Congenital absences of the iliac artery: a systematic review of clinical presentations and anatomical patterns, with case illustration

Key Points

• To analyze clinical presentations and anatomical patterns of congenital iliac artery absences.
• Conducted a systematic review of existing literature on iliac artery anomalies.
• Examined case reports for clinical presentations and surgical implications.
• Categorized anatomical variations observed in the iliac arterial system.
• Identified multilevel congenital anomalies associated with ischaemia.
• Noted that isolated agenesis can be clinically silent and compensated.
• Emphasized the need for awareness in surgical contexts to prevent complications.
