What is the peri‑operative risk of non‑cardiac surgery in a 40‑year‑old woman with bilateral absent brachial and radial pulses, a normal echocardiogram, and no other comorbidities?

Perioperative Risk Assessment: Low Risk for Non-Cardiac Surgery

This 40-year-old woman with bilateral absent brachial and radial pulses but a normal echocardiogram and no other comorbidities can safely proceed with non-cardiac surgery, as she has no active cardiac conditions or clinical risk factors that would increase her perioperative cardiovascular risk.

Risk Stratification

Based on the 2014 ACC/AHA perioperative guidelines 1, this patient falls into the lowest risk category:

• No active cardiac conditions (unstable coronary syndromes, decompensated heart failure, significant arrhythmias, or severe valvular disease)
• No clinical risk factors from the Revised Cardiac Risk Index:
  • No history of ischemic heart disease
  • No history of heart failure
  • No cerebrovascular disease
  • No diabetes mellitus
  • No renal insufficiency
• Normal echocardiogram confirms no structural heart disease or valvular abnormalities

The Absent Pulses: A Critical Distinction

The bilateral absent brachial and radial pulses are not a cardiac risk factor in this context. This finding suggests:

• Peripheral vascular abnormality (possibly Takayasu arteritis, subclavian steal, or congenital variant)
• Not indicative of coronary artery disease given the normal echo and young age
• Does not increase perioperative cardiac risk per ACC/AHA guidelines 1, 2

The normal echocardiogram effectively rules out significant cardiac pathology that would elevate surgical risk. The guidelines do not classify peripheral pulse abnormalities alone as clinical risk factors for perioperative major adverse cardiac events (MACE).

Management Approach

Proceed Directly to Surgery

According to the algorithmic approach 1:

1. Patients with no clinical risk factors should proceed with planned surgery regardless of functional capacity (Class I recommendation, Level of Evidence B)
2. No further cardiac testing is indicated - additional testing in low-risk patients provides no benefit (Class III recommendation) 3
3. Standard perioperative monitoring is sufficient - no need for invasive hemodynamic monitoring or ICU admission

Practical Considerations

Blood pressure monitoring caveat: Given absent upper extremity pulses, ensure:

• Blood pressure measurement via lower extremity cuff or arterial line in femoral artery if needed
• Document this requirement clearly in the anesthetic plan
• This is a technical monitoring issue, not a cardiac risk issue

Surgery-Specific Risk

The overall perioperative risk depends primarily on:

• Type of surgery (low-risk procedures like endoscopy carry <1% cardiac risk; intermediate-risk 1-5%; high-risk vascular surgery >5%)
• Surgical duration and blood loss potential
• Not on her cardiovascular status, which is essentially normal

What NOT to Do

Avoid unnecessary testing:

• No stress testing needed 3
• No coronary angiography indicated
• No additional echocardiography required (already normal within past year per guidelines 2)
• No cardiology consultation necessary for clearance

Do not delay surgery for cardiovascular evaluation in this low-risk patient - the guidelines explicitly recommend against this 1, 3.

Expected Outcomes

Based on contemporary data 4, patients without cardiovascular comorbidities undergoing non-cardiac surgery have:

• Mortality <1% for low-to-intermediate risk procedures
• Minimal risk of perioperative MI or heart failure
• Standard postoperative course expected

The absent pulses warrant vascular medicine evaluation at some point to determine etiology (especially to rule out inflammatory arteritis), but this should not delay necessary surgery and does not alter perioperative cardiac risk assessment.
