Arterial vasospasm after a traffic accident in a 29 year-old man with pelvic fractures and thoracic injury. a Digital subtraction angiography of the left common iliac artery shows arterial vasospasm. Peripheral branches of the internal iliac artery are poorly depicted, and active bleeding cannot be detected. b Digital subtraction angiography obtained after non-selective embolization of the internal iliac artery with gelatin particles shows no active bleeding. Thoracic surgical procedures have been performed to ensure hemostasis after the first embolization session. c The second session of endovascular treatment has been performed because of unstable hemodynamics after thoracic surgery. Digital subtraction angiography of the left internal iliac artery shows scattered active bleeding due to the release of vasospasm
