Hepatectomy of cavernous hemangioma with constitutional indocyanine green excretory defect.

The constitutional ICG excretory defect with marked ICG retention in spite of other normal hepatic functions has not been so rare in Japan. However, there is no previous report of hepatectomy in a patient with this disease. We describe a successful case of hepatectomy for cavernous hemangioma with this disease and use of technetium-99m diethylenetriaminepentaacetic acidgalactosyl-human serum albumin ( 99m TC-GSA) liver scintigraphy as the preopera tive assessment of the liver functional reserve. In our case, ICGR15 was more than 55%, however, a modified receptor index obtained from 99 mTC-GSA liver scintigraphy was normal. Left lateral segmentectomy of the liver was performed without any perioperative complications. Hepatectomy of patients with the constitutional ICG excretory defect is possible if modified receptor index value obtained from 99m TC-GSA scintigraphy is within the normal range.
