Update on Transarterial Chemoembolization with Drug-Eluting Microspheres for Hepatocellular Carcinoma.

Conventional transcatheter arterial chemoembolization (c-TACE) is a widely used first-line palliative treatment for patients with unresectable hepatocellular carcinoma (HCC). Despite the effectiveness of c-TACE, to date, technique and procedure scheduling has not yet been standardized. Drug-eluting microspheres (DEMs) were therefore introduced to ensure more sustained and tumor-selective drug delivery for permanent embolization.

Portal Vein Thrombosis after Endovascular Embolization of Splenic Artery for a Symptomatic Arterioportal Fistula: A Case Report and Literature Review.

Arterioportal fistula (APF) can induce severe portal hypertension and therefore requires appropriate and timely management. Endovascular treatment is increasingly used for the treatment of APFs due to its minimally invasive nature, although this procedure can lead to potentially fatal portal vein thrombosis (PVT). Reports of this complication are, however, rare.
