Ultrasonographic pattern of plasma leak in dengue haemorrhagic fever.

OBJECTIVE

To note ultrasonographic findings used for diagnosing plasma leakage in dengue haemorrhagic fever patients.

METHODS

The observational retrospective study was conducted at the Holy Family Hospital, Rawalpindi and comprised records of patients with confirmed dengue infection who were screened for dengue haemorrhagic fever according to Dengue Expert Advisory Group criteria from July 1 to December 31, 2013. Each patient underwent ultrasonography for the detection of ascites, gall bladder wall thickness, pleural and/or pericardial effusion along with their quantification and localisation.

RESULTS

Of the 240 patients, 166(69.2%) were men. The overall mean age was 28.9±12.4 years. Of the total, 215(89.5%) had ultrasonographic abnormalities, suggestive of plasma leakage. Quantification and localisation wise, mild abdominal ascites 68(47.2%), right pleural effusion 82(74.5%) and mild pleural effusion 98(89%) were commonly noted. None had pericardial effusion.

CONCLUSIONS

Mild ascites and mild right pleural effusion were the commonest pattern of ultrasonographic leak in dengue haemorrhagic fever patients.
