title: [Renal angioplasty with stent using CO2 as contrast medium: report of one case].
abstract: Revascularization procedures for atherosclerotic renovascular hypertension are aimed to improve or cure hypertension and to reduce the progression to ischemic nephropathy and renal failure. Renal angioplasty is the preferred method, but a common complication is contrast-induced nephropathy. To avoid or lessen this complication, CO2 can be used as a contrast medium. We report a 68 year-old woman with renovascular hypertension and mild deterioration of renal function in whom we implanted an stent using digital substraction angiography and CO2 as contrast medium, which was injected manually. We obtained satisfactory images and we ended the procedure without complications. Blood pressure fell and creatinine levels did not change.
