AN INTERESTING CASE OF SECONDARY HYPERTENSION-A CASE REPORT

Abstract

INTRODUCTION- Renovascular hypertension
is an important cause of secondaryhypertension.
Renal artery stenosis
is commonly caused by atherosclerosis
(in 90 percentage ofcases) and fibromuscular
dysplasia (in 10 percentage of
cases).CASE PRESENTATION- A
youngfemale aged 20 years was admitted
with giddiness and hypertension.
Clinically she had right renalartery bruit .
On evaluation found to have unilateral
contracted right kidney in ultrasound.
Dopplerstudy showed dampened flow
and increased acceleration time in right
renal artery. Subsequent CTangiogram
revealed right renal artery stenosis in the
proximal segment.Diuretic renal study
showedreduced size, perfusion and function
of right kidney. Hypertension was
easily controlled withantihypertensive
drugs and she was referred to higher
centre for surgical correction.
CONCLUSION -Fibromuscular dysplasia
is the most common cause of
renovascular stenosis in patients less
than 40years especially in females, typically
presenting as hypertension. Incontrast
to atherosclerotic renal
artery stenosis , fibromuscular dysplasia is
often cured by angioplasty.
