دور الامواج فوق الصوتية في تشخيص و تحديد طبيعة الانصباب الجنبي مقارنة بالصورة البسيطة للصدر

This study was performed at Al-Assad University Hospital in Lattakia between 2005-2007. The study included /125/ pleural effusion cases. Transudates were anechoic, whereas an anechoic effusion could be either a transudate or an exudate. Pleural effusions with complex septated, complex nonseptated , or homogeneously echogenic patterns were always exudates. Homogenous hyperechoic effusions were due to hemorrhagic effusion or empyema. Ultrasound advantages in diagnosing subpulmonary effusions with small amount which may not be diagnosed on the radiograph, and ultrasound showed the possibility to define the nature of pleural effusion compared with chest plain radiograph. Ultrasound helps in differentiation between pleural effusion and pleural fibrosis.
