How Long Is Bypass Surgery?

Published in Heart Surgery 2 mins read

Coronary artery bypass graft (CABG) surgery typically takes 3 to 6 hours to complete. However, the exact duration can vary based on several factors.

Factors Affecting Surgery Length

The primary factor influencing the length of bypass surgery is the number of arteries that need to be bypassed. Each bypass adds to the overall time. Other factors include:

  • Number of Bypass Grafts: The more blocked arteries requiring bypass, the longer the surgery.
  • Source of Graft Vessels: The preparation and harvesting of graft vessels from different locations (leg, chest, arm) can add time.
  • Patient's Overall Health: Underlying health conditions can influence the surgery's duration.
  • Surgical Technique: The specific approach used by the surgeon can affect the length of the procedure. This can include whether the surgery is performed on-pump or off-pump.
  • Complications: Unexpected complications during surgery can prolong the procedure.

Graft Vessel Sources

Surgeons use different blood vessels for bypass grafts. Common sources include:

  • Saphenous Vein (Leg): The most common source; harvesting it adds time to the surgery.
  • Internal Mammary Artery (Chest): Often preferred for its long-term patency.
  • Radial Artery (Arm): Another potential source of arterial grafts.

Summary

While the general timeframe for bypass surgery is 3 to 6 hours, it's essential to understand that this is an estimate. The actual duration depends on the complexity of the case and individual patient factors.
