Key result
Interstitial laser occlusion of the vitelline artery and umbilical vein in two early pregnancies with twin reversed arterial perfusion sequence resulted in the birth of healthy babies at term.
Why the study?
Does interstitial laser treatment result in successful pregnancy outcomes in early gestation pregnancies complicated by twin reversed arterial perfusion sequence?

Does interstitial laser treatment result in successful pregnancy outcomes in early gestation pregnancies complicated by twin reversed arterial perfusion sequence?
Interstitial laser may be a feasible and effective treatment for twin reversed arterial perfusion sequence in early gestation.
May support early interstitial laser in TRAP sequence; leaves open confirmation in prospective studies.
Current treatments for twin reversed arterial perfusion sequence are associated with significant morbidity and most are not feasible in early gestation. We report the use of an interstitial laser in two pregnancies complicated by this sequence at 14 and 15 weeks, respectively. A 600 microm laser fibre was introduced via a 17 gauge needle into the abdomen of the perfused twin close to the vitelline artery and umbilical vein, which were occluded by neodymium:yttrium aluminium garnet (Nd:YAG) laser. Both pregnancies continued uneventfully and each resulted in the birth of a healthy baby at term.

Jolly et al. (2001) conducted a case report in Twin reversed arterial perfusion sequence (n=2). Interstitial laser (Nd:YAG) was evaluated on Birth of a healthy baby at term. Interstitial laser occlusion of the vitelline artery and umbilical vein in two early pregnancies with twin reversed arterial perfusion sequence resulted in the birth of healthy babies at term.
