The importance of neuropathy in the pathogenesis of foot lesions has been well recognized in diabetes. Blood flow in ischemic limbs has been extensively investigated but the circulation of limbs affected by peripheral neuropathy has received
attention. Some studies on blood flow in peripheral neuropathy have shown a remarkable increase in resting flow, transcutaneous venous oxygen tension, and vascularity, along with loss of the spontaneous variations which occur normally with
activity of the foot in patients with diabetes. The aim of present study is to find out the effects of somatic and autonomic nervous function in early change of blood flow of foot in diabetic patients, We have studied fifty-one patients of
non-insulin-dependent(type II) diabetes with no history of hypertension of diabetic foot ulcers. The evidence of neuropathy was screened by nerve conduction studies and sympathetic skin response of both lower extremities. Blood flow of dorsalis
and posterior tibial arteries was measured by portable doppler machine and presented as pressure index(ankle-to-arm systolic pressure ratio). The patients with sympathetic dysfunction showed significant decrease in pressure index compared to
control and diabetic patients with normal sympathetic function, suggesting that changes of the blood flow occur in diabetic patients with sympathetic dysfunction.
