eTable 3. Recommendations for post-interventional follow-up.

	Recommendation grade	Evidencelevel
All patients should be given acetylsalicylic acid (100 mg) or clopidogrel pre-, peri-, and postinterventionally(/-op‧eratively). This treatment should be continued over the long term unless contraindicated.	A	1
After infra-inguinal endovascular treatment with stent implantation, it is recommended that ASA be given temporarily in combination with clopidogrel to improve the ‧patency rate.	B	GCP
Oral anticoagulant drugs should not be given after PTA of the femoropopliteal or tibial vessels.	A	1
For peripheral bypass procedures, the administration of platelet function inhibitors should be started preopera‧tively. They should continue to be given after surgical or hybrid procedures and should then be maintained over the long term unless contraindicated.	A	1
Patients with an infra-inguinal, femoropopliteal, or distal venous bypass should not routinely be given oral anticoagulant drugs (OACs).	A	2
The adminstration of OAC, or OAC together with ASA, can be considered in individual cases if the risk of bypass occlusion is very high.	0	2
Patients with PAOD should undergo regular clinical ‧follow-up with regard to the symptoms and signs of ‧PAOD (walking performance, pain at rest, trophic ‧disturbances).	B	3
Secondary prophylaxis against cardiovascular risk factors and treatment of cardiovascular comorbidities are indicated for all patients with PAOD, regardless of ‧whether their primary treatment was conservative, ‧medical, endovascular-interventional, or surgical.	A	1
Patients with PAOD who undergo invasive vascular ‧procedures should have regular follow-up thereafter.	B	2
All PAOD patients should be offered structured vascular exercises under supervision as part of their basic treatment. This also applies over the long term after treatment with drugs, an endovascular intervention, or surgery.	A	2
Patients who have undergone major amputations should receive suitable prostheses and rehabilitation.	A	GCP
