Introduction:

Portal cavernomatosis, typically secondary to portal vein thrombosis, causes portal hypertension, which can lead to gastrointestinal bleeding.

Objective:

To assess the usefulness of splenic elastography in children diagnosed with portal cavernomatosis.

Patients and Methods:

Field research, quasi-experimental, prospective, longitudinal study with a sample of 10 patients.

Results:

100% from socioeconomic stratum III. Equal sex distribution (50% each), with adolescents (early and late) accounting for 50% each. The mean age was 14.8 years (range 14-17 years, SD ± 1.03 years). All patients weighed over 36 kg, with a mean weight of 45.51 kg (range 35-58 kg, SD ± 9.17 kg). 80% had a height greater than 1.45 m, with a mean height of 1.55 m (range 1.35-1.8 m, SD ± 0.13 m). BMI was within the low and normal ranges for 50% of the patients. All patients had a chest circumference greater than 75 cm. 100% presented with large esophageal varices, and 100% had splenic elastography levels greater than 45 KPa. 80% exhibited moderate thrombocytopenia, and 100% had F0 liver fibrosis. 90% had hepatic steatosis S0. All patients showed low portal flow and splenomegaly, with 40% exhibiting hepatic elastography values between 80 and 100 KPa.

Conclusions:

Splenic elastography is a valuable tool in pediatric patients, with an average IQR/MED of 2.52 KPa. A result > 45 KPa serves as a non-invasive parameter and predictor of the risk of esophageal varices.
