Abstract

Sitomegalovirüs enfeksiyonu nadiren portal ven trombozuna yol açabilir. Vakamızda sunduğumuz gibi, son yıllarda bağışıklığı yeterli bireylerde Sitomegalovirüs ilişkili tromboz vakaları dikkat çekmektedir. 31 yaşında erkek hastanın iş başvurusu öncesi rutin taramalarında alanin aminotransferaz ve aspartat aminotransferaz düzeylerinde yükseklik tespit edildi. Aktif yakınması yoktu. Portal venöz doppler incelemesinde sağ portal ven içerisinde lümeni subtotal oklüde eden ekojen trombüs materyalleri tespit edildi. Anti-CMV IgM ve IgG pozitif, trombozu açıklayacak diğer tetkikler normaldi. Anti-CMV IgG düşük avidite, CMV PCR 137 kopya/mL idi ve akut Sitomegalovirüs hepatitine sekonder portal ven trombozu olarak değerlendirildi. Antiviral tedavi uygulanmaksızın, antikoagülan tedavi ile transaminazlar normal düzeye geriledi. Kontrol portal venöz doppler incelemesinde trombüsün çözüldüğü tespit edildi. Portal ven trombozu nedeni araştırılırken hasta asemptomatik olsa da Sitomegalovirüs infeksiyonu akla gelmelidir. Sitomegalovirüs hepatiti varlığında asemptomatik vakalarda portal ven trombozu yönünden inceleme gerekebilir.

CMV hepatitis related portal vein thrombosis “case report”

Abstract

Cytomegalovirus infection is an uncommon etiology of portal vein thrombosis, particularly highlighted by recent cases in immunocompetent individuals. A 31-year-old male who, during routine employment screening, was found to have elevated alanine aminotransferase and aspartate aminotransferase levels, despite being asymptomatic. Doppler ultrasound revealed echogenic thrombus partially occluding the right portal vein. Laboratory tests indicated positive anti-CMV IgM and IgG, with low avidity for anti-CMV IgG, and a CMV PCR level of 137 copies/mL, suggesting portal vein thrombosis due to acute Cytomegalovirus hepatitis. The patient was treated with anticoagulation, resulting in normalization of transaminase levels, while antiviral therapy was unnecessary Follow-up Doppler imaging confirmed thrombus resolution. When investigating portal vein thrombosis, Cytomegalovirus infection should be considered, even in asymptomatic patients. In cases of Cytomegalovirus hepatitis, it is advisable to evaluate for portal vein thrombosis, including in asymptomatic individuals.
