Tiroid kistlerine perkütan etanol enjeksiyonu

Öz

Amaç: Benign kistik tiroid nodülü olan ve Doppler ultrasonografi eşliğinde perkütan etanol enjeksiyonu (PEİ) uygulaması ile tedavi edilen 28 hastamızın sonuçları sunuldu. Yöntem: Perkütan etanol enjeksiyonu uygulamasından önce tüm hastalarda ince iğne aspirasyon biyopsisi ile malignite dışlandı. Kist hacmi uzunluk χ yükseklik χ en χ π/6 formülü kullanılarak hesaplandı. Uygulamada başlangıç kist hacminin yarısı kadar %95'lik etil alkol kullanıldı. Hastalarımızın takiplerinde nodül çapı, fibroskleroz oluşumu ve nodül vaskülarizasyonu değerlendirildi. Başlangıç hacmine göre %50'den fazla küçülme başarı olarak kabul edildi. Bulgular: Bir PEİ uygulaması ile hastalarımızın %88.5'inde tedavi edildi. Başarısız olgularda ikinci uygulamayla tedavi oranı %92.9'a yükseldi. Sonuç: Tiroid kistlerinin tedavisinde ultrason eşliğinde PEİ uygulaması yüksek başarı oranlarıyla etkili, ucuz ve güvenilir bir tedavi yöntemidir.

Percutaneous ethanol injection into thyroid cysts

Abstract

Objective: To present the results of 28 patients who were treated by Doppler ultrasound guided percutaneous ethanol injection (PEI) into benign cystic thyroid nodules. Methods: Before percutaneous injection of ethanol, malignancies were excluded with fine needle aspiration biopsy. Volume of the nodule was calculated according to length χ width χ depth χ π/6 formula. During the application, 95% ethanol solution was injected about half of the initial cystic volume. At follow-up nodule diameter, formation of fibrosclerosis and nodule vascularization were evaluated. More than 50% reduction in nodule volume relative to the initial volume was defined success. Results: The success rate with single application of PEI was found 88.5 percent. With administration of the second application of PEI on unsuccessful cases success rate increased to 92.9 percent. Conclusion: Doppler ultrasound-guided PEI injection is a reliable, effective and inexpensive method in the treatment of thyroid cysts with high success rates.
