[Clinical practice of dual antiplatelet therapy after percutaneous peripheral arterial interventions in Germany].

BACKGROUND AND AIM
Guideline recommendations regarding antithrombotic treatment with two antiplatelet agents (dual antiplatelet treatment) after peripheral interventional procedures are vague due to missing data from clinical trials.


METHODS
212 vascular centres in germany were evaluated regarding dual antiplatelet treatment using a standardized questionnaire with differentiation of localisation of the treated artery and interventional methods being used.


RESULTS
89 (42%) questionnaires returned completed. Application and duration of dual antiplatelet treatment after peripheral interventional procedures were quite different regarding interventional methods used (PTA: percutaneous transluminal angioplasty, DCB-PTA: drug coated ballon, Stenting, DES: drug eluting stent, Atherectomy). Mean duration of dual antiplatelet treatment were: PTA iliacal/femoro-popliteal 0 month, crural 1 month; DCB-Intervention and stenting: iliacal 1 month, femoro-popliteal 1,5 months, crural 2 months; DE-stenting iliacal 1,5 months, femoro-popliteal/crural 3 months and after femoro-popliteal / crural atherectomy 1 month.


CONCLUSION
Data about dual antiplatelet treatment after peripheral interventional procedures are sparse.
