Aims and objectives

-To evaluate the donor stability after liver transplantation, liver regeneratio nmeasurements according to variables such as the mean liver regeneration , age, gender, and donation rate were evaluated using3D CT volumetry. - Safety prediction analysis of donor's liver

Methods and materials

Subject: - Thirty donors who underwent 3D volumetry using Mx View V3.52 (Philips Medical System, the Netherlands) before and after liver transplantation between 2011 and 2013 were analyzed. Protocol and CT parameter: - Scan equipment; CT scanner Brilliance 64CH(Philips Medical System, Netherand). - Portal phase of CT Hepato Biliary-CTA and Abdomen CT. Methods: -Their mean liver regeneration and liver regeneration rates by variable were analyzed. -To calculate their mean liver regeneration rate, the rate of increase of their mean liver volume and their regeneration rate...

Results

Average of liver regeneration rate: - The mean liver regeneration measurements showed improvements. The liver volume increase rate rose from 751.727 days postoperativelyto 9 38.631 month postoperatively, and to 1,217.85 16 months postoperatively ; and the mean regeneration rate was 88.53%. By age group: -The patients in their 10’s and 20’s showed an approximately 90% regeneration rate; those in their 30’s, 87.48%; and those in their 40’s to 50’s, 80.47%. By gender: -The female patients reported a 74.13% regeneration rate and the male patients, 66.88%1...

Conclusion

In this study, the differences in the liver regeneration measurements and variables were verified through 3D volumetry, which is a direct observation method. 3D volumetry is considered an excellent clinical method of estimating preoperative donor stability.
