Fifty-four patients with hepatocellular carcinoma underwent LDLT. ID was classified as mild, moderate, or severe, and this classification was based on the extent of intimal injury. Mild, moderate, or severe ID were defined as ID that was less than one-quarter of the circumference of the HA, had reached one-half of the circumference of the HA, or was more than one-half of the circumference of the HA or involved the entire vessel wall, respectively. The reconstructive methods were based on the severity of ID encountered. Forty patients underwent TAE before LDLT, and 23 of these patients (57.5%) had ID. Nine patients had mild ID, 6 had moderate ID, and 8 had severe ID. In the 14 patients who did not undergo TAE, 4 had ID (28.6%; 3 mild and 1 severe). The other 10 patients (71.4%) had normal HA. In mild and moderate ID, the native HA was used after trimming of the HA until a healthy segment was encountered. In severe ID, the HA was reconstructed with alternative vessels. Two HA thromboses occurred postoperatively. TAE increased the risk of developing ID 2-fold. There was no graft loss or mortality in this series due to HA complications. In conclusion, ID of the HA is associated with pretransplant TAE among hepatocellular carcinoma patients undergoing LDLT. Intraoperative recognition of this complication and trimming until good vessel quality is encountered or using alternative vessels are important.
