Difficulty: EasyCardiothoracic and Vascular Surgery

Match the following classic clinical presentations with their most likely vascular surgical diagnosis.

  • Sudden-onset of a painful, pale, pulseless, paresthetic, and cold lower extremityAcute limb ischemia
  • Triad of bilateral buttock claudication, erectile dysfunction, and absent femoral pulsesLeriche syndrome (Aortoiliac occlusive disease)
  • Sudden-onset, severe, tearing interscapular back pain with asymmetric upper extremity blood pressuresAcute aortic dissection
  • Asymptomatic pulsatile abdominal mass discovered incidentally in a 70-year-old male with a smoking historyAbdominal aortic aneurysm

Answer

Acute limb ischemia (painful/pale/pulseless leg), Leriche syndrome (buttock claudication/erectile dysfunction/absent femoral pulses), Acute aortic dissection (tearing back pain/asymmetric BP), and Abdominal aortic aneurysm (pulsatile mass in older smoker).
Each clinical presentation represents a classic 'textbook' description of a major vascular pathology. Recognizing these pathognomonic symptom clusters (such as the 6 Ps for acute limb ischemia, or the Leriche triad for aortoiliac occlusion) is a fundamental, entry-level diagnostic skill in vascular surgery.

Step-by-Step Solution

1
Analyze the first presentation: 'painful, pale, pulseless, paresthetic, and cold lower extremity'.
Matches the '6 Ps' of acute arterial occlusion.
These signs indicate sudden cessation of blood flow, requiring emergent intervention.
2
Analyze the second presentation: 'bilateral buttock claudication, erectile dysfunction, and absent femoral pulses'.
Matches the classic triad of Leriche syndrome.
This specific combination of symptoms indicates chronic aortoiliac occlusive disease.
3
Analyze the third presentation: 'tearing interscapular back pain with asymmetric upper extremity blood pressures'.
Matches the classic presentation of acute aortic dissection.
The nature of the pain and the pulse deficit are hallmarks of an intimal tear flap propagating down the aorta.
4
Analyze the fourth presentation: 'pulsatile abdominal mass in a 70-year-old male with a smoking history'.
Matches an unruptured abdominal aortic aneurysm.
Age, male sex, and smoking are the primary risk factors for AAA, which typically presents as an asymptomatic pulsatile mass.
