Objective: To experimentally evaluate the effectiveness of stenting from the external carotid artery to the common carotid artery as a measure to prevent blood clots from flowing to the internal carotid artery.
Methods: The Casper stent was placed from the external carotid artery to the common carotid artery in a silicone vascular model. Experimental models of blood clots were made using commercially available slime. The inner lumen of the silicone tube was filled with normal saline. Blood clots were infused to the distal side at a pressure of 150 mmHg. As a contrasting experiment, only normal saline was injected into the silicone tube at a pressure of 73.5 mmHg both before and after stent displacement. The volume of saline that flowed into the external carotid artery and the internal carotid artery was measured.
Results: Blood clots rarely stayed at the bifurcation lesion, and none flowed to the internal carotid artery. Stent placement from the external carotid artery to the common carotid artery did not hinder the flow through the internal carotid artery.
Conclusion: Stenting from the external carotid artery to the common carotid artery prevented blood clots from flowing to the internal carotid artery without disturbing normal blood flow through the internal carotid artery.
