A lethal case of massive hemorrhage after percutaneous liver biopsy in a patient with thrombasthenia.

Percutaneous needle liver biopsy is an important procedure in the diagnosis of and assessment of the severity of liver diseases. Although liver biopsy is considered to be a relatively safe procedure, there are occasional cases of death due to massive bleeding after liver biopsy. Thrombasthenia is a disease in which bleeding occurs in the mucosa and skin due to platelet dysfunction. A 60-year-old female was admitted for a liver biopsy for further investigation after an abnormal liver function test. She was diagnosed with thrombasthenia and was being treated with oral tranexamic acid and carbazochrome. Blood tests showed little decrease of platelet count and no abnormalities of blood coagulability. Approximately ten hours after the liver biopsy, the patient complained of nausea and lightheadedness, followed by decreased blood pressure and decreased consciousness. An emergent abdominal CT scan showed a large amount of blood in the abdominal cavity. The patient died despite multidisciplinary treatment, and a forensic autopsy was performed. At internal examination, approximately 2,620 mL of dark red blood was accumulated in the abdominal cavity. A puncture wound led 1.8 cm into the liver from the surface of the liver, and no major vascular damage was observed. The cause of death was considered to be blood loss due to bleeding from the puncture wound. Even if the platelet count is normal, such as in a case of thrombasthenia, the risk of bleeding should not be underestimated. Careful attention should be paid when performing liver biopsy in a patient with risk factors.
