Introduction: The aim of this study is to compare various modifications of Bentall procedure for early complications and long-term follow-up results.

Patients and Methods: One hundred forty-nine patients underwent proximal aortic root replacement with composite valve-conduit graft between 1995 and 2014. Bentall procedure and its modifications (Cabrol procedure and hemi-inclusion) were evaluated for short- and long-term outcomes. Patients with concomitant procedures, arch repair, or valve-sparing procedures were excluded from the study.

Results: In this study, 64 patients have met the inclusion criteria: 20 patients were included in the button Bentall group, 32 patients in the hemi-inclusion Bentall group, and 12 patients in the Cabrol group. Preoperative patient demographics were similar in all groups. The hemi-inclusion technique had better early outcomes, including less intraoperative blood transfusion, short cardiopulmonary bypass, and better in-hospital mortality rates (p< 0.05). However, the long-term all-cause mortality rates did not differ between the groups (p> 0.05).

Conclusion: The hemi-inclusion Bentall technique might be used as a safe alternative approach for various aortic root diseases due to better hemostatic properties and lesser in-hospital mortality rates.

Modifiye Bentall Prosedürlerinin Uzun Dönem Sonuçları

Giriş: Bu retrospektif çalışmanın amacı, aort kökü hastalığı olan hastalarda Bentall prosedürleri çeşitli modifikasyonlarının kısa ve uzun dönem sonuçlarını araştırmaktır.

Hastalar ve Yöntem: 1995-2014 yılları arasında 149 hastaya kompozit kapak-tup grefti ile proksimal aort kökü replasmanı yapıldı. Bentall prosedürü ve modifikasyonları (Cabrol prosedürü ve Hemi-inklüzyon) kısa ve uzun dönem sonuçları açısından değerlendirildi. Eşlik eden prosedürler, ark tamiri veya kapak koruyucu prosedürleri olan hastalar çalışma dışı bırakıldı.

Bulgular: Hastaların 64’ü dahil edilme kriterlerini karşılamıştır (Buton Bentall grubunda 20 hasta, Hemi-inklüzyon Bentall grubunda 32 hasta, Cabrol grubunda 12 hasta). Preoperatif demografik veriler tüm gruplarda benzer bulunmuştur. Hemi-inklüzyon tekniği, daha az intraoperatif kan kaybı ve transfüzyon gereksinimi, kısa kardiyopulmoner bypass ve daha iyi hastane içi mortalite gibi kısa dönem sonuçlarla sonuçlanmıştır (p< 0.05). Uzun dönemli tüm nedenlere bağlı mortalite oranları açısından gruplar arasında fark bulunmamıştır (p> 0.05).

Sonuç: Hemi-inklüzyon Bentall tekniği, daha iyi hemostatik özellikler ve daha az hastane içi mortalite oranları nedeniyle çeşitli aort kökü hastalıkları için güvenli bir alternatif yaklaşım olarak kullanılabilir.
