Evaluation of Caudate to Right Lobe Ratio of Liver among Sudanese Using Ultrasonography

Abstract

Caudate lobe was thoroughly investigated worldwide, and it size, appearance and relation with right lobe are popular subject to investigators and this was believed to be because it receives blood supply from both right and left portal veins and hepatic arteries. This was descriptive study aimed to determine the ratio between the caudate lobe and right liver lobe among Sudanese. 107 subjects were enrolled in the study, the liver should look sonographically normal. All patients were scanned with Real time Siemens G60s machine was used with curve linear 3.5 MHZ transducer probe. On transverse scan, the caudate lobe and the right lobe of the liver were measured by obtaining an axial image of the liver immediately below the bifurcation of the main portal vein. The study showed that the ratio in Sudanese ranging between 0.3 and 0.67, which was similar to the international ratio. Furthermore, there is no statistical difference between both gender measurements, and this is in term revealed that both caudate and right liver lobes were also comparable to their international measures. Considering a widespread discrepancy regarding the ultrasound findings in cirrhotic patients, the caudate lobe right lobe ratio can be a useful tool. The study has determined the normal ratio in our environment, there is a need for another study to determine the ratio among cirrhotic patients.
