INFUSION OF LIPIODOL INTO THE POSTERIOR INTERCOSTAL ARTERY CAUSING SPINAL INFARCTION-A CASE REPORT-

A 60-year-old man who had had transarterial embolization six times for multiple hepatocellular carcinoma received seventh transarterial embolization at the hospital. Procedures included that 4mg of smankus was dissolved in 10ml of lipiodol, and 5. 3, and 1ml of the solustion were infused into the right inferior dia-phragmatic artery and right posterior intracostal artery (between the 9th and 10th) which fed the tumor. The patient complained of numbness and pain of the bilateral lower extremities immediately after the infusion. On the next day the patient manifested symptoms of transverse lesion of spinal cord which did not recover hereafter. Magnetic resonance imaging revealed an infarction image at the level of Th 9/10. Reevaluation of an angiography which was taken before surgery showed spinal artery branched from the 9th posterior intercostal artery. Thus, it was thought that lipiodol flew into the spinal artery through intracostal artery causing spinal infarction.
