Purpose: To report an alternative technique to the dual-lumen catheter for deployment of the Powerlink stent-graft in patients with angulated sacs and calcified aortic bifurcations. A maneuver is also presented to retrieve the delivery system when it is snagged on the stent. Technique: After cutdown of the right common femoral artery (CFA), a 9-F introducer sheath is placed percutaneously into the left CFA. A gooseneck catheter is introduced from the right CFA to capture a 0.035-inch hydrophilic guidewire inserted from the left. A 5-F straight catheter is passed over this guidewire from the left to the right CFA. In angulated aneurysm sacs, a 5-F Hunter catheter is introduced from the right femoral access to support a guidewire through the aneurysm to the suprarenal aorta. Then the guidewire is exchanged with a 0.035-inch Amplatz extra stiff wire, and the Hunter catheter is removed. In other cases, a 0.035-inch Amplatz extra stiff guidewire is placed up to the suprarenal aorta. The endograft delivery system is then deployed in the usual manner. A gooseneck snare is also useful in retrieving the delivery system when it is snagged on the stent at the endograft bifurcation. Conclusions: This variant technique facilitates the deployment of the Powerlink stent-graft when faced with angulated aneurysms or acute and calcified aortic bifurcations. A goose-neck catheter is helpful in retrieving the delivery system's "olive" after endograft placement. © 2005 by the International Society of Endovascular Specialists.
