Patients with chronic hepatitis and cirrhosis are at high risk when an hepatectomy is performed.

There are always risks with any surgery, but a hepatectomy that removes 25–60% of the liver carries more than the average risk. Pain, bleeding,...

infection, and/or injury to other areas in the abdomen, as well as death, are potential risks. Other risks include postoperative fevers, pneumonia, and urinary tract infection. Patients who undergo any type of abdominal surgery are also at risk to form blood clots in their legs. These blood clots can break free and move through the heart to the lungs. In the lungs, the blood clot may cause a serious problem called pulmonary embolism, a condition usually treated with blood-thinning medication. But in some cases, embolisms can cause death. There are special devices used to keep blood flowing through the legs during surgery to try to prevent clot formation.

There are also risks that are specific only to liver surgery. During the preoperative evaluation, the treatment team tries to evaluate the patient's liver so that they can decide what piece can safely be removed. Removal of a portion of the liver may cause the remaining liver to work poorly for a short period of time. The remaining part of the liver will begin to grow back within a few weeks and will improve. However, a patient may develop liver failure.
