A Rat Model of Thrombosis in Common Carotid Artery Induced by Implantable Wireless Light-Emitting Diode Device

Figure 4

Ultrasound images of common carotid artery (CCA) after single LED irradiation with 6, 5, and 4 mW/cm2 for 4 h. The CCA is occluded immediately after 6 mW/cm2 LED irradiation. However, CCA is severely stenotic immediately after 4 and 5 mW/cm2 irradiation but is found to be recanalized at 7 days after irradiation. Pre-OP: before LED irradiation; post-OP: immediately after LED irradiation; post-OP 3 d: 3 days after LED irradiation; post-OP 7 d: 7 days after LED irradiation. The non-LED-irradiated right CCA is used as a control. White small arrowheads indicate the CCA bifurcation. White arrows demonstrate the formation of thrombus in the CCA.
