Origin

The sural arteries arise from the popliteal artery within the popliteal fossa. The sural arteries are paired branches that arise between the superior genicular arteries and the middle genicular artery.

Course

The medial sural artery extends medially along the posterior aspect of the knee joint, deep to the medial head of the gastrocnemius.

The lateral sural artery extends laterally along the oblique popliteal ligament where it crosses over the tibial nerve. The plantaris and the lateral head of gastrocnemius sit over the lateral sural artery.

Branches

The sural arteries give off small muscular branches.

Supplied Structures

The sural arteries contribute to the supply of the superficial muscles of the posterior compartment of the leg.

Artery

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
