Popliteal artery entrapment syndrome : ウィキペディア英語版 | Popliteal artery entrapment syndrome
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 or tendon insertions of the popliteal fossa. This repetitive trauma may result in stenotic artery degeneration, complete artery occlusion or even formation of an aneurysm. ==History== 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.
