Ovarian Hyperstimulation Syndrome (OHSS) Presented as Massive Hydrothorax

Imaging of complications following treatment with assisted reproductive technology: keep on your radar at each step

Since the advent of assisted reproductive technology (ART), the utilization of ART procedures has become increasingly popular among women seeking to establish pregnancy. Radiologists are therefore likely to encounter the various complications of ART therapy. The most common is ovarian hyperstimulation syndrome; others are multiple, ectopic, and heterotopic pregnancies. Ultrasonography is considered the initial modality to investigate ART complications, However, nonspecific symptoms might need the use of an additional imaging modality, such as computed tomography or magnetic resonance imaging, as a problem-solving tool. This article briefly discusses the steps involved in assisted reproduction. Its aim is to help radiologists become familiarized with the multimodality imaging features of the spectrum of ART-related complications. Their key imaging features and differential considerations are emphasized. This will facilitate the provision of precise and timely diagnoses, and aid the avoidance of fatal consequences.

Diagnostic Complexities in a Case of Ovarian Hyperstimulation Syndrome Presented Solely as a Unilateral Massive Hydrothorax

To describe a rare case of unilateral massive hydrothorax after controlled ovarian stimulation for IVF and to analyze the diagnostic complexities in a patient lacking both risk factors and typical features of ovarian hyperstimulation syndrome (OHSS). We present a case of a 35-year-old woman suffering from primary infertility due to a severe male factor. Admitted to hospital for dyspnea, the patient initially underwent a thoracentesis. Later, due to the recurrence of massive hydrothorax, permanent pleural drainage was placed. Recognized as a severe manifestation of the OHSS, it was treated by pleural drainage, hydration, albumin perfusion, and management of the intercurrent pregnancy, up to improvement in clinical and hematological laboratory parameters and resolution of pleural effusion and respiratory symptoms. A total of 42 l of pleural fluid was drained during the 40 days of hospitalization. Since the pathogenesis of isolated acute hydrothorax in ovarian stimulation probably lies in the presence of anatomical defects of the diaphragm, this may justify that the relationship between this pathology and the OHSS risk factors may be less close. Massive pleural effusion may exceptionally be the only clinical presentation of OHSS. A high index of suspicion is necessary to make the correct diagnosis and to promptly administer treatment.

Effect of Bushen Yutai Recipe on IVF Patients Subjected to Mild Ovarian Stimulation

This article investigated the effects of the traditional Chinese medicine (TCM) herbal recipe, Bushen Yutai, on in vitro fertilization (IVF) patients subjected to mild ovarian stimulation. Two hundred nineteen infertile patients were randomly divided into 2 groups: the control group and herbal treatment group. By studying, we found estrogen levels (E₂) on the human chorionic gonadotropin (hCG) triggering day were significantly lower in the control group (P < 0.05), with positive blood flow being less detected by ultrasound scanning on both the day of hCG triggering and day of fresh embryo transfer for the control group (P < 0.05). Additionally, the blood flow index, retroactive and proactive inhibition, was higher in the control group, whereas the fertilization rate and number of high-quality embryos in the control group were lower than the control TCM experimental group (P < 0.01). The expression levels of the endometrial receptivity gene, vascular endothelial growth factor (VEGF), were lower in the control group vs. the TCM experimental group on the day of fresh embryo transfer (P < 0.05), whereas the rate of fresh embryo transfer in the control group was lower than the TCM experimental group (P < 0.05). In conclusion, the TCM could increase the E₂ during the IVF stage, with a higher number of oocytes and higher-quality embryos. It also improved the endometrium and increased the level of VEGF gene expression. By enhancing the fresh embryo transfer rate in a minimal ovarian stimulation protocol and by improving the clinical pregnancy and ongoing pregnancy rates, the Bushen Yutai recipe could be able to increase fresh embryo transfer and higher-quality embryos.

Potential imaging findings following assisted reproduction: complications and clinical implications

Recent rapid advances in assisted reproduction (ART) have led to global increase in usage of in vitro fertilization. This in turn has resulted in clinicians and imaging specialists encountering increase in complications associated with ART. The specialists dealing with infertility should be aware of potential complications associated with ART. Early diagnosis of these problems is based on clinician's suspicion and radiologist's awareness of these complications. Many of these conditions may be life threatening. Hence, early diagnosis and treatment of these complications can safeguard the fetal and maternal health.
