Figuring it all out

Today, I observed another CABG surgery, similar to the ones mentioned in previous posts. Dr. Patel used the left internal mammary artery to bypass the left anterior descending artery and the saphenous vein graft to bypass the obtuse marginal artery. However, in this case double sternal wires were used to close the patient's sternum after surgery rather than single sternal wires (pictured below). The double wires provide additional support.

Single sternal wires vs. double sternal wires


Each surgery is thrilling to watch from the first cut to the last stitch, and I am extremely grateful to be able to watch these open heart procedures. I am starting to realize what it is really like to be a cardiothoracic surgeon, from the crazy long procedures and work days to the fun conversations in the physicians dining hall and OR. Although it has only been two weeks, I have a much better understanding of the demands of the profession. Thankfully, my experiences with Dr. Patel have made me more excited to jump into the medical field. I am looking forward to the next nine weeks!

  1. Hey Shreya! I think you have a really fascinating project. Aside from this blog, I know nothing about open-heart surgery so I am wondering how exactly you can bypass the heart and still keep the blood circulating. Also, what is a vein graft?

    1. A heart-lung machine will reroute blood from the right atrium into the machine to get oxygenated and pumped back into the aorta to travel through the body via tubing. The machine basically takes over the function of the heart and lungs so the surgeon can operate on a still heart. Of course, the heart will continue beating when the machine takes over, so the perfusionist will administer cardioplegia solution (potassium) into the heart to stop it.
      A vein graft is simply a portion of the patient's own vein. In this case, a portion of the spahenous vein is taken from the patient's calf to use in bypass.
