Presentation transcript:

(A) Simulation of flow diversion of a wide neck aneurysm by the pipeline device (PD). (A) Simulation of flow diversion of a wide neck aneurysm by the pipeline device (PD). A side branch of the chorionic plate artery (CPA) was ligation to form an aneurysm-like sac. A heparinized human blood sample was perfused into the vessel for 30 min. (B) The vessel was opened to inspect the surface of the PD and clot formation. (C) Simulation of intra-arterial thrombolysis with clot sample (black arrow) was loaded into the bifurcation of a CPA. (D) The clot was completely lysed in 23 min by urokinase. (E) Appearance of Onyx embolization at the distal CPA. (F) Digital subtraction angiography appearance of the embolized vessel (white arrow). Degree of adhesiveness of Onyx with the detachable tip of the perfusion catheter was observed. John Ching Kwong Kwok et al.
