Validitas Foto Thorax Proyeksi Posterio-Anterior untuk Menegakkan Diagnosis Emfisema Pulmonum
Abstract: Emphysema as a
condition of lung characterized by abnormal, permanent enlargement of airspaces
distal to the terminal bronchiole, accompanied by destruction of their walls.
At first chronic inflammatory induced changed the lung structure. The
abnormality of lung structure can manifest in Posterio-anterior chest X-ray.
Posterio-anterior chest X-ray has good validity to establish change the lung
structure. Posterio-anterior chest X-ray was a simple examination and cheap as
good as spirometry for a gold standard.
This study maintained to get validity of Posterioanterior chest X-ray to
establish diagnosis of emphysema.This
study is a diagnostic test were that
performed in Departement of Radiology RSUD Dr Moewardi Surakarta from July to
October 2008. Samples of this study recruited were 192 subjects with range of
age between 18-81 years old, 154 men and 38 women. emphysema was diagnosed if
Posterio-Anterior chest X-ray showed : 1)Hyperinflation 2) Hyperlucency 3)
Decrease and flattened of diaphragma and 4) T ear drop appearance of the heart,
to determine either emphysema or non emphysema. emphysema was diagnosed if met with all criteria above. Spirometry
showed obstruction with criteria of GOLD 2006, mild obstruction if FEV1/ FVC
< 70%, FEV1 > 80% predicted, moderate obstruction if FEV1/FVC < 70%,
50%< FEV1<80% predicted, severe obstruction if FEV1/FVC < 70%, 30%<
FEV1<50% predicted and very severeobstruction if FEV1/FVC < 70%, FEV1<
30% or FEV1<50% predicted plus chronic respiratory failure. From 192 subject sperformed Posterio-Anterior chest X-ray, 126 subjects
(66%) were diagnosed with emphysema and non emphysema were diagnosed in 66
subjects (34%). Posterio-Anterior chest X-ray emphysema with obstruction were establishe
in 117 subjects (93%) and non obstruction were diagnosed in 9 subjects (7%).
Posterio-Anterior chest Xray non emphysema with obstruction were diagnosed in
12 subjects (18%) and non obstruction were diagnosed in 54 subjects (82%).
Smoking habits was higher in emphysema Posterio-anterior chest X-ray group than
non emphysema group. The validity of Posterio-Anterior chest X-ray to establish
diagnosis of emphysema was 90.6% in sensitifity
and 84.3% in
spesifisity. Posterio-Anterior chest X-ray has good validity to establish diagnosis emphysema.
Posterio-anterior chest X-ray was a simple examination and cheap as good as
spirometry for a gold standard.
