  • a Distal embolization, vessel damage, vasospasm, and thrombus were evaluated at time 0 and at the chronic period. The rating is for both time periods, unless stated otherwise.

  • b There were no angiographic observations of vessel damage, but the entire kidney was diminished in size.

  • c Severity grade of lesions at histology: 1 = minimal, 2 = mild, 3 = moderate, 4 = marked.
