Authors

Single case highlights collateral patterns in coarctation; leaves open correlation with modern noninvasive imaging.

To investigate the collateral circulation in a patient with aortic coarctation and associated complications.
Studied a patient diagnosed with aortic coarctation in 1938 who later presented with subarachnoid hemorrhage.
Injected the arterial system with barium paste.
Took a series of radiograms post-mortem to analyze collateral circulation.
Identified significant collateral circulation patterns in the aortic coarctation case.
Provided insights into the physiological adaptations of the circulatory system in the presence of aortic coarctation.

Population

1 patient with coarctation of the aorta who died from subarachnoid hemorrhage (from a series of 13 patients)

Intervention

Post-mortem injection of the arterial system with barium paste and radiography

Outcome

Anatomical description of the collateral circulation

Demonstrates the collateral circulation in coarctation of the aorta using post-mortem radiography.

Bramwell et al. (1941) studied this question.
