Arterial Injury in Dogs after Multiple Percutaneous Catheterizations at the Same Site of Entry

Published Online:https://doi.org/10.1148/108.2.295

Seventeen dogs which had undergone selective visceral arteriography 3 to 10 times over a period of three years were catheterized repeatedly via the femoral arteries. Seven dogs showed arteriographically demonstrable abnormalities of the arterial wall, corresponding to the histological findings of intimal hyperplasia with collagen deposition and fibroblastic proliferation in the media. The presence of these lesions did not correlate with the number of catheterizations. None of the dogs demonstrated signs of peripheral arterial insufficiency. These findings may be of greater significance when applied to human patients, due to their higher incidence of arteriosclerotic disease and their less pronounced collateral circulation.
