[Anatomic reconstruction of native coronary arteries and vein graft with less shortening wallstent]. / Reconstrução anatômica das artérias coronárias nativas e das pontes de safena utilizando less shortening wallstent.

PURPOSE: To evaluate the advantage of the wallstent in the treatment of long or multiple lesions. METHODS: Thirty eight patients with mean age 66 years underwent wallstent implantation. Fourteen had lesions in the left anterior descending, 12 in the right coronary, nine in the circumflex and four in a vein graft. The technique for implantation requires an accurate quantification of the vessel diameter, because the chosen stent should be 1.5 mm larger than the target vessel. A new technique using additional inflations with high pressure balloons was applied. RESULTS: Successful implantation occurred in 95%. We did not have success in two patients. One of them due to damage in the stent and the other to unsuccessful liberation. Both patients were submitted to conventional angioplasty without complications. CONCLUSION: The wallstent implantation can be successfully performed with high success rate, but late angiographic results still demand further studies.
