A Ruptured Popliteal Artery Aneurysm Treated with Coil Embolization

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Peripheral Arterial Disease

Background:

• Popliteal artery aneurysms are common peripheral arterial aneurysms.
• They can lead to limb-threatening complications like distal embolization and thrombosis.
• Rupture of popliteal artery aneurysms is an uncommon but serious event.

Purpose of the Study:

• To report a case of a nonfatal, painful rupture of a popliteal artery aneurysm with chronic outflow occlusion.
• To describe the successful endovascular management of this rare presentation.
• To evaluate the efficacy of coil embolization in excluding the aneurysm while maintaining collateral circulation.

Main Methods:

• Case report of a patient with a ruptured popliteal artery aneurysm and chronic outflow occlusion.
• Endovascular procedure involving coil embolization of the proximal popliteal artery.
• Assessment of aneurysm exclusion and preservation of collateral circulation post-procedure.

Main Results:

• Successful exclusion of the ruptured popliteal artery aneurysm was achieved with coil embolization.
• Collateral circulation was maintained post-procedure.
• The patient experienced no ischemic symptoms, such as intermittent claudication or pain at rest, after treatment.

Conclusions:

• Endovascular coil embolization of the proximal artery can be an effective treatment for ruptured popliteal artery aneurysms with chronic outflow occlusion.
• This approach successfully excluded the aneurysm and preserved limb perfusion.
• This minimally invasive technique may be a viable option for managing similar complex popliteal artery aneurysm cases.
