A medical student is reviewing peripheral vascular cases on the surgical ward. For each specific clinical presentation and physical examination finding described below, identify the most accurate corresponding diagnosis or pathological syndrome.
- Ankle-brachial index of 0.3 with continuous, burning pain in the distal forefoot occurring primarily at night when supine.Critical limb ischemia
- Sudden onset of right leg pain, paralysis, and poikilothermia in a patient with atrial fibrillation, with no palpable popliteal pulse.Acute arterial thromboembolism
- Diminished femoral pulses bilaterally accompanied by erectile dysfunction and gluteal claudication in a patient with a heavy smoking history.Aortoiliac occlusive disease (Leriche syndrome)
- A localized pulsatile mass in the right groin with a continuous systolic-diastolic bruit and a palpable thrill following a recent cardiac catheterization.Femoral artery pseudoaneurysm
Cevap
The presentations correctly match with Critical limb ischemia, Acute arterial thromboembolism, Aortoiliac occlusive disease (Leriche syndrome), and Femoral artery pseudoaneurysm, respectively.
Each clinical scenario presents hallmark signs of distinct vascular pathologies. Rest pain with ABI below 0.4 indicates critical limb ischemia. The sudden onset of the '6 Ps' with an embolic source indicates acute arterial thromboembolism. The triad of claudication, diminished femoral pulses, and impotence defines Leriche syndrome. Finally, a pulsatile mass with a continuous bruit following arterial access is classic for a pseudoaneurysm.
