OLIVEIRA, Raimundo Rosendo de et al. Alternative therapy for microvarices and telangiectasias with use of needle. J. vasc. bras. [online]. 2007, vol.6, n.1, pp.17-24. ISSN 1677-5449.

BACKGROUND: The development of an alternative to the conventional therapy for microvarices and telangiectasias without using chemical products aims at reducing side effects, using a needle for mechanical lysis of vessels. It uses Lohmann Brown hens as the experimental model. OBJECTIVE: To develop a new technique, creating an alternative treatment without using chemical products, aiming at the reduction of side effects. METHODS: Thirty Lohmann Brown hens were used, 15 submitted to the conventional method of treating microvarices and telangiectasias (control group) and 15 receiving the proposed experimental treatment (experimental group). The experimental group was treated using a needle for vascular lysis, passing through the whole extension of chosen vessels in staggered punctures until the whole vessel was reached. The control group was treated with ethanolamine oleate and 50% glucose, puncturing the vessel with a 13 x 3 mm needle and injecting on average 0.3 mL of the solution in each vessel. RESULTS: Of the 50 vessels treated in the experimental group, two presented total recurrence, five partial recurrence and 43 satisfactory destruction (lysis), whereas of the 51 vessels treated in the control group, four presented total recurrence, 12 partial recurrence, 22 satisfactory destruction and 13 presented conduit vessel stiffness. CONCLUSION: The present study demonstrated that the experimental method using a needle for vascular lysis is more efficient for the treatment of microvarices when compared with the conventional method, due to reduction in recurrence rates and absence of hyperchromatism of conduit vessel stiffness.
