Abstract

Özet
Twin reversed arterial perfusion" (TRAP) sekansı monokoryonik ikiz gebeliklerde nadir görülen bir durumdur. Görülme insidansı 1:35,000 olup, tüm monokoryonik gebeliklerin yaklaşık %1'inde görülebilir. Etyopatogenetik mekanizması tam olarak bilinmemektedir. Normal bir donör ikiz ve bir akardiyak alıcı ikiz birlikte bulunmaktadır. Olgu sunumumuzda 22 yaşında nullipar 23.gestasyonel haftada ultrasonografik olarak tanı konulan TRAP sekansını rapor ettik. TRAP sekansı prognozu akardiak ikiz için ölümcül olup, donör ikizde de konjestif kalp yetmezliği gelişmesi durumunda mortalite oldukça yüksektir. Kadın Hastalıkları ve Doğum uzmanları ikiz/çoğul gebeliklerde TRAP sekansına karşı dikkatli olmalıdır.

Abstract
Twin reversed arterial perfusion (TRAP) sequence is a rare condition of monochorionic twin pregnancy. It has an incidence of 1:35.000 pregnancies and consists of 1 % all monochorionic pregnancies. The ethiopathogenetic mechanisms are not well defined. There is co-existence of a normal pump twin and an acardiac recipient twin. A 22-year-old nulliparous woman was referred with twin reversed arterial perfusion (TRAP) sequence. The prognosis in TRAP sequence is lethal for acardiac twin and the fetal mortality of the pump twin is very high due to the cardiac failure. The obstetrician should be aware of TRAP-sequence in twin/ multiple pregnancies.
