Journal Title: ​International Journal of Contemporary Medicine surgery and Radiology - Year 2018, Vol 3, Issue 2
Abstract
Introduction: Dengue virus infections are a significant threat to human populations particularly in the tropical and subtropical regions. This is mainly transmitted by Aedes aegypti mosquito from humans to humans. The main pathological mechanisms associated include thrombocytopenia, hemorrhagic diathesis with hemoconcentration. Our present study was aimed to study the Ultrasonographic features of chest and abdomen cases of dengue fever of all types during an outbreak prospectively. Material and methods: A prospective study for a period of one year was conducted during an outbreak after ethical committee approval. All the cases of dengue fever serologically diagnosed were evaluated for ultra sonogram abdomen and chest and findings were recorded. Platelet counts were estimated in all the cases and compared with findings recorded on ultra sonogram. Qualitative variables such as presence of various ultrasound findings were expressed as percentages and their association with platelet counts or ages were assessed through chi-square test and a p value <0.05 was considered significant. Results: Males were predominant in our study (59.26%) with male: female ratio of 1.45:1. Common age group of the study was 11-29 years. Gall ball thickness was the most common USG finding in our study (65.08%) followed by pleural effusion (49.21%). Gallbladder wall thickening was the most common finding in Group -2 and group-3 with around 71%. Ascites with hepatomegaly was the commonest in group -1 cases, Thickness of gall bladder wall with pleural effusion in Group -2 cases, spleenomegaly and hepatomegaly in Group – 3 and Group- 4 cases. Discussion: In our study, thickness of the gall bladder wall was the most sensitive finding and pleural effusion was the most specific finding. USG is a relevant and important tool for early detection of plasma leakage signs and helps in follow up of patients who have a risk to progress to DHF. GB thickening with or without polyserosistis in a febrile patient should suggest the possibility of Dengue fever during an epidemic outbreak.
