Peripheral Arterial Disease
What are Peripheral Arteries ?
Acute problems can be because of a clot forming or a clot getting transferred from somewhere else. A clot in the heart can travel and go anywhere to the brain, arteries, hand or feet and that area can become blocked and ischemic. This calls for an acute emergency. Acute obstruction because of clot and obstruction of a major artery of a limb can cause complete de-vascularization of the limb.
It presents as absolute, severe pain and pale limbs as the blood stops to flow. In contrast with venous obstruction, the artery keeps on pumping the blood but the blood is unable to flow up, so the limb becomes congested and painful which means a high index of suspicion must be raised for an acute arterial obstruction first by confirming the diagnosis and then whether it is an acute thrombus is forming or it is a clot thrown from somewhere else.
