Early and late complications following surgical correction of renovascular hypertension.

In surgery for renovascular hypertension one should try to avoid prothetic material. In general, it seems preferable to use methods without transplanted tissue at all, for instance the direct desobliteration in atherosclerosis or resection and end-to-end anastomosis in fibromuscular disease. General complications should be avoided in a carefully postoperative observation of the patients with exact equilibration of blood vulume and electrolytes.
