Abstract

Renal PTA or stenting is the method of choice for the treatment of renovascular hypertension. 48 vessels of 35 patients were treated at our institution. All patients were followed up regularly by means of routine sonographic examinations. In 15 patients, contrast-enhanced sonography and CT angiography were also performed. 2 occlusions and 10 cases of a suspicion of restenosis were diagnosed sonographically. Contrast-enhanced sonography facilitated visualization the main renal artery, even in heavy patients, and made the confidence level higher. The 2 occlusive cases were treated successfully with transcatheter local thrombolysis. 8 of the 10 stenosis cases were proved by CT angiography. No false-negative cases occurred this our series. Sonography is the imaging modality of choice for the follow-up of patients after renal artery reconstruction. Contrast-enhanced sonography is a useful complementary method in heavy patients. CT angiography is indicated in doubtful cases or when precise display of the site of the stent is necessary.
