P-39 EXPERIENCE IN THE MANAGEMENT OF REFRACTORY HEPATIC ENCEPHALOPATHY THROUGH ENDOVASCULAR THERAPY

Introduction: Hepatic encephalopathy (HE) is the most common neuropsychiatric syndrome secondary to portal hypertension. It usually responds to medical treatment, but sometimes HE is refractory (RHE) to usual treatment. In some patients it may be important to consider management alternatives. Endovascular therapy (ET) could be a therapeutic option in selected cases that is performed with very low frequency and the evidence is scarce. Objectives: To present our experience in the management of RHE with ET. Methods: The pre and post-procedure clinical characteristics of 10 patients with RHE undergoing splenic vein embolization (n: 5) or porto-systemic bypass embolization (n: 5) between 2009-2019 were retrospectively analyzed. Results: 7/10 were men, average age 67 years (62-79), in 70% the cause of cirrhosis was NASH, the Child Pugh average score was B (8 points), (6-11) and MELD-Na was 13 points, (9-20), in 5 patients the ammonia prior to the procedure was 134 mmol / l (range: 90-180, VN <30), the average degree of HE was 2-3 on the scale of West Haven. One week after the procedure, in all patients the grade of EH decreased to 0-1 and the ammonium to 88 mmol / l. At one month, the grade of HE was 0 in all patients and that of ammonia was 83 mmol / l. There were no complications from the procedure. Conclusion: The results obtained confirm that ET in patients with Child B HE and MELD-Na maximum of 20 is a safe and effective procedure, associated with clinical improvement in RHE.
