Özet

Minimal İnvaziv Ekstrakorporeal Dolaşım (MiECC) sistemleri, konvansiyonel kardiyopulmoner bypass ile ilişkili hemodinamik bozuklukları, sistemik inflamatuar yanıtı ve perioperatif komplikasyonları azaltmak amacıyla geliştirilmiş ileri düzey perfüzyon teknolojileridir. Kapalı devre, heparin kaplı ve miniatürize tasarıma sahip olan MiECC, venöz rezervuar içermez, priming hacmini minimize eder ve kanın yapay yüzeylerle temasını azaltarak sistemik inflamatuar yanıtın kontrolünü sağlar. Ayrıca, optimize edilmiş devre tasarımı perioperatif hematokrit seviyelerinin korunmasına, oksijen taşıma kapasitesinin sürdürülmesine ve transfüzyon gereksiniminin azalmasına katkıda bulunur.

MiECC’de kullanılan teknik iyileştirmeler arasında yalnızca kanla temas halinde aktive olan aspirasyon sistemleri, postoperatif ototransfüzyon için hücresel kan geri kazanım (cell saver) sistemleri ve modüler devre tasarımları öne çıkar. Klinik çalışmalar ve meta-analizler, MiECC kullanımının postoperatif morbiditeyi azalttığını, böbrek ve miyokard fonksiyonunu koruduğunu ve inflamatuar belirteçlerde düşüş sağladığını göstermektedir. Kapalı devre ve düşük priming hacmi sayesinde heparin ihtiyacı azalmakta, kanama riski minimize edilmekte ve hasta güvenliği artmaktadır. Bu derlemede, MiECC sistemlerinin teknik özellikleri, uygulama yöntemleri ve klinik avantajları güncel araştırma bulguları ışığında ayrıntılı şekilde ele alınmış, kardiyak cerrahideki potansiyel rolü ve faydaları vurgulanmıştır.
