Abstract
Amaç: Kronik karaciğer parankim hastalığı olanlarda karaciğer ve dalak sertliğinin klinik önemini araştırmaktır.
Gereç ve Yöntem: Prospektif çalışmamıza, Kasım 2018-Haziran 2021 tarihleri arasında Ankara Üniversitesi Tıp Fakültesi Hastanesi Ultrasonografi
Ünitesi’nde ultrason (US) shear wave elastografi (SWE) ve abdomen US incelemesi yapılan kronik karaciğer parankim hastalığı olan elli hasta dahil
edildi. B-mod incelemede karaciğer boyutu, konturu, ekojenitesi, portosistemik kollaterallerin varlığı ve asit araştırıldı. Portal ven çapı ölçüldü.
Dalak hacmi hesaplandı. Karaciğer ve dalak sertlik değerleri SWE ile ölçüldü. Serum trombosit sayısı not edildi. Tüm hastalar için Child-Pugh skoru
hesaplandı.
Bulgular: Otuz dört hasta Child-Pugh A, 15 hasta Child-Pugh B, 1 hasta Child-Pugh C grubundaydı. Trombosit sayısı 51-360 x109/L arasındaydı. En
yaygın konvansiyonel US bulgusu parankimal heterojeniteydi. Tüm hastalarda splenomegali vardı, ortalama portal ven çapı 12,58 mm idi, 34 hastada
hepatopedal akım vardı. On beş hastada portosistemik kollateraller saptandı. Karaciğer ve dalak sertlik değerleri sırasıyla 4.12 kPa-16.29 kPa ve 9.20kPa-29.19 kPa arasındaydı. Karaciğer ve dalak sertliği arasında pozitif korelasyon vardı (p=0,002). Dalak hacmi ile dalak/karaciğer sertliği arasındaki
ilişki istatistiksel olarak anlamlıydı (sırasıyla p=0,0004, p=0,008). Hem karaciğer hem de dalak sertliği Child-Pugh skoru ile koreleydi (sırasıyla p=0,02,
p=0,00003). Portal ven çapı ile karaciğer/dalak sertliği arasında ve trombosit sayısı ile karaciğer sertliği arasında istatistiksel olarak anlamlı bir ilişki
yoktu (p>0,05). Trombosit sayısı ile dalak sertliği arasındaki korelasyon istatistiksel olarak anlamlıydı (p=0,002).
Sonuç: SWE, hastaların klinik durumu hakkında bilgi sağlayabilir. Dalak sertliğini ölçmek, karaciğer sertliğini ölçmek kadar önemlidir.

Clinical Significance of Liver and Spleen Stiffness: Evaluation with Shear Wave Ultrasound Elastography
Abstract
Objectives: To investigate clinical significance of liver and spleen stiffness in patients with chronic parenchymal liver disease.
Materials and Methods: Fifty patients with chronic parenchymal liver disease who underwent 2D ultrasound (US) shear wave elastography (SWE) in
the Ultrasonography Unit of Ankara University Medical Faculty Hospital between November 2018-June 2021 were enrolled in our prospective study.
Liver size, contour, echogenicity, presence of portosystemic collateralls, and ascites were investigated on B-mode examination. Portal vein diameter
was measured. Splenic volume was calculated. Liver and spleen stiffness values were measured by 2D SWE. Serum platelet count was noted. Child-
Pugh score was calculated for all patients.
Results: Thirty-four patients were grouped as Child-Pugh A, 15 patients were grouped as Child-Pugh B, 1 patient was grouped as Child-Pugh C.
Platelet count was between 51-360x109/L. The most common conventional US finding was parenchymal heterogeneity. All patients had splenomegaly,
the mean portal vein diameter was 12.58 mm, 34 patients had hepatopedal flow. Portosystemic collateralls were detected in 15 patients. Liver and
spleen stiffness values were between 4.12 kPa-16.29 kPa, and 9.20 kPa-29.19 kPa, respectively. There was a positive correlation between liver and
spleen stiffness (p=0.002). The relationship between splenic volume and spleen/liver stiffness was statistically significant (p=0.0004, p=0.008,
respectively). Both liver and spleen stiffness was correlated with Child-Pugh score (p=0.02, p=0.00003, respectively). There was no statistically
significant correlation between portal vein diameter and liver/spleen stiffness, and between platelet count and liver stiffness (p>0.05). The correlation
between platelet count and spleen stiffness was statistically significant (p=0.002).
Conclusion: SWE can provide information about the clinical status of the patients. Measuring spleen stiffness is as important as measuring liver
stiffness.
