Countercurrent aortography via the left brachial artery is safe and effective for evaluating thoracic aorta conditions in infants and young children. This diagnostic imaging technique successfully assessed systemic-pulmonary anastomosis and aortic coarctation in multiple cases.

Area of Science:

  • Pediatric Cardiology
  • Diagnostic Imaging
  • Vascular Surgery

Background:

  • Congenital heart defects and thoracic aorta abnormalities require accurate diagnostic methods in pediatric patients.
  • Traditional imaging techniques may have limitations in visualizing complex thoracic vasculature in young children.

Purpose of the Study:

  • To evaluate the safety and utility of countercurrent aortography through the left brachial artery in pediatric patients.
  • To assess the effectiveness of this technique in diagnosing conditions such as systemic-pulmonary anastomosis, aortic coarctation, and vascular rings.

Main Methods:

  • Countercurrent aortography was performed via the left brachial artery in 8 children.
  • Patient age ranged from 27 days to 42 months.
  • The procedure focused on assessing the thoracic aorta and related structures.

Main Results:

  • Systemic-pulmonary anastomosis was assessed in 3 out of 4 cases, including a 42-month-old child.
  • Aortic coarctation was evaluated in 3 patients.
  • An anomalous right subclavian artery was identified in a case with suspected vascular ring.

Conclusions:

  • Countercurrent aortography through the left brachial artery is a safe and valuable diagnostic tool for pediatric thoracic aorta conditions.
  • The technique is effective even in older children up to 42 months of age.
  • It aids in the diagnosis of various congenital abnormalities involving the thoracic aorta.
