Summary
Traumatic pseudoaneurysms after total knee arthroplasty can cause hemarthrosis. Angiography and minimally invasive embolization techniques effectively treated these pseudoaneurysms without surgery, preventing recurrence.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Radiology
Background:
- Traumatic pseudoaneurysms are rare but serious complications following total knee arthroplasty.
- Early diagnosis and intervention are crucial to prevent significant morbidity.
Observation:
- Two patients presented with hemarthrosis and a pulsatile mass after total knee arthroplasty.
- One patient developed symptoms one month post-arthroplasty, while the second required evacuation of hemarthrosis prior to angiography.
Findings:
- Both pseudoaneurysms were successfully treated using minimally invasive endovascular techniques.
- Percutaneous thrombin injection and transcatheter embolization were utilized, avoiding surgical repair.
- No recurrence of hemarthrosis was observed during follow-up periods up to 24 months.
Implications:
- Angiography is a valuable diagnostic tool for evaluating hemarthrosis in reconstructed joints.
- Embolization techniques offer a safe and effective alternative to surgery for managing post-arthroplasty pseudoaneurysms.
- These minimally invasive approaches can improve patient outcomes and reduce recovery time.
