Recent Management of Surgically Correctable Hypertension

Abstract

Secondary hypertension is elevated blood pressure that results from an underlying, identifiable, often correctable cause. Only about 5 to 10 percent of hypertension cases are thought to result from secondary causes. This study is a metaanalysis of the most common renal, endocrinal and vascular causes of surgically correctable hypertension. Renal artery stenosisis the most common cause of potentially curable secondary hypertension due to activation of renin-angiotensin aldosterone system, with atherosclerosis as the major cause of renal artery stenosis. Fibromuscular dysplasia is a less common cause of renal artery stenosis.early diagnosis in young aged patients, allow surgical management (whether by angioplasty and stenting,or surgical by transplantation or aortorenalbypass) to control blood pressure and to prevent related comorbidities. -Coarctation of the aorta is the narrowing of the medial layer of the vessel. The etiology is most commonly congenital, though it may also be acquired (secondary to Takayasu arteritis or rarely severe atherosclerosis).This disease can affect neonates, infants, and children. -Definitive management involves percutaneous catheter-based repair (angioplasty and/or stent placement) or surgical repair. Performing a stent in selected small children and infants that have sever and symptomatic coarctation of aorta can be effective and safe in improving patients' clinical state, and preventing surgery.
