State of the art review: The management of chronic vascular disorders in the hand and upper limb.

This review article summarizes the basic principles of vascular anatomy, physiology, diagnostic work-up and treatment for patients with nontraumatic upper extremity vascular disorders. Vascular disorders can be considered vasospastic or occlusive. The most commonly encountered vasospastic condition is Raynaud's Phenomenon secondary to scleroderma. While historically this has been managed medically with vasodilators, more advanced cases can benefit from surgical treatment to improve blood flow and minimize tissue loss, with compelling evidence that earlier surgical intervention can modify disease process and should be considered. Occlusive disease can present as aneurysm or thrombosis and often requires surgical treatment with resection of the occluded segment with or without vascular reconstruction. In advanced atherosclerotic disease or end stage ischemia, arterialization of the venous system can be considered to avoid more proximal amputations.
