Popliteal arterial aneurysms.

Aneurysms are associated with significant complications if not diagnosed and managed appropriately. Popliteal arterial aneurysms are the most common peripheral aneurysm, and can cause pain, nerve compression, ischaemia and limb loss. Vascular surgery is an emerging specialty under the remit of general surgery, with the primary objectives of preventing death and limb loss. This article summarises the epidemiology, investigation and management of popliteal arterial aneurysms for vascular and non-vascular trainees.
