Summary
Primary stent placement is safe and effective for iliac artery chronic total occlusions (CTOs), showing similar patency and limb salvage rates compared to stenosis. However, complications like distal embolization and rupture require caution.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Interventions
Background:
- Iliac artery chronic total occlusions (CTOs) present a challenge in endovascular treatment.
- Primary stent placement is an alternative to surgical revascularization.
Purpose of the Study:
- To evaluate the technical and mid-term outcomes of primary stent placement for iliac artery CTOs.
- To compare these outcomes with stent placement for iliac artery stenosis.
Main Methods:
- Retrospective analysis of 114 limbs undergoing primary stent placement (24 CTOs, 90 stenoses).
- Assessment of primary patency, assisted primary patency, and limb salvage rates per Society for Vascular Surgery guidelines.
Main Results:
- 100% technical success (angiographic and intravascular ultrasonographic) in all limbs.
- Similar 2-year primary patency rates (91% CTO vs. 89% stenosis).
- No significant differences in assisted primary patency, limb salvage, or survival rates between groups.
Conclusions:
- Primary stent placement is a safe and effective treatment for iliac artery CTOs.
- Major complications (distal embolization, arterial rupture) are significant concerns in CTOs.
- Caution is advised during primary stenting for iliac CTOs due to potential complications.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
