Nine hypertensive patients were operated by revascularization procedure, in our institute, form January 1963 to August 1984. The revascularization procedure were aorto-renal artery bypass in 2 cases, resection with end to end renal artery anastomosis in one case, resection with end to end left colic-renal artery reanastomosis in one case, resection with end to side aorto-renal artery reanastomosis in one case, renal angioplasty with patch graft in one case, percutaneous transluminal angioplasty (PTA) of renal artery in one case, renal autotransplantation with renal angioplasty in 2 cases.
Although early one case was lost by acut renal failure, the other cases of renovascular hypertension (RVHT) were healthy free from hypertension after follow-up from 2 months to 16 years.
The Choice of operative methods for RVHT should be based on the type and severity lesions present, and should be based on the general condition. In addition to the choice of operative methods, preparations of protection to ischemic damages of Kidney during operation should be done. From 1981, hypertensive patients due to renal artery stenosis were administered of vitamin E (Vit. E) and coenzyme Q10 (CoQ10) as protective agents for ischemic damages of kidney. We performed operation for RVHT with good results without severe renal failure in pretreatment group.
