[Percutaneous aspiration thrombectomy in the popliteal and calf area--a 4-year experience]
Insights
Percutaneous aspiration thrombectomy (PAT) is effective for treating iatrogenic embolizations and as an adjunct to thrombolysis. This method shows promise for acute distal popliteal artery occlusions.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Endovascular Therapy
Background:
- Peripheral artery disease (PAD) encompasses conditions like embolization and occlusions.
- Percutaneous aspiration thrombectomy (PAT) is an endovascular technique for clot removal.
- Iatrogenic embolization can occur as a complication of angioplasty.
Purpose of the Study:
- To evaluate the efficacy of PAT in treating popliteal and tibioperoneal artery embolizations.
- To assess PAT's outcomes in primary PAD, iatrogenic embolization, and during intraarterial thrombolysis.
Main Methods:
- Retrospective analysis of 41 patients (42 arteries) undergoing PAT.
- Antegrade approach via the common femoral artery.
- PAT performed primarily, after iatrogenic embolization, or during thrombolysis.
Main Results:
- Overall success rate of 67% for PAT.
- PAT achieved 88% success in iatrogenic peripheral embolizations.
- Success rates varied: 50% for primary PAD, 40-50% during thrombolysis, with no major complications.
Conclusions:
- PAT is highly effective for iatrogenic embolizations post-endovascular procedures.
- PAT serves as an effective accessory method with intraarterial thrombolysis.
- PAT is a viable primary treatment for acute distal popliteal artery occlusions.
Purpose:
Retrospective analysis of results of percutaneous aspiration thrombectomy (PAT) in the popliteal and tibioperoneal arteries in patients with primary and iatrogenic peripheral embolization and during intraarterial thrombolysis.
Material And Method:
Percutaneous aspiration thrombectomy was used in 41 patients (42 arteries). In 12 cases this method was used as the first choice in treatment of the peripheral artery disease, in 14 cases during intraarterial thrombolysis and 16 times after iatrogenic embolization secondary to balloon angioplasty. An antegrade approach to the common femoral artery was performed in all cases. In 40 patients the aspiration thrombectomy was performed from the popliteal region and proximal parts of tibioperoneal arteries.
Results:
Overall success (n = 42) was achieved in 67%, partial success in 23%. Aspiration thrombectomy was unsuccessful in. 10%. PAT was successful in 88% after iatrogenic peripheral embolization (n = 16), in patients during thrombolysis (n = 14) a good result was achieved in 40%, partial success in 50% and this method failed in 10%. Primarily performed aspiration thrombectomy (n = 12) in occlusion of peripheral arteries was successful in 50%. No major complications were recorded.
Conclusion:
PAT is a highly effective method in treatment of iatrogenic peripheral embolizations after endovascular procedures and effective accessory method in combination with intraarterial thrombolysis. This method can be used primarily in acute occlusion of distal popliteal artery.
