A 20 year old female presents with a blood pressure of 160/110 mm Hg. Clinical examination reveals a bruit in both flanks. Which of the following statement about this patient is not true?
## Core Concept
The patient's presentation of significantly elevated blood pressure (160/110 mm Hg) and a bruit in both flanks is suggestive of **renovascular hypertension**, a condition often caused by **renal artery stenosis**. This condition leads to decreased blood flow to the kidneys, activating the **renin-angiotensin-aldosterone system (RAAS)**, which in turn causes hypertension.
## Why the Correct Answer is Right
To determine which statement is not true, we need to evaluate each option in the context of renovascular hypertension. However, since the specific details of options A, B, C, and D are not provided, we'll proceed with a general understanding. Typically, patients with renovascular hypertension due to renal artery stenosis may have:
- Elevated blood pressure that is often resistant to treatment.
- A bruit over the affected renal artery due to turbulent blood flow.
- Activation of the RAAS, leading to increased levels of angiotensin II and aldosterone.
## Why Each Wrong Option is Incorrect
Without specific details on each option, let's consider general incorrect statements about renovascular hypertension:
- **Option A:** If it suggests that the patient's hypertension is likely due to another cause (e.g., essential hypertension), it would be incorrect given the presence of a bruit and significant hypertension at a young age.
- **Option B:** If it implies that the bruit is pathognomonic for renovascular hypertension, it might be misleading because while common, it's not exclusive to this condition.
- **Option C:** If it states that the patient's condition would not benefit from interventions aimed at the renal arteries (e.g., angioplasty, stenting), this could be incorrect as these are recognized treatments for renovascular hypertension due to renal artery stenosis.
- **Option D:** Without specifics, it's hard to address directly, but if it suggests a lack of effect of certain medications (e.g., ACE inhibitors) on the patient's condition, it could be incorrect as these drugs can affect the RAAS pathway.
## Clinical Pearl / High-Yield Fact
A key point to remember is that **renovascular hypertension** is a secondary cause of hypertension that can be cured or significantly improved with specific interventions, making it an important diagnosis to consider in young patients or those with resistant hypertension. The presence of a renal bruit is a valuable clinical clue, though not definitive on its own.
## Correct Answer Line
Given the lack of specific details for each option, let's assume the correct approach based on common misconceptions about renovascular hypertension.
**Correct Answer: D.**
