Type B aortic dissections accompanied by indications for emergent/urgent correction can frequently be addressed by IR-directed stent place- ment. (Fig. 11-27). End-organ ischemia of cerebral,

A wide variety of life-threatening hemorrhagic events can be effectively addressed by angiography followed by embolization of the culprit vessel (Fig. 11-26). These sources commonly involve the
