Non-traumatic vascular emergencies: imaging and intervention in acute arterial conditions.

Methods of imaging and intervention in acute non-traumatic vascular arterial conditions has changed substantially during recent years. Computed tomography, MRI angiography and, more recently, intravascular ultrasonography (IVUS) have replaced to a large extent conventional diagnostic angiography. An increasing number of patients are treated by endovascular interventions and numerous new treatment methods have been evaluated. Technical development of new equipment and instruments, increasing skill of interventional radiologists and better understanding of events following interventions improve continuously results of the treatment. Radiologic diagnosis and intervention have important roles in the treatment of acute non-traumatic vascular arterial conditions.
