Friends, there is always some risk involved in any surgery. The risk involved in bypass surgery depends on many factors. Efficiency of the heart; condition of arteries; presence of diabetes or lungs related problems; status of blood supply to the brain; other serious illnesses such as weak functioning of kidneys; ability to exercise before operation; whether surgery is done in an emergency or a planned manner, etc. are the chief factors which decide the risk of surgery. Whenever the above-mentioned factors are favourable and if the surgery is carried out by a team of expert doctors in a good hospital, the overall risk is generally less than 2%-3% and is acceptable.
Few likely risk or problems seen during or within 3 – 10 days of the surgery :
- Infection at the site of operation and where stitches are taken
- Lung infection which may prolong ventilator requirement
- Paralysis or transient ischemic attack of brain
- Impairment of kidney function
- Increase/Decrease in heartbeats/Irregular heartbeats
- Heart attack – weakening of heart
- Weakening of bones/muscles
- Clotting of blood in the leg vein: Deep vein thrombosis
- Haemorrhage – need to give more blood transfusions
- Ulcer or Bed Sore in the back and on the hips
- Depression, anxiety and other psychological impairments
- Need to go for an emergency reoperation
