Lung perfusion scintigraphy in the diagnosis of peripheral pulmonary stenosis in patients after repair of Fallot tetralogy
open access
Abstract
MATERIAL AND METHODS: This study comprised 104 patients who underwent repair of TOF at ages from 5 months to 25 years. The patients have been followed up for from 4.2 to 25 years. On the basis of chest x-ray peripheral pulmonary artery stenosis was suspected in 11 patients, in 12 on the basis of echocardiography examination.
RESULTS: Lung perfusion scintigraphy has been performed on 87 patients. The disturbances in lung perfusion (mostly in the left lung) were show by means of lung perfusion scintigraphy in 43 (49%) of patients. In 27 of them heart catheterisation has been performed. Angiography revealed stenosis of the lung artery branch in 15/43 (34.9%) patients with abnormal perfusion lung scan and in 4/44 (9%) in patients with normal perfusion lung scan. Intervention procedures were carried out on 10 patients.
CONCLUSIONS: Lung perfusion scintigraphy may prove a valuable, non-invasive screening tool in the assessment of patients after TOF repair, although both false-negative and falsepositive results may happen. Therefore, it should play an auxiliary role together with other diagnostic modalities.
