What is the most appropriate action when a provider, specialized in treating perforated peptic and upper gastrointestinal (GI) problems, encounters a situation requiring vascular surgery expertise during an operation, but has not been trained in vascular subspecialties?

Immediate Vascular Surgery Consultation is Required

When a provider specialized in upper GI surgery encounters a vascular complication requiring subspecialty expertise they do not possess, the operation must not proceed with the untrained provider performing vascular surgery—even under supervision—as this violates fundamental principles of surgical competence and patient safety. 1

The Correct Action: Obtain Immediate Vascular Surgery Consultation

Why the Provider Cannot Perform Vascular Surgery Under Supervision

• Formal training requirements are explicit: Vascular interventions require completion of structured fellowship programs in cardiovascular medicine, radiology, vascular surgery residency after general surgery board certification, or vascular medicine fellowship after internal medicine board certification. 1

• Supervision does not substitute for training: The American College of Cardiology explicitly states that "the practice of peripheral angioplasty by the untrained physician should be avoided; it is risky and contrary to patient welfare and good medical practice." 1 This principle extends to all vascular procedures, not just endovascular interventions.

• Minimum procedural experience cannot be met intraoperatively: Training standards require at least 100 diagnostic peripheral angiograms and 50 peripheral procedures under supervision, with >50% performed as primary operator. 1 A single supervised case does not meet competency standards.

• Operator experience is critical for success: Multiple surgical societies emphasize that "operator experience is critical for success in any procedure" and that intracranial and peripheral vascular procedures should "only be performed by appropriately trained neurovascular interventionalists" or vascular specialists. 1

The Appropriate Algorithm

Step 1: Recognize the vascular complication requiring subspecialty expertise 2, 3

• Identify whether this involves major vessel injury, need for vascular reconstruction, or complex vascular exposure beyond the upper GI surgeon's training

Step 2: Immediately request intraoperative vascular surgery consultation 2, 3, 4, 5

• Studies demonstrate that vascular surgeons provide crucial operative support across multiple specialties, with 56% of consultations being unplanned emergencies 2
• Immediate recognition and consultation is associated with better outcomes; delayed recognition in vascular injuries has resulted in mortality in 3 of 8 patients in reported series 4

Step 3: The vascular surgeon performs the vascular component 2, 3

• The vascular surgeon provides the necessary vascular exposure, repair, reconstruction, or control 2
• This occurs in both planned and unplanned settings, with vascular surgeons effectively facilitating completion of nonvascular procedures even with significant intraoperative blood loss 2

Step 4: The upper GI surgeon completes their portion of the operation 2, 3

• After vascular issues are addressed by the appropriately trained specialist, the primary surgeon continues with their procedure

Why "Stopping the Vascular Surgery" is Also Incorrect

• Simply abandoning the vascular component when it becomes necessary for patient safety is not appropriate—the patient requires the vascular intervention 2, 3

• The solution is not to stop, but to obtain appropriate expertise 4, 5

Evidence from Real-World Practice

• A 3-year study found 76 intraoperative vascular surgery consultations across 12 surgical subspecialties, with 56% being unplanned emergencies 2

• Another study identified 299 patients requiring intraoperative vascular assistance, with 14.4% needing control of active hemorrhage and 19% requiring vascular reconstruction 3

• In laparoscopic vascular injuries, immediate vascular surgery consultation and conversion to open procedure with "appropriate vascular surgical techniques are required to reestablish arterial and venous continuity and minimize morbidity and mortality" 4

Critical Pitfalls to Avoid

• Never attempt vascular procedures without proper training: Even with supervision, this violates credentialing standards and puts patients at unnecessary risk 1

• Do not delay vascular consultation: In major vascular injuries during laparoscopic procedures, delayed recognition resulted in death in 3 of 8 patients, while immediate recognition led to recovery in most cases 4

• Ensure immediate availability: The high proportion of emergent cases requiring vascular repair demonstrates the importance of having vascular surgeons immediately available at the hospital 3

The answer is neither A nor B as stated—the correct action is to obtain immediate intraoperative vascular surgery consultation, allowing the appropriately trained vascular surgeon to perform the vascular component while the upper GI surgeon manages their portion of the operation. 2, 3, 4, 5
