[Two cold legs]

Bilateral acute lower limb ischaemia is rare. Usually the diagnosis is based on clinical findings. In four patients, three women aged 51, 48, and 72 and a man aged 64 years, bilateral acute ischaemia of the lower limbs was diagnosed, due to different causes: arterial cardiac myxoma embolism, arterial thrombosis probably due to paraneoplastic coagulopathy, aortic dissection, and arterial thrombosis due to cardiac insufficiency, respectively. The management of these conditions includes restoring the circulation as soon as possible. Reperfusion can be achieved by thromboembolectomy or thrombolysis. In patients with underlying atherosclerosis angiography is useful, but time loss must be avoided. The outcome in patients with bilateral ischaemia of the lower limbs depends on the preoperative ischaemia time and the cardiac situation. The mortality varies between 20 and 50%.
