Depiction of the detachment process of an insulated coil (GDC-10 SynerG, 6 mm × 20 cm) in heparinized human whole blood.

A, During detachment, with the detachment zone dipped in the blood, a dark area of thrombus formation is clearly seen with many gas bubbles generated and floating to the surface level.

B, After detachment, the blood was gently irrigated by saline, and a lobulated thrombus is attached at the proximal tail of the coil part. Many gas bubbles remain in the thrombus.

C, After removal of the fluid, the bubble remains attached in the thrombus; the thrombus is 1.5 mm in diameter.
