Summary
Periacetabular osteotomy (PAO) is a hip surgery for acetabular dysplasia. A rare complication of PAO is obturator artery injury, highlighting the risks associated with this reconstructive procedure.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Pelvic Anatomy
Background:
- Periacetabular osteotomy (PAO) is a common reconstructive surgery for acetabular dysplasia.
- The procedure involves complex osteotomies within the pelvic region.
Purpose of the Study:
- To report a case of obturator artery injury during periacetabular osteotomy.
- To highlight the potential vascular risks associated with PAO.
Main Methods:
- Case report of a middle-aged woman undergoing bilateral periacetabular osteotomy.
- Detailed description of the surgical procedure and complication encountered during the second hip surgery.
Main Results:
- The first periacetabular osteotomy on the right hip was uncomplicated.
- An injury to the obturator artery occurred during the periacetabular osteotomy on the left hip.
- The injury was localized to the medial base of the iliopectineal eminence.
Conclusions:
- Periacetabular osteotomy carries a risk of iatrogenic vascular injury due to the proximity of intrapelvic vascular structures.
- Awareness of potential complications, such as obturator artery injury, is crucial for surgeons performing PAO.
