Anthony Geary, the eight-time Daytime Emmy winner best known for his role as Luke Spencer on the long-running soap opera General Hospital, died at 78 from complications related to a medical procedure.

According to NPR, Geary died as a result of complications stemming from a surgical procedure performed three days earlier.

The most common complications include:

Infections, such as surgical site infections, pneumonia, and UTIs

Breathing problems, including pneumonia or respiratory failure

Heart and circulation issues, like heart attacks, strokes, and blood clots

Wound problems, such as bleeding or slow healing

Other issues, including pain, nausea, kidney injury, sepsis, and bowel problems

Risk also depends on the type of surgery. Cardiac and upper gastrointestinal surgeries tend to carry higher complication rates, while procedures like orthopedic or breast surgery generally have lower risks.
