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.
