The patient's peripheral pulses show ______ delay between the radial and femoral pulses, suggesting aortic coarctation.

1 radio-femoral ✓ 정답
2 arterial
3 temporal
4 pulse
5 conduction

해설

Radio-femoral delay is a characteristic finding in aortic coarctation, where there is a noticeable time difference between the radial (arm) and femoral (leg) pulses. This delay occurs due to narrowing of the aorta, which impedes blood flow to the lower body.

임상 시나리오

Aortic Coarctation:
- Congenital narrowing of aorta, typically near ductus arteriosus
- Clinical findings:
* Radio-femoral pulse delay
* Upper extremity hypertension
* Lower extremity hypotension
* Weak/absent femoral pulses
* Systolic murmur
- Associated conditions:
* Bicuspid aortic valve (50-80%)
* Turner syndrome
* VSD, PDA
- Complications:
* Left ventricular hypertrophy
* Heart failure
* Aortic rupture
* Cerebral hemorrhage
- Diagnosis:
* Chest X-ray: Figure-3 sign
* Echocardiogram
* MRA/CTA
- Treatment:
* Surgical repair
* Balloon angioplasty
* Regular follow-up
