Key Symptoms Of Peripheral Vascular Disease

Thick Toenails

Onychogryphosis is a term used to describe a condition of the nails that causes the nail to grow faster on one side than the other. The result of this abnormal nail growth is unnaturally thick nails that curve irregularly. Onychogryphosis is a common manifestation of peripheral vascular disease because of the restriction in the ability of oxygenated blood to reach the capillaries that feed the nail bed of the toes. Plaques in the arteries cause them to become narrow and allow a lower quantity of blood through them at any given time. The nail matrix needs a constant and even supply of oxygen and nutrients to grow the nail properly. However, the nail will grow more on one side than the other if only one part of the nail matrix is receiving enough blood. This manifestation is usually the most prevalent in an affected individual's big toes but may present in the smaller toes as well.
