Summary
Direct percutaneous embolization successfully treated a large posterior tibial artery pseudoaneurysm. This minimally invasive technique, using a two-needle approach, provided safe and precise control during the embolization procedure.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Pseudoaneurysms can arise after arterial interventions, such as thrombectomy for femoropopliteal bypass grafts.
- Posterior tibial artery pseudoaneurysms pose a risk of bleeding and limb ischemia.
Observation:
- A large pseudoaneurysm of the posterior tibial artery developed post-thrombectomy.
- The pseudoaneurysm was treated using a direct percutaneous embolization technique.
Findings:
- A two-needle approach (19-gauge for embolization, 22-gauge for contrast injection) was employed.
- This technique facilitated rapid and safe embolization.
- Precise angiographic control was maintained throughout the procedure.
Implications:
- Direct percutaneous embolization is a viable and effective treatment for posterior tibial artery pseudoaneurysms.
- The two-needle technique enhances safety and precision in embolization procedures.
- This approach offers a minimally invasive alternative to open surgery for managing post-interventional arterial complications.
