[Initial and long term outcomes of stent implantation for iliac compression syndrome].

Abstract

OBJECTIVES:

The initial and long term outcome of stenting in the iliac vein were investigated in patients with iliac compression syndrome.

METHODS:

Iliac compression syndrome was diagnosed with venography and intravascular ultrasonography that demonstrated severe stenosis at the iliac venous compression site. Fourteen patients with symptomatic iliac compression syndrome were treated with stent implantation. The patency of the stents was examined at short and long term follow-up examinations.

RESULTS:

Thirteen patients presented with left iliac venous compression and only one patient presented with right iliac venous compression. Twelve of the 14 patients had acute deep venous thrombosis, so temporary vena cava filter implantation was performed during the procedure in these 12 patients. Procedural success was defined as less than 50% stenosis after stent implantation with good flow and without major complication (death, surgical repair for vein, or symptomatic pulmonary embolization). Procedural success was achieved in 13 of 14 patients, and these 13 patients showed improvement of symptoms. In the unsuccessful case, the compression site was resolved by stenting, but good flow was not obtained due to remaining femoral vein occlusion. The self-expandable stent was used for 6 patients, and the balloon-expandable stent was used for 8 patients. Angiographic or ultrasonographic follow up was performed in 10 patients at mean follow up of 8 months, but no restenosis was documented.

CONCLUSIONS:

Stent implantation for symptomatic iliac compression syndrome is a safe and effective procedure to resolve venous disease symptoms. Despite the small number of patients, long term outcome has been excellent in this study.
