Renovascular hypertension

Show Summary Details

Preview

Impaired renal flow due to obstruction of the renal arteries causes hypertension by activation of the reninangiotensinaldosterone system. The incidence of this disease is increasing due to the ageing population. Investigations to rule out renal artery stenosis should only be done in select patients where there is a clinical suspicion. Renal angiogram is the gold standard test for diagnosis. Medical therapy should be instigated in the first instance. Percutaneous angioplasty and surgical revascularization provide similar outcome results.
