This course corresponds to chapter Peripheral arterial disease in the European Curriculum and Syllabus for Interventional Radiology. 



In acute limb ischaemia (ALI), the occlusion involves the lower extremity arteries. ALI is characterised by an acute decrease in peripheral perfusion, which may threaten viability and may result in tissue loss with potential amputation if treatment is unsuccessful. The main causes are arterial emboli or thromboembolic events from atherosclerotic disease. Careful assessment of the patient is necessary to induce immediate therapy, including percutaneous revascularisation methods, medical therapy, surgery or a combination of these. Incidence of ALI is about 1.5 patients per 10,000 population a year. The classical clinical symptoms are the six “Ps”: paraesthesia, pain, pallor, pulselessness, poikilothermia and paralysis. ALI is categorised depending on sensory and motor deficit, whereas category IIa and IIb represent threatened limb, which may be salvageable if promptly treated. While medical therapy is the first-line treatment, endovascular and surgical treatment are both options, while endovascular techniques offer fast and immediate minimally invasive treatment options with low morbidity and mortality.


Learning objectives

  • Learn to describe the underlying cause and pathophysiology of acute arterial occlusion
  • Describe and categorise acute critical limb ischaemia
  • Learn about different treatment options and how to apply them in different categories
  • Learn about different interventional treatment devices and how they work
  • Learn about potential complications
  • Learn about outcome results
