[Transluminal exclusion of a subclavian artery aneurysm with stent-graft implantation]

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Aneurysms of the proximal left subclavian artery are rare but can lead to serious complications.
• Patients with generalized atherosclerosis often have multiple vascular comorbidities, including coronary artery disease and aortic aneurysms.
• Treatment options for subclavian artery aneurysms can be challenging, especially in patients with complex vascular disease.

Purpose of the Study:

• To report the successful exclusion of a proximal left subclavian artery aneurysm using a JOSTENT-Peripheral stent graft.
• To evaluate the mid-term outcome and safety of this endovascular approach in a patient with extensive atherosclerosis.

Main Methods:

• A 73-year-old male patient with atherosclerosis, infrarenal abdominal aortic aneurysm, renal artery stenosis, and coronary artery disease underwent endovascular repair.
• A JOSTENT-Peripheral stent graft was implanted to exclude the proximal left subclavian artery aneurysm.
• Follow-up included angiography, intravascular ultrasound, and computed tomography.

Main Results:

• The JOSTENT-Peripheral stent graft successfully excluded the aneurysm.
• Angiography at 6 and 12 months demonstrated an excellent outcome with complete exclusion.
• Intravascular ultrasound revealed no significant neo-intimal hyperplasia within the stent.
• Computed tomography confirmed complete thrombosis of the excluded aneurysm.

Conclusions:

• Endovascular exclusion of proximal left subclavian artery aneurysms with JOSTENT-Peripheral stent grafts is a safe and effective option.
• This approach offers a viable alternative in patients with complex vascular disease, avoiding open surgical repair.
• Mid-term follow-up confirms durable exclusion and favorable stent graft performance.
