Vascular grafts in the elderly

Area of Science:

• Vascular Surgery
• Cardiovascular Disease
• Biomaterials

Background:

• Increasing life expectancy leads to a rise in symptomatic atherosclerotic occlusive disease.
• Prosthetic vascular grafts, commonly made of Dacron (knitted or woven), are crucial for treatment.
• Atherosclerotic disease classification by location guides surgical intervention.

Purpose of the Study:

• To review the classification and treatment of atherosclerotic occlusive disease.
• To highlight the role of prosthetic vascular grafts in managing the condition.
• To assess the benefits and risks of reconstructive vascular surgery in elderly patients.

Main Methods:

• Classification of atherosclerotic occlusive disease by anatomical location (coronary, brachiocephalic, abdominal aorta branches, terminal aorta/branches).
• Description of common surgical treatments: arterial bypass, carotid endarterectomy, aortofemoral bypass graft.
• Discussion of Dacron graft properties (knitted/woven) and aneurysm management (resection/graft replacement).

Main Results:

• Symptomatic atherosclerotic occlusive disease incidence is increasing.
• Dacron grafts are versatile, with porosity adjusted by knitting or weaving.
• Surgical interventions are tailored to disease location, including bypass and endarterectomy.
• Aneurysm repair typically involves resection and graft replacement.

Conclusions:

• Selected elderly patients with atherosclerosis can benefit from reconstructive vascular surgery.
• The risk associated with surgery is manageable in appropriately selected patients.
• Advancements in vascular grafts and surgical techniques improve patient outcomes.
