Insights

Radial artery grafts are common for coronary artery bypass, but harvesting can cause rare digital ischemia. Consider comorbidities like collagen vascular disease as contraindications for radial artery harvest.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Grafting Procedures

Background:

  • The radial artery is a frequently utilized graft in coronary artery bypass surgery.
  • While harvesting morbidity is infrequent, complications such as digital ischemia can arise post-operatively.

Observation:

  • This report details a case of delayed digital ischemia occurring after radial artery harvesting for coronary artery bypass grafting.
  • The patient's preoperative assessment did not indicate a risk for this complication.

Findings:

  • Digital ischemia can manifest late after radial artery harvest, even with normal preoperative vascular assessments.
  • The presence of comorbidities, specifically collagen vascular disease combined with atherosclerotic peripheral vascular disease, significantly increases the risk.

Implications:

  • Careful preoperative evaluation for comorbidities is crucial before radial artery harvest.
  • Collagen vascular disease and peripheral artery disease should be considered relative contraindications for radial artery harvesting.
  • This case highlights the importance of considering the cumulative risk factors in graft selection for coronary artery bypass surgery.
