Small popliteal artery XXXX : are they clinically significant?

@entity1 @entity63 @entity439 @entity613 @entity158 @entity432 @entity715 @entity438
OBJECTIVE: We undertook this study to determine whether popliteal artery @entity439 diameter correlates with initial symptoms and presence of associated @entity432 . METHODS: Duplex arteriography before infrainguinal revascularization in 500 lower extremities enabled diagnosis of 34 popliteal @entity439 in 25 @entity1 (24 male, 1 female) over the last 4 years. Fourteen @entity1 (41%) had no symptoms (group 1) and 20 (59%) had symptoms (group 2) of severe @entity613 (n = 8), acute @entity63 (n = 6), @entity158 (n = 2), and tissue loss (n = 4). We compared clinical presentation with popliteal artery diameter, prevalence of @entity715 , and presence of associated @entity432 . RESULTS: @entity438 diameter averaged 2.8 +/- 0.7 cm (range, 1.8-4.5 cm) in group 1 and 2.2 +/- 0.8 cm (range, 1.3-4.0 cm) in group 2 (P <.03). @entity715 was present in 7 of 20 limbs in group 2. Four of these @entity1 also had @entity715 . Evaluation of the infrapopliteal arteries in group 1 showed three-vessel runoff in 7 limbs, two-vessel runoff in 3 limbs, one-vessel runoff in 2 limbs, and no vessel runoff in 2 limbs. However, all infrapopliteal arteries were either occluded or significantly stenotic in 14 limbs (70%). In group 2, one-vessel runoff was observed in 5 limbs, and two-vessel runoff in 1 limb. CONCLUSIONS: Smaller popliteal artery @entity439 was associated with higher incidence of @entity715 , clinical symptoms, and @entity432 . Liberal use of duplex scanning in this setting may have accounted for the increased awareness that small popliteal artery @entity439 can @entity715 and present with severe @entity63 .
