Evaluation of caudate and right hepatic lobes ratio in patients with Schistosoma mansoni using ultrasound in Al-Fao area

Caudate-right lobe ratio is used to assess the liver, usually in the setting of cirrhosis, caused by chronic liver disease, in which there is atrophy of the right lobe with hypertrophy of the caudate lobe. The study was done to assess the caudate to right hepatic lobe ratios in diagnosing cases with schistosomiasis. It was carried on 50 adult patients of known cases of schistosomiasis in Al-Fao area and 20 adult volunteers from the same area as control group, all were surveyed by ultrasound.Abdominal scanning was carried out; measurements were done for liver caudate right lobe ratio, portal vein wall thickness, portal vein caliber and spleen size following the international guide line for measurement, scanning and protocol. The study showed that the male were affected more than female with incidences 62%, 38% respectively. It also showed that the most affected patients were farmer worker with high incidence 64%. The study noticed the most affected patient were those in the age ranging between (31 -50) years with incidence 58%. The study concluded that Caudate/right lobe ratio has ability to detected change in the liver size, texture and complication caused by schistosomiasis, the ratio has proportional relation to the portal vein wall thickness, the portal vein caliber and the spleen size and has reversal relation to the liver size. The Caudate/right lobe ratio in coarse liver is more than 0.64 and in complication is more than 0.7. Measuring the caudate and right hepatic lobes ratio using ultrasound appear to have a great value in diagnosis patients with Schistosoma mansoni.
