Abstract

Spleen artery transposition (SAT) is an effective technique for arterial reconstruction in living donor liver transplant, especially when the recipient's hepatic artery is unsuitable for anastomosis. We report a case of a female 12-year-old with a diagnosis of acute liver failure/Wilson's disease who underwent living donor liver transplantation using the splenic artery transposition technique for hepatic artery anastomosis. Results: The arterial anastomosis time was 180 minutes, end-to-end anastomosis technique with a loop, 8/0 proline with interrupted sutures, and splenectomy. The ultrasound showed that the maximum systolic velocity was 43.8 cm/s, anastomosis was 35.3 cm/s, the resistive index was 0.77, and the systolic acceleration time was 40 ms. The operative time was 820 minutes, and there was no complication . The patient had no postoperative complication ; the hospital stay was 20 days, and the ultrasound follow-up showed normal hepatic artery flow velocity and no stenosis or thrombosis. Long-term follow-up of the patient 5 month post operation showed clinically stable, hepatic artery Doppler ultrasound flow Vmax 65cm/s, RI 0.59, SAT 65ms, no thrombosis. At the same time, we review the literature on the indications, technical characteristics, and results of this technique in Pediatric living donor liver transplantation. A splenic artery transposition is a feasible option for hepatic artery reconstruction in cases where the recipient's hepatic artery cannot be anastomosed conventionally.
