To demonstrate diagnostic possibilities of volume CT scanning in infants and children with suspected of anomalous pulmonary venous return
(APVR) with tachycardia.
Methods and Materials
86 children at the age of 1 day to 21 months with different APVR were examined with 320-slice CT scanner for specification of anatomic type of disease.
Next protocol was used for scanning: volume scan mode,
collimation 0.5 mm x 320 [Fig.1] were used,
if necessary collimation was reduced,
tube voltage 100 kV,
tube current was calculated,
depending on body weight of the patient.
Non-ionic iodine contrast was injected at the dose of 1 ml per kilogram,
injection speed was 0,8-1,5 ml/sec.
Examinations were performed...
There were no complications during anesthesia and examination.
Scan time was 1-3 seconds.
Next type of anomalous pulmonary venous
return were revealed:
• Total anomalous pulmonary venous return (TAPVR) in 31 cases:
- Supracardiac in 14 cases [Fig.2];
- Cardiac in 8 cases [Fig.3];
- Infracardiac in 6 cases [Fig.4];
- Mixed pattern in 3 cases [Fig.5].
• Partial anomalous pulmonary venous return (PAPVR) in 55 cases:
- Supracardiac in 27 cases;
- Cardiac in 18 cases;
- Infracardiac in 6 cases;
- Mixed pattern...
CT scanning in volume mode is high specific and sensitive method for diagnostic of anomalous pulmonary venous return in patients with tachycardia.
