[Therapy of Peripheral Artery Aneurysms]

Area of Science:

• Vascular Surgery
• Radiology
• Medical Diagnostics

Background:

• Peripheral arterial aneurysms are rare vascular pathologies involving focal arterial dilatation.
• Popliteal artery aneurysms are the most common type, often associated with aortic aneurysms.
• These aneurysms are more prevalent in patients with connective tissue or autoimmune diseases.

Purpose of the Study:

• To review diagnostic modalities for peripheral arterial aneurysms.
• To discuss current therapeutic options, including open surgery and endovascular techniques.
• To evaluate the comparative outcomes of different treatment approaches.

Main Methods:

• Review of diagnostic imaging techniques: duplex sonography, CT angiography, MR angiography, and digital subtraction angiography.
• Analysis of therapeutic strategies: open surgical repair versus endovascular therapy.
• Examination of evidence from register and single-center studies, particularly for popliteal aneurysms.

Main Results:

• Precise mapping of aneurysm inflow and outflow is crucial for diagnosis and treatment planning.
• Endovascular therapy may offer comparable outcomes to open surgery in carefully selected popliteal aneurysm patients.
• Evidence comparing open and endovascular approaches is limited due to the rarity of the condition.

Conclusions:

• Open surgery remains the established gold standard for treating peripheral arterial aneurysms.
• Therapeutic decisions must be individualized, considering aneurysm morphology, location, vascular runoff, and patient condition.
• Further research is needed to establish definitive evidence for endovascular therapy in specific patient cohorts.
