Summary: In Italy, ultrasound guided implantation in liver was performed in 50 patients of 68 gold grain markers 1×4 mm through 17-gauge needles, 78 Gold Anchors 0.4×10 mm through 22-gauge needles, and 17 Gold Anchors 0.28×10 mm through 25-gauge needles. The use of 17-gauge needles resulted in five patients developing abdominal pain and the migration of 4 gold seeds (5.9%). One vagal syndrome occurred when using 22-gauge needle. No complications were reported with the use of the 25-gauge needle. None of the Gold Anchor markers migrated.
