Objective Donor demise after laser surgery for twin–twin transfusion syndrome (TTTS) is well‐characterized, but recipient demise is not, nor is neonatal death. This study aims to characterize factors associated with recipient death, donor death, and dual twin death after laser, both before and after birth. Methods This is a prospective cohort study of monochorionic twin pairs who underwent laser ablation for TTTS. Risk factors for fetal and neonatal death of both twins were identified using univariable analysis and recursive partitioning, a novel statistical method to quantify contributions of each factor to outcomes. Results In 413 twin pairs, death of both twins occurred in 9.2% (38/413), donor death in 12.1% (50/413), and recipient death in 2.4% (10/413). Recursive partitioning showed that gestational age at delivery predicts dual twin death (below 23.7 weeks, likely [p < 0.001], above 28.3 weeks, unlikely [p = 0.004]). Abnormal umbilical artery Doppler and weight discordance predict donor demise (p < 0.001 and p = 0.033, respectively). Cervical length under 16 mm predicts neonatal death of both twins (p < 0.001). Conclusions Parents can gain individualized information about the survival of each fetus based on variables available from preoperative and delivery variables. Short cervix and premature delivery cause significant mortality in TTTS.

Objective–Perinatal palliative care (PPC) is an option for patients who discover that their infant has a life-limiting fetal condition, which decreases the burden of the condition using a multidisciplinary approach. Study Design–This review discusses the landmark literature in the past two decades, which have seen significant growth and development in the concept of PPC. Results–The literature describes the background, quality, and benefits of offering PPC, as well as the ethical principles that support its being offered in every discussion of fetal life-limiting diagnoses. Conclusions–PPC shares a similar risk profile to other options after life-limiting diagnosis, including satisfaction with choice of continuation of pregnancy. The present clinical opinion closes by noting common barriers to establishing PPC programs and offers a response to overcome each one. Key Points
