CT angiography is a non-invasive diagnostic tool for vascular evaluation. It is a very useful tool for peripheral arterial disease diagnosis and planning the appropriate intervention. This study is to evaluate the pelvic and lower limb arterial diameter of a healthy Saudi population.

Material(s) and Method(s):

We conducted a retrospective study of all patients examined for a CT lower limb angiography between July 2015 and December 2021. Inclusion criteria include adult asymptomatic Saudi patients with normal lower limb arteries. Exclusion criteria include symptomatic patients with vascular insufficiency, atherosclerosis, dense vascular calcifications, poor imaging technique, or incomplete data. Most of the included patients underwent CT angiography for preoperative for a fibular flap, post-trauma, or for vascular malformation evaluation. the vascular diameter was obtained using automatic and semi-automatic software. Six arterial segments were measured at pre-defined locations for each patient: common iliac, external iliac, common femoral, proximal superficial femoral, distal superficial femoral, and popliteal arteries bilaterally.


One hundred and twelve patients were included in the study, with 76 /112male (68%), mean age 38.3 (range: 18-80). Average arterial diameter as following common iliac artery (9 mm), external iliac artery (7.5 mm), common femoral artery (7.3 mm), proximal superficial femoral artery (6.11mm), distal superficial femoral artery (5.3 mm), and popliteal artery (4.8 mm). No significant difference between the right and left limbs could be observed.


We presented the reference values for different vascular pelvic and lower limb segments in a healthy Saudi population.
