  • Title: Surgery and the progression of the occlusive process in patients with peripheral vascular disease.
    Author: Morris PE, Hessel SJ, Couch NP, Adams DF.
    Journal: Radiology; 1977 Aug; 124(2):343-8. PubMed ID: 877276.
    Abstract:
    The angiograms and clinical records of 42 patients with arteriosclerosis obliterans who underwent repeat angiography were analyzed in order to correlate the effects of surgery with progression of the occlusive process in native vessels. Occlusive disease progressed significantly faster in operated limbs (77%) than in nonoperated limbs (44%). When progression occurred, it was more likely to take the form of occlusion in operated limbs (85%) than in nonoperated limbs (61%). Graft closure was associated with a 93% incidence of disease progression, but even limbs with patent grafts had a more rapid progression than the nonoperated limbs (62% vs. 44%). There was a good correlation between the presence of symptoms and the angiographic progression.
