Acute Peripheral Arterial Occlusion
Key Points
Acute peripheral arterial occlusion is characterized by severe pain, cold sensation, paresthesias (or anesthesia), pallor, and pulselessness in the affected extremity. Treatment consists of embolectomy, thrombolysis, or bypass surgery. Despite treatment, about 11% of patients with acute arterial occlusion require limb amputation.
