Popliteal Artery Entrapment Syndrome Presenting with Acute Limb Ischaemia: A Case Report

Table 1

Classification of PAES [7–9].

Type 1	PA has an aberrant medial
	course around the MHG which
	has a normal insertion above
	the femoral condyle.
Type 2	MHG is inserted more
	laterally on the distal femur
	but PA not displaced.
Type 3	An aberrant accessory slip of
	MHG slings around and
	surrounds the PA.
Type 4	PA is located deep in the
	popliteal fossa and entrapped
	by the popliteus muscle or
	fibrous bands.
Type 5	Any form of entrapment that
	involves both PA and PV.

MHG: medial head of gastrocnemius, PA: popliteal artery, and PV: popliteal vein.
