Maybe you found out you have liver hemangioma by chance during a medical checkup or other imaging examinations such as ultrasound or CT, which makes you worried and confused in this era of “tumor”. So what exactly is hepatic hemangioma and do you need treatment for it? Let’s talk about it today. First of all, hepatic hemangioma is not a real tumor, it is a tumor-like growth caused by abnormal development of blood vessels during human development. In other words, hepatic hemangioma is a benign lesion and does not become malignant. Hepatic hemangiomas can occur at any age, but often present as a symptom in adults and are more common in women. Hepatic hemangiomas account for 0.5% to 1% of routine physical examinations. Recently, due to the widespread use of ultrasound in clinical practice, the detection rate of hepatic cavernous hemangiomas has been greatly improved, especially for many asymptomatic hemangiomas. The disease can be solitary or multiple, and can occur in both the left and right hepatic lobes. Tumors vary in size, with more than 95% of hepatic hemangiomas being small, no more than 3 cm in diameter, and small ones can be diagnosed only under the microscope, while large ones can weigh more than 10 kg. The disease progresses slowly and can last for years to decades. The main risks may include: 1) upper abdominal discomfort, abdominal distension, abdominal pain, nausea, gas, etc., when the tumor gradually increases or compresses the stomach or intestines; 2) life-threatening abdominal hemorrhage due to rupture of a large hemangioma located on the liver surface; 3) liver pain and psychological stress. Although most hepatic hemangiomas are detected by ultrasound, the final diagnosis and localization depend on CT. Since the growth rate of hepatic hemangiomas cannot be measured, the need for surgical treatment of this disease is still controversial. It is generally accepted that larger hepatic hemangiomas smaller than 4 cm, which do not cause clinical symptoms or are not severe, can be followed up regularly without surgical removal. Treatment is required if: 1) the nature of the hepatic hemangioma is difficult to distinguish from other hepatic occupying lesions, especially in combination with positive hepatitis virus indicators or a history of chronic liver disease; 2) hepatic hemangiomas with clinical manifestations, such as abdominal pain, adjacent organ compression, and kasabach-Merritt (abnormal platelet consumption) syndrome; 3) hemangiomas with significant growth rate; 4) hemangiomas >10 cm; 5) hemangiomas in young women 5.Large hepatic hemangioma in young women: hepatic hemangioma has the characteristics of accelerated growth during pregnancy and the risk of rupture and hemorrhage during childbirth; 6.Special occupations: for those who are engaged in strenuous sports or enthusiasts, such as boxing, soccer, etc., huge hepatic hemangioma that may cause liver trauma can be considered for surgical resection; 7.Hemangioma occurring in the periphery of the liver, with the tip growth, complex risk areas Surgery for hemangioma should be relatively aggressive; 8. However, surgery should be cautious for patients over the age of 60, and no surgery should be performed without obvious symptoms. The main treatment methods of hepatic hemangioma are: 1. Hemangioma debridement is gradually becoming the mainstream of surgery with the advantages of less trauma, less damage to normal liver and less complications. For hepatic hemangiomas close to the liver envelope, laparoscopic surgery can be used with less trauma and faster recovery of the patient. Hepatic arterial vascular interventions have uncertain efficacy, are prone to recurrence, have the potential for serious biliary complications, and are only used for patients whose extensive hemangiomas are no longer amenable to surgical resection.
