  • Title: [So-called "spontaneous" lesions of the popliteal artery].
    Author: Miani S, De Monti M, Boneschi M, Giordanengo F.
    Journal: Minerva Cardioangiol; 1997 Nov; 45(11):531-5. PubMed ID: 9549284.
    Abstract:
    The term "spontaneous", when attributed to a stenotic or obliterative arterial lesion, could seem ambiguous and doesn't completely explain the anatomical substrate that is the basis of this morbid condition. However, it is true that injuries can occur without the patient being aware of any traumatic event, and can cause a symptomatology arising suddenly and, apparently, "spontaneously". In this study, three cases of patients observed for acute or chronic lower limb ischemia are presented. All patients were male, young and underwent an angiographic examination that demonstrated, in an otherwise normal arterial tree, filling defects or obstruction involving the popliteal artery. Two patients underwent a reconstructive surgical procedure. The third was medically treated. CAT or MNR examinations were performed in order to exclude developmental defect such as an anomalous course of popliteal artery determined by a displacement due to medial head of the gastrocnemius muscle. Actually in these three cases, a definite etiology of the arterial damage was not demonstrated and therefore it is suggested that a physical effort could have injured an already weakened arterial structure.
