A series of clinical scenarios highlight various classic presentations of cardiothoracic and vascular diseases. For each patient presentation described below, identify the correct diagnosis by matching it to the corresponding surgical pathology.
- A 62-year-old man presents with cramping pain in his right calf after walking two blocks, which resolves after 5 minutes of rest. His right ankle-brachial index (ABI) is 0.75.Peripheral arterial disease
- A 71-year-old woman with chronic atrial fibrillation presents with the acute onset of excruciating left lower extremity pain, pallor, and an inability to move her toes. Pulses are absent below the femoral artery.Acute limb ischemia
- A 68-year-old man with a history of coronary artery disease presents with sudden, severe diffuse abdominal pain. His abdomen is soft and non-tender to palpation despite his evident distress.Acute mesenteric ischemia
- A 34-year-old man with Marfan syndrome presents with the sudden onset of tearing chest pain that radiates to his interscapular region. Physical examination reveals a new decrescendo diastolic murmur.Acute aortic dissection
Answer
The correct matches align the exertional calf pain with peripheral arterial disease, the sudden pulseless pale leg with acute limb ischemia, the pain out of proportion to abdominal exam with acute mesenteric ischemia, and the tearing chest pain in Marfan syndrome with acute aortic dissection.
Each clinical vignette provides highly specific, classic features for the respective vascular or cardiothoracic pathology: intermittent claudication for PAD, the '6 Ps' for acute limb ischemia, pain out of proportion to exam for mesenteric ischemia, and tearing pain with a new diastolic murmur for aortic dissection.

Key Concept
Recognizing the classic clinical presentations of major cardiothoracic and vascular surgical emergencies and chronic conditions is essential for prompt and accurate management.
