Arteriography in club foot
Summary
Children with club feet often have abnormal leg artery development. Arteriography revealed the posterior tibial artery was dominant in most cases, with a hypoplastic anterior tibial artery, highlighting the need to protect the posterior tibial artery during surgery.
Area of Science:
- Pediatric Orthopedics
- Vascular Anatomy
- Medical Imaging
Background:
- Clubfoot is a common congenital foot deformity.
- Vascular anomalies can be associated with congenital clubfoot.
- Understanding arterial anatomy is crucial for surgical planning.
Purpose of the Study:
- To investigate the arterial anatomy of children with severe, untreated club feet using arteriography.
- To identify common patterns of vascular anomalies in clubfoot.
- To assess the implications of these findings for surgical correction.
Main Methods:
- Arteriography was performed on fourteen children (nineteen feet) with typical, severe, untreated club feet.
- Patients' ages ranged from 1.3 to 13.5 years.
- Arterial anatomy was analyzed, focusing on the posterior tibial and anterior tibial arteries.
Main Results:
- Only three of nineteen club feet exhibited normal arterial anatomy.
- Sixteen feet showed a dominant posterior tibial artery.
- The anterior tibial artery was hypoplastic, ending at the ankle, resulting in the absence of a dorsalis pedis artery.
Conclusions:
- Significant arterial anatomical variations are common in severe, untreated club feet.
- The posterior tibial artery is frequently the dominant vessel.
- Protecting the posterior tibial artery during operative correction is critical to avoid vascular complications.
