| Popis: | We investigated 663 patients with renovascular hypertension (349 males and 314 females), who were surgically treated at 73 institutions of Urology or Surgery in Japan from 1963 to 1988. There were 294 cases with fibromuscular dysplasia (FMD), 178 with atherosclerosis (SC), 104 with aortitis syndrome (AO) and 87 with other causes. The mean age was 27 years old for FMD, 52 years for SC and 29 years for AO. Thirteen % of FMD, 19% of SC and 38% of AO had stenoses in both renal arteries. Since percutaneous transluminal angioplasty (PTA) has begun in early 1980's, the number of operative cases has been decreased, especially in the case of FMD due to a good result by PTA. Nephrectomy was done in 38% of 704 operations. Aortorenal bypass and autotransplantation were performed in 49% and 26% of the rest, respectively. Recently, autotransplantation has increasingly been applied for complicated vascular lesions. As regards prognosis of the surgical treatment, 77% of FMD, 59% of SC and 50% of AO presented normal blood pressure with or without antihypertensive drugs at least for 10 years after an operation. However, among the patients with normal blood pressure who were observed for more than 5 years, 30% of FMD, 56% of SC and 44% of AO had taken antihypertensive drugs. Eleven patients (1.7% of all) died within one month after the operation, 5 patient of whom had bilateral stenoses. In conclusion, PTA is the first choice for renovascular hypertension and surgery has been done for more difficult and complicated cases in which PTA is ineffective.(ABSTRACT TRUNCATED AT 250 WORDS) |
