Distal Vaginal Atresia with Spontaneous Perforation: A Case Report

BACKGROUND

The definitive treatment of distal vaginal atresia is surgery, but menstrual suppression is often helpful for initial management.

CASE

A 13-year-old presented with primary amenorrhea and progressive abdominal pain. She was diagnosed with distal vaginal atresia and started on hormonal suppression. She then re-presented with heavy vaginal bleeding, and follow-up imaging revealed that spontaneous perforation had occurred. There was now evidence of a tract leading from the obstructed vaginal bulge to the introitus. Vaginoplasty was complicated by the tortuosity of the tract. Under ultrasound guidance, a pull-through vaginoplasty was performed.

SUMMARY AND CONCLUSION

Spontaneous perforation of an atretic vagina is rare, but in such cases, urgent vaginoplasty is indicated to prevent infection. Despite the presence of a spontaneous tract leading to the obstruction, vaginoplasty can be complex, and intraoperative ultrasound could be beneficial.

Multiple variants of obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome - one clinical center case series and the systematic review of 734 cases

INTRODUCTION

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare female urogenital tract malformation.

STUDY OBJECTIVE

To present 10 patients with OHVIRA treated at the clinical center. To perform a systematic review of OHVIRA case series related to the prevalence of anatomical variants, surgical interventions and endometriosis, and to compare them with our case series.

MATERIALS AND METHODS

Medical records from 10 OHVIRA patients treated between 2016 and 2020 were retrospectively reviewed. For the systematic review, PubMed and Web of Science were used to search for relevant studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were strictly followed.

RESULTS

The most common anatomical variant includes left obstructed hemivagina (50.7%) with isolated hematocolpos or hydrocolpos (55.9%), uterus didelphys (82.9%), and ipsilateral renal agenesis (92.2%). Vaginal septectomy was the most common surgical approach (86.5%). Hemivaginectomy (2.2%), hemihysterectomy (4.2%), or total hysterectomy (0.7%) were also performed in several patients. Some subjects required salpingectomy (3.3%) or oophorectomy (1.8%). 7.5% of patients, mainly infants, did not require surgery due to the spontaneous resolution of hydrocolpos. Endometriosis was fortuitously found in 13.6% of the selected cases who underwent laparoscopy or laparotomy.

DISCUSSION

The most common variant of OHVIRA includes isolated hematocolpos and a thick vaginal septum between adjacent hemivaginas. Endometriosis was present in approximately 14% of OHVIRA patients, but this number is probably underestimated. Routine laparoscopy is not required. However, all patients need further monitoring due to a higher risk of endometriosis. Based on the analyzed studies and our case series, vaginal septectomy is a sufficient surgical technique to relieve symptoms and prevent possible complications in most OHVIRA patients.
