Chronic Liver Disease, Thrombopenia
Conditions
Brief summary
In this study, patients with chronic liver disease undergoing selective invasive and minimally invasive surgery combined with thrombocytopenia were enrolled. After enrollment, liver disease treatment was supplemented with avatripopal for 5 days. Biochemical indexes of avatripopal were monitored during treatment and after withdrawal. The proportion of patients with platelet count ≥50×10\^9/L on the day of selective invasive and minimally invasive surgery was analyzed. The incidence of adverse events was observed.
Detailed description
This is a single-center, single-arm, prospective study. Patients with chronic liver disease undergoing selective invasive and minimally invasive surgery combined with thrombocytopenia. After enrollment, liver disease treatment was supplemented with avatripopal for 5 days. The baseline demographic data and biochemical data of the subjects were collected. Biochemical indexes of avatripopal were monitored during treatment and after withdrawal. The proportion of patients with platelet count ≥50×10\^9/L on the day of selective invasive and minimally invasive surgery was analyzed. The incidence of adverse events was observed. To investigate the efficacy and safety of avatripopal in chronic liver disease patients with thrombocytopenia undergoing elective invasive and minimally invasive surgery. To provide reference for related clinical treatment.
