Renаl Artery Stenоsis / Renоvаsculаr Hypertensiоn (Study Outline) 1. Background Definition: Narrowing of one or both renal arteries causing reduced renal perfusion, activating RAAS → secondary hypertension. Etiologies (high-yield): Atherosclerotic RAS (most common): older adults, cardiovascular risk factors. Fibromuscular dysplasia (FMD): younger women; “string of beads” appearance. Pathophysiology: ↓ Renal blood flow → ↑ renin → ↑ angiotensin II & aldosterone → vasoconstriction + sodium retention → hypertension. Persistent ischemia can lead to CKD and small, shrunken kidney on affected side. 2. History Resistant hypertension: uncontrolled on ≥3 antihypertensive agents. Onset clues: Sudden worsening of previously stable hypertension. New severe HTN in young woman (FMD). Medication-related clues: Acute rise in creatinine after starting RAAS blockade suggests RAS. Ischemic kidney symptoms: recurrent flash pulmonary edema (“Pickering syndrome”). Atherosclerotic risk factors: smoking, hyperlipidemia, diabetes, PAD. 3. Exam Findings Hypertension: often severe or refractory. Abdominal bruit: systolic–diastolic bruit lateralized to one side (classic but not always present). Evidence of diffuse atherosclerosis: diminished peripheral pulses, carotid bruits. Signs of volume overload: edema, crackles (in episodes of flash pulmonary edema). 4. Making the Diagnosis Initial labs: May show elevated creatinine; BUN/Cr ratio variable. Possible reduced GFR in unilateral or bilateral disease. Urinalysis: typically bland (no significant proteinuria or hematuria). Imaging (high-yield order): Renal duplex Doppler ultrasound: first-line, noninvasive. CT angiography (CTA) or MRA: excellent anatomic definition; used if high suspicion. Conventional renal angiography: Gold Standard; definitive visualization but invasive. Clues on imaging: Atherosclerotic RAS: proximal narrowing. FMD: “string of beads” pattern in mid-distal renal artery. Functional clue: rise in creatinine after RAAS-modulating therapy. 5. Management (Exam Concepts) General principles: Blood pressure management conceptually; avoid nephrotoxins; adjust renally cleared drugs. Optimize cardiovascular risk reduction (atherosclerotic disease is systemic). Atherosclerotic RAS: Many cases managed with medical therapy; revascularization considered in select cases. Indications for revascularization (exam-level): Recurrent flash pulmonary edema. Refractory hypertension despite optimal therapy. Progressive kidney dysfunction with suspected bilateral RAS or RAS in a solitary kidney. FMD: Percutaneous angioplasty considered effective (exam concept; no procedural details). Monitoring: Renal function, BP trends, cardiovascular complications. Referral: nephrology or vascular specialists for diagnostic confirmation, intervention decisions, or unclear cases. QUESTION A 68-year-old man with a history of coronary artery disease and peripheral vascular disease presents for evaluation of worsening hypertension. His blood pressure remains elevated despite taking amlodipine, lisinopril, and hydrochlorothiazide. He recently developed dyspnea and leg swelling, and was hospitalized twice in the past month for flash pulmonary edema. He does not have diabetes. On exam, blood pressure is 172/94 mmHg, and a systolic–diastolic bruit is heard over the right upper abdomen. Serum creatinine has increased from 1.2 to 2.0 mg/dL over the past month. Which of the following is the most appropriate next step in evaluation? A) Renal biopsyB) Renal duplex Doppler ultrasoundC) 24-hour urine protein measurementD) Serum ANA and complement levels
