Popliteal artery entrapment syndrome: diagnosis and management.
A variety of anatomical abnormalities may product an external compression of the popliteal artery, resulting in a thrombotic occlusion. Between 1983 and 1995, 9 patients presented a popliteal artery entrapment syndrome, bilateral in two cases. Ultrasonography, Angio-CT scan and MRI showed the abnormal structures and position of the popliteal artery on popliteal fossa. Arteriography detected an arterial compression in 6 limbs and occlusion in 4 limbs as well as an associated popliteal aneurysm in one patient and distal embolism in four. The abnormal medial head of the gastrocnemius muscle was resected in 8 limbs, while fibrous membranes were resected in 3 limbs. Autogenous vein replacement was performed in 4 cases of popliteal artery occlusion and following resection of a popliteal artery aneurysm in one case. All patients recovered. In the followup period, the occlusion of the arterial reconstruction occurred after 28 months in one patient, with a mild claudication. Noninvasive vascular imaging techniques may allow early diagnosis and management of PAES, avoiding popliteal arterial wall lesions and its occlusion, with a better outcome.
