[Endovascular treatment for obstructive disease of the aortoiliac bifurcation by the kissing stent technique].
OBJECTIVE
To evaluate short and medium-term results of endovascular repair of the aortoiliac bifurcation for occlusive disease by the kissing stent technique.


METHODS
Twenty patients were included in this retrospective study between May 1999 and November 2002 (13 men, mean age 58 years, range 42-86). Fifteen were treated for bilateral common iliac artery stenosis (75%), four for unilateral common iliac artery occlusion with or without controlateral stenosis (20%), and one for bilateral common iliac artery occlusion (5%). Each patient had a clinical examination and dupplex-scan prior to discharge, at three months, twelve months then yearly.


RESULTS
All procedures were successful. Forty balloon expandable stents were deployed in the kissing position (mean length and diameter, 45 mm and 9 mm). Nine other stents were also deployed either in the abdominal aorta (one patient) either in the lower portion of the common iliac artery. Intra-operative complications were represented by one hematoma of the groin region treated surgically, one emboli of the femoral bifurcation treated by Forgarty balloon embolectomy, three dissections of the common iliac arteries treated by stenting, and one internal iliac artery occlusion not treated. Mean follow-up was 21 months (range 3-36). Three significant restenoses (>50%) were diagnosed during this period and one patient had an additional transluminal procedure. No intra-stent occlusion was found. Primary and secondary cumulative patencies at 12 and 36 months were respectively 94.7%, 84,4% and 100%, 89%.


CONCLUSIONS
We confirm the feasibility, and the reliability of endovascular aorto-iliac kissing stent reconstruction in occlusive disease for selected patients.
