Glucose as a cause of and treatment for cutaneous necrosis.

Sclerotherapy remains one of the procedures most frequently performed by Brazilian vascular surgeons. Knowledge of its complications is indispensable to enable us to avoid them. The severe side effects of this method of treatment for telangiectasias of the lower limbs are rare and are often associated with technical errors or the dose injected. Complications are predominantly local, but are sometimes difficult to resolve. We report a case of formation of cutaneous necrosis after chemical sclerotherapy using hypertonic glucose (75%), which healed when treated with a topical preparation containing vaseline and 60% glucose, with satisfactory esthetic results.
