Endovascular Treatment of Renovascular Hypertension | ||
|
Although most cases of hypertension comes as essential hypertension, approximately 5% of hypertension is due to narrowing of one or both renal arteries. Although traditional treatment consisted of a surgical bypass from the aorta to the affected renal artery, today, endovascular treatment using percutaneous balloon angioplasty and stent placement provides a very effective therapy for these lesions. |

In carefully selected patients, this treatment results in almost immediate improvement in their blood pressures and reductions in their antihypertensive drug requirements. In the smaller subset of people with renal insufficiency, it may also result in modest improvements in their serum creatinine. The procedure involves a single groin puncture under local anesthetic and an overnight stay in the hospital. |
