Liver transplantation is the gold standard treatment for patients with end-stage liver disease [1, 2, 5]. Although vascular complications are rare among post-transplant complications, they remain the most feared and severe cause of graft failure since they compromise the blood flow of the transplant (either inflow or outflow). Early detection and treatment probably make the difference between not only graft survival or failure but also patient survival or death [1,3, 4, 5]. Doppler Ultrasound (DUS) after liver transplantation is a non-invasive method that allows a...

Patient population: A retrospective study of patients who had undergone liver transplant at our institution, was performed between November 2015 and September 2019. 310 consecutive patients were evaluated during that period and 2.170 DUS studies were analyzed. Data acquisition: DUS was performed in the OR; within two hours after surgery in the intensive care unit, and every 24 hours within the first 5 days after transplantation. All of them were made with an esaote-MyLab ™Alpha portable sonographer, and a 3.75 Mhz transducer. Resistive index (RI)...

Ten patients (3.22 %) out of 310 showed absent flow in the hepatic artery in the first post-transplant DUS, thus they underwent angiography or surgery. Patients with confirmed hepatic artery thrombosis were excluded. 300 patients (96.77%) showed patent hepatic artery. 198 out of 300 (66 %) patients demonstrated normal RI, 8 of them had low PSV that normalized on the third or fourth day post transplant. 102 patients out of 300 (34%) showed high RI. 96 patients out of 102 (94.11%) showed high RI together...

The purpose of this study was to assess close follow-up with Doppler ultrasonography in liver transplant recipients, highlighting on the ability and reproducibility of these two parameters, the persistent high RI together with a decrease in PSV, in the splenic artery steal syndrome diagnosis. In conclusion these preliminary results clearly show that persistent high RI followed by a decreased peak systolic velocity in the hepatic arterial blood flow after liver transplantation can be useful and reproducible to diagnose splenic artery steal syndrome.
