Practice questions on Vascular Pathology
50-year-old female, systemic sclerosis, right heart failure, PCWP normal, PVR markedly elevated. Vascular pathology MOST responsible?
- Pulmonary venous hypertension from left heart disease
- Pulmonary arteriolar intimal fibrosis and medial hypertrophy (PAH)
- Multiple pulmonary emboli causing mechanical obstruction
- Pulmonary interstitial fibrosis causing capillary destruction
- Pleuropericardial effusion compressing pulmonary vessels
Answer: B. - Normal PCWP + elevated PVR = **precapillary** pulmonary hypertension - In scleroderma, this is due to **PAH**-type small vessel remodeling: intimal fibrosis and medial hypertrophy of pulmonary arterioles (Group 1 PAH associated with connective tissue disease) ---
A 50-year-old female with systemic sclerosis (scleroderma) is found to have right heart failure on examination. Her PCWP is normal but PVR is markedly elevated. Which vascular pathology is MOST responsible for her pulmonary hypertension?
- Multiple pulmonary emboli causing mechanical obstruction
- Pulmonary venous hypertension from left heart disease
- Pulmonary arteriolar intimal fibrosis and medial hypertrophy (PAH)
- Pulmonary interstitial fibrosis causing capillary destruction
- Pleuropericardial effusion compressing pulmonary vessels ✅ Answer: C
Answer: A. Systemic sclerosis commonly causes pulmonary arterial hypertension (PAH) due to intimal fibrosis and medial hypertrophy of pulmonary arterioles, consistent with elevated PVR and normal PCWP.
