Abstract

Introduction: This study aimed to investigate the relationship between left ventricular ejection fraction (LVEF) measured on preoperative transthoracic echocardiography (TTE) and peak systolic velocity (PSH) and resistance index (DI) calculated on postoperative renal Doppler ultrasonography.

Methods: The study retrospectively included 68 renal transplant patients. TTE measurements were taken for all patients, and LVEF was recorded. Renal Doppler ultrasonography recorded PSH and DI. Patients were divided into two groups based on LVEF below 55% (group 1, n=24) and above (group 2, n=44).

Results: Of the patients participating in our study, 21 (30.8%) were female and 47 (69.2%) were male. The mean age of the patients in the study was 53.2±9.27 years. Urea was significantly lower in patients with LVEF values above 55% (85.9±31.5 vs. 103.3±35.2; p=0.02). On the other hand, PSV and RI were significantly lower in the group with LVEF values above 55% (188.2±33.1 vs. 238.7±40.2; p=0.02; 0.64±0.15 vs. 0.78±0.19; p=0.04, respectively). A negative correlation was also found between LVEF values and PSV and RI (r= -0.731, p=0.007; r= -0.602, p=0.01, respectively).

Conclusion: In this study, renal transplant patients with echocardiographic LVEF greater than 55% had significantly lower RI and PSV determined by renal Doppler ultrasonography.

RENAL TRANSPLANTASYON YAPILAN HASTALARDA KARDİYAK FONKSİYON İLE RENAL KAN AKIMI ARASINDAKİ İLİŞKİ

Abstract

Giriş: Bu çalışma preoperatif transtorasik ekokardiyografide (TTE) ölçülen sol ventrikül ejeksiyon fraksiyonu (SVEF) ile postoperatif renal Doppler ultrasonografide hesaplanan tepe sistolik hız (TSH) ve direnç indeksi (DI) arasındaki ilişkiyi incelemeyi hedeflemiştir.

Yöntemler: Çalışmaya retrospektif olarak 68 renal transplantasyon yapılan hasta dahil edildi. Tüm hastaların TTE ölçümleri alındı SVEF kayıt edildi. Renal Doppler ultrasonografide TSH ve DI’leri not edildi. Hastalar SVEF % 55’in altında (grup 1, n=24) ve üstünde (grup 2, n=44) olmalarına göre iki gruba ayrıldı.

Bulgular: Bizim yaptığımız bu çalışmaya katılan hastaların 21'i (%30,8) kadın 47'si (%69,2) erkekti. Çalışmadaki hastaların ortalama yaşı 53,2±9,27 idi. SVEF değerleri %55'in üzerinde olan hastalarda üre anlamlı derecede düşüktü (85,9±31,5'e karşı 103,3±35,2; p=0,02). Öte yandan, SVEF değerleri %55'in üzerinde olan grupta TSH ve DI anlamlı derecede düşüktü (sırasıyla 188,2±33,1'e karşı 238,7±40,2; p=0,02; 0,64±0,15'e karşı 0,78±0,19, p=0,04). LVEF değerleri ile TSH ve DI arasında negatif korelasyon da bulundu (sırasıyla r= -0,731, p=0,007; r= -0,602, p=0,01).

Sonuç: Bu çalışmada, ekokardiyografik SVEF'si %55'ten büyük olan renal transplantasyon yapılan hastaların renal Doppler ultrasonografi ile belirlenen DI ve TSH anlamlı derecede düşük olarak bulunmuştur.
