Description
Introduction: Coronary artery disease is the leading cause of death worldwide and is an indication for bypass treatment. In most cases, a double, triple, or quadruple bypass grafting surgery is performed to resolve obstructed arteries. The arteries most commonly obstructed are the right coronary (RCA), left circumflex (LCA), and left anterior descending artery (LAD). Additionally, the arteries commonly used to create the bypass graft include the internal thoracic arteries and the great saphenous vein. Quintuple bypass grafting is rare, as five revascularizations, including revascularization of small vessels, are required in order to reroute blood flow around the extensive obstruction of the myocardial arteries.
Objective: The primary objective of the study is to present the anatomical findings and clinical significance of a quintuple bypass graft of a cadaver.
Methods: Routine dissection was performed during gross anatomy lab. Pictures were then obtained of the five bypasses.
Results: The posterior descending artery (PDA) branched off the RCA, which indicates that the heart was right dominant. The five arteries obstructed are the right and left conal arteries, LAD, PDA, and the circumferential artery. Extensive myocardial scarring was reported.
Conclusion: Quintuple bypass grafting is a uncommon surgical procedure performed when five obstructed arteries significantly reduce perfusion to the heart. Bypasses are fairly common. Typical patients have one to four bypasses. Five bypasses is relatively uncommon. The need for five grafts displays the severity of the atherosclerosis that could be the effect of the underlying condition. Although more grafting is required and the surgery is more complex, the outcome is relatively the same as with a double, triple, or quadruple bypass, in that it improves perfusion and longevity.
