[Surgery for the repair of renal arteriovenous fistula and its hemodynamic impact].

The case of a 42-year-old woman with an arteriovenous fistula on the left kidney is described. Twenty-six years before presentation, a percutaneous renal biopsy had been obtained. The patient presented with arterial hypertension, angina and dyspnea. We studied the hemodynamic parameters before and after surgical repair of the fistula. Pulmonary artery pressure was very high but fell to normal after surgery, indicating that the fistula was responsible for hemodynamic complications that increased the level of surgical risk.
