Treatment of twin reversed arterial perfusion sequence by septostomy and amniodrainage: a case report

Abstract

This case presented it demonstrate favorable development of the gestation, with labor happening at 35 weeks gestation and pump twin presenting good vitality conditions. In cases with no major factors of bad prognosis, septostomy combined with amniodrainage could be an interesting therapeutic option for a safe and efficacious management of selected cases of TRAP sequence.

Acardia: Epidemiologic findings and literature review from the International Clearinghouse for Birth Defects Surveillance and Research

“…Although the prevalence of malformations is not strikingly high, the consistency of the malformation type with what has been described in the literature is noteworthy. Regardless of structural malformations, the co‐twin has significantly increased prenatal and perinatal mortality, due mainly to heart failure and cardiomegaly secondary to the co‐twin's function as the “pump.” Mortality continues to be high to this day, 30–50% or more, particularly if the acardiac twin is comparatively large [Sullivan et al, 2003; Tanawattanacharoen et al, 2004; Guimaraes Filho et al, 2007; Gupta et al, 2008; Chandramouly and Namitha, 2009; He et al, 2010; Lewi et al, 2010]. When the acardiac twin is comparatively smaller, survival rates of the co‐twin could be higher [Jelin et al, 2010; Lewi et al, 2010].…”
