BCVI grading scale. (a) Illustration depicts a grade I injury, characterized by minimal intimal injury with vessel wall irregularity, dissection, or intramural hematoma, with less than 25% luminal stenosis. (b–d) Illustrations depict grade II injuries with intraluminal thrombus (b), dissection with a raised/displaced intimal flap (c), and intramural hematoma (d), with greater than 25% stenosis. (e) Illustration depicts a grade III injury pseudoaneurysm, seen as a focal outpouching/dilatation through a disrupted vessel wall. (f) Illustration depicts a grade IV injury, with dissection or thrombus causing vessel occlusion. (g) Illustration depicts a grade V injury, with complete vessel transection and extravasation.
