SEZARYEN SKAR EKTOPİK GEBELİĞİ VE PLASENTA AKREATA SPEKTRUMUNDA ACİL YÖNETİM
Özet
ÖZET
Küresel sezaryen oranlarındaki sürekli artış, uterusun alt segmentindeki skar dokusuna bağlı yerleşim bozukluklarını obstetrik aciller içinde giderek daha görünür bir sorun hâline getirmiştir. Sezaryen skar gebeliği ve plasenta akreata spektrumu, uzun süre birbirinden bağımsız iki tablo olarak ele alınmış olsa da, güncel histopatolojik ve sonografik veriler bunların aynı iatrojenik sürecin birinci ve üçüncü trimesterdeki görünümleri olduğunu ortaya koymaktadır. Bu bölümde skar defekti ve desidualizasyon yetmezliği temelindeki patogenez, standartlaştırılmış ultrasonografik tanımlayıcılara dayalı antenatal tanı, prenatal evreleme sistemleri ve FIGO 2019 klinik sınıflandırması eleştirel biçimde ele alınmaktadır. Bölümün ağırlık merkezini, acil koşullarda karşılaşılan üç senaryo oluşturmaktadır: kanayan veya rüptüre sezaryen skar gebeliği, antenatal tanı almış olguda erken kanama ya da doğum eylemi ve beklenmedik intraoperatif karşılaşma. Her senaryo için basamaklı bir yönetim çerçevesi sunulmakta; masif transfüzyon protokolleri, profilaktik balon oklüzyonuna ilişkin çelişkili randomize kanıtlar ve uterus koruyucu yaklaşımların gerçekçi başarı oranları tartışılmaktadır. Bölüm, sonuçları en çok iyileştiren değişkenin cerrahi tekniğin ayrıntısı değil, önceden yazılmış bir doğum planı ile tanımlı bir multidisipliner ekip olduğu savıyla kapanmaktadır.
Anahtar Kelimeler: Sezaryen skar gebeliği, plasenta akreata spektrumu, obstetrik kanama, sezaryen histerektomi, antenatal tanı.
