Radyolojide Kontrast Madde Güvenliği: Güncel Yaklaşımlar
Özet
Bu bölümde, 2020-2026 döneminde yayımlanan ACR ve ESUR başta olmak üzere güncel kılavuzlar ışığında radyolojide kullanılan iyotlu, gadolinyum bazlı ve ultrason kontrast maddelerinin güvenliğine ilişkin güncel yaklaşımlar derlenmiştir. Hipersensitivite reaksiyonları, böbrek güvenliği, nefrojenik sistemik fibrozis (NSF), gadolinyum retansiyonu, ekstravazasyon, gebelik ve emzirme, tiroid fonksiyonu, ultrason kontrast ajanları ve ardışık uygulamalar arasındaki güvenli zaman aralıkları ele alınmıştır. 2025 yılında ACR-AAAAI, CAR-CSACI ve ESUR kılavuzları, hafif reaksiyon öyküsünde rutin premedikasyonun önerilmediği ve mümkünse ajan değişikliğinin tercih edilmesi gerektiği sonucuna bağımsız olarak ulaşmıştır. Kontrastla ilişkili ve kontrast kaynaklı akut böbrek hasarının ayrılmasıyla nefrotoksisite riskinin geçmişte abartıldığı anlaşılmış; profilaktik hidrasyon akut böbrek hasarı veya eGFR <30 mL/dk/1,73 m² olan seçilmiş hastalarla sınırlandırılmıştır. Grup II gadolinyum bazlı ajanlarla NSF riski son derece düşük düzeye inmiş, retansiyon konusunda akılcı kullanım ve yarım dozda kullanılabilen gadopiklenol gibi yüksek relaksiviteli ajanlar öne çıkmıştır. Ekstravazasyonda cerrahi konsültasyon kararı hacme değil klinik ciddiyete göre verilmekte, emzirmeye ara verilmesi artık önerilmemektedir. Sonuç olarak kontrast madde güvenliğinde standart protokollerin yerini kanıta dayalı, bireyselleştirilmiş yaklaşımlar almakta ve kurumsal protokollerin düzenli olarak güncellenmesi önem taşımaktadır.
