Maternal-fetal surgery for treatment of myelomeningocele

Ethical considerations of maternal-fetal surgery

The practice of maternal-fetal surgery (MFS) has expanded from lethal fetal conditions to conditions which are significantly disabling but not a lethal fetal abnormality. The inclusion of myelomeningocele within the scope of MFS in the 1990s sparked a renewed debate over the ethics of MFS. While demonstrating increasing efficacy and range of application, MFS continues to be ethically fraught due to the inherent tension between maternal and fetal interests. Ethical issues central to MFS include the patienthood of the fetus; the balance of risks and benefits between the woman and fetus; informed consent for experimental procedures; and determination of conditions that meet ethical qualifications for MFS intervention. These concerns are likely to persist and evolve as perinatal medicine continues to advance. Here we summarize the current state of MFS ethics, highlighting the major positions in the literature thus far as well as examine future directions. It is essential robust discussions of these important issues continue both to ensure ethical medical practice and to provide support to clinicians, pregnant women, and their families.

Attitudes of paediatric and obstetric specialists towards prenatal surgery for lethal and non-lethal conditions

BACKGROUND

While prenatal surgery historically was performed exclusively for lethal conditions, today intrauterine surgery is also performed to decrease postnatal disabilities for non-lethal conditions. We sought to describe physicians' attitudes about prenatal surgery for lethal and non-lethal conditions and to elucidate characteristics associated with these attitudes.

METHODS

Survey of 1200 paediatric surgeons, neonatologists and maternal-fetal medicine specialists (MFMs).

RESULTS

Of 1176 eligible physicians, 670 (57%) responded (range by specialty, 54%-60%). In the setting of a lethal condition for which prenatal surgery would likely result in the child surviving with a severe disability, most respondents either disagreed (59%) or strongly disagreed (19%) that they would recommend the surgery. Male physicians were twice as likely to recommend surgery for the lethal condition, as were physicians who believe that abortion is morally wrong (OR 1.75; 95%CI 1.0 to 3.05). Older physicians were less likely to recommend surgery (OR 0.57; 95%CI 0.36 to 0.88). For non-lethal conditions, most respondents agreed (66% somewhat, 4% strongly) that they would recommend prenatal surgery, even if the surgery increases the risk of prematurity or fetal death. Compared with MFMs, surgeons were less likely to recommend such surgery, as were physicians not affiliated with a fetal centre, and physicians who were religious (ORs range from 0.45 to 0.64).

CONCLUSION

Physician's attitudes about prenatal surgery relate to physicians' beliefs about disability as well as demographic, cultural and religious characteristics. Given the variety of views, parents are likely to receive different recommendations from their doctors about the preferable treatment choice.

The experience of parents with children with myelomeningocele who underwent prenatal surgery

BACKGROUND

Prenatal surgery for myelomeningocele (MMC) has been demonstrated to have benefits over postnatal surgery. Nevertheless, prenatal surgery requires a significant emotional, physical, and financial commitment from the entire family.

METHODS

Mixed methods study of parents' perceptions regarding provider communication, treatment choices, and the family impact of having a child with MMC.

RESULTS

Parents of children with MMC (n= 109) completed questionnaires. Parents were well informed and reported gathering information about prenatal surgery from a wide range of sources. After a fetal diagnosis of MMC, most learned about their options from their obstetrician, although one-third were not told about the option of prenatal surgery. About one-fourth of these parents felt pressure to undergo one particular option. Half of parents said that having a child with MMC has had a positive impact on them and their family, while the other half indicated that having a child with MMC has had both positive and negative impacts. The most commonly noted positive impacts were changes in parental attitudes, as well as having new opportunities and relationships. The most frequently reported negative impacts concerned relational and financial strain. The vast majority of parents indicated that they would still undergo prenatal surgery if they could travel back in time with their present knowledge.

CONCLUSIONS

A better understanding of the parental experiences and perspectives following prenatal surgery will play an important role in providing overall support for parents and family members.

Ethical challenges in the new world of maternal-fetal surgery

This article explores some of the complex ethical challenges that exist in the field of fetal diagnosis and treatment, especially surrounding maternal-fetal surgery. The rise of these new treatments force us to reconsider who or what is the fetus, what are our obligations to the fetus, and what are the limits to those obligations. In addition, we will consider provider and professional biases, disability issues, and how maternal-fetal surgery has, for a select group of women, changed the very experience of motherhood.

Ethics: "life before birth" and moral complexity in maternal-fetal surgery for spina bifida

This article considers the ethical significance of a moral belief common among pregnant women (and their partners) who seek open uterine repair for fetal spina, namely that their fetuses are already "babies." The need to recognize and interact sensitively with a pregnant woman's vulnerability to her own beliefs and concerns regarding potential disabilities, the fetal intervention, and its potential outcome is emphasized. Such recognition and explicit discussions are ethically important for informed consent and to safeguard against the judgments, enthusiasms, and biases of surgeons and other team members.
