Summary
Mechanical failure of the Amplatz thrombectomy device (ATD) occurred during graft occlusion treatment. Awareness of ATD interactions with graft struts is crucial for safe thrombectomy procedures.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
Background:
- A 74-year-old woman underwent successful recanalization and implantation of a Dacron-covered Cragg endoprosthesis in the left superficial femoral artery for a 6-cm occlusion.
Observation:
- The endoprosthesis occluded 4.5 months post-discharge.
- An Amplatz thrombectomy device (ATD) was used for thrombectomy.
- The ATD experienced mechanical failure during the procedure, requiring complex extraction.
Findings:
- The ATD failure was likely caused by graft struts advancing into the device tip, breaking the drive shaft.
- Successful recanalization was ultimately achieved via percutaneous transluminal angioplasty and pharmacological thrombolysis.
Implications:
- Vascular surgeons and interventional cardiologists must be aware of potential interactions between thrombectomy devices and graft struts.
- This case highlights a rare complication that can occur during endovascular procedures involving thrombectomy devices and prosthetic grafts.
