They are usually removed for cosmetic reasons if they grow very large or for histopathology to verify that they are not a more dangerous type of tumor such as a liposarcoma. This last point can be important, as the characteristics of a tumor are not known until after it is removed and medically examined.Lipomas are normally removed by simple excision. The removal can often be done under local anesthetic and takes less than 30 minutes. This cures the great majority of cases, with about 1–2% of lipomas recurring after excision. Liposuction is another option if the lipoma is soft and has a small connective tissue component. Liposuction typically results in less scarring; however, with large lipomas, it may fail to remove the entire tumor, which can lead to regrowth.New methods under development are supposed to remove the lipomas without scarring. One is removal by injecting compounds that trigger lipolysis, such as steroids or phosphatidylcholine. Other potential methods based on tissue-targeted heating include cauterization, electrosurgery, and harmonic scalpel. Post surgery
Patients who have a lipoma removed are usually able to return home the same day, without any need for hospitalization. Some patients may have pain, swelling, or bruising where the lipoma was removed. These symptoms usually subside after a few days. Resection of an intermuscular lipoma in the elbow region

Prognosis
Lipomas are rarely life-threatening, and the common subcutaneous lipomas are not a serious condition.
Hepatic artery thrombosis occurs when a blood clot forms in the artery that provides blood flow to the liver. Hepatic artery thrombosis may occur as a complication after liver transplantation, and represents the most common complication of liver transplantation. Smoking tobacco increases the risk of hepatic artery thrombosis in people who have undergone liver transplantation.Hepatic artery thrombosis may cause severe elevations in serum aminotransferases, alanine transaminase (ALT) and aspartate transaminase (AST). Often the AST is greater than the ALT. Hepatic artery thrombosis is usually diagnosed with ultrasound with doppler, although it may be diagnosed using computed tomography (CT) or magnetic resonance imaging (MRI). The treatment for recently developed or acute hepatic artery thrombosis include anticoagulant medications, fibrinolytic therapy to break up the blood clot, or surgical revascularization. If acute hepatic artery thrombosis occurs after liver transplantation, then retransplantation with a new liver may be necessary. Signs and symptoms
Hepatic artery thrombosis can cause severe elevations in serum liver enzymes, AST and ALT. Often the AST is greater than the ALT. When it occurs after liver transplantation, it usually develops within 4 months after surgery. Diagnosis
Hepatic artery thrombosis is diagnosed with ultrasound with doppler, which shows a lack of blood flow through the hepatic artery. Hepatic artery thrombosis may also be diagnosed using CT or MR imaging, which would show evidence of a blood clot within the hepatic artery. Treatment
Treatment for acute hepatic artery thrombosis include anticoagulant medications, fibrinolysis therapies to break up the blood clot, or surgical revascularization.
