Aims and objectives
Neurological complications are common in patients with end-stage liver disease or cirrhosis,
and they can occur at any time before and after the liver transplantation.
Extrapyramidal sign and hepatic encephalopathy could affect patients with poorly compensated cirrhosis or appear after transjugular intrahepatic portosystemic shunt positioning . During liver transplantation,
the cerebral blood flow (CBF) may be affected by hemodynamic changes associated with transplantation,
Methods and materials
Patient population Our retrospective cohort study was reviewed and approved by the Institutional Research Review Board (IRRB) of our institution,
and informed consent form was waived; however,
informed written consent to the MR was obtained in all patients. The data were collected analyzing retrospectively the MR exams performed from January 2014 to January 2017.
The study group comprised 19 patients (16 men,
3 women; age range 42-70 years,
mean age 57.9 ± 7.4 years).
The mean score of the...
The brain core temperature was successfullymeasured noninvasively in all patients before and after OLT using magnetic MR diffusion-weighted imaging thermometry technique. The mean ± standard deviation of the brain core temperature measured before and after OLT was respectively 38.67 ± 1.76 °C and 38.60 ± 0.99 °C (figure 2 and 3). There was no statistically significant difference between the estimated temperature before and after liver transplantation (P = 0.643,
risk of beta-error = 0.90).
The results of this study demonstrated that no significant difference in brain core temperature was found in patients before and after liver transplantation by using DWI thermometry. To the best of our knowledge,
no other study has previously investigated the brain core temperature using DWI thermometry in patients who underwent liver transplantation. Neurologic complications are relatively common after solid organ transplantation and are affecting up to 30% of liver transplant recipients...
