Objectives:
We aimed to elucidate whether lower limb extra-fascial compartment and muscle areas affect the calf muscle pumping action on lower limbs.
Method:
This study included 90 patients (180 limbs) who underwent preoperative air plethysmography (APG) and preoperative non-contrast computed tomography (CT) of the lower limbs for diagnosis of unilateral or bilateral primary varicose veins. A correlation between cross-sectional CT images and preoperative APG was confirmed. Cross-sectional CT was used to measure the extra-fascial compartment and muscle areas of the calf. The lower limbs were divided into two groups: those that were normal and those with primary varicose veins.
Results:
The extra-fascial compartment area was significantly correlated with the ejection fraction in normal (r = 0.388, n = 53, p = 0.004) and varicose limbs (r = 0.232, n = 91, p = 0.027).
Conclusions:
In normal and varicose limbs, evaluation of ejection fraction, an indicator of muscle pumping, requires consideration of the extra-fascial compartment area.

Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
