Renovascular hypertension and Takayasu's disease
Insights
Surgical correction of renal hypertension in Takayasu's disease offers a viable treatment option. This extensive procedure demonstrated low morbidity and mortality, with significant success in curing or improving hypertension.
Area of Science:
- Cardiovascular Surgery
- Nephrology
- Vascular Disease
Background:
- Takayasu's arteritis can cause renovascular hypertension, a severe condition.
- Medical management is often insufficient for hypertension secondary to Takayasu's disease.
- Surgical intervention is considered when medical therapy fails.
Purpose of the Study:
- To evaluate the efficacy and safety of surgical correction for renal hypertension in Takayasu's disease.
- To compare surgical outcomes with those of other renovascular hypertension etiologies.
Main Methods:
- Retrospective analysis of 18 patients with Takayasu's disease undergoing surgical correction.
- Assessment of perioperative morbidity and mortality.
- Long-term follow-up to determine hypertension cure and improvement rates.
Main Results:
- Low perioperative mortality (1 death in 18 patients).
- High success rate: 67% cured, 28% improved hypertension.
- Outcomes comparable to surgical treatment for fibromuscular dysplasia or atherosclerosis-related renovascular hypertension.
Conclusions:
- Surgical correction is a safe and effective treatment for renal hypertension secondary to Takayasu's disease.
- The procedure yields favorable long-term results, comparable to other causes of renovascular hypertension.
- Surgery should be considered for patients with Takayasu's disease and refractory hypertension.
Abstract:
A total of 18 patients underwent surgical correction of renal hypertension secondary to Takayasu's disease after unsuccessful maximum medical therapy. Although the patients required an extensive surgical procedure, the morbidity and mortality rates were low (1 perioperative death in 18 patients). Followup showed that 67 per cent of the patients were cured of the hypertension and 28 per cent were improved. The results appear as good as those seen in the treatment of renovascular hypertension owing to fibromuscular disease or atherosclerosis.
