Ischemic Stroke Post-Transradial Chemoembolization

Abstract

Transarterial chemoembolization is one of the approved locoregional treatment options for hepatocellular carcinoma. The procedure is safe; however, stroke may happen as one of the rarest complications. Our patient is a 68-year-old male who underwent transradial chemoembolization to treat hepatocellular carcinoma, who then developed ischemic stroke on postoperative day 1. The possible causes of stroke in our patient will be presented with review of the literature. Although rare, stroke post-chemoembolization can happen. The presence of intratumoral shunt or inadvertent injection of air bubbles in a coexisting right-to-left shun or the use of transradial approach can increase the risk of stroke.
