The first important question is whether or not the injured vessel can be sacrificed. The answer to this partially depends on whether you would expect the tissue distal to the target artery to remain viable or become ischemic after embolization. If sufficient collaterals are available, the tissue supplied by the target vessel may not be affected. So for example, embolizing a gastric branch to stop post-gastros-tomy bleeding (Fig. 7.3) is unlikely to cause any ischemia due to the rich collateral supply around the stomach. Tissue distal to the injured vessel may also be safe from ischemia if there is an alternate blood supply. For example, portal venous flow into the liver allows safe embolization of even major trunks of the hepatic artery.
