Thrombocytopenia can be found in patients with liver cirrhosis related to hepatitis C virus. Both hypersplenism and increased platelet autoantibodies have been hypothesized as mechanisms responsible for thrombocytopenia. A 55-year-old man with hepatic cirrhosis secondary to hepatitis C and documented portal hypertension was admitted with hypersplenism, severe thrombocytopenia (900/μL) and gingival bleeding, which were refractory to corticosteroid therapy. Partial splenic embolization was performed radiologically by injection of polyvinyl alcohol particles. Splenic volume decreased 45% following the embolization. Over 10 days following the procedure, the platelet count increased progressively from 4,450 to 89,700/μL. Postembolization syndrome was the main side effect, but no life-threatening complications were detected. In conclusion, partial splenic embolization can be a safe and effective therapy for hypersplenism in cirrhosis.

Thrombositopeni hepatit C virüsüne sekonder karaciğer sirozlu hastalarda karşılaşılabilen bir durumdur. Bu hastalardaki trombositopeniden sorumlu mekanizmalar olarak hipersplenizm ve dolaşımda artmış platelet otoantikorları gösterilmektedir. Hepatit C virüsüne sekonder siroz ve dökümante edilmiş portal hipertansiyon ve hipersplenizmi olduğu bilinen 55 yaşında erkek hasta şiddetli trombositopeni (900/microL) ve diş eti kanaması nedeniyle başvurdu. Kortikosteroid tedavisine cevap vermeyen hastaya radyolojik olarak polyvinyl alkol partikülleri ile parsiyel splenik embolizasyon yapıldı. Embolizasyonu takiben dalak volumu %45 azaltıldı. İşlemi takip eden 10 gün içinde platelet sayısı progressif olarak 4,450 den 89,700/ microL'ye kadar yükseldi. Postembolizasyon sendromu olarak hayati tehlike yaratmayan bazı yan etkiler görüldü. Sonuç olarak parsiyel splenik embolizasyon sirotik hastalardaki hipersplenizm tedavisinde güvenli ve etkili bir tedavi yöntemidir.
