Case Report of Extensive Isolated Spontaneous Celiac Trunk Dissection After Liver Transplantation.

Arterial dissection is a rare complication after liver transplantation (LT). We report a case of extensive isolated spontaneous celiac trunk dissection (ISCTD) up to the proper hepatic artery, left gastric artery, and splenic artery after living donor liver transplantation. A 48-year-old woman with cryptogenic liver cirrhosis underwent living donor liver transplantation. Intraoperative and postoperative Doppler ultrasound revealed sufficient flow in the hepatic artery, portal vein, and hepatic vein. On postoperative day (POD) 10, Doppler ultrasound showed reduction of hepatic arterial flow. On POD 16, a contrast-enhanced computed tomography scan showed that the ISCTD extended to the proper hepatic artery, left gastric artery, and splenic artery with an entry tear on the proximal side of the celiac trunk. Although the computed tomography scan showed ischemia of a small part of the liver, blood flow to the liver was kept to some extent. Because all false lumens were occluded by thrombi and the liver enzyme levels normalized, we chose conservative therapy with antiplatelet agents. The patient was discharged on POD 53. She remains well without any liver dysfunction after 18 months with reduction in all false lumens and a patent hepatic artery. Several cases of ISCTD have been reported apart from LT, most of which were treated with conservative therapy. We conclude that conservative therapy could be the first choice in ISCTD even after LT.
