T-stenting with small protrusion technique (TAP-stenting) for stenosed aortoiliac bifurcations with small abdominal aortas: an alternative to the classic kissing stents technique

A novel application of the culotte stent technique to bail out a jailed common iliac artery

Implanting a self-expandable stent at the ostium of the common iliac artery (CIA) may lead to coverage of the orifice of the contralateral CIA. Here, we describe a novel application of the culotte stent technique using a balloon-expandable stent to bail out an ostial stenotic legion of a jailed CIA due to prior self-expandable stent placement. The bilateral CIAs were revascularized by culotte stenting, and patency of the stents was confirmed 3 years after the procedure. The culotte stent technique was successfully applied to an ostial stenotic lesion of a jailed CIA.

Successful Endovascular Treatment of Aortoiliac Bifurcation Stenosis Using an Empirically Based T and Protrude-Stenting with Self- and Balloon-Expandable Stents

A 73-year-old woman with arteriosclerosis obliterans (ASO) was underwent a crossover stenting for an aortoiliac bifurcation from the right common iliac artery (CIA) with a self-expandable bare-metal stent (SE-BMS); however, a new stenosis later occurred just behind the bifurcation of the left CIA. An ex vivo experiment demonstrated that culotte-stenting by additional implantation of a balloon-expandable bare-metal stent (BE-BMS) through stent struts of the SE-BMS would be empirically infeasible. Although we had initially planned a T-stenting for the additional implantation of a BE-BMS in the left CIA, we finally deployed the stent in the CIA with the proximal end protruding into the previously-implanted SE-BMS through the stent struts to avoid incomplete coverage of the stenosis by reference to the ex vivo experiments. The patient has had no recurrence for 36 months.
