M. Maynar et al., CRAGG ENDOPRO SYSTEM-I - EARLY EXPERIENCE .1. FEMORAL ARTERIES, Journal of vascular and interventional radiology, 8(2), 1997, pp. 203-207
PURPOSE: This work describes the early experience with the Cragg Endop
ro System I. The safety and efficacy of this device in the treatment o
f atherosclerotic lesions of the femoral arteries are evaluated. MATER
IALS AND METHODS: Eleven patients with complex femoral artery lesions
were treated. Ten patients presented with femoral artery occlusion and
one had a 90% stenosis, All patients had life-style limiting claudica
tion, Associated comorbid states included smoking (n = 10), hypertensi
on (n = 4), hyperlipidemia (n = 5), coronary artery disease (n = 3), a
nd diabetes (n = 1), The stents were dilated to the size of the native
artery in the first three patients, The protocol was modified and ste
nts were overdilated by 1 mm in the remaining eight patients, An antic
oagulation regimen was used in the first three patients and modified p
er protocol requirements in the remaining eight, Prophylactic antibiot
ics were given before the procedure, Follow-up studies included Dopple
r ultrasound and intravenous and intraarterial digital subtraction ang
iography. RESULTS: An antegrade femoral approach was used, Stent place
ment was successful in all patients, The mean lesion length was 9.9 cm
(4-18 cm), Mean ankle/brachial index before treatment was 0.65 and in
creased to 0.87 after treatment, Mean follow-up was 17.2 months, and o
ne patient was lost to follow-up, Complications included sepsis (n = 1
), fever (n = 2), severe pain (n = 4), thrombosis (n = 5), and hematom
a (n = 2), Stent patency was improved after protocol modifications, Ov
erall primary patency rate was 45% and secondary patency was 56%. CONC
LUSION: This early experience with the Cragg Endopro System I shows th
at recanalization of long femoral occlusions and stent-graft placement
is feasible, The primary and secondary patency rates are low and the
complication rate is high. Improved patency rates are expected with a
more aggressive anticoagulation regimen and stent overdilation.
