RESUMEN
Positioning of central venous catheter (CVC) tip in the intrathoracic portion of superior vena cava (SVC) is essential during the surgical repair of superior sinus venous atrial septal defects (SVASD). Although tracheal carina is described as a radiological landmark for positioning the tip of CVCs, it may not be successful at all times. We describe a case of SVC type SVASD, where the SVC-right pulmonary artery crossing point imaged on transesophageal echocardiography was used as an echocardiographic landmark for optimal positioning of the CVC tip.

Bronchospasm in children is common; however, due to its sudden nature, radiographic correlation is uncommon. We planned a computed tomography (CT) coronary angiogram for a 5-year-old child for evaluation of Kawasaki disease. The child started to desaturate during the CT scanning after intravenous contrast injection under conscious sedation. CT scan documented spasm of trachea and bronchi, as well as crowding of ribs and elevated diaphragm during the event. Repeat CT scan documented well-aerated lung fields. The development of acute bronchospasm under anesthesia results in definite changes in the CT scan of the thoracic cavity as evidenced by this incident.
