During the last few years, renal hypertension has become a subject of increasing importance. The development of improved radiological techniques, notably intravenous and intra-arterial digital subtraction angiography, has made the diagnosis of renal artery stenosis more reliable, while advances in vascular surgery and the introduction of percutaneous trans luminal angioplasty have caused major changes in clinical practice. The increasing use of such potent antihypertensive agents as the angiotensin I converting enzyme inhibitors has empha­ sized the problem of renal artery stenosis in older patients with wide­ spread vascular disease as well as improving the prognosis of patients with accelerated hypertension. This book examines the surgical and medical aspects of renal hyper­ tension in the light of these recent advances. Each chapter has been written by a recognized expert in the field and provides information of relevance and practical importance to the average clinician. The developments of the last decade have emphasized that renal hyper­ tension is no longer a matter only for the nephrologist but a subject on which all clinicians should be well informed.
