Management of Lower Extremity Peripheral Arterial Disease with Endovascular Therapy

Introduction to Endovascular Therapy

For patients with peripheral arterial disease affecting the lower limbs, a comprehensive endovascular approach is recommended to establish in-line blood flow, minimize tissue loss, and preserve limb function, as suggested by the American Heart Association 1, 2

Selective Lower Limb Extremity (LLE) angiography is essential to evaluate the arterial network and plan appropriate interventions, especially when multiple arterial segments are involved, according to the European Society of Cardiology 3
Complete angiography down to the plantar arches is mandatory for proper assessment of the arterial network, particularly in cases involving infrapopliteal disease, as recommended by the European Society of Cardiology 3
Evaluation of lesion characteristics is useful in selecting the appropriate endovascular approach for treatment, as suggested by the American Heart Association 2

In patients with combined inflow and outflow disease, inflow lesions should be addressed first, as recommended by the American Heart Association 4
For patients with persistent symptoms after inflow revascularization, outflow revascularization procedures should be performed, according to the American Heart Association 4
A staged approach to endovascular procedures is reasonable in patients with ischemic rest pain, as suggested by the American Heart Association 2, 5

Atherectomy can be used for plaque removal in the superficial femoral artery (SFA), popliteal, and tibial vessels to improve luminal gain, as recommended by the American College of Cardiology 6
Stenting of the popliteal artery is appropriate when there is significant residual stenosis, flow-limiting dissection, or elastic recoil after angioplasty, according to the American Heart Association 2, 8
Percutaneous Transluminal Angioplasty (PTA) is recommended for establishing in-line blood flow to the foot, particularly in patients with nonhealing wounds or gangrene, as suggested by the American Heart Association 2, 5

Atherectomy of the anterior tibial vessel followed by PTA is appropriate for establishing in-line blood flow to the foot, as recommended by the American Heart Association 2, 3
The angiosome concept may be reasonable for patients with nonhealing wounds or gangrene, according to the American Heart Association 2, 8

Antiplatelet therapy should be administered after endovascular procedures to improve patency and reduce amputation rates, as recommended by the American College of Cardiology 6
Regular follow-up with duplex ultrasound is recommended to monitor patency and detect restenosis early, as suggested by the European Society of Cardiology 3
Additional supervised exercise therapy after percutaneous vascular intervention improves outcomes, according to the American College of Cardiology 9

For patients with critical limb ischemia (CLI), revascularization should be performed when possible to minimize tissue loss, as recommended by the American Heart Association 1, 2
An interdisciplinary care team approach is recommended for evaluation and comprehensive care for patients with CLI and tissue loss, according to the American Heart Association 2, 5
In patients with diabetes, optimal glycemic control is particularly important for improved limb-related outcomes, as suggested by the European Society of Cardiology 3

Restenosis remains a significant concern after endovascular interventions, particularly in complex lesions, as noted by the American College of Cardiology 6
The risk of distal embolization during atherectomy procedures must be considered, especially when treating heavily calcified lesions, according to the American College of Cardiology 6
Stent fracture is a potential complication in areas of high mechanical stress, such as the popliteal artery, as reported by the American College of Cardiology 7
Vessel perforation or rupture can occur during endovascular procedures, requiring immediate recognition and management, as recommended by the European Society of Cardiology 3
