What are the risks of this specific procedure?

There are risks and complications with this procedure.

General risks:

  • Infection can occur, requiring antibiotics and further treatment.

  • Increased risk in obese people of wound infection, chest infection, heart and lung complications, and thrombosis.
  • Heart attack or stroke could occur due to the strain on the heart.
  • Blood clot in the leg (DVT) causing pain and swelling. In rare cases, part of the clot may break off and go to the lungs.
  • Death as a result of this procedure is possible.

Specific risks:

  • The wound can be thickened and red as healing occurs and may be painful.
  • Further drainage may be necessary to open up other foci of infection.
