Case:
The patient was a 61-year-old woman who underwent robotic-assisted total hip arthroplasty (THA) for left hip osteoarthritis. Postoperatively, the patient became hypotensive, and computed tomography angiography (CTA) demonstrated a retroperitoneal hematoma with active bleeding. An iatrogenic injury to the ascending branch of the deep circumflex iliac artery from a referencing pin was identified and managed with coiling.
Conclusion:
Referencing pin placement during robotic-assisted THA introduces the risk of iatrogenic injury to the ascending branch of deep circumflex iliac artery. Avoidance of referencing pin placement near the anterior superior iliac spine can decrease the risk of this complication.
