We used only ethanolamine oleate (EO) in five; EO and coils in five; EO, coils and n‐butyl 2‐cyanoacrylate (NBCA) in two; and coils and NBCA in two patients as embolic materials. The rate of primary and secondary technical success was 93% (13/14 patients) and 100%, respectively. No major complications were encountered related to PTE. Follow‐up period was a median of 27 months (range, 12–79). All patients had sustained disappearance of PSE. PSE recurred in one patient because of another PSS development. Thus, clinical success was achieved in 93% (13/14 patients). The ammonia levels 1 year after PTE were significantly improved compared with pre‐PTE (median, 102 vs 41 μmol/L) and maintained lower levels 2 and 3 years later. Child–Pugh scores did not change significantly. Esophageal varices were aggravated in 29% (4/14 patients). Five patients died, but no death of hepatic failure related to PTE was encountered.</p> </sec> <sec id="hepr12181-sec-0004" sec-type="section"> <title>Conclusion</title> <p>PTE could be one of the useful treatment options for PSE.</p> </sec> </abstract>
