PURPOSE: To study factors that might contribute to intraoperative proximal type I @entity1070 and to evaluate the placement of @entity2967 as a therapeutic option. METHODS: Thirty-three @entity1 (30 @entity1 ; median age 72 years, range 50-85) with @entity1028 underwent implantation of fully supported Gianturco Z-stent-based endografts (12 custom-made aortomonoiliac and 21 bifurcated Zenith devices). Ten (30%) @entity1 were treated for intraoperative proximal @entity1070 . Stent-graft oversizing and neck angulation, length, and shape were compared between @entity1 with and without leaks. RESULTS: In 9 cases, the @entity1070 were successfully treated with intraoperative placement of Palmaz stents without complications. In 1 @entity1 , a leak that was resolved intraoperatively with @entity384 reappeared 1 month later; a Palmaz stent was deployed successfully. Stent-graft oversizing did not differ significantly between @entity1 who developed proximal @entity1070 and those who did not (median 4.0 mm in both groups, p = 0.47). Median neck length was 21.0 mm in @entity1 with @entity1070 and 28.0 mm in those without (p > 0.99). Median neck angulation was 30 degrees in both groups (p = 0.33), and the presence of a conical @entity439 neck was not significantly different (2/10 versus 6/23, p > 0.99). All @entity439 remained excluded at a median follow-up of 13 months (range 6-24). CONCLUSIONS: Stent-graft oversizing and neck morphology (length, angulation, and conical shape) do not seem to correlate with the incidence of proximal type I @entity1070 . Palmaz stent placement appears to be a feasible and safe treatment option for this complication.
