The popliteal artery entrapment syndrome
is a rather uncommon pathology
, which results into claudication
and chronic leg ischemia
. The popliteal artery
may be compressed behind the knee
, due to congenital deformity of the muscles
insertions of the popliteal space
. This repetitive trauma may result in stenotic
artery degeneration, complete artery occlusion
or even formation of an aneurysm
The syndrome was first described in 1879
by Anderson Stuart, a medical student
, in a 64-year-old male. Hamming and Vink in 1959
first described the management of the popliteal artery syndrome in a 12-year-old patient. The patient was treated with myotomy
of the medial head of the gastrocnemius muscle
and concomitant endarterectomy
of the popliteal artery. They later reported four more cases and claimed that the incidence of this pathology in patients younger than 30 years old with claudication was 40%. Servello was the first to draw attention to diminished distal pulses observed with forced plantar- or dorsiflexion in patients suffering from this syndrome. Bouhoutsos and Daskalakis in 1981
reported 45 cases of this syndrome in a population of 20,000 Greek soldiers. During the recent years the increasing frequency with which popliteal artery entrapment is reported, strongly suggests a greater awareness of the syndrome.
Love and Whelan proposed a classification of this pathology into four types, according to the various relationships between the popliteal artery and the muscles of the popliteal space. Rich and Hughes described popliteal vein
compression, thus adding a fifth type into the former classification. The functional type of the popliteal vessel compression was first described by Rignault et al. in 1985 and labeled by Levien as type VI of the popliteal vessels entrapment syndrome.
