A repeat ultranography before subsequent periods showed a recurrent collection and obliteration of the cervix. US-guided balloon dilatations were repeated. A third dilatation was required after an interval of few months. The child remained well after the third dilatation, having regular periods, and is symptom free at 8 months follow-up, however, may need more sessions of cervix dilatations. Conclusion: Genitoscopic US-guided cervix fenestration and balloon dilatation is an effective technique for treatment of cervix atresia. It is a safe technique, avoids major surgical reconstructions, is a minimally invasive procedure, and can be used in selected cases of cervix atresia.
