title: An experimental model to retraining in microvascular suture.
abstract: OBJECTIVE
  To demonstrate an experimental model of up to four hours a week of independent study that allows relearning in microvascular sutures.
  
  
  METHODS
  Wistar rats between 200 and 500 grams surplus research experiments were used. Femoral vessels are covered on one or both sides through a groin incision obliquely along the inguinal ligament. Femoral artery and vein are isolated and measured being clamped and cut. The individual performs in microvascular anastomosis complexity arterial and venous terminoterminal sequence. terminolateral and venous and arterial grafts in vessels. Permeability is evaluated by testing vascular patency after creation of microvascular anastomosis.
  
  
  RESULTS
  In the first specimen, only arterial and venous vascular anastomosis are performed terminoterminal. The average diameter of the femoral veins varies from 0.8 to 2 mm between rodents (artery, between 0.6 and 1.4 mm, between 0.8 and 2 mm vein). The superficiality of the vessels allows faster dissection, may also be held in other inguinal region.
  
  
  CONCLUSIONS
  The model of individual retraining allows learning microvascular suture in individuals of permanent staff.
