| Popis: | I N RECENT YEARS many papers have appeared dealing with the clinical and hemodynamic changes associated with surgical correction of congenital heart disease. However, very little information is available concerning the radiographic and angiographic changes following corrective or palliative cardiac surgery. It is the purpose of this communication to fill in this gap and emphasize the importance of cardiovascular radiology in the postoperative management of these patients. Only the most important cardiac defects will be discussed, The postero-anterior (PA) and lateral film of the chest with the barium-filled esophagus is one of the simplest, most important noninvasive technique to follow these patients. Hemodynamic changes, chamber enlargement, and complications of surgery may be visualized leading to a more definitive diagnosis by angiocardiography. Radiographic observations which can be readily made on follow-up chest examinations are concerned with: (1) changes of the thoracic cage, (2) the change in cardiac configuration due to alteration of chamber size, (3) changing left atrial size, (4) decrease or increase of central or peripheral pulmonary arteries, and (5) changing appearance of the mediastinum. Follow-up roentgenograms are useful for comparison only if all technical factors are kept constant. 1-6 Attention should be paid to the position of the diaphragm which may significantly alter the radiographic size of the cardiac silhouette and the appearance of the vasculature. This factor alone is more important than the measurement of the cardiac-thoracic ratio which is conveniently used in follow-up examinations to determine heart size. 7,s Overexposure and underexposure should be strictly avoided. |
