Gray scale Trans-Abdomino-Thoracic Ultrasonography in Evaluation of Dengue Hemorrhagic Fever

Abstract

Objective: To evaluate ultrasound findings in Dengue Haemorrhagic Fever (DHF) and further to predict severity of DHF. Study design: Cross sectional study. Settings: Allied Hospital Faisalabad. Duration of study: 1^st July 2011 to 30^th November 2011. Sample size: 50 Patient. Material and Methods: Ultrasound was performed on 50 patients of ages between 6-59 years with clinical suspicion of DHF. Serological tests IgM and IgG on ELIZA were performed to confirm the diagnosis, ultrasound was done on 2^nd to 08^th day all confirmed serologically 50 positive of DHF. These 50 patient divided into two groups as DHF (Group-I) mild type 45 patients and severe type of DHF (Group-II) 05 Patient. Result: Group-I patients ultrasound revealed gall bladder wall thickening 86.6%, Pericholecystic fluid 44.4%,  hepatomegaly 26.6%, 17.7%, right pleural effusion 8.8%, left pleural     effusion nil and pancreatic enlargement 6.6%. In Group-II ultrasonography revealed gall bladder wall thickening 100%,Pericholecystic fluid 60.0%,  hepatomegaly 60.0%, splenomegaly 40.0%, ascites 60.0%, right pleural effusion 60.0%, left pleural effusion 20.0%, pericardial effusion 20.0%, pancreatic enlargement 40.0% and 60.0% patient with fulminant hepatic failure. Conclusion: Trans-abdomino-thoracic sonography can be used as adjunct modality in patients with suspected DHF to detect early signs suggestive of the disease prior to obtaining serologic confirmation test results, especially in a dengue fever epidemic area and also useful tool to predict severity of the disease.
