Medial arterial calcification is frequently seen in diabetic patients with severe diabetic
neuropathy. Sixty patients (19 diabetic and 41 non-diabetic) were examined
radiologically for typical Monckeberg's sclerosis of feet arteries 6-8 years after uni- or
bilateral lumbar sympathectomy. Fifty-five out of 60 patients (92%) revealed medial
calcification. This calcification was observed in both feet of 93% of patients, who had
undergone bilateral operation. After unilateral sympathectomy the incidence of calcified
arteries on the side of operation was significantly higher than that on the contralateral
side (88% versus 18%, p less than 0.01). Although diabetic patients showed longer
stretches of calcification than non-diabetic subjects, the difference was not significant in
terms of incidence and length. Of 20 patients who had no evidence of calcinosis
pre-operatively, 11 developed medial calcification after unilateral operation exclusively
on the side of sympathectomy. In seven patients calcinosis was detected in both feet after
bilateral operation. In conclusion, sympathetic denervation is one of the causes of
Monckeberg's sclerosis regardless of diabetes mellitus.
