Purpose: To explore if the diameter of an occluded superficial femoral artery (SFA) can predict the technical success of percutaneous recanalization.Methods: Two hundred patients (151 men; mean age 57 ± 16 years) suffering from peripheral arterial occlusive disease were evaluated with duplex ultrasonography to measure arterial diameters and percent diameter reduction. Seventy-nine (39.5%) patients had segmental or complete SFA occlusions that ranged in age from 2 to 26 months (median 11). The majority of occlusions (45, 57.0%) were =10 cm long (range 10–35). Percutaneous recanalization was performed in 71 patients using either conventional angioplasty or local low-dose thrombolysis with rtPA.Results: Diameters of 79 unilaterally occluded SFAs at the level of occlusion were 4.5 ± 1.4 mm versus 5.7 ± 1.3 mm for the patent contralateral artery (p=0.055). None of the 121 patent SFAs had diameters =3.5 mm, but 12 (15%) of the 79 occluded SFAs did, and none of these could be recanalized. The sensitivity of the 3.5-mm cut point to predict recanalization failure was 44% (specificity 100%).Conclusions: Our data suggest that occluded SFAs with a diameter reduction to =3.5 mm are not suitable for percutaneous recanalization, as the original arterial lumen cannot be reconstructed. |
